The feeding value of three supplements to a basal grass (Pennisetum pupureum) diet was investigated using sixteen Bunaji cows. The three supplements were Pueraria phaseoloides, Leucaena leucocephala and brewers dried grain (BDG). The rate of supplementation was 30% of the daily dry matter requirement. The experimental arrangement used was a completely randomized design and euch diet was tested using four animals per diet for an experimental duration of 60 days. Parameters measured included feed intake, milk yield and composition. There was substitution effect of supplement intake on the basal grass diet intake. The intake of supplements enhanced (P<0.005) crude protein intake. The milk yields were low and values ranged from 1.1 to 2.6 kg (4% fat corrected milk/day). Supplementation increased (P<0.05) milk, fat and protein yields of the lactating cows. However, milk yields of supplemented groups were similar (P>0.05). Milk from animals fed Leucaena and BDG supplements had the highest fat 102.2 and protein 93.12 g/d contents. Milk fat contents were normal and similar (P>0.05) among the treatments. Low milk protein contents were recorded except for BDG supplement. It was concluded that the feeding of forage legumes enhanced milk production in lactating Bunaji cows.
