Farm rambouillet ewes

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.
