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.

This research was conducted to compare the internal markers: indigestible neutral detergent fiber and acid detergent fiber, obtained after 144 h of in vitro (ivNDF, ivADF) and in situ (isNDF, isADF) rumen incubations; and the chromium oxide (Cr2O3) as external marker. The fecal output of dry matter and organic matter and the duodenal flow of crossbred steers, castrated and canulated in the rumen and in the duodenum. The steers were and fed with corn silage or the cassava hulls + […]

This work was carried out to evaluate the digestibility, using Cr2O3 and indigestible neutral detergent fiber (INDF), as markers, and also the degradability using ground ear corn (GEC). Six treatments were used in a factorial design, with three milling degrees (3/8″, 9/16″ and 3/4″) of ground ear corn and peanut meal or corn gluten feed as protein sources. The milling degrees of ground ear corn did not have effect on pH, N-NH3 , digestibility (dry matter – DM, crude protein […]
