The impact of dairy cows and fattening pigs housing system on ammonia emission rate has been studied under production conditions. During the housing period, the NH3 emission from an animal place in the insulated cowshed of tied cows and in the cowshed with partly slatted floor was the same - approximately 29 g per day, and in the uninsulated cowshed it was greatly less (17 g per day). Ammonia emission during 220-d housing period from animal place in an uninsulated cowshed is 3.7 kg, and in an insulated one 6.4 kg. The lowest emission (2.2 kg for pig per year) has been achieved while keeping pigs on abundant straw litter, which was changed every week. Applying slatted floor system, ammonia emission rate is 2.5 kg pig per year.
