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, the between years 2015-2016. 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% (521147 MJ/1000 chickens) feed energy, 8.24% (48507 MJ/1000 chickens) fuel energy, 1.71% (10504.80 MJ/1000 chickens) electricity energy, 1.01% (5967.81 MJ/1000 chickens) machinery energy, 0.37% (2165.80 MJ/1000 chickens) human labour energy, 0.08% (464.85 MJ/1000 chickens) chickens 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.eninfo:eu-repo/semantics/openAccessEgg chicken reared, energy usage efficiency, energy productivity, net energyArticleQ4WOS:000498337300019
