Effects of Curcuma longa rhizomes (turmeric) on reproductive performance in rabbits in the humid tropics

Abstract

The purpose of this experiment was to determine the effects of graded levels of Curcuma longa (turmeric) powder on the kits sired by dosed male and female rabbits. Twenty rabbits (16 does and 4 bucks) 7 months of age were used for this experiment. The does and bucks were assigned to four groups (A – D) of 4 does to 1 buck per group. Groups A, B and C received 250, 500 and 1000 mg/kg body weight of turmeric powder reconstituted in distilled water. Group D (control) received 1 ml of distilled water. Dosing was done per os daily for 30 days before the buck in each group was allowed to cohabit with the dose of the corresponding group. Gestational length, litter body weights (at birth), litter size and crown-rump lengths were all measured. There were no significant variations (p>0.05) in the gestation length of does and litter body weight in all the groups. The mean litter size in Group B does was significantly higher (p<0.05) than that of Group D does. The crownrump length of pups from does in all the turmeric-treated groups (A, B and C) were however significantly (p<0.05) higher than that of pups from Group D. The results of this study showed that at 500 mg/kg of turmeric powder, the dose had improved reproductive performance than when given at a higher dosage (1000 mg/kg) of turmeric powder per os.
