This paper presents a profit function developed for sheep-for-meat farms in the cooperative environment of Extremadura region (Spain). For that purpose, data from 115 farms belonging to three sheep cooperatives have been analyzed. The method used to determine the profit function (expressed in Gross margin per ewe)was the partial least squares regression (PLSR). The obtained equation showed a R2 of 0.82 in the validation stage and the variables that best explained the behavior of the profit variable were: income from subsidies, lambs sold per ewe, leasing costs, cost of concentrate, Kg concentrate used for fattening and cultivated area of the holding.
