Breeding values provide an indication of the genetic merit of an animal for a specific trait; they are calculated using information which is collected on-farm. Cows which are routinely measured through herd testing, herd weighing and TOP assessment will have more reliable breeding values then those which are not. Similarly, the reliability of a bull’s breeding values increase as more of his daughters are measured.
There are currently seven traits included in the Breeding Worth index; these traits have been selected as they have an economic value to a New Zealand dairy farm, and they are able to be measured.
