Abstract

Direct energy (electricity and heating) consumption was measured from one broiler house in southern Finland. CO₂ emissions were also calculated. Six broiler flocks were reared per year with an average of 26 000 birds per flock. Heating constituted the major energy input, averaging 1.3 kWh kg^-1 of carcass weight. It varied greatly between seasons and was highest during the cold period. Using renewable energy for heating remarkably reduces CO₂ emissions compared to fossil energy. Electricity consumption averaged 0.08 kWh kg^-1 of carcass weight. The greatest energy saving potential can be found in heating. CO₂ emissions can be lowered to similar levels as in warmer countries by using biofuels for heating. Ventilation control is one possibility for direct energy savings in broiler production. Feed production is one of the key elements when total energy consumption is considered.
