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.

Ten adult Corriedale sheep were evaluated for respiratory (ER) and cutaneous (EC) evaporation rates. The animals were observed about 10 times each by recording changes in their live weigth with high-sensitiviy strain gauges, under different conditions of air temperature (21.1 to 41.9ºC) and partial vapour pressure (1.53 to 3.01 kPa). Average evaporation rates were 0.7599±0.0094 g.h-1.kg-1 for ER and 1.3029±0.0591 g.h-1.kg-1 for EC. Cutaneous evaporation was considered as an important heat loss mechanism for sheep in hot environments. There were […]
