Аннотація: According to the results of the conducted studies of the microclimate of the reconstructed livestock buildings, it was first proved that the optimal way to keep cows in the dry period is untethered in a separate section with combiboxes, which makes it possible to comply with hygienic requirements, increases the milk production of cows after calving by 15-19% and the body weight of newborn calves by 11.2%. It is established that untethered keeping of dry cows in a separate isolated section equipped with combiboxes or tethered in a separate isolated section provides optimal air temperature values, it helps to reduce the level of carbon dioxide by 0.06-0.08%, relative humidity - by 16-20%, microbial air pollution - by 2.1-2.3 times, the level of industrial noise - by 6.5-7.9 times, improves the efficiency of use of production areas and internal equipment of the premises.
