At DairyNZ we’ve been struck by some of the touching stories we’ve heard
of how farmers are helping each other.
We’ve heard of farmers secretly leaving baking at cowsheds of people
doing it tough, of people offering up spare rooms and home cooking in their
houses for farmers who need a break.
One farmer volunteered to host three school groups each week on his
farm to help us clear a waiting list of children wanting to visit a dairy farm as
part of our Rosie education programme.
Fifty people turned up in Taranaki to help clean up flood-hit farms.
Farmers took in extra cows that needed to be milked when paddocks were
under water in Manawatu.
Many farmers have helped us with our Tactics campaign – hosting events
and sharing knowledge, experience and tips on how to get through a low
milk price. Your knowledge and support has been invaluable.
We've got good reason to be proud of the industry we work in.
Family, friends, looking after your health, enjoying your farm and the
cows, paying it forward, doing something every day for someone else – just
as someone else does something for you, that’s what really matters, and I
think it's what our industry has always been good at.
Christmas is the time to celebrate all that kindness and generosity in this
past year. It is what counts – and we can count on that getting us through
the next year. The summer is almost here – check out the great tips in this
issue, especially the farmer stories.
I welcome your feedback. Feel free to email me at
Tim Mackle
Chief executive DairyNZ
It’s hard to believe it’s December already. While we have faced some challenging times this year, looking back, it’s not the ups and downs of the milk price that have stayed with me, it’s the people who have chipped in to help others within the industry that stand out for me.

The farm team has gained an average cover of 300kg dry matter (DM)/ha and is on track to achieving their goal of capturing an extra half tonne of DM before Christmas.
While the review visit in August ensured their pasture was in a prime position going into spring, it has also set them up for summer. “We have learnt lessons we will apply every season,” they say.
Learning how to use the Spring Rotation Planner (SRP) properly
was one of the best things to come out of the feed visit say Jens
and Leslie.
“I’ve always done grazing management and paddock
allocation by the seat of my pants,” says Jens. “It does make it
hard to teach and to know if I’m exactly on point.
“I understood the concepts of the SRP but I’d never been
talked through the detail in relation to our situation.
“Learning how to use it properly and applying it on our farm
meant Leslie and I could really nail it.
“Having a set plan to follow immediately gave us confidence.
“Once I knew how to use it, I realised it’s not hard to do. It’s
about following a plan to ensure pasture management stays on
track. It’s definitely paid off going into summer.”
A ONE-ON-ONE DAIRYNZ FEED REVIEW VISIT ON THEIR FARM HAS SET BAY OF PLENTY DAIRY FARMER OWNER JENS WULFF AND CONTRACT MILKER LESLIE COETZEE UP FOR MANAGING THROUGH WHAT IS LIKELY TO BE A DRY EL NIÑO SUMMER.
Farm owner Jens Wulff, contract milker Leslie Coetzee and DairyNZ consulting officer Kevin McKinley are “stoked” with the farm's pasture cover.

Leslie says the SRP is now their ‘go-to’ tool.
“I wouldn’t consider doing grazing management without it,”
says Leslie. “It removes the guesswork – as soon as we started
using it I felt like we were in the right position. If you’ve got a
good plan in place it’s easier to deal with tough situations when
they come your way.”
In turn, Jens says he was really happy
knowing Leslie had a robust plan to work
from.
“I would recommend all farmers sit
down with their consultant and learn
how to use the SRP to its full potential.
It makes achieving grazing management
targets a whole lot easier, especially if
there’s more than one person involved in
managing pasture.
“It’s removed a lot of stress from an already tough season and
alleviated or removed a lot of the problems we would have been
facing now.
“Knowing you can get through a feed supply shortage takes a
big weight off your mind.”
Spring Rotation Planner in practiceFor the farm team, the practical application of the SRP meant
allocating smaller breaks.
“Allocating the correct feed every day meant we were able
to increase pasture cover through winter and end up in a good
position come spring,” says Jens.
“It also meant we were allowing pasture
to get to target pre-grazing yields, ensuring
we had enough pasture for the next round,”
says Leslie.
In October, the team was happy with their
cover of 2200kg DM/ha, an average gain of
about 300kg DM/ha.
Balance date for the farm was October
10. At the start of October the farm was
on a 26 day round and since balance date they have been
shortening the round.
“With AB (artificial breeding) starting on October 19, having
adequate feed on-hand is as important as ever,” says Jens. “It’s
one of the flow-on effects of good levels of quality pasture –
we’re aiming for a good submission and conception rate.
“If you’ve got a good plan in place it’s easier
to deal with tough situations when they
come your way.”
The farm team use DairyNZ's grazing management guide to get grazing targets bang on.
Inside Dairy | December 2015 5
“We’ll start to increase feed coming into AB – and we’ve now
got plenty of pasture on-hand to do this.”
Key changes yield big results“Our main takeaway message from the feed assessment was
that we could feed slightly less per cow,” says Leslie.
“It was good getting that reassurance that the cows would be
fine on 14kg DM – it’s gaining that confidence that you don’t
have to ‘feed them heaps’.”
Pasture allocated to the milker and colostrum herds was
reduced to 14kg DM/cow (they had been allocated 16kg DM/cow
and not eating it at all) and the dry cow herd was reduced to 9kg
DM/cow.
Allocating less feed in spring meant slowing the rotation. “We
concentrated on fully utilising pasture – grazing a little bit lower
and harder,” says Leslie.
Top tips for improving pasture management
Learn how to use the Spring Rotation Planner and
use it as your shared go-to planner – it will pay
dividends.
Have a plan to follow.
Assess residuals and cover properly – no
‘guesstimating’.
Use it or lose it – meet target residuals (1500-
1600kg DM) for quality pasture.
Use DairyNZ’s pocket guide to grazing
management in spring with clear pictures and
explanations to help meet targets.
Work as a team with a shared resource such as
the Spring Rotation Planner.

