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.

Data consisting of 20,065 weights of 3,016 Nellore animals recorded from birth to 630 days of age were used to compare random regression on Legendre polynomials of age (LP) and on Legendre polynomials associated to a parametric correlation structure (PC) models for breeding value prediction of growth traits. Results from Standard bivariate analyses (SBA) using weights at standard ages were also compared to those from random regression models. Dependent variables in random regression analyses were Legendre polynomials of age at […]
