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 experiment was to evaluate the fermentative and chemical parameters of four different bulk densities of marandugrass (Brachiaria brizantha) silages. The forage was harvested with 60 days of vegetative growth and 32% of DM. The bulk densities used were 100, 120, 140 and 160 kg DM/m3. Treatments were distributed in a completely randomized design with four replicates. Gas production data were analyzed by repeated measures model. The lower density silages showed greater gas production. Low effluent production […]
The present trial aimed to evaluate the effects of wilting (wet vs. wilted), particle size reduction (small vs. large) and the addition of fibrolytic enzymes (alone vs. combined with Lactobacillus plantarum) on the chemical composition and effluent yield of Tanzaniagrass silages (Panicum maximum Jacq. cv. Tanzania). The forage was harvested and cut at 45-day vegetative re-growth period and stored in the experimental plastic silos (50 L) during 136 days. During the storage period, the effluent flow was collected and measured […]
An experiment was conducted using elephant grass (Pennisetum purpureum Schum.) cv. Cameroon, with the purpose of determining the quantitative and qualitative characteristics of effluent released, correlating this with levels of pressure and the quality of silage. The material with 13% of dry matter was ensiled in experimental plastic silos. The levels of pressure were: 356.67; 446.67; 531.33; 684.00 and 791.00 kg/m3. The effluent of silages with high moisture content was collected and measured during seven days. In silages with high […]
