The objective of this study was to estimate direct and maternal additive genetic, non-additive and heterozygotic effects for pre and post-weaning traits and to develop equations to predict growth performance in a multi-breed Aberdeen Angus (Angus)-Nellore herd. The analyses were performed by SAS® using two different models. The model 1 (M1) was used for the pre-weaning traits, weaning weight adjusted to 205 days of age (P205) and average daily gain from birth to weaning (GMDND), and included the fixed effects […]
