Data that is collected across the country is collated to deliver quality genetic estimations for dairy sires and cows.

-
All About BW
Breeding Worth (BW) is the index used to rank cows and bulls based on how efficiently they convert feed into profit.
-
Breeding Values
Breeding Values (BV) are an estimate of a cow or bull's genetic merit for a trait.
-
Economic Values
Economic values (EV's) are an estimate of the value of a trait to a NZ dairy farmer.
-
Genetic Base Cow
BW and BV are presented as the difference between an animal’s genetic merit and the ‘genetic base cow’.
-
Reliability
For all traits, reliability indicates the confidence that an animal’s BW or individual breeding values are a measure of their true merit.
-
International dairy sires
Breeding values for international dairy sires are generated by Interbull, an international genetic evaluation organisation.
-
What is inbreeding?
Inbreeding refers to the proportion of an animal's DNA that is identical because it was inherited from a common ancestor that existed on both their mother’s and father's sides of the pedigree.
-
Minimum contemporary groups
A contemporary group is a group of dairy animals that are the same age and have had an equal opportunity to perform.
