Abstract
The main aim of this study is to estimate the production function which represents the optimum relationship between broiler weight as dependent variable and sunflower and maize as independent variables and then to calculate the quantity of these two factors which achieve the economic efficiency. To accomplish this goal seven production functions were estimated: Lineary, double logarithm, semi-logarithm, quadratic, and quadratic with interaction term, square root and square root with interaction term by using OLS technique. Results showed that double logarithmic function was the most suitable function according to statistical, econometric, economic and biological criteria. The results also showed that the optimum quantity of sunflower was 9.31% of maze quantity according to the logarithmic function entails a continuous increase as long as the ration is introduced to broiler producer would stop when the production reaches the marketing age. In this age broiler meat would be acceptable to consumer in addition to that producer would avoid an extra costs. Some economic derivatives were derived such as marginal rate of substitution, elasticity of substitution, isoquant equation, isoclines and elasticity of production. Of the reasons for selecting the function logrithamic. significance parameters as independent variables to (T-test). A whole function as significance (F-test).The value of adjusted coefficient of multiple determination is (0.928). The results showed. Free form. Autcorrelation hetroscedasticity and Multicollinearity. That the teachers agreed with reference to operative economic theory.
