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.

With the aim of a better understanding of quantitative growth traits in Nellore cattle, some parameters were estimated: variance components and heritability coefficients of weight gains between the standardized ages of 120 and 240, 240 and 365, 365 and 455, and 455 and 555 days, and of scrotal circumference gains between the standardized ages of 365 and 455, and 455 and 555 days; and (co)variance components and genetic correlations between weight and scrotal circumference gains. Information from 29,769 records of […]
