Abstract The effect of spraying rapeseed oil on the reduction of dust and ammonia concentrations and emissions, and on animal parameters was investigated in a dose-response study in a broiler house during three growing periods in four (round 1) or five rooms (rounds 2 and 3). The spraying rates varied per room, from 0 (control) to 24 mL oil m(-2) d(-1). Concentrations of PM10 and PM2.5 in incoming and outgoing air were measured. Production results (growth rate, feed intake, mortality rate) and foot-pad lesions were also determined. Regression analysis showed that a spraying rate of 6 mL oil m(-2) d(-1) reduced PM10 concentrations by 44% and PM10 emissions by 48%. At 24 mL oil m(-2) d(-1), the reduction was 82% for PM10 concentrations and 87% for PM10 emissions. For PM2.5, the lowest spraying rate of 6 mL oil m(-2) d(-1) was sufficient to reduce concentrations by 68% and emissions by 84%. The reduction achieved at higher spraying rates was not significantly greater. Emissions of PM10 and PM2.5 increased exponentially with the age of the broilers. A clear diurnal pattern was observed, with lower dust concentrations during the dark periods. Production results were unaffected by the spraying rate. A high rate of 24 mL oil m(-2) d(-1) increased the number and severity of foot-pad lesions. It is concluded that spraying rapeseed oil significantly reduces dust concentrations and emissions from broiler houses. To prevent adverse effects on broilers' foot-pad quality, it is recommended that the maximum rate should he 16 mL oil m(-2) d(-1).
