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.

ABSTRACT The objective of this study was to determine the impact of metabolic changes occurring in induced subclinical gestation toxaemia in ewes on metabolic parameters and vigour in the first 72 h of their lambs’ life. Fifty-one adult Corriedale ewes of known gestation date and fed on a natural pasture were randomly divided into four groups at day 145 of gestation. Group A (ewes with single pregnancies) and group C (ewes with twin pregnancies) were fed on a natural pasture […]
ABSTRACT The objective of this study was to determine the effect of supplemented organic selenium at different levels to concentrate feed of Norduz ewes in late pregnancy on maternal serum, placenta, colostrum, and offspring serum concentrations. This study was conducted using two-year-old 35 Norduz ewes. Ewes were randomly assigned to one of three dietary treatments for 57 days prepartum and at the seven days postpartum. Group 1 was fed a standard pregnant sheep concentrate basal diet without any additional Se […]
The potential performance of lambs and ewes from the Suffolk breed in pasture of Tifton grass 85 (Cynodon spp.) and ryegrass (Lolium multiflorum) was evaluated in different production systems: lambs weaned with 60 days and kept in pasture; lambs with ewes and kept in pasture; lambs with ewes and kept in pasture with creep feeding; feedlot confined lambs with alfalfa hay + balanced ration. The treatments were applied when the lambs reached 60 days of age until slaughter time, at […]
The objective of this trial was to evaluate production of nursing ewes and yearling female lambs grazing annual ryegrass pasture (Lolium multiflorum Lam) supplemented or not with corn grain or soybean meal. Supplements were fed to animals in a quantity equivalent to 1% of sheep unit (ewe + lamb) body weight. The following variables were investigated: average daily gain, body weight gain per hectare, and stocking rate while for ryegrass pasture the following measurements were taken: forage mass, losses, and […]
