Silage of halophytic shrubs was fed as a basal diet supplemented with 3 energy sources: concentrate feed mixtures (CFM) (T2), ground date seeds (T3) and barley grains (T4). Berseem hay and CFM were given as a control diet (T1). 36 growing male sheep were divided randomly into four equal groups and offered one of the fattening diets for 6 months.. Neck and flank per cent varied (P less than 0.05) among animal groups. Supplementation with barley or date seed led to increase carcass weight, kg carcass per cm2 LD, total fatty tissue and gm fat/cm2 LD indicating to producing marbling meat. Feed efficiency appeared to be relatively comparable. Halophytic silage supplemented with barley grains or ground date seeds, may be recommended for fattening sheep since the production costs of one kg gain in carcass was reduced by 47.5 per cent compared to the conventional diets.
