A total of 4186 records of Rambouillet sheep maintained at Government Sheep Breeding and Research Farm, Reasi, Jammu, India for 10 years (1998-2007) were analyzed to estimate the reproduction traits in relation to non-genetic factors viz., season of lambing and year of lambing on Age at first fertile service, Age at first lambing, litter size at birth and interlambing period. The overall mean for Age at first fertile service (AFFS), Age at first lambing (AFL), litter size at birth (LS) and interlambing period (ILP) were 727.17±2.03 days, 877.04±2.01 days, 1.05±0.00, and 368.34± 0.22 days with corresponding coefficient of variations 12.40%, 10.21% 21.51% and 2.67%, respectively. In present study, year and season had non- significant effect on AFFS, AFL, LS and ILP.
