The direct effect of Red Angus (), computed as deviation from the direct effect of Nellore (), and the effects of individual () and maternal () heterozygosity, resulting from crossing these breeds were estimated. The multiple regression method was used to analyze birth weight (PNT), weaning weight (PDS), yearling weight (P12M), and for the daily weight gain from birth to weaning time (GMD_ND) and from weaning to 12 months (GMD_DA). A total of 410 calves from the groups of Nellore, […]
