This study was conducted to evaluate the effect of supplementation of Acacia Albida (AA), Acacia Seyal (AS) and their mixture on feed intake and digestibility of local sheep fed a basal diet of barley straw (BS)”. “Twenty four yearling intact male sheep with initial BW of 16.6 kg ± 2.4 (Mean ± SD)” were blocked in to six based on initial BW and animals within a block were randomly assigned to treatments. Treatments were ad libitum barley straw(BS) and 100 g wheat bran (WB) alone (T1) or supplemented with 200 g of dried leaves of Acacia Albida(AA) (T2), Acacia Seyal(AS) (T3) and a 1:1 mixture of AA:AS (T4). The feeding and digestibility trial “was” conducted for 90 and 7 days, respectively. Dry matter (DM) intake of BS was in the order of T1>T2=T4>T3 (P<0.05). Total DM intake (500, 650, 597 and 636 g/ day (SEM=12.96) for T1, T2, T3 and T4, respectively) was lowest for T1, highest for T2 and T4 and intermediate for T3 (P<0.05). Total CP intake “were”38, 77, 65 and 71 g/day for T1, T2, T3 and T4, respectively, and was increased by supplementation (P<0.05). Among the supplemented treatments, T2 had higher (P<0.05) CP intake than T3, while the CP intake of T4 was similar with T2 and T3. Apparent digestibility of DM and CP increased (P<0.05) and that of NDF and ADF was unaffected (P>0.05) by the supplementation. Therefore, result of the current study suggested that 200g AA leaf meal supplementation to barley straw basal diet to be better in feed intake and digestibility.
