NZAEL Genetic Base Change
As of June 26, 2010 the New Zealand Animal Evaluation system has changed its genetic base to the group of cows that were born in 2000 (from 1995 base) and that had performance records for all traits in the evaluation system in the dairy season 2002/03.
For the Breeding Worth (BW) index you can expect the reported BW for each animal to be approximately $41 lower prior to this genetic base change.
Take Note daughters are efficient cows with excellent potential for fertility and longevity. They have outstanding farmer traits and useful linear scores but are not suitable for mating over maiden heifers.
