Abstract
Knowledge of studying energy consumption in production operations is a useful method for determining energy-consuming areas, which are determined by analyzing the amount of energy consumed in production operations. The required information was collected through a questionnaire and face-to-face interviews with broiler breeders in Diwandarreh city. The total input energy was estimated to be 250574.01 MJ for 1000 chickens. Energy indices including energy ratio, energy efficiency and specific energy for poultry farming were 0.11, 0.1 Kg/MJ and 96.48 MJ/Kg, respectively, and the total input energy amounted to 250990.01. In this study, the total production cost of 1000 chickens in Diwandarreh city was about 108.83 million Rials, of which about 102.25 million Rials belonged to the variable cost of production and about 6.58 million Rials belonged to the constant cost. The benefit-to-cost ratio index was also estimated as 1.19. Finally, the total efficiencies for chicken meat and chicken manure were 23.87 and 14.8 kg per million Rials, respectively. The results of input sensitivity analysis showed that the elasticity of chicken inputs, gas fuel, manpower, corn, soybean, minerals, fatty acid, dicalcium phosphate, and disinfection having coefficients of 0.17, 0.35, 0.03, 0.18, 0.2, 0.72, 0.54, and 0.26 were positive and less than one. The amount of MP (final productivity) of these was calculated as 1.3, 0.009, 09.05, 0.07, 0.05, 9.45, 0.35, 0.95, 0.02 and 25.97 respectively.
