In this study, the economic coefficient of 10 traits including birth weight, 3-month weight, 6-month weight, 12-month weight, survival before 3-month, survival before 6-month, ewe survival, cumulative survival, twining percentage and fertility percentage were investigated in four different production systems with mean number 250 ewe of karakul by bio-economic model in Fars province. The obtained results showed that 6-month weight had the highest importance among the above traits. 3-month weight, cumulative survival, twining and fertility rate, ewe survival, birth weight, survival before 3-month, survival before 12- month, survival before 6-month, had positive coefficients and 12-month weight, had negative coefficients in the following ranking.
