    Abstract: Effects of supplementary extruded oil seed on carcass characteristics and Conjugated Linoleic Acid (CLA) content of muscle in Mehraban male lambs were studied. The treatments included Control (C) diet C + 6% ECAS diet C + 6% ECOS diet C + 12% ECAS diet C + 12% ECOS diet C + 6% ECAS + 6% ECOS diet C + 12% ECAS + 6% ECOS diet C + 6% ECAS + 12% ECOS diet C + 12% ECAS + 12% ECOS diet C + 18% ECAS + 18% ECOS. About 60 Mehraban male lambs were used with the initial live weight of 34.3±2.12 kg and 5-6 months of age. The experimental period was 90 days and arranged in the completely randomized design. Carcass traits Dry Matter Intake (DMI) and CLA content in the muscle were significantly affected by different levels of ECOS and ECAS. There were linear and quadratic increments in the CLA content due to increasing in ECAS or ECOS from 0-12% of diet. Increasing of the ECOS and ECAS inclusion from 0-18% caused to increase in the CLA content but had negative influence on the carcass traits liver weight and DMI of lambs.
