The objective of this study was to investigate the effects of wheat straw level on growth performance and carcass parameter of lambs fed high concentrate diets. Thirty-six Awassi lambs (17.9 ± 1 kg) were randomly assigned to four experimental high concentrate diets with various wheat straw levels in a completely randomized design for 58 days. The experimental diets were isonitrogenous (16% CP) and contained 0, 5, 10 and 15% wheat straw. Results gained indicated that intake of dry matter; crude protein and metabolizable energy of the high wheat straw diets (10 and 15%) were similar (P > 0.05) and significantly higher (P < 0.05) than low wheat straw diets (0 and 5%). Final body weight, total weight gain, daily weight gain and feed efficiency of the high wheat straw diets were significantly (P < 0.05) better than low wheat straw diets. Furthermore, the carcass parameters of the high wheat straw diets were significantly (P < 0.05) superior to low wheat straw diets. In conclusion therefore, it may be recommended that high concentrate diets for Awassi lambs should contain at least 10% wheat straw for good growth performance and carcass quality.
