MOST PROBABLE PRODUCING ABILITY (MPPA) – An estimate of a cow’s future productivity for a trait (such as progeny weaning ratio) based on her past productivity. For example, a cow’s MPPA for weaning ratio is calculated from the cow’s average progeny weaning ratio, the number of her progeny with weaning record, and the repeatability of weaning weight.

CALVING INTERVAL – The amount of time (days or months) between the birth of a calf and the birth of a subsequent calf, both from the same cow. *Calving interval of 368 or less is assigned to Donor females that are 6 years old and older. **Calving Interval of 376 to 397 is assigned to Donor Females that are 5 years old and younger.
RATIO CHANGE 6
+15 or more +7 thru +14 0 thru +6 -1 thru -7 -8 thru -14 -15 or less
RATIO CHANGE – The difference between the birth weight ratio within a known population to the weaning weight ratio within the same population of individuals. Ratio change for this measure is the difference between the cows actual average birth ratio of all her calves and the weaning ratio of all her calves.

AGE OF COWS – Cows can live for over 20 years, but on commercial farms the age at slaughter varies considerably. Farms with poor management, high-yielding cattle or high disease rates will slaughter their animals at a much younger age, normally after four lactations (around 5-6 years old), but sometimes after 2 or 3. Cows should be able to consistently breed and rebreed through about 8 years of age and performance should be maintained until around 12 years of age, that is when you might see a steeper decline in reproductive performance.

NATURAL CALVES – These are the calves that are conceived either by artificial insemination or natural service. These calves are carried by the dam and raised by the dam within the population of the operation. The number of natural calves is an indicator of the cow’s ability to raise a calf and rebreed within their environment over a longer period.
