Proof terminology explained

The letters, numbers and acronyms on a proof sheet can be complicated. Here, we break down the meaning and explanation of the proof indexes, traits and terminology.
Selection indexes

Genetic selection indexes are set by national organizations or breed associations. Genetic indexes help dairy producers focus on a total approach to genetic improvement, rather than limiting progress by single trait selection.

However, each farm is unique, with different situations and future plans. With that in mind, it’s important to understand what traits are included in each industry standard index. When you know what’s included, you can more effectively evaluate if the index truly matches your farm’s goals.

TPI = Total Performance Index
TPI is calculated by the Holstein Association USA (HA-USA) and includes the following trait weightings.

Image to show the weights on production, health and type for the TPI Index

PRODUCTION TRAITS = 46%

21% Pounds of protein
17% Pounds of fat
8% Feed efficiency

HEALTH TRAITS = 28%

13% Fertility index
-5% Somatic cell score
4% Productive life
3% Cow livability
2% Daughter calving ease
1% Daughter stillbirth

TYPE TRAITS = 26%

11% Udder composite
8% PTA type
6% Foot & leg composite
-1% Dairy form

NM$ = Net Merit Dollars

NM$ is a genetic index value calculated by the Council on Dairy Cattle Breeding (CDCB). It describes the expected lifetime profit per cow as compared to the base of the population born in 2010. Trait weightings are generally updated approximately every five years and include emphasis on the following traits. The current trait breakdown is in place as of August 2018. Please note that trait weights are rounded to the nearest percentage.

GENERAL PROOF TERMS

CDCB: Council on Dairy Cattle Breeding
Calculates production and health trait information for all breeds

MACE: Multiple-trait across country evaluation
Denotes that a bull’s proof evaluation includes daughter information from multiple countries

PTA: Predicted transmitting ability
The estimate of genetic superiority or inferiority for a given trait that an animal is predicted to transmit to its offspring. This value is based on the animal’s own records and the records of known relatives.

EFI: Effective future inbreeding
An estimate, based on pedigree, of the level of inbreeding that the progeny of a given animal will contribute in the population if mated at random

GFI: Genomic future inbreeding
Similar to EFI, an animal’s GFI als predicts the level of inbreeding he/she will contribute in the population if mated at random. Yet, GFI provides a more accurate prediction. It takes into account genomic test results and the actual genes an animal has.

aAa: an independent method for making mating decisions

DMS: a separate, independent method for making mating decisions

 

PRODUCTION TRAITS

PTAM: Predicted transmitting ability for milk

PTAP: Predicted transmitting ability for protein

PTAF: Predicted transmitting ability for fat

PRel: the percent reliability of a sire’s production proof

 

HEALTH & FERTILITY TRAITS

PL: Productive Life
Measured as the total number of additional or fewer productive months that you can expect from a bull’s daughters over their lifetime. Cows receive credit for each month of lactation, with more credit given to the first months around peak production, and less credit given for months further out in lactation. More credit is also given for older cows than for younger animals.  

LIV: Cow livability
Measure of a cow’s ability to remain alive while in the milking herd.

SCS: Somatic cell score
The log score of somatic cells per milliliter.

DPR: Daughter pregnancy rate
Daughter Pregnancy Rate is defined as the percentage of non-pregnant cows that become pregnant during each 21-day period. A DPR of ‘1.0’ implies that daughters from this bull are 1% more likely to become pregnant during that estrus cycle than a bull with an evaluation of zero. Each increase of 1% in PTA DPR equals a decrease of 4 days in PTA days open.

HCR: Heifer conception rate
A virgin heifer’s ability to conceive – defined as the percentage of inseminated heifers that become pregnant at each service. An HCR of 1.0 implies that daughters of this bull are 1% more likely to become pregnant as a heifer than daughters of a bull with an evaluation of 0.0

CCR: Cow conception rate
A lactating cow’s ability to conceive – defined as the percentage of inseminated cows that become pregnant at each service. A bull’s CCR of 1.0 implies that daughters of this bull are 1% more likely to become pregnant during that lactation than daughters of a bull with an evaluation of 0.0.

MAST: expected resistance of an animal’s offspring to clinical mastitis
Daughters of a bull with a MAST value of +1.0 are expected to have 1% fewer cases of mastitis than the average herdmate.

METR: expected resistance of an animal’s offspring to metritis
Daughters of a bull with a METR value of +1.0 are expected to have 1% fewer recorded cases of metritis than the average herdmate.

