AbstractSixteen male Awassi lambs 4-5 months old and 25.4Kg live body weight were used in this study, the lambs distributed into four groups. The first group fed a control ration containg 13.1% C.P. and 2.71 M.cal. as M.E., while the 2nd , 3rd and 4th ration, contained 2,4 and 6%.Nigella sativa meal respectively. The wheat straw added 1% of B.W. for all the groups. Feeding period was (90 days).The results showed that the control group was significantly (P<0.01) better in daily gain 157, 122, 107, 101gm/ day and total body gain 14.1, 11.00, 9.6, 9.1kg than the others which fed the Nigella sativa meal. The four group Lambs showed 8.39, 9.99, 10.5 and 10.54kg D.M/1kg body weight gain as average feed conversion rate respectively. Average hot carcass weight was found significantly (P<0.05) in control group (19.4 kg) compared with the 4th group (16.7kg). The statistical analysis did not show any significant differences in dressing percentage and carcass grade. However the groups that fed Nigella sativa meal showed a significant (P<0.05) effect on fat thickness at the 12th rib (3.9, 3.8 and 3.9mm) as compared with the control group (2.8mm). The chemical analysis of meat indicated a significant (P<0.05) Versions between the four groups when the higher C.P.
was found 17.1% for the control group and E.E was the higher (26.8%) for the 4th group meat.