“Ensuring target grazing residuals were met meant we had
enough pasture for the next round of grazing.”
Jens says if they hadn’t made the changes they might have
matched production up to start of October but they would have
been left with no pasture heading into mating and the worry of
‘where to’ next.
“We wouldn’t have been able to maintain production and it
would have cost us more in supplements,” says Jens.
“Instead, cows remained in good condition and we have
peace of mind knowing there is adequate feed going in to
summer.
“We’re concentrating on a pasture-first mentality and getting
grazing right; we know that’s what gives the best returns in the
long run.
“We weren’t way off track, but some key changes meant we
were able to maintain adequate pasture cover going into spring
and be well set up for summer.”
Dry summer preparationIn preparation for a dry summer, a crop of turnips will be
fed from January 20 onwards for about six weeks, followed by
maize silage.
“We’re doing turnips instead of PKE this year as it’s a
cheaper feed, plus we’ll get the new grass from that,” says
Jens.
“We usually manage to stay on a 21 day round all year quite
comfortably and stay milking twice a day for the majority of the
season,” says Jens.
Heifers are on once-a-day (OAD) until the end of AB and
we winter the cows off-farm from June 1 in three mobs on
separate properties.
Feed review visitJens says the opportunity to have the on-farm pasture
assessment couldn’t have come at a better time.
“We usually try to go into winter with an average cover of
2000kg DM/ha. Instead, we were sitting at about 1800kg DM/
ha. We knew we were going to be in trouble if we kept going
the way we were.
“It was very beneficial having a consultant on-farm to see
the real situation. We received guidance to point us in the right
direction and reassurance where we were on the right track.”
The team’s farm visit was held on August 3 with their local
consulting officer Kevin McKinley.
“It’s removed a lot of stress from an already tough season and alleviated or removed a lot of the problems we would have been facing now.”

Don't be caught short Managing feed supply this summerInformed feed supply decisions made in early December can help ensure the herd’s production remains profitable for the remainder of the season. DairyNZ developer Sean McCarthy provides insights and points to new resources that will help you make the best decisions over the next few months to ensure feed supply is managed in an effective way.
Ensuring feed supply matches demand, for many, will mean
continuing to meet pre-grazing leaf stage and post-grazing
residual targets to encourage as much pasture growth as
possible. It may also include the use of summer crops, nitrogen
(N) fertiliser and supplements where it makes economic sense.
Assuming sensible culling and dry off decisions are made to
manage feed demand, the focus shifts to supplying high quality,
low cost feed.
Before culling and dry off decisions can be made, it is
important to have the right information. Knowing the average
pasture cover and feed on-hand will enable you to determine
if a lift in farm cover is required and whether December is a
good time to apply N fertiliser to encourage greater growth
rates in early summer. N boosted pasture is a valuable feed
source, and even if ensiling is required, it will cost less than
many supplements (for an evaluation framework, see the article
Supplements, surpluses and savings, pg 12, Inside Dairy October
2015).
Slowing grazing roundA dry summer will slow pasture growth, so slowing down the
round in early December by increasing the number of days in
the rotation will help achieve maximum growth during summer
and help ensure there is adequate feed ahead of your herd for
grazing. It will also allow for grazing of pastures closer to the
target three-leaf stage, therefore capturing the 40-50 percent of
the high quality leaf growth from the second to third leaf (see
Perennial ryegrass grazing management booklet at dairynz.co.nz/
grazing-management).
Target residuals for high quality pastureThe way to increase feed is by a slower rotation, not higher
residuals. There is a misconception that leaving higher residuals
in December will increase feed availability in summer and help
capture moisture. Leaves have a limited lifespan so higher residuals
will in fact reduce pasture growth and any remaining high
quality feed will decay and not be available later in the summer.
8 Inside Dairy | December 2015
Therefore, leaving high residuals in December won’t help fill a
feed deficit later on; it will simply result in wasted pasture now
and reduced pasture growth and quality in the months ahead.
Residuals of 1500-1600kg DM/ha will ensure the plant
maintains its energy reserves and will provide some shading of
the soil surface.
Feeding summer cropsWhile the area in crop has by now been determined, it is
important to measure and monitor yields so this feed is allocated
accurately. Information on managing and feeding individual
crops can be found at dairynz.co.nz/crops.
Ask why before you buy Decision rules around feeding supplements need to be
made alongside knowledge of overall expected feed supply and
demand (see article on reviewing herd numbers on pg 10).
DairyNZ’s new “Summer Feeding Check” worksheet will take
you through the steps to work out when you will get a good
financial return from using supplements.
The “Weekly feed management check” template included will
help you monitor grazing indicators (pre-grazing yield, rotation
length, average farm cover, post-grazing residuals) alongside
supplement use to determine whether or not money will be made
from feeding supplement.
It also provides a checklist of questions that need to be
considered before supplement is purchased.
The worksheet can be downloaded from dairynz.co.nz/
publications/feed.
Supplement use after culling decisionsDairyNZ’s online Supplement Price Calculator will help you
determine how much you can pay for supplementary feed during
a shortage. It provides a more detailed output with regards to
different feed types, amounts and time of the year.
It must be noted that the milk response in these resources is
determined based on energy being the limiting factor to milk
production. While this is typically the case when cows are eating
high quality pasture, in summer/early autumn the availability
and quality of the pasture declines and the use of low protein
supplements (e.g. maize silage, fodder beet) increases. Therefore
in some instances protein may be limiting milk production.
However, protein supplements are usually expensive and even
with a milk response, the extra milk revenue does not typically
outweigh the cost of feeding a protein supplement (See article
Should I supplement with protein in summer? pg 26 in Inside
Dairy February 2015).
Another factor to consider if using large amounts of
supplements in summer is to ensure cows have adequate effective
fibre. For example, although PKE is high in neutral detergent
fibre (NDF), it contains no effective fibre. From a rumen health
perspective, a forage source (pasture, straw, hay) may need to be
included in the diet if PKE is being fed. For more information see
DairyNZ’s FeedRight booklet at dairynz.co.nz/publications/feed.

Reviewing herd numbers for the best returnsManaging through a drought or very dry summer requires two key outcomes to be kept in mind; keeping some cows in milk for when it rains and protecting next season.
DairyNZ feed and farm systems specialist Kim Mashlan says with a predicted El Niño summer in some parts of the country, and low milk prices, now is the time to review the expected feed situation and herd numbers.
Planned decision rules around early culling, early dry off and
selective dry off, as ways to reduce feed demand, ensure clarity
for the business and lower the stress of having to make quick
decisions in a difficult environment.
When faced with a shortage of feed there are two options;
reduce the feed demand or increase the feed supply. Here we
consider reducing feed demand options.
Early cullingThe first decision to make about culling is “What could be
culled early?” e.g. obvious culls, empties and voluntary culls.
To calculate the number of voluntary culls, take current cow
numbers on hand and add the number of in-calf heifers to enter
the herd on June 1. From that figure, subtract the number of
empties, the number of known culls (e.g. persistent mastitis,

