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 study was carried out to evaluate the effect of the use of supplementation in pasture cultivated with Avena strigosa (black oats), Lolium multiflorum (ryegrass) and Vicia sativa L. (common vetch) on the composition and somatic cells count (SCC) of Jersey cow milk. Eight cows of the Jersey breed were separated by milk production, lactation period and live weight and were randomly blocked into two homogeneous groups (one with supplementation and other only on pasture), in a randomized complete design. […]

The effect of months of year upon milk production and quality was estimated through evaluation of ten dairy production units classified as specialized (S), partially specialized (PS) and not specialized (NS), which were visited on 11 months of the year. Bulk tank milk was sampled to determinate physical and chemical characteristics and somatic cell count (SCC), mastitis percentage and milk production (liters/cow/day). Besides that, samples of feeds and water used for drinking and cleaning were collected. There were not significant […]
