What this tool doesn’t include

This selection tool doesn’t include traits where the ‘mid-point’ is optimal (i.e. teat placement) head over to the bull team builder to refine your team for these traits

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.

The latest Animal Evaluation run took place on 6 December 2024 (the next run is on 17 January 2025).
