ABSTRACT:
The purpose of the present study was to evaluate the microclimate in the beef cattle barns and investigate dependencies between some microclimatic indices. The study showed that there were different levels of microbial pollution in various cattle barns. Highest concentration of microorganisms was in the air of smallest (80 places) insulated beef cattle barn: total bacterial count was 114,73 thous. CFU m-3, E. coli count 17,27 thous. CFU m-3, moulds count 6,55 thous. CFU m-3. Smallest concentration of microorganisms was in the air of uninsulated dairy barn: total bacterial count was 48,06 thous. CFU m-3, moulds count 1,00 thous. CFU m-3. Concentration of microorganisms in the air of cattle barns strongly related with animal density and dust concentration in the air. Concentration of ammonia and carbon dioxide mostly depended on air velocity in the cattle barns.
