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 Animal Evaluation (AE) run for November is now complete. See below for updated breeding values for AE enrolled dairy sires.
Please note: Cow AE results will be loaded onto MINDA on 18 November following the completion of LIC's genomic process.
As you are aware, we are investigating the fertility results of the November AE run.
Through the course of our investigation we have compared the change in fertility BV with the new mating and calving phenotype data that has been received for the daughters of individual bulls. This comparison has identified a number of bulls with unexplained shifts in their fertility BVs.
We are now confident that this issue is isolated to the fertility trait, and so have released a partial run, updating all traits except fertility.
We will continue to work with the fertility AE model, and will publish the updated results as soon as possible

The quality of the bull team that you use each year is the single biggest driver of genetic improvement in your herd.
- Always target high BW bulls
- Check the breeding values of the bulls in your team.
If you are interested in improving certain traits, such as fertility, then it is worth double checking your team to ensure the bulls suit your individual requirements.
The latest Animal Evaluation run took place on 17 November 2017 (the next run is on 11 December 2017). Click here to view the full AE run schedule.
