The aim of the study was to investigate ammonia (NH3) emission in the stable for pigs and cattle. Dairy cows, heifers and calves were kept in tie-up and bulls in loose housing system. Gestating sows, weaners and slaughter pigs were housed in group pens and lactating sows were kept individually. NH3 emission was expressed by production year (dairy cows, heifers and bulls) or by period (calves and all pigs)
