In Exp1, twelve adult male Barki rams (43.56 ± 0.5 kg body weight) were divided into similar three groups (4 of each) for three experimental rations consisted of 50% concentrate feed mixture (CFM) plus 50% roughage either clover hay (CH) or treated barley straw (TBS) or TBS with condensed molasses soluble (CMS) for C (control), T1 and T2, respectively. However in Exp.2 ten growing Barki lambs (28.32 ± 1.25 kg body weight) were divided into two groups, group one (C) fed as the control ration (50% CFM + 50% CH) while group two fed 50% CFM +33% TBS +17% CMS). Rations were offered to animals at 3% of body weight (DM basis). The results showed that digestibility's of DM, OM, CF and EE didn{u2019}t differ (P<0.05) among all rations, while CP digestibility recorded higher (P<0.05) value in T2 compared to T1 rations.The TDN values were ranged from 53.6 to 56.12% insignificant (P<0.05). Values of DCP were surpass (P<0.05) for T2 compared to C and T1, being 9.87, 9.11 and 7.28%, respectively. All parameters of rumen liquors and blood serum were within the normal ranges. Body weight gain and feed conversion of growing lambs didn't differ (P<0.05) also wholesale cuts and organs of T2 were similar to those of control (P>0.05. The economic efficiency was better for T2 group being higher by 15.3% than control group. Finally, treated barley straw with condensed molasses soluble could be used as good roughage (such as clover hay) in ration of growing Barki lambs in arid and semi-arid regions ER -
