تقدير دالة إنتاج الحليب للبقرة بمشروع الهيرة الزراعي

الملخص

The main objective of this research paper is to estimate a milk production function per cow during a period of twelve months in 1989. Cobb-Douglas function was used to show the relationship between the dependent variable (milk production per cow), and the independent variables (concentrate intake per cow, green forage intake per cow, and dry forage intake per cow). All relevant data were collected from the official records of Alhira Agricultural Project for Poultry and Milk Production. The ordinary least square technique was used as an econometric tool to estimate the proposed multiple regression function. The green forage, and dry forage intake per cow had almost the same effect on milk production per cow. The estimated milk production function was homogenous of a degree less than one, and showed a decreasing return to scale.
