ixty  Virgin New Zealand White Rabbit Does(VNZWRD) during three consecutive reproductive cycles, with average initial age of six months and weighing 2.98 kg and servicing for the first time at seven months were allotted to four experimental diets. Sun dried Moringa oleifera leaves  replaced soybean meal by 0% (G_0%),25%(G_25%) ,50%(G_50%) and 75% (G_75%) .Results showed non significant differences in the total feed  intake(FI) and average body weight does on the different groups. The G_75%does had the highest FI (183.20 g/day) followed by G_25% (173.80 g/day) , G_50% (169.80g/day) whereas G_0% does had the lowest (168.40 g/day).There were significant differences in the litter size at birth (LSB) of does on the different groups .The G_75% does had the highest litter size at birth of(7.866) followed  by G_50% (7.622) and G_25%(7.377),while G_0% does had the lowest (6.422).Both litter weight at birth and litter weight at weaning were highest in G_75% (392.44 and 3162.73g), respectively with significant (p<0.01) different in litter weight at weaning across all levels of SDMOL. There were significant differences (p<0.01) in average milk yield during 21 across. Milk yield was higher in G_75% (2095.02g) followed by G_50%(2048.82g) , G_25%(2019.33g),while G_0% does had the lowest (1957.22g) (p<0.01).It can be concluded that  sun dried Moringa oleifera leaves can be used as additives without adverse effect on the reproductive performance of and  milk yield of does  rabbits.
