This study has done with the purpose of technical estimation of dairy farm cooperatives of Kohgiluyeh and Boyer-Ahmad Province. Necessary statistics and information collected with help of questionnaire and interview with province cow owners and transcendental production diagrams has been chosen as selective diagram in analyzing the results.

With regard to coefficient meaning in selective diagram we get this result that the units of bran and salt place in third manufacturing zone (area), that is these units are use abundantly in province. Complementary Concentra units and workforce place in first zone (area); that is the production will increase in case of increasing these units. The average of technical usage of dairy farms has been 94 percent (at last 84%, at most 99%) that by improving management, averagely, we can increase technical usage about of 6 percent. Also the gap between the best and the weakest production is about 15% that can be improved by applying management approaches. The effective factors on technical efficiency have been analyzed and the results show that the experience, education level, and allocated area for each cattle affect the technical efficiency while factors such as family size and age affect statistics.
