Abstract


An eight-week feeding trial was conducted to investigate the effect of feeding yam and irish potato peel meals on the growth performance and economic analysis of cross-bred (Dutch x New Zealand white) growing rabbits aged between five to seven weeks. Thirty rabbits were randomly allocated to six dietary treatments with five rabbits per treatment. Diets  1, 2, 3, 4, 5 and 6 contained 100% maize, 50% maize and 50% yam peel meal, 50% maize and 50% irish potato peel meal, 50% yam peel meal and 50% irish potato peel meal, 100% yam peel meal and 100% irish potato peel meal, respectively. The response showed that the growth parameters were not significantly (P>0.05) different among the treatment groups except mean final body weight which was significantly (P>0.05) different. The mean final body weight of rabbits fed T3 diet (50% maize and 50% irish potato peel meal) was significantly (P< 0.05) higher than those fed T2 (50% maize and 50% yam peel meal) and T6 (100% irish potato peel meal) diets, but were similar (P>0.05) to other diets.  However, the lowest mean final body weight was obtained in rabbits fed T6 (100% irish potato peel meal) diet. The cost per kg feed decreased progressively as the levels of yam and irish potato peel meals increased in the diets. The cost per kg gain also declined from  N 249.59 in T1 (100% maize) to N 181.95 in T4 (50% yam peel meal and 50% irish potato peel meal), which showed the best cost per kg weight gain. The study demonstrated that the yam and irish potato peel meals can replace maize up to 100% as energy source for growing rabbits without adverse effect on performance.