lameness etc) and deaths. The difference between that figure
and the minimum number required to winter is the number of
voluntary cull cows.
The second question is “What feed would these animals
require if they remained milking?”
When an animal is culled, extra feed is available for the
remaining cows, meaning less supplements are required to cover
the feed deficit. Therefore the marginal benefit is the saving
on supplement not purchased, minus the lost revenue from the
culled cow’s milk production.
Thirdly, the value that selling culls early will have on cashflow
could be considered, and is obviously impacted by the beef
schedule with early culls typically worth more than late culls.
Though not a large amount, this equates to a further $23/animal
reduction in interest in the example below.
The example in Table 1 indicates where culls are producing
less than the herd average (in this case 20 percent less) and
supplements cost $350/t, it was more profitable to cull the
animal than buying in feed to keep it milking.
The breakeven price for supplement, where it could be
worthwhile buying in supplements to keep milking the cull would
be $290/t eaten in the above example. Remember this is after
you have allowed for wastage. If wastage was assumed to be 10
percent more, then the amount you can afford to pay, including
delivery, is $261/t. At 20 percent more wastage then the amount
you can afford to pay is only $232/t before it is better to cull
animals, based on the example above.
Early dry off of whole herdModelling (using Farmax) was used to look at the impact
of very early and early dry off of the whole herd for a typical
farm in both Canterbury and Waikato under pasture growth
rates for a typical El Niño year. The results indicated very early
dry off (milked for 182 days and dried off end of February)
was not profitable, even at a $4/kg MS milk price. This is not
recommended.
The early dry off option milked for 237 days and was
marginally better than milking to the normal dry off time (267
days) if some of the cow related variable costs (dairy shed
costs, electricity, labour, machinery and fuel) could be reduced.
Decisions like this need to be done for your own farm with input
from advisors.
Evaluating the worth of selective dry offSelective dry off is when some of the cows are progressively
dried off through the later part of the season to match feed
demand and supply and to ensure body condition score and
pasture targets are met.

website in late January) evaluates the options of selective dry off
compared with continuing to milk the whole herd and buying in
more feed.
The calculator takes into account the expected pasture
growth rates, body condition score targets, the type and cost
of supplements needed, (feeding out costs and utilisation),
milk price and expected response to supplements. Using this
calculator shows how feed type and costs can alter the margin
between milking on versus a staggered dry off (Table 3) and
effect on achieving target pasture covers and body condition
scores.
The mix of feeds used and the price/tonne has the biggest
impact on whether it is better to selectively dry off or continue
buying in feed.
In Table 3, Feed options 1 and 2, result in a higher margin if
all cows are kept milking and feed is purchased than if cows are
selectively dried off.
However, a change in feed type and price, shown in Feed
Option 3, means although both milking on and selective dry off
provide a positive return it would be better to selectively dry off.
If low producers are selectively dried off, then this feed, if used
by the remaining herd, would increase milksolids production.
Due to the many factors that need to be considered when
making these decisions it is important to use tools like this
calculator to estimate the returns for your own farm.

grass roots
At this point in the season farmers have put a lot of effort into managing pastures to ensure they are in a good state for summer. DairyNZ scientist Cáthal Wims explains the need to continue the focus on grazing management through summer, with particular emphasis on tightly controlling post-grazing residuals.
Summer pasture management
As pasture supply reduces over the summer months it’s
important to think about how to avoid overgrazing; which occurs
when pastures are grazed below 7-8 clicks (as measured on the
rising plate meter).
This summer’s weather prediction for an El Niño will bring
drier conditions in the north and east and below average pasture
growth rates to some areas (see mpi.govt.nz).
The temptation during dry summer months is to harvest more
pasture by grazing cows to residuals of less than 7-8 clicks, but
this practice is detrimental to pasture recovery following the
autumn rain and the longer term persistence of the pasture.
The summer and early autumn period is generally the most
stressful on non-irrigated pastures. As well as the drier conditions
and higher temperatures typically experienced during the
summer months, perennial ryegrass pastures can be subject to
additional pressure from insect pests.
Avoid overgrazing Pastures will be subject to further stress if overgrazed.
Perennial ryegrass maintains energy reserves which are stored in
the 4-5cm of plant above ground level (the stubble). The plant
uses these energy reserves during the initial stages of regrowth
to regain leaf area.
Summer overgrazing depletes these energy reserves resulting
in reduced pasture recovery following the autumn rain, and
severe or repeated overgrazing can result in plant death which
will have negative consequences for the longer term persistence
of the pasture.
Early December is a good time to think about managing
pasture residuals over the summer, which unlike the weather
and insect pests, are under farmers’ direct control. Think about
the level of supplement you have on hand, consider options to
reduce demand (e.g. culling, see pg 10) and develop a plan to
manage residuals to 7-8 clicks and don’t let them get below this
during the summer – it will pay dividends in the autumn.
Nitrogen applicationNitrogen application is a relatively cheap way to gain
additional feed and applying 25-35kg N/ha in late spring/early
summer (moisture permitting) will help boost pasture supply over
the coming months. In addition, nitrogen application in early
summer will boost the growth of new perennial ryegrass tillers,
or ‘daughter tillers’, which will help thicken up the pasture going
into summer.

