Eight Red Sokoto (Maradi) castrated goats in their early maturity, weighing between 16 and 21 kg were used. Two sources of nitrogen (N), urea and groundnut/palm kernel cake mixture, were used at four levels of crude protein (N x 6.25), viz., 1, 5, 9 and 13 per cent, in cassava flour-based rations. These rations were then used as supplements to dry, poor quality Cynodon nlemfuensis forage (4.5 per cent CP). The results for the two sources of N indicate that linear relationship exists between absorbed N and N intake, retained N and N intake as well as between retained N and absorbed N. From these regression equations, it is estimated that at zero N-balance (or N equilibrium) the daily N intake per Wkg°. 734 was 0.74g for the mixed protein and 0.36g for the urea rations. However, the protein-fed goat and the ureafed goat required 0.35g digestible N (2.20g DCP) and 0.13g digestible N (0.81g DCP) per Wk ,°. 734 respectively for maintenance. The protein-fed goat therefore required 2.7 times as much digestible N as the urea-fed goat for N equilibrium. The digestibility, retention and indices of "biological values" were also higher, indicating better utilization of the urea-N than the protein-N contents of the rations. These goats therefore required far less protein than that normally recommended for sheep or goats in the temperate environment. |
