This study was conducted to determine the chemical composition of black seed meal and the effect of replacing soybean meal with black seed meal on blood parameters, nutrient digestibility, performance and carcass characteristics of Zandi fattening lambs. Eighteen weaned male lambs with an average body weight of 23.5±1.5 kg in three groups of six heads were fed in individual pens with experimental diets, in a completely randomized design. Experimental diets included 1) control (basal diet with 12% soybean meal and without black seed meal), 2) diet containing 6% soybean meal and 9% black seed meal and 3) diet containing 18% black seed meal without soybean meal. The amount of DM, CP, EE, NDF, ADF, insoluble nitrogen in acidic detergent and ash of black seed meal were 97.53, 31.26, 15.16, 25.95, 14.2, 0.69 and 5.07 percent, respectively. Replacement of soybean meal with black seed meal in the diet of fattening lambs had no effect on final weight, dry matter intake, daily weight gain, feed conversion ratio, carcass percentage and characteristics and fat tail size. Albumin and total blood protein of lambs fed diets containing 18% of black seed meal were higher than other treatments (P<0.05). Blood glucose, triglyceride, cholesterol and urea nitrogen levels were not affected by experimental treatments. The digestibility of dry matter, organic matter, fat and protein was similar among the experimental treatments. The results of experiment showed that the use of black seed meal in the diet of fattening lambs up to 18% had no negative effect on the performance and digestibility of dietary nutrients.
