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 objective of this study was to reduce the level of the biological marker Cr2O3 in animal diets, due to the sensibility of the sdiphenylcarbazide spectrophotometric method for chromium determination in feces, recently developed. Six levels of marker, chromium (III) oxide (0.01% – 0.02% – 0.03% – 0.05% – 0.1% and 0.2%), were incorporated into isoproteic and isoenergetic diets, for the apparent digestibility assay of the “piauçu” (Leporinus macrocephalus), in a design of entirely randomized groups. Feces were collected during […]

The objective of this study was to induce spawning in pirapitinga-do-sul, Brycon opalinus, with the application of hormones and to determine the pattern of oocyte diameter frequency distribution in females prepared to induction. One hundred and twenty spawners with 25.5 to 32.0 cm of length were placed in circular ponds of 10 m of diameter, at Estação de Aqüicultura de Paraibuna-SP of CESP. In order to determine the females apt to reproduction, samples of oocytes were obtained with plastic catheter […]

The experiment was carried out, during 100 days, to study different crude protein sources and levels of diets for pacu fingerlings. Two hundred and fifty two pacu fingerlings were assigned to 36 aquariums, containing seven fishes, with 150 liters of water. During the experimental period, the average temperature of the water was 28oC and other limnology parameters (dissolved oxygen, pH, alkalinity and conductivity) remainded within the levels adopted for the good development of this specie. The experimental design consisted of […]
