Twenty four Awassi male lambs with (27± 1.78 Kg) initial weight, and 4 – 5 months of age ,were divided into four groups (6 lambs each), to study the effect of two levels of feeding on liver function, immunity, health status and quantity carcass characteristics. Two levels of feeding (low level (40:60) and high level (60:40) that supplemented with two levels of bakery yeast, Saccharomyces cerevisiae.These diets were offered to lambs once daily. Significantly increased(P<0.01) in total blood protein, albumin and (P<0.05) globulin with 40:60 level of feeding, while significantly increased(P<0.01) albumin and decreased globulin with 60:40 level of feeding.Total cholesterol, S. Total triglyceride, High density Lipoprotein (HDL) and Very Low Density Lipoprotein (VLDL) were significantly decreased (P<0.01) after 3hrs of feeding and no significant with Low Density Lipoprotein (LDL) in level 40:60, whereas significantly increased (P<0.01) of serum cholesterol concentration, S. Total triglyceride, High density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) and no significant in Very Low Density Lipoprotein (VLDL) in level 60:40 of feeding. The activities of some liver enzymes SC significantly increased (P<0.01) (AST) (GOT) but Lipase enzyme decreasedsignificantly(GPT) and totalbilirubin after 3hrs of feeding with 40:60.Whereas decreased (P<0.01)(GOT) ,(GPT) and total bilirubin in serum blood with 60:40 level of feeding .SC supplementation significantly increased(P<0.05) on skin weight gain (kg)with 60:40 concentrate : roughage ratio. On the other hand, no significant increase on offal's weight and heart girth of Awassi male lambs. In concolusion the obtained results refer to the using of SC as growth promoting agent for lambs to increase the nutritional value of low diet in order to decrease the diet costs
