Abstract :To examine the effect of supplementation of varying levels of the oil of Nigella sativa in Karadi lambs rations on nutrients digestibility, blood metabolites, and some rumen parameters, 18 Karadi lambs were allocated into three groups, and the first group was fed a basal diet as control whereas, the second insert ignore into journalissuearticles values(T2); and the third insert ignore into journalissuearticles values(T3); groups fed the basal diet being supplemented with 0.15 and 0.30% of DM Nigella sativa oil insert ignore into journalissuearticles values(NSO); respectively. All animals were fed individually on 1.5 kg/lamb/day. Results showed that dry matter insert ignore into journalissuearticles values(DM);, crude protein insert ignore into journalissuearticles values(CP);, organic matter insert ignore into journalissuearticles values(OM);, and crude fiber insert ignore into journalissuearticles values(CF); digestibility was not affected insert ignore into journalissuearticles values(P>0.05); by NSO supplementation. Also, supplementing NSO had no significant effect on serum total protein insert ignore into journalissuearticles values(TP);, albumin insert ignore into journalissuearticles values(Alb);, globulin insert ignore into journalissuearticles values(Glb);, triglycerides insert ignore into journalissuearticles values(TG);, cholesterol insert ignore into journalissuearticles values(Chol);, high density lipoprotein insert ignore into journalissuearticles values(HDL);, and very low-density lipoprotein insert ignore into journalissuearticles values(VLDL); concentrations. There was an increasing trend insert ignore into journalissuearticles values(P=0.07); in LDL concentration of lambs fed on T2 and T3 as compared to control. Neither treatment nor interaction between time and treatment had an effect on rumen fluid pH. A significant decrease insert ignore into journalissuearticles values(P=0.008); was noted in rumen fluid pH value with the advances of time post feeding. The ammonia-nitrogen concentration in rumen fluid was generally lower upon oil supplementation, and it was significantly insert ignore into journalissuearticles values(P=0.03); decreased in the T2 group at 4 hours following morning feeding. It can be concluded that supplementing with 0.15 and 0.3% /DM of NSO showed a reduction in rumen ammonia-nitrogen while it had no effects on nutrient digestibility and blood metabolites in Karadi lambs.
