This study was carried out to evaluate testicular and epididymal weights, morphometry, sperm reserves and sperm production of rabbit bucks fed Moringa oleifera leaf meal (MOLM), MOLM supplemented with garlic (GR), ginger (GG) or black pepper (BP). The diet was formulated to contain 6% MOLM and supplemented with GR, GG or BP at 700g/100kg diet. The study used 25 mature (age between 6 and 7 months and average weight of 2196±204 g) cross bred (mixture of crosses from California, Chinchilla, New Zealand White and Dutch rabbit bucks and lasted for three months. Parameters monitored was total testis volume, testes density, complete testis sperm reserve, complete caudal epididymides sperm reserve, daily sperm production (DSP) and daily sperm production per gram parenchyma (DSP/gP). A completely randomized design was used and the data obtained was analyzed using the general linear model procedure of SAS while means separation was done using pairwise difference (Pdiff) method. Total testis volume and testes density were significantly (P< 0.01) lower and higher respectively from the MOLM fed bucks than the supplemented groups. Complete testis sperm reserve was significantly (P<0.05) lowest in bucks fed MOLM + GG diet than the other groups. Complete caudal epididymides sperm reserve was also significantly (P<0.01) higher from MOLM fed bucks than the supplemented groups. DSP was significantly (P<0.05) lowest from MOLM + GR fed bucks. DSP/gP was significantly (P<0.01) highest from MOLM + BP fed bucks. It is recommended that to improve caudal epididymides, epididimydis sperm reserve and DSP/gP, rabbit bucks should be fed MOLM, MOLM + GG or MOLM + BP diets.
