Abstract
The main of this study is to estimate the production function which represents the optimum relationship between broiler weight as an dependent variable and soybean meals and corn as independent variables and then to calculate the quantity of the two factors which achieve the economic efficiency . To accomplish this goal seven production functions were estimated : Lineary , double logarithm , semi-logarithm , quadratic , quadratic with interaction term , square root and square root with interaction term by using OLS technique. The results showed that that double logarithmic function was the most suitable function according to statistical criteria , econometric criteria, economic criteria and biological criteria. The results also showed that the optimum quantity of soybean meal is 33% of corn quantity as the nature of logarithmic function entails a continuous increase as long as the ration is introduced to broiler and the producer would stop this when the production reaches the marketing age. In this age broiler meat would be acceptable to consumer in addition to that producer would evade an extra costs. Some economic derivatives were derived such as marginal rate of substitution , elasticity of substitution , Isoquant equation , Isoclines and elasticity of production.
