The aim of this study was to investigate the evaluated energy efficiency and effect of poultry house size on energy productivity in three different capacity. Capacities of houses were 10,000 (3 housings), 20,000 (2 housings) and 28,000 (1 house) birds per production period and were assigned as HI, HII and HIII respectively. For calculating the effective factors on energy efficiency in the studied poultry housing, this experiment was conducted in a completely randomized design as basis in nested pattern. Utilized energy in the form of fuel, electricity, feed, labour, wood shaving, chicks and utilized chemical as inputs and litter and broilers as outputs were measured in each production period. Result shows that inputs significantly decreased with increasing the size of poultry house from 10,000 to 28,000. Thus, division input energy and cost in production of HIII had better productivity than the other units. Also, experiment treatment had significant effect on energy indexes (p<0.01).

Key words: Energy efficiency, inputs, outputs, poultry housing capacity.
