PPT-Increasing the number of SNPs used in genomic evaluations of dairy cattle

Comm 301 Reasons for changes in SNP set History Single list created across breeds Poor performing SNPs removed SNP selection criteria changed Updated assembly changed SNP locations Additional QTLs as . breed composition for crossbred U.S. dairy cattle . Introduction. Traditional evaluations are on all-breed base. Pedigree breed composition (PBC) has been computed, distributed, and used to calculate heterosis since we went to the all-breed model in .
