An experiment was conducted to determine the performance of 3 mos. old post-weaning calves subjected to 4 dietary treatments. The treatments were: 1. ad libitum feeding of calf starter ration containing 20 percent protein; 2. ad libitum feeding of urea-based dairy ration (16 percent protein); 3. restricted feeding of 1.5 kg calf starter and; 4. restricted feeding of 1.5 kg dairy ration. The calf starter ration was made up of palm kernel cake (10 percent) maize (55.5 percent) cassava chips (5 percent) soybean meal (15 percent) fish meal (12 percent) di calcium phosphate (1 percent) salt (1 percent) and mineral premix (0.5 percent). The dairy ration composed of palm kernel cake (solvent extracted 25 percent) palm kernel cake (expeller pressed 25 percent) maize (20 percent) cassava chips (15 percent) rice bran (11 percent) urea (1.5 percent) di calcium phosphate (1 percent) salt (1 percent) and mineral premix (0.5 percent). The calves in each treatment group were given their respective concentrate ration plus fodder provided ad libitum. Calves given ad libitum calf starter (ration 1) gained more than those calves given ad libitum diary ration (ration 2) restricted calf starter (ration 3) or restricted dairy ration (ration 4). The calves on ration 1 incurred the highest cost of feeds per day and per kg of gain. The next highest daily gain was by calves fed 1.5 kg calf starter (ration 3). Since the costs of feed per day was not significantly different among the 3 treatments it can be concluded that restricted feeding of calf starter was more suitable for post weaning calves. The experiment indicated that post weaning calves of 3-6 mos. of age performed better with a 20 percent protein starter ration compared to the adult ration of urea based 16 percent protein dairy ration

Abstract

An experiment was conducted to determine the performance of 3 mos. old post-weaning calves subjected to 4 dietary treatments. The treatments were: 1. ad libitum feeding of calf starter ration containing 20 percent protein; 2. ad libitum feeding of urea-based dairy ration (16 percent protein); 3. restricted feeding of 1.5 kg calf starter and; 4. restricted feeding of 1.5 kg dairy ration. The calf starter ration was made up of palm kernel cake (10 percent) maize (55.5 percent) cassava chips (5 percent) soybean meal (15 percent) fish meal (12 percent) di calcium phosphate (1 percent) salt (1 percent) and mineral premix (0.5 percent). The dairy ration composed of palm kernel cake (solvent extracted 25 percent) palm kernel cake (expeller pressed 25 percent) maize (20 percent) cassava chips (15 percent) rice bran (11 percent) urea (1.5 percent) di calcium phosphate (1 percent) salt (1 percent) and mineral premix (0.5 percent). The calves in each treatment group were given their respective concentrate ration plus fodder provided ad libitum. Calves given ad libitum calf starter (ration 1) gained more than those calves given ad libitum diary ration (ration 2) restricted calf starter (ration 3) or restricted dairy ration (ration 4). The calves on ration 1 incurred the highest cost of feeds per day and per kg of gain. The next highest daily gain was by calves fed 1.5 kg calf starter (ration 3). Since the costs of feed per day was not significantly different among the 3 treatments it can be concluded that restricted feeding of calf starter was more suitable for post weaning calves. The experiment indicated that post weaning calves of 3-6 mos. of age performed better with a 20 percent protein starter ration compared to the adult ration of urea based 16 percent protein dairy ration
