An experiment was conducted with 30 mixed bred rabbits (6 to 8 weeks old) averaging 592g to assess the performance, haematology, serum biochemistry, carcass and organ weights of growing rabbits fed graded levels of dried Moringa oleifera Leaf Meal (MOLM) of 0%, 25%, and 50%, as a replacement of Soya Bean Meal (SBM) and groundnut cake in 8-week feeding trial. Feed consumption and weight gain were monitored. Blood samples were collected from the animals through the ear vein for haematology and serum biochemistry, while weight of cut parts and visceral organs were collected from the animals after they were stunned and sacrificed after the 8-week feeding trials and weighed. Results showed that there were significant differences (p < 0.05) in the value obtained for weight gain, feed conversion ratio, total protein and White Blood Cell (WBC). While the results of carcass and organ weight showed significant (P < 0.05) difference in values obtained for live weight, dress weight spleen, head and kidney. While there was no significant difference among the blood constants (VGM and MCHC). Among the leukocyte differential counts examined, lymphocytes, monocytes and eosinophils were not significantly different among the dietary treatments. The results suggest that MOLM possess good dietary protein quality for optimal growth of rabbits and be incorporated in the rabbit’s diets up to 25% inclusion levels without any detrimental effects on the performance, haematology, serum biochemistry and carcass and organ weights of growing rabbits.