Once-a-day milking post Christmas Latest research by DairyNZ senior scientists Jane Kay and Claire Phyn provides valuable insights on what to expect for farmers considering once-a-day (OAD) milking post-Christmas.
Christmas often marks a waypoint in the dairying calendar
for deciding how best to approach the remaining four to five
months of the season.
Reduced milk returns and the strong likelihood of an El
Niño weather pattern delivering dry weather for farmers from
Northland down to the east coast, have seen many farmers
approaching DairyNZ about the economics and practicalities of
going to OAD milking post-Christmas.
Results from OAD milking trialFrom January 2013 until the end of lactation, 52 crossbreed
cows were split into two herds, one milked twice a day (TAD)
and the other OAD. Cows’ feed intake was analysed, along with
milk production, somatic cell count (SCC) and body condition
score (BCS) gain.
The trial discovered production per cow dropped 10 percent
while cows were being milked OAD.
In this particular trial, the 10 percent loss in milksolids
production occurred when production was past its peak and
cows had already delivered about two thirds of their season’s
total yield. This meant the overall impact on the season’s
production was approximately four percent.
Small decline in feed intake The trial found the decline in feed intake by the OAD herd
was not as great as expected. Cows milked OAD ate about three
percent less than cows milked TAD, says Jane.
This small decrease in intake needs to be considered if milking
OAD during a dry summer. With similar intake levels, but with
less energy being put into milk production, the OAD herd was
in a better energetic state. This resulted in OAD cows being on
average a quarter of a BCS unit more at dry off than the TAD
cows.
“This meant cows being milked OAD in late lactation had
Once-a-day (OAD) milking compared
with twice-a-day (TAD) for three
months in late lactation:
• 10% decrease in milksolids production
(while cows were on OAD)
• ¼ body condition score (BCS) unit
increase at dry off
• Approximately 3% decrease in intake
KEY RESULTS
14 Inside Dairy | December 2015
Once-a-day part of summer routineThe big drought of 2007-08 prompted Waikato
sharemilker Mark van Hellemond to try putting his herd on
OAD milking for the first time.
“It was almost unheard of at the time to consider going
OAD after Christmas, but that is how dry it was that year,”
says Mark. “We felt it was the best option to try and
continue milking in a season where the dry had come very
early.”
Since then he has not looked back, and now the herd goes
OAD early January every season.
Mark’s 460 head herd of larger Friesian cross cows are
typically producing 1.7kg MS a cow a day when he switches
to OAD.
“We only get a small drop in production, usually by about
0.2kg MS (to 1.5kg MS/cow/day). They will sit on that until
March when they drop to 1.3kg MS, then down to 1.2kg MS
in April.”
“I go to OAD before feed tightens up and before I have to
start feeding supplement, putting them on 24 hour grazing.”
Mark maintains the 11 percent drop gets channelled into
body condition instead.
That in turn reduces the need to increase condition score
over winter, has the cows peaking higher the following
spring and achieving better cycling and in-calf rates. He
regularly achieves the national goal of 78 percent in calf
within six weeks.
He knows his bulk somatic cell count will double the
first day he starts OAD milking, but settles back to the TAD
average after three days.
“If you leave going OAD too long and milk volumes have
already dropped down to 1.2kg MS or below, then you will
run into problems.”
This season’s lower milk price had prompted him to
consider OAD before Christmas.
“But that’s pretty hard to do when your cows are still
producing 2kg MS/cow/day.
“Going OAD is hard that first year, you do forgo a bit of
production, but you can make it up the following season
with better cow condition into spring.”
slightly less BCS to gain through the dry period in order to
achieve BCS targets at calving” says Jane.
“The BCS improvement does take time though; it wasn’t
until after six weeks of OAD milking that there were detectable
differences in BCS.”
Although SCC was not greatly affected in this trial, it did
increase in OAD cows as lactation progressed and milk volume
decreased. The impact on SCC of switching cows to OAD milking
in mid/late lactation needs to be considered, especially in the first
few days.
“The bulk tank SCC needs to be able to double without
grading when cows are switched to OAD. Cows with mastitis or
high SCC are not good candidates for OAD milking and should
be either dried off or continued to be milked TAD” recommends
Claire.
Alternatively, the switch to OAD can be staggered over several
days to prevent a large spike in SCC.
DairyNZ researchers have also dispelled the “mammary
memory” myth that implies putting a cow on OAD will negatively
impact on future lactations.
“We followed the cows that had been milked OAD into the
next season and there was no reduction in milksolids yield when
they commenced TAD milking again after calving” says Jane.
“If anything, these cows will have a higher BCS at dry off,
are more likely to reach the BCS targets at calving and reap the
production and reproduction benefits of this,” says Claire.
Milking the cows OAD also did not extend the cows’ days in
milk.
“When we used drying off decisions based on milk production
and BCS, the OAD cows were dried off in slightly better
condition, but did not milk longer.”
If contemplating milking OAD post christmas, these
performance factors need to be considered alongside other farm
specific variables such as lifestyle and milking associated costs.

Take five Ways to stay well this summer
DairyNZ’s Sarah Tully is involved in developing DairyNZ’s Farmer Wellness and Wellbeing programme. Sarah, along with husband Ciarán, is a dairy farmer in Thames. Here she talks about what farmers can do to stay healthy and strong.
“Those who do not make time for wellness will eventually be
forced to take time for illness,” is a quote worth bearing in mind.
As farmers, there is always something going on so it is unlikely
that we ‘find the time’ – it has to be made a priority.
There are five key components of wellness as shown in the
diagram below. Spending time on these will help you meet the
demands of work, be sharp in the face of challenges and change
and get more enjoyment from life.
Connect and give – simply spend time with people you enjoy
being around, or attend functions or discussion groups. You
could volunteer your time to groups that your kids or grandkids
are involved in.
Keep learning – how about using some television time to
instead read things which stimulate your mind – we receive
plenty through the mail! Try surprising yourself by learning new
skills; many schools run evening classes for adults. Maybe finish a
project that’s been sitting in the garage for ages?
Be safe – have a culture of safety around your business, staff
and family. Are your insurances up to date? Do you have back-
up plans and contingencies in place for volatile times?
Rest and take notice – do you pay attention to the simple
things or just be ‘in the moment’? Often we are too busy
thinking ahead on our ‘to do’ list. Holidays and breaks don’t
need to cost the earth, but getting off-farm is a must. Try not to
underestimate the restorative power of sleep either.
Be active and eat well – try not to always choose the
motorbike, could you walk to get the cows? Good nutrition really
helps our bodies regenerate – think lean protein and three veg.
If you do feel a ‘downer’ coming on, be proactive about moving
your mood. It’s ok to talk to someone about how you’re feeling –
chances are you’re not alone.
Now, coming up to Christmas and New Year is a great time to
sit down and think about how you will focus on your wellness.
Focus on one thing at a time if you have to. Remember wellness
takes time.

Keeping the big picture in focus
Keeping an eye on the big picture has helped Leo Pekar
and his partner Maricel overcome a case of bad timing.
This year they moved from a lower order sharemilking role
into 50:50. This coincided with a record low milk price and a
very wet June, when Invercargill recorded 120 percent more
rain than normal.
The couple have learnt to keep things in perspective and
ride the ups and downs of dairying to maintain balance.
“Don’t forget the big picture, do things that are
inspirational to you and give you a break from farming.
Remain positive and support others,” says Leo.
Leo and Maricel, who farm in Waikaka Valley near Gore,
have an eight year plan which helps guide their decisions in
their new 50:50 role.
“It’s important for us to focus on our eight year plan. I
thought to myself, it would be ridiculous to think that all
those eight years would be rosy – there is going to be a
tough one.”
Leo emphasises the importance of taking time out from
the farm. For him, listening to music and going mountain
biking with friends is a great release.
With two children; Ailin (11) and Iara (8), the couple know
to leave work at the door. “We are ambitious but we aren’t
going to do it at a cost to the family,” says Leo.
Dairy farmers Leo Pekar from Southland and Robert Ervine from Wairarapa share how they have managed to stay positive during a very challenging year. They are two of 29 farmers who are sharing their experiences in facing a low milk price as part of DairyNZ’s Tactics campaign.
Taking time out
Robert Ervine is taking two floods, a low milk price and
the threat of an El Niño effected summer in his stride this
season.
Over the years the Rangiotu farm owner has developed
strategies to cope with events beyond his control, so even
when facing a tough year, he has the tools to respond.
“Having had some fairly high stress periods in life you
hopefully learn some skills to negate them so that if things
are getting tough you have ways of dealing with it,” says
Robert.
About 10 years ago, after suffering a marriage break-up,
Robert had to take a step back from farming.
“During that period of life, I finished up with ‘brown out’.
It wasn’t burn out, but it was close.”
“Taking some time off and just smelling the roses allowed
me to pull my life back together. I recognise the signs of burn
out more now. If I am making poor decisions, or not making
any decisions at all, that is usually the time to take a break .”

