The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

Three different models including or not the direct and maternal non-additive effects and the fixed effects of contemporary group, parity order, direct and maternal heterosis and the direct and maternal additive genetic random effects were compared for predicting breeding values for pre-weaning daily gain in a composite cattle population in tropical climate. The analyses were done in two stages: firstly, breed and individual and maternal heterosis effects were estimated and after variances and the heritability were obtained for prediction of […]
