  • This tool includes every bull enrolled with Animal Evaluation in NZ. If you can’t find a bull that you are interested in, get in touch with the marketer and let them know that you would like the bull to be enrolled. Marketers pay a fee to enrol bulls, and this is a key funding stream for NZAEL.

Parent Average Adjustment

On average, the genetic merit of young dairy bulls is typically over-estimated for production traits. To account for this over estimation in young bulls, a parent average adjustment has been applied to breeding values for fat, protein, milk volume and residual survival traits.  This adjustment comes into effect when a young bull has his AB Code allocated, and is gradually blended out as he accumulates data from herd tested daughters.
