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.

Three blood constituents in eight crossbred Saanen goats bred in two systems ¾ pasture (S1) and semi-confinement (S2) ¾ were analyzed. The animals were fed two different diets: 30% of the dairy requirements of net energy supplied by concentrate during all the lactation (R1), and 60% of the requirements from 3rd to 13th week of lactation and 15% from 14th until the end of lactation (R2). Blood samples were taken to evaluate glucose (Gl), hemoglobin (Hb), and hematocrit (Ht) levels. The results showed that none of these traits were affected by the feeding systems. Animals in the S1 production system presented higher values of Hb (7,60 g/100 mL) and Ht (22,42%) than those of S2 animals (Hb = 6,05 g/100 mL and Ht = 17,71%). No significant difference was observed between the two production systems for Gl.
