  •  QTL Experiment in Brief
    Animals:10 US cattle breeds (3,570 Black Angus, 1,328 Brangus, 200 Charolais, 1,374 Gelbvieh, 2,779 Hereford, 2,239 Limousin, 1,761 Red Angus, 328 Shorthorn, 574 Maine-Anjou and 4,124 Simmental)
     Breeds associated:
    Design:Genotypes of 18,274 animals (BovineSNP50 BeadChip versions B or C or with BovineHD BeadChip) were analyzied for association with twelve traits were analyzed (birth, carcass, mature and yearling weights; weaning weight and calving ease direct and maternal; fat thickness; marbling; ribeye muscle area and yield grade).
    Analysis:all 54,555 SNP markers were simultaneously considered as predictors of the response variables to estimate marker effects in a mixture model in which non-zero SNP effects are drawn from distributions with marker specific variances and some known fraction of markers (pi) have no effect on the trait was used to estimate marker effects.
