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.

Genetic divergence among three lineages of meat-type hens from the Genetic Breeding Program of the Universidade Federal de Viçosa was evaluated for the following traits: days at first egg (DPPO), egg production rate (TP) from 22nd to 56th week, body weight on the 32nd (PMI1), on 40th (PMI2), at 48th (PMI3), at 56th (PMI4) and at the 64th week (PMI5), egg weight on the 32nd (PMO1), on 40th (PMO2), at 48th (PMO3), at 56th (PMO4) and at the 64th week […]

Fifteen intra specific hybrids and two cultivars of elephant grass were evaluated in a randomized block design with four replicates. The experiment was carried out at the Forage Production Section of LZNA/CCTA of Universidade Estadual do Norte Fluminense, Campos dos Goytacazes, RJ, from February/95 to December/97, resulting on 12 harvests. The materials were evaluated for total dry matter (DM) production, dry season production, contribution of dry season to total annual production, percentage of leaves, height (m), diameter of stem at […]
