Abstract
A simple extension of efficient methods for utilizing relationships among dairy cattle sires in their evaluation by best linear unbiased prediction can be used for evaluation of multiple traits. The method is illustrated by defining 1st and 2nd lactation records as 2 different traits. Computations are similar to those used in Cornell''s [Cornell University, Ithaca, New York, USA] Northeast AI [artificial insemination] Sire Comparison method.This publication has 5 references indexed in Scilit:
