Twenty-four male lambs with an average weight of 28.73±3.64 kg and age of three months were assigned to four treatments with 6 lambs for each treatment in a completely randomized design. The treatments included: the control (basic diet), treatment 1: basic diet + 10 grams of supplement (60% cumin, 30% coriander and 10% peppermint), treatment 2: basic diet + 10 grams of supplement (45% cumin, 45% coriander and 10% peppermint), treatment 3: basic diet + 10 grams of supplement (30% cumin, 60% coriander and 10% peppermint). Blood was taken from the jugular vein of the lambs at the end of the experiment. DMI was not affected by treatments. Average daily gain (ADG) in the treatment 1 was higher than that of control treatment. Hemoglobin, PLT, RBC, and WBC, percentages of lymphocytes, monocytes and neutrophils were not affected by the supplements. No significant difference was observed between the experimental and control treatments in terms of blood glucose and triglyceride concentrations. Blood urea was higher in the treatments 2 and 3 than in the control. Aspartate aminotransferase and alanine aminotransferase increased in treatments 2 and 3 compared to the control. Alkaline phosphatase and gammaglutamyl transpeptidase in the treatment 3 were different from the control. Glutathione peroxidase and superoxidase dismutase did not change, but the antioxidant capacity in experimental treatments decreased compared to the control. The results showed that the addition of 10 gram of cumin, coriander and peppermint mixture with ratios of 30, 60 and 10, respectively, improved the performance of Roman lambs and feed efficiency without having an adverse effect on blood metabolites.
