In order to estimate economic values of productive traits (meat, milk and wool) in Taleshi native sheep breed of Iran, records from economic parameters and performance of local Taleshi flocks were used. The economic values of traits were used to select the maximum profit estimation also to study the sensitivity rate of the model the effects of 20 percent increase / decrease in the price of milk feed and other costs were estimated. Average values of estimated absolute economic values for meat, wool and milk were 1229798.139, 833959.858 and 27174.717 Iranian Rial (IRR)/kg, respectively. Life analysis of economic values showed that these values were changing and sensitive to the variable management and nutrition costs, although they were less affected by the change in total cost of the growing system of Taleshi sheep.
