What do cows need?

What do cows need?• Water and feeding• Space• Rest• Air• Light

Feeding

Non-dietary factors and herd performance (Bach et al., 2008)

• 47 herds with similar genetics were fed same TMR

• Milk yield varied by ±13 kg/d– Mean milk yield = 29.5 kg/d

• Non-dietary factors accounted for 56% of variation in milk yield– Age at first calving– Feeding for refusals (29.0 vs 27.5 kg/d)– Feed push-ups (29.9 vs 25 kg/d)– Stalls:cow

Bunk space

• Reduce competition• 60 cm (Lactating)

• 75-90 cm (Dry-Transition)

Water

Water• Min 2 troughs/group• 60 cm per 15-20 cows.• 60 cm/head (exit of the parlor)

Position:External wall

Is it correct ?

~1.7 kg/dmore milk foreach extra

hour

Increased resting time with greater DIM, milk yield (Bach et al., 2010)

Cows have strong behavioral need to rest …

• Cows sacrifice feeding to make up lost resting– For every 3.5 min of lost

rest, cows sacrifice 1 min of eating

• Cows spend more time waiting in alleys to lie down than eating when overstocked

• Negative effects of short periods of deprivation are cumulative

Resting: 12-14 h/d“Vitamin R”Grant, 2010

Resting time

• Minimum 12 h/d

• To promote resting time:

– Stall width – Soft surface

Air

Temperature and humidity

• The best temperature for high milk producing cows is:

5°C !!

• Thermal comfort zone is:-13°C to +27°C (23°C for high milk producing cows)

Heat stress ( 24°C + 80% RH ):

-Reduction of consumption Reduction of production

- Reduction of length and expression of heats- Reduction of conception rate and embryo survival
