Results of researches are stated according to efficiency of various ways warmed pigs. It is established, that application of warmed panels allows forming more comprehensible conditions of rest for pigs. Thus within 31 days at 137,13 kw – hour or the charge of the electric power on heating of one jack of pigs is reduced to 68,48% in comparison with use of lamps of infra-red radiation without essential decrease of growth rate and safety of young growth

The researches were carried out in 2005-2006 at swine complex Zazerye of Mozyr region (the Republic of Belarus), that counts 54 thousand heads annually. The aim of the research is to develop perfect ventilation systems in reconstructed buildings for farrow and weanlings growing, that will provide resource saving and comfort conditions for animals. It is determined that providing perfect microclimate in buildings and energy spends cut for this climate creation in winter period is possible if technological qualities of fence constructions is higher from 0,97 to 2,5 m2 and natural ventilation is used. Microbe semination of the buildings for farrow and weanlings growing at this periods is 1,4-3,6 times lower. During the summer the combination usage of natural and imitation air ventilation is necessary
