The study was conducted in female Black Bengal goat to investigate the effect of non hormonal factors on reproductive efficiency. Female kids of three months of age were placed in three groups with five numbers in each group; 1st TG with supplementary nutrition and a buck, 2nd TG with supplementary nutrition and 3rd TG as control. Due to permanent exposure of buck and good plane of nutrition, the animals under TG 1 attained puberty significantly (P<0.01) earlier than other two groups. Average body weight of animals of TG1 (10.0 kg) was also recorded to be lowest. Most failure of conception was noted in TG 1 as reflected by its significantly higher (P<0.05) number of services (3.6) than other two groups (2.2 and 2.0 respectively). Nonsignificant (P>0.05) variation in gestational length indicated non-hormonal factors had no effect on length of gestation. Highly significant (P<0.01) variation in respect to age of 1st kidding was observed, the animals under TG 1 took least time, but body weight of animals of TG 3 was least. Post-partum estrus was also recorded to be earliest (3 to 6 weeks) in first group of animals than the other two.
