In: Egyptian Journal of Sheep and Goats Sciences 2012.v.7(2)Summary: Towards identifying potential production of Barki sheep, this study was implemented to evaluate performance of Barki ewes at late gestation and lactation period by feeding them on standard allowances (Tomi 1963) vs. a higher level 120% of that allowances. Twenty Barki ewes 2-3 years old and 46.5 kg live body weight at the last six weeks of gestation were divided into two equal groups (10 ewes each) that received 100% and 120% of Tommi allowances (1963). The first group (T1) and second are (T2) were fed 1 and 1.2Kg /head/day concentrate feed mixture, respectively beside 2 kg berseem and 200g rice straw / head. The weight of lambs at birth and weaning were not influenced by the level of feeding. The average daily gain of lambs in T2 was improved by 8.0% compared with T1, but the differences between the two treatments were not significant.
