The Ranking of Active Sires (RAS) is a list of top ranking dairy sires. Individual breeding companies nominate their highest quality sires, and the bulls are then ranked according to their Breeding Worth.
The quality of the bull team that you use each year is the single biggest driver of genetic improvement in your herd.
- Target high BW bulls
- Consider the traits you want to improve in your herd
- Check your team and remove any bulls that score low on those traits.
Note: Following the upgrade to NZAEL 2.0, the method used to calculate reliabilities has changed. This will result in an average drop in BW reliability of around 5%. The RAS eligibility criteria has been updated to reflect this. From February 2020, bulls must have a minimum BW reliability of 70% Previously this was 75%.
