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 […]
