Therefore, in this study efficiency of 60 beef cattle industrial farms with emphasis on environmental aspects were determined using Stochastic frontier production function. Results indicated that efficiency of farms with environmental indices was significantly lower. Education, experience and attending feed and health extension sessions had significant impact on efficiency of farmers.
