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.

Dry matter intake (DMI) of Tanzania grass under grazing conditions was estimated using 24 Holstein-Zebu and Gir cows from the in vitro dry matter digestibility of extrusa samples (esophageal fistulated cows) and fecal output. The fecal output was estimated using chromium mordant and a non-linear model. The pasture was managed in a rotational system with three days paddock occupation and 39 days of resting period. The stocking rate was 2.0 cows/ha during the rainy season. Four different equations based on […]

Dry matter intake (DMI) of coastcross bermudagrass grazing by crossbred Holstein-Zebu and Zebu lactating cows was calculated using in vitro dry matter digestibility from extrusa (four esophageal fistulated cows) and fecal output estimate with mordent chromium by the non linear model. Pasture was managed in a rotational system with three days of occupation and 27 days of resting period, adopting a stocking rate of 1.6 and 3.2 cows/ha respectively during the dry and rainy season. Four different equations based on […]
