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 experiment was conducted to evaluate dry matter (DM), crude protein (CP), and neutral detergent fiber (NDF) ruminal degradation of elephantgrass silages wilted under the sun light for eight hours or with addition of 0, 7, 14, 21, and 28% of cocoa meal (CM) at the ensiling. Samples of each silage type were incubated in the rumen of three Holstein cows for 0, 6, 12, 24, 48, 72, 96, 120, and 144 hours. The CM inclusion reduced the degradation potential […]

In situ DM and CP degradabilities of leaflets of three tropical legumes: leucaena (Leucaena leucocephala (Lam.) de Wit), pigeon pea (Cajanus cajan (L.) Millsp.), and glycine (Neonotonia wightii) and of leaves of two other tropical forages: ramie (Boehmeria nivea (L.) Gaudich) and cassava (Manihot esculenta Crantz) were determined in this trial. Three grams of pigeon pea, glycine, and ramie and 5 g of leucaena and cassava were incubated in the rumen of four steers for 3, 6, 12, 18, 24, […]

A trial was carried out to evaluate the change in digestion of tropical grasses leaf and stem tissues with age. The grasses were signalgrass (Brachiaria decumbens), molassesgrass (Melinis minutiflora) and Tifton 85 bermudagrass (Cynodon sp). The 7th leaf of signalgrass and molassesgrass and the 11th leaf of bermudagrass were sampled by the time of their complete expansion (ligule exposure) and 20 days later. Segment of stem just below the sampled leaf was also sampled. Transversal sections of leaf and stem […]
