Zoohygienic investigations of microbiological and dust contamination of air were carried out in two types of cowsheds designed for fatstock on a state farm "S" in winter and summer 1977. The investigations were carried out in buildings of Opole and Bialystock types. The buildings differed in building material used for construction and the designs of the sewage systems. In the air the total number of bacteria was determined as well as the number of hemolyzing bacteria, Escherichia coli, the number of fungi and the degree of dustiness