KET: expected resistance of an animal’s offspring to ketosis
Daughters of a bull with a KET value of +1.0 are expected to have 1% fewer recorded cases of ketosis than the average herdmate.

DA: expected resistance of an animal’s offspring to displaced abomasum
Daughters of a bull with a DA value of +1.0 are expected to have 1% fewer recorded cases of displaced abomasum than the average herdmate.

MFEV: expected resistance of an animal’s offspring to milk fever (hypocalcemia)
Daughters of a bull with a MFEV value of +1.0 are expected to have 1% fewer recorded cases of milk fever than the average herdmate.

RP: expected resistance of an animal’s offspring to retained placenta
Daughters of a bull with a RP value of +1.0 are expected to have 1% fewer recorded cases of retained placenta than the average herdmate.

HRel: the reliability percentage for a sire’s health traits

 

CALVING TRAITS

SCE: Sire calving ease
The percentage of bull’s calves born that are considered difficult in first lactation animals. Difficult births include those coded as a score of 3, 4 or 5 on a scale of 1-5.

DCE: Daughter calving ease
The percentage of a bull’s daughters who have difficult births during their first calving. Difficult calvings are those coded as a 3, 4 or 5 on a scale of 1-5.

SSB: Sire stillbirth
The percentage of a bull’s offspring that are born dead to first lactation animals.

DSB: Daughter stillbirth
The percentage of a bull’s daughters who give birth to a dead calf in their first lactation.

 

TYPE / CONFORMATION TRAITS

PTAT, UDC and FLC are all calculated by the Holstein Association USA.

The proof is in your numbers

Let us show you…

We can show you the proof that genetics are one of the cheapest investments you can make to improve the profitability and efficiency of your herd. Proof sheet numbers may seem unclear or unrealistic. So we break them down to see how they translate within your own herd.

When you use a herd management software program, we can create a genetic assessment of your herd to see if genetics really work on your farm.

Do your 2-year-olds give as many pounds of milk as their sires’ proofs predict? Do these cows become pregnant as quickly as their sires’ DPR numbers suggest? And do daughter stillbirth numbers prove to be accurate indicators of DOAs?

When we do a genetic assessment for your herd, it’s important to realize that we only take into account first-lactation animals in order to minimize environmental effects. Phenotype equals genetics plus environment. So when we eliminate – or at least minimize – environmental influences, the actual performance differences we see are due to genetics.

We want to show you how those proof numbers translate to more pounds of milk, more pregnancies and fewer stillborn calves. So here, we take one of our real DairyComp 305 analyses of a real 1,500-cow herd for answers.

The proof in genetics: PTA Milk (PTAM)

We start with PTAM, which tells us how many more pounds of milk a first-lactation animal will produce compared to herdmates on a 305-day ME basis. We set out to find if higher PTAM values on this farm actually convert to more pounds of milk in the tank.

In this example, we sort all first-lactation animals with a known Holstein sire ID, solely on their sires’ PTAM values. We then compare that to their actual 305-day ME milk records.

As Table 1 shows, based on genetics, we expect the top 25 percent of first-lactation heifers to produce 1,541 more pounds of milk on a 305ME basis than their lower PTAM counterparts. In reality, we see a 2,662-pound difference between the top PTAM animals and the bottom in actual daughter performance.

Table 1: How does selection for PTAM affect actual 305ME performance?
# of cowsAvg. Sire PTAMAvg. 305ME Production
Top 25% high sire PTAM178150844080
Bottom 25% low sire PTAM171-3341418
Difference15412662
This means that for every pound of milk this herd selects for, they actually get an additional 1.69 pounds of milk. So these first-lactation animals are producing well beyond their genetic potential.

Why do they get more than expected?

When we do most on-farm genetic assessments, we find that the 305ME values closely match the predicted difference based on sire PTAM. However, in this example, the production exceeds what’s expected by more than 1,100 pounds.

We often attribute that bonus milk top-level management, where genetics are allowed to express themselves. This particular herd provides a comfortable and consistent environment for all cows. All of these 2-year-olds are fed the same ration, housed in the same barn and given the same routine. At more than a 40,000-pound average 305ME, this is certainly a well-managed herd, which allows the top genetic animals to exceed their genetic production potential.

Perhaps even more importantly, the identification in this herd is more than 95 percent accurate. Without accurate identification, this analysis simply won’t work. That’s because some cows whose real sire information puts them in the bottom quartile will actually appear in the top quartile and vice-versa.
