The total of 16 Awassi male lambs (4-5 months ages and 19.96 kg body weight) were divided randomly in a complete randomized design into four groups, to investigate changes in growth performance and digestibility of lambs fed different levels of lemongrass leaf powder (LLP, 0, 2, 4 and 6 g/head/day). There was significant superiority in lamb's total weight gain fed 2 and 4 g of LLP/head/day compared to those fed 0 and 6 g of LLP/head/day. Average daily gain (ADG) was significantly superior in lambs fed 2 and 4 g of LLP/head/day than those fed 6 g/head/day and control diet. The feed conversion ratio was improved in lambs fed 2 and 4 g LLP/head/day compared to fed on 0 and 6 g of LLP/head/day. The diet digestibility of dry matter and organic matter improved superiority in lambs fed 2 and 4 g of LLP/head/day compared to those fed on 0 and 6 g of LLP/head/day with no changes in diet digestibility of crude protein, crude fiber, ether extract, and nitrogen-free extract. It can be concluded that low levels of addition (2 and 4g/head/day) of lemongrass leaf powder enhance the digestibility and growth performance of Awassi lambs.
