The Ranking of Active Sires (RAS) tool - a top-ranking tool for top-ranking sires!

The RAS list is published by NZ Animal Evaluation, an independent animal evaluation body that works alongside breeding companies to achieve greater genetic gains. NZ Animal Evaluation aims to achieve world-leading genetic gain for New Zealand dairy farmers and our national dairy herd. It utilises the best breeding traits to help farmers make informed breeding decisions for improved profitability and enhanced sustainability on their farms.
