Barley straw from four varieties (Arabi Abied (AA), ER/Apam (ER), C63 (C63) and Beecher (BE) with and without soybean meal supplement were compared for differences in voluntary feed intake and digestibility. Two sets of Latin Square Design with four mature Awassi male sheep were used. The results showed that the mean intakes of barley straw were 41.2, 34.8, 30.6 and 25.6 g/kg W**0.75 for the four varieties AA, ER, C63 and Be, respectively and 41.7 and 24.4 g/kg W**0.75 with and without supplementation of soybean meal, respectively. However, there was a significant (P0.05) difference between the intake of AA variety and the other varieties of barley straw. Supplementation with soybean meal increased apparent dry matter digestibility, but this was not significant
