摘要：This study was performed with the purpose of determining the energy usage efficiency of egg chicken reared. To achieve this study, the energy input-output of 1000 egg chickens reared was calculated. This study was done an egg chicken's farm in Isparta province of Turkey. The energy input and output were calculated as 588779.56 MJ/1000 chickens and 1107962.30 MJ/1000 chickens in egg chicken reared. The composition of energy inputs was 88.51% (521,147 MJ/1000 chickens) feed energy, 8.24% (48,507 MJ/1000 chickens) fuel energy, 1.71% (10,054.80 MJ/1000 chickens) electricity energy, 1.01% (5967.81 MJ/1000 chickens) machinery energy, 0.37% (2,165.80 MJ/1000 chickens) human labour energy, 0.08% (464.85 MJ/1000 chickens) chicken's energy, 0.07% (392.92 MJ/1000 chickens) transportation energy and 0.01% (79.38 MJ/1000 chickens) water energy. Energy usage efficiency, energy productivity, specific energy and net energy for egg chicken reared were calculated as 1.88, 0.03 kg MJ~(-1), 31.63 MJ kg~(-1) and 519182.74 MJ/1000 chickens, respectively. Feed energy was determined as the highest ratio (88.51%) of total energy input. According to study results, egg chicken reared can be accepted as economic in terms of energy usage efficiency.
