Determinination of Energy Indices of Broiler Units in Alborz province

Poultry industry is one of the biggest and most developed industries in Iran. One of the important issues in broiler industry is the energy consumption. In this study, the energy consumption flow and the amount of energy production were investigated for broiler farms in Alborz province. Data were collected through interviews and questionnaires. Input energies were the feed, fuel (natural gas and diesel), electricity, labor, equipment and chicken, and the output energies were the broiler and manure. The total of input and output energies obtained were 125.2, 24.9 GJ/1000Birds, respectively. Energy indices, including energy ratio, energy efficiency and specific energy were obtained were 0.2, 0.019 kg/MJ and 52.55 MJ/kg, respectively. The highest share of energy consumption belonged to fuel (gas and diesel) with 50.84% and feed with 42.43% , and the chicken and labor with 0.39 and 0.06 % were the lowest share among the input energies.
