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.

It was evaluated 27,523 and 21,746 records on traits of conformation, finishing precocity and musculature measured at weaning and a year after weaning, respectively, for the estimation of (co)variance components among these traits, and between them and body weights at the same ages. The data were analyzed by employing an animal model with direct and maternal genetic effect and permanent maternal environment effect. Restricted maximum likelihood was employed for the estimation of genetic parameters. The heritability estimates of visual scores […]
