Abstract/Description: | Our Indian rangelands are covered with a wide variety of vegetation viz. grasses, bushes, forbs, shrubs and trees. The limited concentrate supplementation in addition to free grazing on community rangeland substantially improves production (Chaturvedi et al. 2001, Chaturvedi et al. 2003) and reproduction (Chaturvedi et al. 2006, Islam et al. 2007) performance of ewes. It is widely accepted practice in sheep husbandry to provide ewes with extra energy supply (flushing) for 2–3 weeks prior to and during breeding, for the purpose of increasing the number of lambs produced. Failure to flush the ewes may result in delayed estrus activity and ovulation (Gunn et al. 1979), fertilization failure (Restall et al. 1978) and embryonic mortality (Rhind et al. 1989). In another report, the litter weight increased by extending the flushing period from 17 to 34 days, whereas the effect on litter weight was minimal (Sormunen-Cristian and Jauhiainen 2002), but flushing does not always improve the lambing performance (Crocker et al. 1985). The information on the effect of flushing on nutrient utilization and reproductive performance of ewes under farmer’s field is limited. The present study was therefore, undertaken to evaluate the effect of flushing of ewes with concentrate just before the mating season on their nutrient utilization and reproductive performance at farmers’ field. |