Grazing heifers off-farm: how does it stack up?Heifer grazing is a major expense and the quality of heifers entering the milking herd will have a significant impact on future milk production and farm income. For these reasons, the farm policy of grazing heifers off-farm warrants regular review. DairyNZ productivity team leader Rob Brazendale provides steps for comparing costs with the value received.
When reviewing a heifer grazing policy, two key questions
should be addressed:
• Should my replacement heifers be grazed off-farm or grazed
on the milking platform?
• Am I getting value for money from my grazier?
Grazing off versus on the milking platformIf heifers are grazed on the milking platform, the number of
cows milked will need to be reduced by around 0.7 cows for
every heifer to match the extra feed needed. i.e. if 100 heifers
are run on the milking platform, cow numbers should be reduced
by 70 cows.
The value of running heifers on the milking platform depends
on the milk price, production/cow and the cost of grazing.
A partial budget template has been developed to help farmers
evaluate grazing on the milking platform and is available at
dairynz.co.nz/heifer-partial-budget.
As a guideline, the breakeven price for heifer grazing on the
milking platform is shown in Table 1, using different milk prices
and production/cow levels.
Table 1
Breakeven heifer grazing costs ($/heifer/week) at different milk production levels and milk prices

$6.00 MS $15.40 $16.50 $17.60 $19.10
Heifers aged 9 months to 21 months
Added value from graziersFactors other than economics, such as your own workload and
focus, also need to be considered when working out the value of
grazing on the milking platform compared to off-farm.
The milking herd is the primary focus for dairy farm managers
and heifers can become the forgotten stock class, whereas
quality heifer graziers are highly focused on this stock class.
If you have a grazier who is doing a quality job and returning
heifers at or above target liveweights, breaking this relationship
during low milk price times may be difficult if not impossible to
restore when better milk prices return.
Am I getting value for money from my grazier?When reviewing heifer grazing options, the value of grazing
needs to be compared with its costs. Low cost grazing is not
necessarily good value, just as paying ‘top dollar’ for grazing
does not guarantee top results. Two examples on the following
page demonstrate cost versus value.
18 Inside Dairy | December 2015
Lower cost of grazing with heifers coming back under target weight
Crossbred heifers are grazed off the milking platform
from December for 78 weeks (to the following May).
Average start weight: 100kg
Grazing cost: $7.50/week for R1 (rising one year olds)
(first 26 weeks); $9/week for R2 (52 weeks)
Heifers return to the milking platform at an average
weight of 350kg, which is 50kg below target for their age.
Working out cost of grazing
26 weeks x $7.50/week = $195
52 weeks x $9.00/week = $468
Total cost of grazing = $663/animal
Weight gain
350kg on return – 100kg at start of grazing = 250kg Lwt
gain/animal
Value of grazing per animal
Cost of grazing / weight gain = value of grazing/kg Lwt gain
$663 / 250kg weight gain = $2.65/kg Lwt gain
Higher cost of grazing with heifers coming back above target weight
Crossbred heifers are grazed off the milking platform
from December for 78 weeks (to the following May).
Average start weight: 100kg
Grazing cost: $10.50/week for R1 (26 weeks); $12.50/
week for R2 (52 weeks)
Heifers return to the milking platform at an average of
450kg, which is 50kg above weight target for their age.
Working out cost of grazing
26 weeks x $10.50/week = $273
52 weeks x $12.50/week = $650
Total cost of grazing = $923/animal
Weight gain
450kg on return – 100kg at start of grazing = 350kg Lwt
gain/animal
Value of grazing per animal
Cost of grazing / weight gain = value of grazing/kg Lwt gain
$923 / 350kg weight gain = $2.64/kg Lwt gain
Although the second example is 30 percent more expensive up
front, the immediate value for money is similar and the long term
benefits also make the value greater over time.
For many dairy farm businesses, the policy of grazing heifers
off-farm remains a profitable strategy, even at relatively low milk
price levels.
DairyNZ heifer grazing projectDairyNZ is leading a heifer grazing project that aims to improve
the growth of young stock, in-calf rates and the dairy farmer-
grazier relationship.
The project is being led in partnership with dairy farmers,
graziers, Beef + Lamb, LIC and other industry partners, with five
focus farms established around the country.

Building this season's lessons into long term profits2015 will go down in memory as one of the toughest seasons in the last 25 years. DairyNZ business specialist Lynaire Ryan considers it will be a pivotal year for setting the platform for how businesses are run in the future.
Average Farm Working Expenses (FWE)
have increased from $2.50/kg MS in
2000 to $4.35/kg MS in 2014 (as shown
in Figure 1). From 2000 to 2006, FWE
averaged around $2.50/kg MS.
In 2007/08 the milk price reached
a record high, above $7/kg MS. A
fundamental change in expenditure
occurred with FWE increasing by more
than $1/kg MS. Feed costs were the
largest contributor to the increase in FWE.
The last two seasons have seen
reduced expenditure, with many farmers
targeting costs between $3 and $3.50.
Understandably some cost reductions are
one-off and not sustainable over the long
term.
This is an opportunity for the industry
to make a fundamental adjustment and
focus on retaining FWE around $3.50
going into the future. The focus would
move to maintaining a low cost structure
and increasing the profit margin as the
milk price lifts.
Detailed budgets sharedMany dairy farmers already operate
their business like this. Several top
performing dairy farms achieving FWE
below $3.50/kg MS have shared their
detailed 2015/16 budgets on the DairyNZ
website for farmers to compare costs.
These businesses have learnt lessons
from the past and built resilient systems
to survive at a low milk price, with little
change in costs at a high milk price,
except to bank bigger profits. The key
points these farmers demonstrate include:
• clearly defined business and farming
principles that deliver a profitable
business
• a strong focus on maximising pasture
growth and utilisation, regardless of
system operated
• an emphasis on budgeting and regular
monitoring of budgets
• simple and repeatable systems which are
clearly understood by the farm team.
The case study of a Canterbury system
3 top farmer, aims to keep FWE around
$3.40/kg MS consistently. Very little
change is required between a ‘good’ and
‘bad’ year. In the high milk price year of
2013/14, their FWE were $3.67/kg MS.
This season they have budgeted on
FWE of $3.10/kg MS. When the milk price
dropped they only needed to make minor
adjustments, so the drop was not a major
stressor. The most significant reduction
was in fertiliser, with minor savings in
animal health, breeding and herd testing.
Take advantage of the changes you
have made during this challenging season
and build a sustainable business which is
profitable at a $5 milk price, not $6.00, as
many farmers previously budgeted on.
If the medium term milk price
forecasters are correct, then great – bank
or invest the extra $1.50. If forecasters are
wrong, then the business will be in a more
stable position to weather the storms.

