This experiment was conducted to study the effect of barley straw treated with liquid diel based on dry matter basis ( 0, 5,10 and 15% ) on ita daily intake, digestion coefficient, lave weight gaiia and feed conversion ratio ,by using twenty four individually penned intact Awassi male lambs ,with age of 7-8 months and average live weight 27.8 kg.

The results indicated significant (P<9.05) decrease in liquid diet treated straw content of neutral detergent fiber (NDF) and highly significant (P<0.01) increase in acid detergent fiber (ADF), and acid detergent lignin (ADL).The results also indicated highly significant (P<0.01) increase in digestion coefficient, dash feed intake of dry matter, organic matter and nitrogen by lambs fed liquid diet treated straw' as compared with those fed untreated straw The result also indicated highly increase (P<0.01) in daily gain of Jamb fed liquid diet treated straw as compared with those fed untreated straw.
