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.

An experiment was carried out to evaluate the influence of glutamine on the carbon turnover in the intestinal mucosa of weaned piglets. Nine matrices received diets predominantly composed by photosintetic cycle C4 plants during the gestation (d‰13C = -17.12) and lactation (d‰13C = -19.26). The piglets were weaned at 21 days of age, and 68 animals were fed rations composed by photosintetic cycle C3 plants (d‰13C = -25.12). The piglets were distributed at random in two treatments: one diet without […]
This trial was carried out to evaluate the effects of replacing soybean meal with hydrolyzed protein of the cellular content of yeast (HPCCY), isolated protein of soy (IPS), hydrolyzed protein of intestinal mucosa membrane of swine (HPIMS) and dried whole milk on intestinal mucosa membrane morphology and pancreas development of weaned pigs at 7 and 14 days post weaning. Fourty-four piglets (averaging 5.5 ± 0.6 kg) were fed the following isonutritive diets: SM – yellow corn-soybean meal based diet; DWM […]
Influence of Antinutritional Factors of Leucaena (Leucaena leucocephala and Leucaena cunningan) and Pigeous Bean (Cajanus cajan) on the Intestinal Epithelium and Performance of Broiler Chickens
A trial was conducted to evaluate the influence of antinutritional factors in some feedstuffs on broiler chick’s performance and intestinal epithelium. A total of 480 one-day old broiler chicks were allotted to a completely randomized experimental design with four treatments (A= corn and soybean meal based control diet; B = diet containing Leucaena leucocephala – 6% [LL]; C = diet containing Leucaena cunningan – 6% [LC] and D = diet containing Pigeous bean – Cajanus cajan – 20% [CC]), four […]
