Rambouillet sheep

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.

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 present study was performed to assess the usefulness of laparoscope in the embryo transfer programmes in sheep and to evaluate conception rate after single, double and triple embryo transfer in farm bred rambouillet ewes. A total of 21 freshly collected embryos were transferred in 11estrus synchronized ewes to yield nine lambs.

Data on growth traits of 7151 animals used in present study were collected from the history sheets of Rambouillet sheep maintained at Government Sheep Breeding Farm, Zaban, Reasi, J&K, India, over a period of 16 years (2000-2015). Body weight traits were birth weight (BW), three month body weight (3MW), six-month body weight (6MW), nine-month body weight (9MW) and yearling weight (YW). The data were classified to study the major effect of non-genetic factors like period of lambing, season of lambing, sex of lamb and type of birth.
