The equi-protein replacement of groundnut cake (GNC) protein with centrosema leaf protein concentrate (CLPC) was evaluated in diets for weaned rabbits. Prior for the feeding trial, the CLPC was analyzed for its chemical composition with respect to proximate composition and gross energy. Thereafter, five dietary treatments were formulated with an average crude protein content of 19.18±0.52 and average energy content of 2321.72±12.69 Kcal ME/kg. The control (diet 1) contained 27% GNC whose protein was gradually replaced at 5, 10, 15, or 20% with CLPC in diets 2, 3, 4 or 5, respectively. Thus the inclusion level of CLPC was 2.99, 5.98, 8.97 or 11.96%, in whole ration for diets 2, 3, 4 and 5, respectively. A total of thirty-five weaned rabbits with mean weight of 587.15±50.13g was randomly assigned to the five dietary treatments with seven replicates and a rabbit per replicate. The average weight gain, live-shrunk weight and feed efficiency were not significantly (p>0.05) influenced by the dietary treatments. On the carcass traits measured, only the head weight showed no significant difference (p>0.05). Other carcass traits such as neck, loin, pelt, shoulder and thigh were significantly higher (p<0.05) at inclusion level of 10%-based CLPC and above. The aforementioned carcasses increased with increase in the level of CLPC in place of GNC. The relative organ weights of the heart and pancreas were not influenced (p>0.05) by the test diets while those of liver, lung and kidney were significantly higher (p<0.05) than the control diet. The result of the cost analysis showed a decline in feed cost per kilogram from 2.60 to 10.72% as the level of CLPC increased from 2.99 to 11.96% in diets 2 to 5. The implication is that, it is most economical to raise rabbits on CLPC substituted for GNC at 11.96% CLPC supplementation.
