Consumption of chicken and poultry as a source of animal protein in human nutrition has grown significantly in recent years in the world. Based on this, the present study was conducted with the aim of investigating the factors affecting the price of poultry and poultry meat in the market of Sari city by the generalized Leontif function. The statistical population is broiler production units in Mazandaran province (Sari city) with a history of more than ten years. Non-probability sampling and available type were obtained based on 50 production units. This study is equal to the information obtained on final production cost, producer selling price and consumer purchase price (main variables in this study). The price of chicken and poultry was paid. The generalized Leontif function was estimated by seemingly disordered equations (SUR) and Eviews11 software in the period 1991-1999. The results of short-term estimates showed that the intersection of technology and labor, the intersection of capital and labor, and the intersection of capital are 0.486, 0.615 and 1.141, respectively. The results of long-term estimation showed that the intersection of technology and labor, the intersection of capital and labor, the intersection of capital and technology and the intersection of capital in the long run are 0.458, 0.658, 0.451 and 1.125, respectively.
