Milk and dairy production is the most important of calcium resources and its consumption quantity is sign of nutrition situation and society health. According to the importance of milk production and industrial dairy cattle breeding at food security and GDP, and also the role of Isfahan province in Iran's animal husbandry sector, the purpose of this study was to survey the effective factors on production and profitability of milk in dairy cattle farms of Isfahan Township. Data collection was done by completing via 90 questionnaires simple random sampling 2011. Based on well-known econometric criterio. Cob-Douglass function was selected as the best of type production function. Results of production function estimation showed that variables of annual consumption quantity of power, alfalfa, sorghum, chaff, number of worker have the effectiveness of positive and significantly on milk production. Sorghum consumption has the most effect. The total of estimated coefficient is smaller one and positive, therefore, input consumption performs in economic region. Results of normal profit function estimation showed that prices of alfalfa, sorghum, chaff; medicine cost and postiche inseminate cost have the effectiveness of negative and significantly, but annual wage the effectiveness of positive and significantly on profitability. Also, input price of sorghum has the most effect on dairy cattle  farms profitability.