New waterways web section helping farmers future proof
A new waterways
section on DairyNZ’s
website has been
designed to help farmers improve water quality and
get the best value for money when investing in the
environment.
It provides step-by-step actions for fencing and
planting waterways, controlling erosion, protecting
wetlands, constructing crossings and managing drains to
reduce the amount of sediment, nitrogen and effluent
entering waterways.
A supporting planting guide for each region will help
farmers nail down the best planting options for their

News scoopNew Zealand’s dairy story
Fancy a virtual flight around the globe so you can
discover where in the world your milk goes? Try out the
DairyNZ online interactive model which visualises data
about dairying in New Zealand in a three dimensional
model using gaming technology.
DairyNZ’s brand marketing manager Andrew Fraser says
the new tool tells the New Zealand dairy story in a way that
makes it easy to understand and interesting to view.
“We will use this with teachers as we are developing
new educational resources for schools that use the 3D
Dairy model as a source of information,” says Andrew.
“When regional production and dairy herd statistics
are updated each year, we will be sending journalists to
the model to view the latest information. We will also
use this with key stakeholders who are not familiar with
the scale and scope of the industry. The general public
and all our industry partners can view it too.
“We think it is world leading. We have not seen online
models anywhere else that present this amount of data
in such a simple and interactive manner. It takes tables
of data and turns them into interactive information that
has more context – giving it much wider appeal than just
looking at statistics on a page.”

Farm nutrient managementNutrient managementDiscuss with your nutrient management advisor (or fertiliser representative) ways to improve the efficiency of nutrient use on-farm. Three useful indicators to look at are:N conversion efficiency: describes the proportion of nitrogen (N) going into
your farm that is converted to N in saleable product (primarily milk). N leaching loss: kg N/ha/yr. Estimate of the amount of nitrogen leached from
the farm from soil and drainage water. P runoff: kg P/ha/yr. Estimate of the amount of P lost from the farm.Options to improve• Better effluent management: applying the right amount of effluent
at the right time will ensure the nutrients in effluent are kept in the root zone and utilised by plants.
• Optimise soil fertility: make sure your soil fertility levels are in the target
range, and apply fertiliser only where necessary to maintain optimal levels.
Look at soil test graphs in your nutrient management plan. Are they in the
right range? Seek advice from your nutrient management advisor if you are outside the agronomic optimums.• Better fertiliser management: match fertiliser N inputs to feed budgets
and pasture growth rate. Avoid applying when pasture growth is low (too cold, soil temparature less than 7°C). Use non-N alternatives to boost pasture production (e.g. gibberellic acid).• Use other mitigation options: consider other practices and technologies
to further improve nutrient use efficiency and reduce environmental impact.
To protect pasture and soils, use on-off grazing when wet; waterway fencing and planting; improve feed conversion; winter management systems
etc. Visit dairynz.co.nz/nutrientmanagement.Effluent management• Effluent storage: storage capacity is critical to managing effluent
system risk. Keep the ponds empty by applying effluent at all available opportunities. If the pond is full, you have no storage.• System management: utilise the regional Compliance Checklist to
identify areas where you may be at risk of non-compliance or where improvements could be made. Seek advice to remedy any aspects that need attention. Walk the effluent system regularly to make sure there are no areas requiring attention.
Tip For more information, visit the publications section (environment) at dairynz.co.nz and the DairyNZ Compliance Checklist dairynz.co.nz/checklists.Managing team motivation
Take time to celebrate the end of calving and mating with your team. Think about ways to keep motivation high over the next few months. ReviewCapture feedback from your team on:• what went well over calving and mating?• what could be done better next time?This information helps to fine-tune what you do and helps the team understand
what ‘good’ looks like.
FeedbackComplete performance appraisals. This is an opportunity to:• give feedback to your team so they know what they are doing well and
areas to keep working on• identify the skills and experience for your team to develop to improve
business performance. Also talk about the skills they would like to build• work with your staff to develop a training plan to meet these needs.
Consider both on and off-farm training• don’t forget you are part of the team! Ask staff and other observers for feedback on your performance and build a personal training plan too.
Tip Use the performance appraisal templates for different farm roles found in
DairyNZ’s Quickstart People Productivity Kit dairynz.co.nz/quickstart.TrainingOnce you have identified training, make sure it happens. To help your people get
the most out of it make sure they know:• why they are attending• what you expect them to do differently• how you will support them to put this learning into practice.Tip Get training tips at dairynz.co.nz/people.Time-off
• With your team, plan holidays and the roster through to late January. With
staff away, the workload can greatly increase for those still at work. Make
sure this is managed carefully.
Reviewing the season so far• Are you on track to achieve your goals for the season and beyond? It’s
not too late to request a copy of the DairyNZ QuickPlan booklets to guide you through this process, helping develop a written plan in less than two hours. Visit dairynz.co.nz/quickplan or call 0800 4 DairyNZ (0800 4 324 7969).
• Keep your records up-to-date – staying on top of things during the year will make end of year accounting and reconciliations easier. Now is a good
time to update your DairyBase Level 2 recording workbook.• Review and update your cashflow, monitoring the budget and using it as a
decision tool will help with cashflow management. • Using the updated budget, take a look at your overdraft limit. • Many people are receiving a copy of their annual accounts. Have you
considered inviting your key professionals to discuss where your business is going, how it is performing and ideas for improvement? An informal AGM bringing your accountant, banker and farm consultant together can be extremely useful.
• Year-end accounts should be complete. Talk to your accountant about provisional tax planning. Get the maximum value from these accounts by having them entered into DairyBase (dairynz.co.nz/dairybase).
Pasture quality vital for summerMaintain a consistent, even grazing height going into summer i.e. clumps are
grazed into. Pasture quality has a big impact on summer production.Paddocks above the targeted pre-graze level (2800-3200kg DM/ha) should be
dropped from the rotation for silage. Increasing residuals is not advised, as:• ungrazed leaves are less efficient at capturing sunlight and die before the next grazing, reducing feed utilisation and the amount of feed grown
• when it rains, dead plant material rots and is lost• it increases the risk of facial eczema. When cows graze to a lower residual after a period of higher residuals: • energy intake per cow is reduced, due to the lower quality feed eaten• pasture plants have a reduced chance of survival, due to being grazed
below their growing point• pasture growth and persistence are reduced because pasture reserves for
growth are depleted• the risk of facial eczema increases.Consider applying 30kg N/ha in late November/early December.• N going into summer promotes vegetative tiller growth and ryegrass
persistence.• If the farm is prone to summer dry, N application coupled with longer
rotations (27-30 days), will improve feed availability through late January and February.
Irrigated and summer ‘safe’ farms should:• monitor pasture cover and maintain quality by keeping pre-graze and post-graze pasture at recommended levels• continue to harvest a surplus by making small, light silage crops – reducing
the chance of creating a feed shortage• consider applying N during December, to ensure new tillers are vigorous going into summer.
Tip For more information visit dairynz.co.nz/pasture.Other farms• These farms should already be on summer rotation lengths and have a
summer action plan in place.
Tracking herd reproduction• Track early mating progress using your Fertility Focus Report from about
week four of mating. Reassess bull requirements, in light of estimated 6-week in-calf rate performance.• Re-check calf and heifer liveweight targets and involve graziers in a plan
to achieve growth rate targets during summer and autumn. Use liveweight
BV formula (mature cow liveweight = 500kg + Lwt BV) to customise weight-for-age targets for each age group (InCalf Book pg 42-44).
• Choose a pregnancy testing strategy based on your information needs. Decide maximum total length of mating (12 weeks). Accurate expected calving dates are essential for next season’s plans and can be obtained by early aged pregnancy testing. Contact your vet beforehand.
• Enter foetal aged pregnancy test records to get a detailed InCalf Fertility Focus Report. Review past performance and prioritise, with advisor input, the areas to improve such as calving pattern and heifer rearing.
For more information visit dairynz.co.nz/incalf.
Wise supplement use• Remove genuine culls before feeding supplements. • Calculate the amount you can afford to pay for supplement, using the
online DairyNZ supplement calculator which accounts for wastage, milk response and required profit.
• Feed supplements only when cows are grazing less than 7 clicks on the RPM or 1500 kg DM/ha, using the winter formula.Tip Refer to the ‘response to summer feed’ table in DairyNZ Facts & Figures, pg 33.Monitoring cow healthMastitis management• A rough guide to what your SCC (somatic cell count) at drying off will be,
is twice the SCC on peak day.• Look out for bulk milk SCC spikes and strip cows to find new mastitis clinical cases for treatment.
• Strip high SCC cows (>500,000/ml) after each herd test. Treat clinicals only.• Watch for signs of contagious spread e.g. growing number of heifers with
a SCC over 120,000/ml. Get expert help to review your systems.• Keep using MRS T to ‘mark, record, separate and treat’ clinical cows. Make
sure all staff know your marking systems.• Continue teat spraying after every milking. Check coverage and volume being used each month (should be about 20ml per cow per milking).
• Check teat condition. If teats are not supple, add emollient to the teat spray – 10% of the mix, by replacing the same amount of water.
• Replace inflations after 2500 milkings. This may mean replacing inflations every two months in a ‘swing-over’ herringbone milking 10 rows per side per milking, or every four months for a rotary milking 10 rounds per milking.
Tip Refer to DairyNZ Healthy Udder for more information or visit dairynz.co.nz/smartsamm.Facial eczema• Start monitoring spore counts and begin zinc treatment as risk
conditions increase. • Review your management plan for stock affected with facial eczema. Tip Refer to DairyNZ Farmfacts: Facial eczema – zinc treatment, recipes and
dose rates (3-7) and Facial eczema – treatment and prevention (3-6).Heat stress• Look out for signs of heat stress such as panting, crowding at the water
trough, reduced time spent grazing during the day, a drop in milk production and shade seeking.• Provide shade and water sprinklers at the dairy, where possible. Reduce
walking distance during the mid-afternoon and ensure that cows have ready access to sufficient clean water. Milk earlier in the morning and later
in the afternoon. Tip Refer to DairyNZ Farmfact: Managing heat stress in dairy cows (3-15). Also see
the October 2012 DairyNZ Technical Series article ‘keeping your cows cool’ pg15-19.Lameness• Check and maintain races.• Check and treat cows, if necessary.Young stock liveweight targets• 30% mature liveweight at 6 months.• 40% mature liveweight at 9 months.Visit dairynz.co.nz/animal.

