Reproductive traits of 1976 ewes of Rambouillet sheep maintained at Government Sheep Breeding and Research Farm, Reasi, Jammu, India for 10 years (1998-2007) were recorded. Genetic parameters were estimated for age at first fertile service, age at first lambing, litter size at birth (1976) and inter lambing period. Estimates of heritabilities for animal genetic and permanent environmental and maternal genetic effects were mainly low for all traits under study. The high and positive genetic and phenotypic correlations were found between AFFS and AFL, low and positive between ILP and AFFS, ILP and LS whereas negative phenotypic correlations were found between AFFS and ILP, LS and ILP. Highly significant genetic and phenotypic correlation between AFFS and AFL indicates that selection on the basis of one trait will automatically improve the other.
