The Nordic Total Merit (NTM) is a complete breeding goal including both production and functional traits. Its development is the story of our commitment to a more integrated and sustainable cattle breeding. From late 1970’s, the three Nordic cooperatives that eventually merged to form VikingGenetics started to implement methods to ensure the balanced breeding goal.
Nordic Total Merit NTM – a powerful tool for dairy farmers
How to read NTM and breeding values for traits in NTM?
• Increased profit by optimal inclusion of all economically important traits.
• Balanced breeding goal for improved health, fertility, production and functional conformation.
• Based on valuable and unique registrations by farmers, A.I. technicians, veterinarians, hoof trimmers, milk labs and slaughter houses collected into the same database.
The Nordic Total Merit (NTM) is the most complete breeding index around the world; it has more than 60 sub-traits combined into 14 main traits that aim for healthy, fertile, well producing and long-lasting cows with good conformation.
The Nordic countries were pioneers of using fertility and health traits in cattle breeding. Making the breeding decisions based on NTM gives progress in all important traits and improves profit.
NTM is easy to get for all sires – regardless of origin on the basis of the international comparison of dairy bulls from Interbull. You can also get genomic breeding values for females based on NTM scale by making a genomic test.

• Breeding values are estimated by the independent scientific breeding institute NAV (Nordic Cattle Genetic Evaluation)
• Rolling base, cows 3-5 years old (for each genetic evaluation use a new group of cows)
• Average 0 for NTM, average 100 for breeding values• Standard deviation 10 units
How are the indexes in NTM expressed?Estimated breeding values (EBVs) of all animals are adjusted in such a way that animals in the base population have an average index of 100. For all traits a rolling base consisting of cows from Denmark,
Sweden and Finland that are 3-5 years of age at the date of publication is applied. That means that a new group of cows that satisfy the condition is used for each genomic evaluation. The Standard Deviation is a statistic that tells you how widely spread from the average the scores of all bulls are for any particular trait. The bell curve shows what each standard deviation represents. One standard deviation (10 units) away from the mean in either direction (the light blue area) accounts for about 68 % of the bulls. This means that bulls with NTM over 20 and breeding values over 120 represent the top 2.5% of the breed.

Weights on health, production and conformation in NTM
NTM gives progress for all traits of economic importance
Several trait groups are weighted together based on economic values that is the result of thorough economic calculations and national breed association’s expectations to future production conditions and price relations.

Today more than 50% of the weight in NTM is on health traits; 30% on production and around 20% on conformation. An increasing weight on health traits in NTM over years is a big success due to greater awareness of cost in dairy production. Dairymen manage to have less cost per kg produced milk and healthy cows will not take more attention than necessary and give the highest profit.

With NTM you are breeding for improved profit. Results show that selecting for high NTM gives progress in all traits included in NTM. Figure below shows average increase in selected traits when increasing NTM with one unit. For instance, for Holstein longevity is increased with around 0.6 index units when NTM is increased with one unit.

Correlations tell you how much progress is expected in each sub-index when making breeding selection according to NTM. For example, a correlation of 0,7 between NTM and a sub-index indicates that 70 % out of the maximum progress is expected to be achieved for that sub-index by breeding for NTM rather than breeding only for the sub-index. By breeding for NTM progress can be achieved for many traits simultaneously.

Cost cutting cow and unique health traits
Great trust in genomic breeding values and genetic progress
It is important to realize that reducing costs, such as reduced veterinary assistance because of healthier cows, is equally important in improving profitability as increasing milk yield is. They both have an effect on the profit of the dairy farmer.

Despite the fact that health traits have a negative correlation to production, all our unique health traits have a strong positive correlation to NTM, longevity and daughter fertility. That means that healthy cows live longer and have higher lifetime production.
Until 1994 no other countries in the world used health traits in cattle breeding.
We are pioneers in breeding for health and have a comprehensive health profile based on reliable registration system.

