چکیده مقاله :
Quantitative analysis of production through evaluation of inputs consumption quantity is of main principles in agricultural policies, which is followed by increasing in production through optimal use of resources. This study has been conducted to estimate different types of production functions in mechanized farms of broiler chicks located in Gorgan city. Cross-section survey data were gathered in spring of 2009 via filling in 71 questionnaires and also interviews with managers of broiler chicks farms located in Gorgan were made. Then, according to viewpoints of experts, mechanization level of each broiler chick farm was assigned and grouped into two mechanized and semi-mechanized groups. Afterward, Linear, Cobb-Douglas and Transcendental production functions were estimated and analyzed for the mentioned groups. Results showed that the best functions for mechanized and semi-mechanized farms are linear and Cobb-Douglas models, respectively. Also, return to scale in mechanized and semi-mechanized broiler chick farms showed diminishing and ascending trends, respectively.
