Contribution of the weighted single-step GBLUP method for genomic evaluation of udder conformation in Holstein cattle
Original language description
The appropriate udder conformation in dairy cattle is associated with the economic profitability of milk production in commercial dairy farms. In this study, GEBVs for udder morphology (udder depth, rear udder height, front and rear teat placement, central ligament, fore udder attachment, teat length, and rear udder width) were predicted based on 699,681 cows‘ phenotypes for 1,772,297 Holstein individuals using the single-step genomic BLUP (ssGBLUP) and weighted single-step genomic BLUP (wssGBLUP) method. The comparison of both methods was assessed using bull validation test. Validation reliabilities and regression coefficients were comparable for all traits and both methods.
