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.

Fourty-eight barrows proceeding from crossing between commercial hybrids were used in a study to evaluate the different lysine levels on the performance and the carcass characteristics. The swines average initial and final weight was 110.1 ± 0.72 kg and 125.3 ± 1.23 kg, respectively. The animals were distributed in an experimental design of randomized blocks with four treatments, six replicates and two animals per replicate. The treatments corresponded to a basal diet with 13.7% of crude protein and 3367 kcal […]

This experiment was carried out to determine the best live weight to start the feed restriction (RA) in order to improve the performance and carcass quality of barrows and gilts at the finishing phase, fed with dry feed, in the winter period. Four treatments was compared: T1 – Full fed (AV) until the slaughter time, T2 – AV until 90 kg LW and after that 10% RA; T3 – AV until 75 kg LW and after that 10% RA; T4 […]
