The data on reproductive performance of 502 Nellore Brown lambs born during 2006 to 2011 maintained at Livestock Research Station, Mamnoor, Warangal district which is a constituent of Sri P.V. Narsimha Rao Telangana Veterinary University, Hyderabad, were utilized for the present study. The overall least squares mean age at first service(AFS), age at first lambing (AFL), service period (SP) and lambing interval (LI) were 593.55±6.74, 742.53±6.75, 155.03 ± 10.71 and 304.41 ± 10.71 days, respectively. Year of birth had shown highly significant (P≤0.01) effect on all the reproductive traits studied. The season of birth significantly (P≤0.01) influenced service period and lambing interval only. The parity of the ewe had significant (P≤0.05) effect on service period and lambing interval. The significant effect of non-genetic factors plays an important role in reproductive performance of animal so higher emphasis on management practices, nutrition and health cover will improve the reproductive performance of animal.
