Genomic prediction and genetic parameter estimation for unsaturated and saturated fatty acids in Canadian dairy cattle.

ABSTRACT: The current study aimed to obtain the estimates of heritabilities and genetic correlations and the prediction abilities and accuracy of Bayesian GBLUP and Bayesian alphabet (BayesA, BayesB, BayesC) models for total and individual monounsaturated, polyunsaturated and saturated fatty acids from Canadian Holstein cows by using genome-wide SNP markers from genotyping-by-sequencing method. The heritability estimates were obtained from Bayesian GBLUP and Bayesian alphabet models. They ranged from 0.61 to 0.67 for total monounsaturated, from 0.35 to 0.45 for polyunsaturated and from 0.51 to 0.60 for saturated fatty acids, respectively. For thirty-three individual monounsaturated, polyunsaturated and saturated fatty acids, the heritability estimates ranged from 0.27 to 0.69 for individual monounsa
