IN the experiment reported, the effect of feeding different levels of protein, on the performance of young growing calves on pasture, was investigated. Thirty-six calves, mainly Friesian x Bunaji Zebu crosses, of age 3 - 4 months were divided into 3 groups for the concentrate treatments used. The 3 treatments were high protein: low grain feed (HPF), medium protein: medium grain feed (MPF) and low protein: high grain feed (LPF). The dietary protein: grain levels were obtained by mixing groundnut cake (GNC) and sorghum grain, by weight, in the ratios of 75:25; 50:50; and 25:75; respectively. Calves received 1kg DM of concentrate mixture plus free access to Rhodes grass (Chloris gayana) grazing. The average daily live-weight gains of calves were 0.84, 0.75 and 0.87kg for treatments 1,2 and 3 respectively. These did not differ significantly when tested statistically. The results indicate that the lowest of the three protein levels was adequate for the calves for optimum performance in this experiment.