We are committed to breeding cost cutting cows!
Genomic selection has changed breeding. In the Nordic countries, the use of young sires with breeding values based only on genomic information has increased rapidly during the recent years. This is because farmers and VikingGenetics believe in genomic breeding values and act accordingly.
Farmers use genomic information as a managementtool to select females within the herd. When farmers inseminate the high NTM females with sexed semen and the low NTM females - with beef semen, the average NTM in the herd will increase. This gives cows that are more profitable.
There is genetic progress for NTM for all breeds. This implies that the average genetic capacity of the animals is improved year by year, so that in average offspring has an improved genetic level compared to the parent generation.
Figure 1 Genetic progress in NTM
Genetic progress in NTM-units per year: • Holstein (5.4) • Red Dairy Cattle (4.3) • Jersey (3.3)
With the use of genomic breeding values, the genetic progress will go faster. This makes it even more important to move in the right direction, thus have a breeding goal that contributes to economically profitable and healthy, long-lasting cows!

Economic value of NTM
Economic values of each trait in the Nordic Total Merit (NTM) are based on Nordic production circumstances as well as market prices, using advanced calculation models; it is the cow’s total revenue due to genetics expressed in Euro. The total revenue comes from the production of milk and beef, subtracted costs for labor, treatments, insemination, etc. For Holstein, 1 NTM unit has a value of 10 Euro per cow and year under Nordic conditions.
The economic value of NTM is not the same for Red Dairy Breed and Jersey as it is for Holstein due to differences in genetic variation and economic marginal revenue for all traits in NTM.
Even though the exact economic value of 1 NTM unit varies among the countries due to the difference in production conditions and prices, NTM will always be the reliable way to select the most profitable cows not only in the Nordic countries. Dairy and beef farmers all over the world can rely on NTM to achieve higher profits.

Reliable and up-to-date registration system
Registrations in the Nordic countries are the cornerstone in herd management. At the same time, they are a unique base for estimation of breeding values.
• Each cow has a unique ID from birth to slaughter• All data in ONE database• Strict veterinary rules - ALL veterinary treatments are
registered• More than 90% of herds participate in herd and
health data recording – 900,000 cows
One unique cattle database In the Nordic countries, we have a unique and complete cattle database. We get registrations from many different players, such as farmers, veterinarians, milk lab, A.I. technicians, hoof trimmers, slaughter houses, classifiers, etc. All the data are sent to the same database.

Breeding values with high reliabilityThe Nordic countries have been pioneers when it comes to breeding for health traits. We have had a well-organized registration systems for 50 years. In the Nordic countries all treatments on a cow are registered and made by a veterinarian. These data are the foundation of the breeding values for health traits. It is crucial to use direct traits – actual disease cases, and not only rely on indirect traits (such as SCC (somatic cell score) or udder conformation) - for mastitis resistance. This makes selection for disease resistance more reliable and selection for better longevity more efficient.

Production index
Growth index
Production index describes the bull’s daughters’ genetic potential for milk, fat and protein production. The index includes breeding values for• Kg milk (in the first three lactations)• Kg fat (in the first three lactations)• Kg protein (in the first three lactations)
We also have breeding values for:• fat percentage • protein percentage• persistency (bull’s daughters’ genetic potential for a
persistent lactation curve from 100 to 300 days after calving, a higher breeding value indicates flatter lactation curve)
Data: High reliability of breeding values for Produc-tion with 95% of commercial dairy herds in Denmark, Sweden and Finland participating in milk recording. Formula for calculating production index milk x (-0.20) + fat x (0.40) + protein x (0.80) (Viking-
Holstein, VikingRed)milk x (-0.30) + fat x (0.50) + protein x (0.80) (Viking-Jersey)
We breed for high fat and protein components, there-fore, there is a negative weight on kilograms of milk.
Growth index describes the genetic potential for carcass gain and carcass conformation score. The index includes breeding values for:• Daily carcass gain • Short fattening period• Long fattening period• Carcass conformation score (performed according
to Beef carcass classification system - EUROP classification)
We also have breeding values for carcass fat score.
Data: Data are registered by slaughter houses. Because of the unique ID we get carcass classification on each male offspring of our bulls. Depending on the price for meat it is an index that is important to take into consideration. Therefore, it has a weight in NTM.

