The aim of the study is to determine the effects of different plane of nutrition during late pregnancy to lactation on the performances of ewes and their offspring to weaning. About 36 native Bengal ewes of last 7 weeks gestation were randomly assigned to four different groups (T0, T1, T2, T3). The T0, T1, T2 and T3 groups were supplemented a concentrate mixture at 0.0, 1.0, 1.5 and 2.0% of their body weight, respectively. Chopped German grass (Echinochloa polystachya) was provided as basal forages to ewes and a creep mixture (20 g/lamb/day) to the lambs from 2 weeks of age with a weakly increase of 10 g/lamb. The results shown that ewes dry matter intake (p < 0.01), milk yield (p < 0.05), days open (p < 0.01), live weight gain before lambing (p < 0.01) and at weaning (p < 0.01) and weight recovery from late gestation to weaning (p < 0.05) improved with high plane of nutrition. Higher weight recovery found in T2 group. Litter size had an effect on (p < 0.01) all weight traits of lambs and ewes milk yield. Sex of lamb also affects (p < 0.05) the weaning weight and daily gain of lambs.
