A regression equation for the estimation of the temperature conditions in animal houses with thermally insulated and uninsulated constructions and closed and opened walls are developed. The equation basis is the balance between the heat and the water vapour, and experimental data. The carry out the analysis of the temperature conditions of various insulation cattle houses. There is accepted, that one animal mass - 350 kg, for one animal belongs 3.0 and 4.5 Square m of total space of the floor, width of the premises - 15 m; the heat transmission coefficient of the roof - 0.13-3.0 W/(Square m K), that of the walls - 0.4-3.0 W/(Square m K); the straw bedding. In order to prevent the condensation on uninsulated surfaces of the house, it is necessary to obtain a temperature difference between the inside and outside air equal to 5 deg C, when the outside temperature is from 0 deg C till minus 20 deg C.
