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 fermentative characteristics and the chemical composition of elephant grass silages with increasing levels of dehydrated passionfruit by-product (DPB) were evaluated. Five DPB addition levels (0.0; 3.5; 7.0; 10.5; and 14.0%; in a grass fresh matter basis), in a complete randomized design with four replicates were studied. The grass was cut at 60 days of age, chopped, and ensiled, reaching a packing density of 600 kg/m3. After 28 days of ensiling, the silos were opened and samples were collected for […]

The microbial efficiency synthesis, the abomasum nitrogen compounds flow, the nitrogen compounds balance, the passage rate of ruminal digest, the ruminal ammonia concentration and ruminal pH in cattle fed diets containing Tifton 85 bermudagrass hay with different regrowth ages were evaluated. Four rumen and abomasum fistulated zebu cattle with average 340 kg LW were allotted in a 4×4 Latin square. All diets contained 60:40 forage to concentrate ratio. The forage was consisted in Tifton 85 bermudagrass hay with 28, 35, […]
