Problem Set 6

ANSI 5303 Advanced Animal Breeding

 

We have the data from the back of this page concerning the yearling weights of calves from 3 herds and 4 sires. Assume that sires 2 and 3 are half sibs (relationship = .25). Otherwise the sires are unrelated and non-inbred. Assume a heritability of yearling weight of .40.

 

Calculate the EPDs for these sires using a sire model analysis with inclusion of the relationship matrix.