For example, a Holstein bull with +120 in Kg milk sub-index has genetic potential to increase Kg milk by 6.4% compared to the average for Holstein breed, which equals to 656 kg milk extra in Viking countries.
Udder health index describes the bull’s daughters’ genetic ability to resist mastitis. Udder health index includes breeding values for udder health in the first three lactations based on records on clinical mastitis made by veterinarians. Only first case of clinical mastitis within each of four defined periods are used.
Udder health includes:• Mastitis in 1st lactation early (15 days before calving
– 50 days after calving)• Mastitis in 1st lactation late (51-300 days after cal-
ving)• Mastitis in 2nd lactation and mastitis in 3rd lactation
Cell count (first three lactations) and udder conformation (fore udder attachment and udder depth from the 1st lactation) are used as indicator traits for udder health.
Data: Udder health index is calculated based on re-cords on clinical mastitis made by veterinarians in the first three lactations.
Using data on Somatic cell count (SCC) alone is not a good enough predictor for improving mastitis resistan-ce. Correlation SCC and clinical mastitis ranges from 0.45 to 0.70. Thus, registrations of clinical mastitis are more efficient. Official registrations are done for all cows on all farms in Denmark, Sweden and Finland.
That results in a high reliability of breeding values for udder health.

Youngstock survival
Youngstock survival index (YSS) is the newest trait in NTM, added since 2016. YSS describes survival of heifer calves from day 1 after birth to 15 months of age and bull calves from birth to 6 months of age when the bull is the sire of the calf.
Youngstock survival index includes the breeding values for:• Early rearing period (heifers), 1-30 days• Late rearing period (heifers), 31-458 days• Early rearing period (bulls), 1-30 days• Late rearing period (bulls), 31-184 days
Survival traits in NTM (calving direct, longevity and newly added YSS) have high economic importance and cover the whole life-time of animals. In order to improve survival of animals during rearing period selection for more liveborn calves (relying on calving traits) and long-lasting cows (breeding for longevity) is not enough. It is more efficient to breed directly for higher survival rates among calves and young stock. By adding YSS, NTM now covers survival during the whole life-time of animals.
Data: Breeding values for youngstock survival is based on farmer registrations of all transfers/deaths of ani-mals
The table below shows average survival rate (%) across three countries for the period 2008-2012 and value in euro for improving youngstock survival by 1% unit per cow per year. Multiplying the values in euro with 100 gives a rough estimate of the value of one lost animal in each of the periods. For example, value of one calf for Holstein heifer for late rearing period is equal to around 405 euro.

There are large differences in survival between pro-geny groups of best and poorest AI bulls. This means that it is possible to breed for better survival. In the table below is an example of two bulls. The calves of the bull with 124 YSS have survived much better than the calves of the bull with 76 YSS.

For example, a dairy farm with 200 heifers (aged 1 month – 15 months) would save 2,600 EURO per year by using the bull with EBV 120 (cost of lost animals – 1,700 EURO) compared with the bull with EBV 80 (cost of lost animals – 4,300 EURO).
A bull with 120 EBV would improve youngstock survival and help farmers reduce costs by 60%, relative to a bull with EBV 80.

Daughter fertility
Daughter fertility index describes the bull’s daughters’ genetic potential to start or resume heat cycle after calving, to show oestrus and to conceive at inseminati-on. The higher the breeding values, the better fertility. Traits included in the combined index for daughter fertility index are:• Days from calving to first insemination (cows)• Days from first to last insemination (cows, heifers)• Number of inseminations per pregnancy (cows,
heifers)
We also have breeding values for: • Conception rate (heifers, cows) – bull’s daughters’
genetic potential for pregnancy success after each insemination as heifers/cows
• Heat strength (heifers, cows) – bull’s daughters gene-tic potential for showing heat as heifers/cows (based on farmers assessment on scale 1-5, data only from Sweden)
Data: Daughter fertility index is calculated based on data from insemination records on heifers and cows from first three lactations. Data is collected by A.I. technicians and farmers.
The strongest correlation between daughter fertility index and the sub-traits are for ‘Days from first to last insemination’ (0.96 -0.97) and ‘Number of inseminati-on per pregnancy’ (0.85-0.91).
High reliability of breeding values for daughter ferti-lity with 90% of commercial dairy herds in Denmark, Sweden and Finland participating in data recording.
Effect of +10 index units for daughter fertility sub-traitsThe table shows average for different breeds in Denmark, Sweden and Finland (which corresponds to the level for a bull with breeding values for daughter fertility sub-traits 100) and the effect of +10 units and +20 units in the sire on performance on the different sub-traits in daughter fertility index. Negative values mean decrease in days and number of inseminations per pregnancy and, therefore, are desirable.