demand (e.g. culling, see pg 10).
� Monitor pasture cover and maintain quality by keeping pre-
grazing and post grazing pasture levels at recommended
levels. Keep post-grazing residuals at 3.5-4.0cm (7-8 clicks
on the rising plate meter). Any lower risks over-grazing.

Facial eczema
� Start monitoring spore counts and begin zinc treatments as
risk conditions increase.
Refer to DairyNZ Farmfacts: Facial eczema – zinc treatment,
recipes and dose rates (3-7) and Facial eczema – treatment and

Heat stress
� Look for signs of heat stress such as panting, crowding at
the water trough, reduced time spent grazing during the
day, a drop in milk production and shade seeking.
� Provide shade and water sprinklers at the dairy where
possible.
People & business � Review and update your cashflow budget.
� With your team, plan holidays, the roster and extra cover (if
needed) over the Christmas period.
� Complete performance appraisals; provide feedback, identify
areas for development and consider options for on and/or off-
farm training. Appraisal templates are available in DairyNZ’s

EFFICIENT MILKING ANIMATIONSWith milking occupying over half of the annual work hours on
the average dairy farm, a lot of research has gone into finding the
most efficient milking methods in both herringbones and rotaries.
Applying these time-saving milking techniques is now easier than
ever, with online animations showing exactly how the concepts
work in practice. Check them out at dairynz.co.nz/milking.

Saving time and money when milkingMilksmart is coming to Masterton in March as part of DairyNZ’s national series of Milksmart events for 2016 focusing on milking efficiency.
Milksmart is an ideal opportunity to take home specific
answers to milking efficiency issues according to Wairarapa
dairy farmer and part time farming consultant Aidan Bichan.
“You can choose the topics you’re interested in – you don’t
have to go to everything. With access to the experts you have
the chance to drill into your own farm issues and very often
come away with an immediate fix,” says Aidan.
Aidan is a part owner of a 900-cow dairy farm and has
participated in Milksmart events over several years. In his dairy
farming consultancy business he has seen many examples of
farmers attending Milksmart, putting in place relatively small
changes and achieving significant results.
“From what I’ve seen, it’s not uncommon for farmers to find
ways to knock two to three minutes off per row or rotation.
Add that up and you’re talking 20, 30 or even 40 minutes
saved per milking. That’s a lot!
“Different people make use of that extra time in different
ways. There are of course also cost savings from running your
plant for less time by using less power, but for the people
working on the farm, finishing earlier at the end of the day
is a massive benefit. On our farm we have a target that most
people finish by 5pm, and we usually achieve that because of
milking efficiency.
Some of the solutions Aidan has seen making an impact on
time saved include optimising platform speed, refining milking
technique, improving cow flow along the race or from yard
to bail through solving lighting issues, changing the angle of
gates, changing breast rail height and changing right angle
corners to gentle sweeping bends.
“Milksmart allows you to identify areas where you can
capture savings and gives you some options and potential
solutions. Many of the changes you can make yourself without
a lot of cost and apply straight away for immediate benefit.”
Milksmart 2016 “Find another hour, save another
dollar” will be held in Masterton on March 10 and
at seven other locations around the country during
February and March. There will be sessions relevant for
all experience levels. Some of the topics to be covered
include milking frequency, cow flow, udder health,
milking efficiency, milking skills and stockmanship.
Milksmart is free to DairyNZ levy-paying farmers and
their staff and lunch is provided. Registration is essential
and will open on December 1.

