Resumo:  The goal of this study was to evaluate the sustainability and efficiency of broiler production with regard to energy consumption in Ardabil province, Iran. To reach the goal, linear programming model and Data Envelopment Analysis (DEA) were employed.  Data were collected from the farmers using a face–to–face questionnaire performed in September–December 2014 period.  The DEA application results showed that the average values of technical, pure technical and scale efficiency scores of producers were 0.949, 0.988 and 0.960, respectively.   Also, energy saving target ratio for broiler production was calculated as 8.33%, indicating that by following the recommendations resulted from this study, about 12316.85 MJ/(1000 bird) of total input energy could be saved while holding the constant level of broiler production.  The results of linear programming model revealed that by using of optimum energy, producers could increase average yield by 17.6%.   Also the results indicated that the existing productivity level could be achieved even by reducing the existing energy use level by 13.89%.  Diesel fuel, natural gas and electricity energy inputs had the highest potential for saving energy in two methods; so, if inefficient producers would pay more attention towards these sources, they would considerably improve their energy productivity.
