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 objective of this research was to evaluate the quality of eggs from Dekalb White hens under different temperatures (room temperature, 25 ºC; and refrigeration, 8 ºC), storage times (7, 14 and 21 days), age of birds (35, 40, 45 and 50 weeks) and housing densities (625, 500, 416.6 and 357.14 cm2/birds). Haugh unit (HU) values and albumen height of 1,120 eggs from 528 laying hens, randomly allocated to four groups with different population densities were evaluated. The results showed […]

The objectives of this study were to evaluate the existence of a relationship between tiller size and tiller number in grazed palisadegrass swards and to verify if adjustments related to changing in leaf area index (LAI), leaf area:tiller volume ratio (R), and tiller bulk density in the prediction equation of the response would explain eventual slope deviation from the theoretical predict slope. Treatments corresponded to four sward “steady state” conditions (10, 20, 30, and 40 cm sward surface heights), maintained […]
