Eighteen lactating Etawah Crossbred goats with bodyweights between 15.00 to 15.75 kg. were used in this study utilizing a complete randomized design. The treatments were fresh elephant grass as the sole diet (ration Ra), elephant grass supplemented with raw-casava containing urea based concentrate (ration Rb), and elephant grass supplement with cooked-cassava (heat-moisture treated) containing urea based concentrate (ration Rc). Ration Ra, ration Rb, ration Rc respectively cause changes in the following parameters of milk: Milk production 111.44a, 119.50b and 122.19b g/animal/day. Fat content 4.89, 4.92 and 5.33 %. Protein content 3.86a, 4.24a and 4.89b %. Lactose content 2.50, 2.57 and 2.65 %. Dry matter content 14.86a, 15.43a and 17.45b %. Non-fat DM 9.97a, 10.51a and 12.07b %. Specific gravity 1.0337a, 1.0357a and 1.0419b. Except for milk production, no significant difference are found between treatments ration Ra and ration Rb on all parameters measured. Figures on a horizontal line with different superscripts (a, b) differ significantly (P0.05). Cooked-cassava, compared to raw-casava in the urea containing feed supplement significantly improves the utilization of this carbohydrate source for milk production in goats.
