Eighteen young West African dwarf (WAD) goats were used to compare the utilization of sewage sludge, poultry droppings and groundnut cake rations by WAD goats. Total dry matter intake of the animals fed diet A (groundnut cake based ration) and C (poultry droppings based ration) was significantly (P < 0.05) higher than dry matter intake of animals fed diet R (dry activated sewage sludge based ration). Total dry matter intake of animals fed diet A (664.6 g/day) appeared to be higher than those fed diet C (600.5g/day), although the differences observed were not significant. Values observed for apparent dry matter, ether extract and nitrogen-free extract digestibilities between animals fed the different diets were not significant (P > IWS). Crude fibre and crude protein digestibility values however varied appreciably. Values recorded ( 12.03, 1.04 and 10.42 g/day; and 3.13, 0.28 and 2.72 g/day/W0.75Kg for animals fed diets A, B, and C respectively) for nitrogen balance and weight gains (56.8, -2.7 and 36.8 g/day for animals fed diets A. B and C respectively} were higher for animals fed diet A, followed byanimals fed diets C and B respectively.Keywords: Protein utilization, groundnut cake, poultry droppings, sewage sludge, WAD goats |
