The investigations were carried out in a pig nursery on 985 piglets (554 experimental and 431 control piglets) for 50 days. The effect of natural zeolite (55 % clinoptilolite) used as a feed additive on the concentration of ammonia in the air was investigated as an important factor affecting the health and welfare of piglets. Our investigations included the determination of microclimatic parameters, aerial ammonia and physicochemical parameters in the slurry. Results of the study proved that the respective feed additive decreased ammonia emissions in the experimental unit. The addition of 2 % of zeolite to mixed feed resulted in a decrease in ammonia emission by about 33 % and a decrease in ammonium concentration in the slurry by 25 %.
