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.

The objectives in this study were to compare alternative animal models for analysis of gestation period and verify if this trait has enough genetic variability to be included in selection programs, by using heritability estimates and genetic correlations with body weights at birth (BW) and at 12 months of age (W12), in a Canchim herd. Gestations of 2,889 calves, weight of 8,506 animals at birth and 6,372 animals at 12 months of age were analyzed. Gestation period was studied as […]
