The study deals with the influence of external environmental factors on pig production. It is safe to assume that with
common management and corresponding quality of buildings, technology and other inputs, the microclimate is an important
factor in breeding efficiency and health in pigs. Correct parameter setting of the living environment of stables, based on the
temperature curves and relative humidity (RH), causes temperature-humidity animal welfare, which significantly affects the
production yield.
It has been shown that controlled stable microclimate, according to the temperature and RH, significantly increases the live
weight (P≤0.05) in growers, as well as their growth intensity (P ≤ 0.01). It was also demonstrated that the selected production
traits in pigs of both sections (with controlled and uncontrolled microclimate) are influenced by the current season
