Building of large pigsties with deep litter and without litter which use liquid manure removal systems has become a wide practice nowadays. The indoor climate parameters of the working environment have an impact on the human capacity for work and productivity of animals. Enlargement of pigsties is accompanied with problems regarding the achievement of the required indoor climate of the working environment. For the purpose of studying of the pigsties with different animal-keeping technologies of the simultaneous effect of temperature and relative humidity on the emission ammonia content in the air of pigsty, were measured in summer and in winter pigsties in above pig-pen at the height of 1.5 meters from the floor were measured daily. Data logger equipment, relevant sensors and the content of ammonia in the air measured by using Gas Monitor Pac III equipment were used for the study. The measurement results were statistically processed by using computer programmes AMR Win Control, Pac III Software3.nn, SAS and MS Excel.
