The Evaluation of Productivity of Layer Farms of Tehran Province

  The objective of this study was to evaluate the productivity of layer farms of Tehran province. Data (in the period of 2004- 2007) were gathered through filling out of 70 questionnaires. Transcendental production function showed the best fit and was used to calculation of marginal productivity and elasticity of production.   The results showed that pullet number, feed consumption and labor had significant effects on egg production. The elasticity of production each three variables were positive and between 0 and 1; indicative of using the variables in second economical region. Total productivity of input variables was equal to 0.26; namely with each one of total variable was produced 0.26 kg egg. Farm managers with higher graduation showed better productivity. In according to the results with focusing on significant variables can remarkably improve egg production in Tehran province through increasing productivity of input variables.   JEL Classification : D21, D24, O42
