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.

Fourteen dairy calves, four months of age were allocated in two treatments: control and supplemented with 0,4 ppm of Cr in the basal diet, which had 52% of grass hay and 48% of concentrate (corn meal and extruded soybeans) during 98 days. Feed intake was measured daily. In the last week were performed a glucose tolerance test. Performance were not affected by treatment (liveweight gain 1.330 and 1.320 kg/d; feed efficiency 0.24 and 0.25 and feed conversion, 4.13 and 4.07 for control and treated groups respectively). Chromium tended to decrease the blood glucose, but there were no statistical differences.