Calving direct
Calving direct index describes the bull’s offspring’s ge-netic potential to be born easily and alive. Pure direct effect – the bull is father of the calf and the measure describes his direct effect on the calf’s ability to be born easily. The higher the breeding value, the more likely bull’s offspring is born easily and alive.
Calving direct index includes • Survival (direct) for the first five lactations (bull’s
offspring genetic potential to be born alive and to survive over the first 24 hours after birth)
• Calving ease (direct) for the first five lactations (bull’s offspring’s genetic potential to be born without calving problems)
We also have breeding values for: • Size (direct) (bull’s offspring’s genetic potential for
size at birth. Assessment on scale 1-4, data only from Denmark.
• 1st lactation • 2nd and later lactations
Data: Registrations for calving direct are collected by farmers. High reliability of breeding values for calving direct with 90% of commercial dairy herds in Denmark, Sweden and Finland participating in data recording.

Calving maternal
Calving maternal index describes the bull’s daught-ers’ genetic potential for easy calvings and live-born calves. The higher the breeding value, the more likely bull’s daughters calve a living calf without problems. Pure maternal effect – the bull is maternal grandfat-her of the calf. Breeding value describes his effect on the calf mother’s ability to calve easily.
Calving maternal index includes • Survival (maternal) for the first five lactations - (bull’s
daughters’ genetic potential to get a liveborn calf that survives over the first 24 hours after birth)
• Calving ease (maternal) for the first five lactations (bull’s daughters’ genetic potential to calve easily)
We also have breeding values for: • Size maternal (bull’s daughters’ genetic potential
for their calves size at birth, assessment on scale 1-4, data only from Denmark)
• 1st lactation • 2nd and later lactations• Calving (mgs) (bull’s genetic potential to get offs-
pring that are both born easily and calve easily. A combination of direct and maternal effect – the bull is maternal grandfather of the calf and the measure describes his effect both on the calf’s ability to be born easily and on the calf’s mother’s ability to calve easily. Includes breeding values for survival (mgs) and calving ease (mgs) based on calving records from first five lactations)
Data: Registrations for calving direct are collected by farmers. High reliability of breeding values for cal-ving maternal with 90% of commercial dairy herds in Denmark, Sweden and Finland participating in data recording.

Average number of lactations per cow is around 2.5 in the Nordic countries. That is because it is a common practice to inseminate almost all heifers to ensure enough replacement cows, even though the animals have a genetic potential for longer life.
Frame index describes the bull’s daughters’ genetic potential for frame conformation. Higher breeding values indicates larger cows for all breeds.
Frame index includes breeding values for:• Stature• Body depth• Chest width• Dairy form• Top line• Rump width• Rump angle
Data: Breeding values are based on classification re-cords in the first three lactations made by official clas-sifiers. We have breeding values for frame. However, as frame has weight equal to 0, frame is not included in NTM for the three breeds.

Milkability
Milkability index describes the bull’s daughters’ ge-netic potential for milking speed (expressed as flow of fat + protein). The higher the breeding value, the faster the milking speed.
We also have breeding value for leakage (how easily bull’s daughters leak between milkings. The higher the breeding value, the less the leakage. Data inclu-des herd owners’ assessment on cows leakage (leaks / doesn’t leak).
Data: Registrations for milkability are collected by farmers and are based on herd owners assessment on cows’ milkability compared to other cows in the same herd on scale 1-5. Besides that, information from ele-ctronic milk recording from AMS and milking parlours is included, measured as gram of fat + protein per minute (if available this is used instead of the herd owners’ assessment).

Temperament
Temperament index describes the bull’s daughters’ genetic potential for temperament. The higher the breeding value, the better the temperament. Data: Data is based on herd owners’ assessment on cows’ temperament compared to other cows in the same herd on scale 1-5 (Finland) or 1-9 (Denmark and Sweden).

NTM works in real life
Proven by real-world data – study results from 50 Hol-stein herds with more than 7,000 cows in Denmark
Invisible power of NTM – 7,350 cows are divided into three groups based on their pedigree NTM:
Lowest 1/3 Middle 1/3 Highest 1/3
NTM 15.0
NTM3.2
Cows might look the same but NTM reveals the diffe-rence between them. Cows with the highest pedigree NTM perform BEST.