NORTHLANDNorthland’s Dairy Connect service received a new
coordinator recently. Sue Rhynd, a dairy farmer at Tangiteroria
hopes to help boost Dairy Connect’s presence in Northland.
Dairy Connect creates a link for farmers who are looking
to find support and information, putting them in touch with
another farmer who has experience in working through
similar issues. Sue sees a lot of value in sharing ideas
amongst farmers, particularly those who have been through
a similar situation or change.

BAY OF PLENTYA field day in Whakatane on December 3 will cover tactics
for the summer season.
DairyNZ senior economist Matt Newman will lead a
discussion about the breakeven milk price and how this has
been affected by the past season. The field day will also
cover ‘plan B alternatives for summer’ and focus on how
two different farmers have responded to the challenges
this season has posed. The Tactics field day kicks off at
10.30am. For more information contact DairyNZ consulting
officer Wilma Foster on 021 225 8345.
SOUTH WAIKATO Farmers will get to see award winning pastures at Pasture
Renewal Persistence Competition field days in December.
The field days provide farmers with an opportunity to see
some of the best pasture growing practices in the region
and gain tips from the winners.
There are two categories: pasture sown this year (from
January 2015) and pasture renewal from more than three
winters ago (prior to May 2012).
These events will be held between December 11-17. For
more details visit dairynz.co.nz/events.
NORTH WAIKATOFarmers in the Matamata Piako District Council area are
invited to sign up to a farmer-led initiative called Matamata
Piako Three Rivers Trust. The initiative aims to build farm
profitability, improve environmental sustainability and lift
team performance. All farmers are welcome, from contract
milkers through to farm owners. The programme will
provide individual mentoring and consultancy for business
owners along with specialist group days over three years.
While farmers are asked to make a monetary contribution,
the greatest cost of the programme is covered by DairyNZ
and other key supporting organisations. For more

1. Tips to build up feed
Early summer nitrogen• At a research trial in Hamilton in 1997, applying nitrogen (two dressings of up to 50kg N/ha) during early summer (December/January) stimulated the development and growth of new ryegrass tillers.• An 8:1kg DM response per kg of nitrogen (N) was obtained in the trial with an additional 66kg MS/ha. This practice could currently generate profit of $130/ha @ $4.60/kg MS.
• Use Agrotain coated urea to help stop summer conditions degrading the N. This should allow lower rates of N to be used• Start applications early enough to avoid major moisture deficits (i.e. late November).
Early summer rotation length• Increase rotation length towards 30 days while there is still sufficient pasture cover to avoid reductions in production. Ryegrass leaf emergence rates slow as soil moisture reduces and temperatures increase which means the plants need more time between grazings to recover and generate new leaves.
To increase rotation length• Twice a week, from late November, change the normal grazing order so that the longest (or largest) paddocks in the rotation are left to accumulate some extra growth for two days. Return to graze these paddocks after two days, using the additional area and length, to get an extra grazing for the herd. By doing this there is potential to gain an extra six days between grazings in the rotation over the next 30 days.
• In a dry summer, where nitrogen has been applied, there is little gain from trying to create a rotation length longer than 30-36 days. New leaf emergence rates are 10-12 days.

2. Tips for establishing summer cropsPlan how the crop will be fed and likely grazing and re-grassing dates before sowing to ensure the crop selected fits your system. See Feeding Summer Crops on page 5.
• Green feed maize, sudan and sorghum are crops that can be established in November and early December. Sudan and sorghum need high soil temperatures.• Time from sowing to grazing is 45- 55 days for greenfeed maize (though longer will achieve higher yields), and 35-45 days for sorghum or sudan forages.
• Summer crop options such as turnips or chicory are limited past early November.• For turnips and chicory crops already established, apply N and invest in weed control.
Crop area required to feed 100 cows
3. Tips for feed
Winter feed• It’s important that during a dry period, supplements required to get through the next winter aren’t used. Ensure this is marked in some way (e.g. spray paint a line on the silage stack, ring fence or mark bales with spray paint).
When it rains• Up to 50 percent of pasture DM will disappear once it rains (rots). Allow at least 100kg DM/cow of supplement (2-3 weeks feed) for this period. On very dry farms up to 160kg DM/cow will be required post rain. After rain, ensure rotation length is held (not sped up).To work out how much feed you have on hand for summer, complete the table on page 6.

Voluntary cull cow number Cull cow number =10
4. Tips for destocking
Reducing cow numbers to 80-85% of peak numbers as soon as possible reduces the amount of feed being used on the farm for maintenance, and can divert more feed into the cows remaining on the farm. It’s a myth that empty cows milk better then pregnant cows. Research with twin cows in New Zealand shows that empty cows did not milk better than their pregnant twin until 250 days of lactation and the differences were small.Check how to use Breeding Worth (BW) and Production Worth (PW) for culling decisions at dairynz.co.nz/indicies.
*e.g. for PSM 15 October + 12 weeks total mating is 7th January + 5 weeks minimum before PD = 11th Feb, 11 weeks mating = 4th Feb and 10 weeks mating = 28th Jan; allowing all empties to be culled by end of January.
Once-a-day (OAD) milking• Somatic cell count (SCC) typically doubles when cows are switched to OAD. • Staggering the herd’s transition to OAD milking over a few days can help prevent a big spike in SCC.
• Cows milked OAD during mid/late lactation are approximately a quarter body condition score more at dry off compared with those milked twice-a-day.• BCS improvement takes time, it’s not until about six weeks of OAD milking that BCS differences are detectable. • Milk production drops by approximately 10% when cows are milked OAD post-Christmas.
• In order to gain BCS benefits, and prevent large drops in milk production don’t underfeed cows while they are on OAD milking. There is only a small decrease in feed intake (approx. 3%), when cows are milked OAD.• Farmers recommend switching to OAD while feed is still plentiful (4-5 days of feed ahead or supplements available).
Irrigation restrictionsAim to continue irrigating the most productive part of the farm well, rather than poorly irrigate the whole farm. Monitor soil moisture deficits, forecast rainfall etc. Heat stress
Be mindful of heat stress. Visit dairynz.co.nz/heatstress for information on how to prevent heat stress. There is also a calculator helping you determine when cows are most at risk.
