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 26,389 individual test day milk yield from 825 lactations of 356 Parda Alpina goats, recorded from 1997 to 2004, were used to estimate genetic parameters and to predict breeding values for test day (PLDC) and accumulated (PAC) milk yields. The model for PLDC included the fixed effects of contemporary group (year-month of test), age of dam at kidding as covariate, and additive genetic, permanent environment and residual random effects. The model for PAC included the same random […]
