This research was conducted to modeling of energy consumption trend and economic- environmental indexes assessment of broiler production in Khorramabad County. The data were collected through interviews and questionnaires for a growing period of 2015. According to results, the total average of input and output energies were obtained 163699.27, 26730.64 MJ/1000Birds, respectively The Cobb-Douglas function results showed that the effects all inputs were positive on the yield. The results of the sensitivity analysis showed that an increase of 1 MJ in energy inputs of human labor, equipment, fossil fuel, feed and electricity will lead to an additional increase in yield by 0.388, 0.055, 0.009, 0.016 and 0.006 kg, respectively. The benefit to cost ratio 1.21 was determined. The indexes of global warming potential, acidification and eutrophication for production of 1 ton live weight were estimated to be 5272.7 kg CO2-eq, 62.56 kg SO2-eq and 22.56 kg PO4-eq respectively.
