Abstract:

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. Based on these classifications, the significant effects were adjusted for performance traits. The overall least squares means were 3.17±0.04 kg, 13.97±0.14 kg, 19.08±0.20 kg, 24.65±0.25 kg and 28.01±0.23 kg, for BW, 3MW, 6MW, 9MW and YW, respectively. The effect of period of lambing and sex of lambs were significant (P<0.01) on all the body weight traits. The effect of season of lambing was non-significant on all traits. The effect of type of birth i.e. single and twinning was highly significant only on birth weight. Males were heavier than females for all the body weight traits. It can be concluded from the present study that non-genetic factors affecting the growth traits in Rambouillet sheep.
