Microclimate Indices Dynamics in Sections for Non-pregnant and Pregnant Sows

Abstract

In transition and winter period of the year usage of mechanical ventilation system allows to decrease relative humidity and bacterial pollution of air in sections for non-pregnant and pregnant sows management. The thermal rehabilitation of walls and floors and natural ventilation in sections for pregnant sows management ensured the perfect temperature levels in cold and transition periods, however, because of low mobility of the air flow there was and excessive humidity level as well as ammonia pollution of air.
