This study was conducted to evaluate the effect of feeding graded levels of Acacia saligna leaves hay (ALH) on the performance of sheep performance. The experimental work was divided into two experiments. The first experiment was conducted on Barki ewes during late pregnancy and lactating season. Forty ewes (ten ewes per group)aged 3-5 years old at the last third of pregnancy and weighed 38.0±1.2 kg were fed with 0, 20, 40 and 60% of ALH as berseem hay replacement in a completely randomize design for 250 days. The results showed non-significant differences in daily DM intake and digestibility coefficients for DM, EE, NFE and cellulose. Diets of 40% and 60% ALH showed higher (P<0.05) OM, CF, NDF digestibility comparing to 20% ALH and control diets. The highest (P<0.05) NB was recorded for ewes fed 60% followed by 40% ALH. The incorporation of ALH at levels 20, 40 and 60% resulted in non-significant differences in live body weight at all periods of the late pregnancy. Pregnant ewes fed 60% ALH diet recorded the highest (P<0.05) body weight gain (Kg), daily gain (g/day) and milk yield. Birth weights of lambs were not significantly affected. Blood urea decreased (P<0.05) with the graded percentage of ALH inclusion instead of Berseem hay. The results of this study revealed that inclusion of ALH up to 60% instead of dietary berseem hay could be best for improving nutrient utilization and performance of Barkiewes during late pregnancy stage.
