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.

Restricted maximum likelihood (REML) estimates of additive and residual variances and covariances for birth weight and adjusted weights at 120, 205, 240, 365, 420 e 550 days of age were used to estimate growth covariance functions (CFs) of Tabapuã beef calves. Data were observed on 41,415 animals born from 1975 to 1997 and raised under pasture conditions. Estimation of CFs is a very useful tool to analyze beef cattle growth. It was possible to estimate covariance between any pair of […]
