This study was conducted in the animal field of the College of Agriculture University of Tikrit for a period of 70days precession this period 14 day as adaptation starting from 8/10/2020 to 16/12/2020. Sixteen Awassi lambs were used, aged 5-6 months, with an average weight of 26.2 ± 0.3 kg. The experimental treatments were, first, the control 98% barley (farmer diet), the second 88% barley + 5% soybean meal+ 5% vegetable fat and the third 83% barley + 10% Soybean meal+ 5% fat and the fourth 78% barley + 15% soybeans+ 5% fat with addition to 1% salts and 1% vitamins and minerals for all treatment. The lambs were fed concentrate feed at 3% of live weight on a dry matter basis with 100 grams/day/lamb straw. The results showed that second, third and fourth treatments significantly (P≤0.05) improved final weight, average daily weight gain and feed conversion ratio compared to the first treatment, the third and fourth treatments (P≤0.05) increased in the daily weight gain, final weight and feed conversion efficiency compared to the second treatment. Significant (P≤0.05) differences were also found in some biochemical characteristics of blood, as increased in percentage of Triglycerides, blood urea and albumin in fourth treatment of lambs compared to ether experimental treatment, while no significant differences were found between experiment groups in proportion of glucose, creatinine, total protein, and the enzyme AST and ALT. note that all blood measurements of the experiment lambs were within normal limits.
