The purpose of the work is to study the effect of the type of room with brickwork and attic floors on the formation of microclimate indicators, productivity and behavior of pigs. Research methods - zootechnical, biometric, analytical. During the reporting period, analytical data were obtained on space-planning solutions of the pigsty and its thermal characteristics. It is shown that the total specific weight of the building fences per unit volume is 1.76 cwt/m3. The brick room had a 33.5% higher total specific mass of fences compared to reinforced concrete of three-layer panels. Regarding the action of the law of thermodynamics, this means that it was characterized by better thermal inertia. A significant positive relationship has been established between the ambient air temperature and the pigsty with masonry walls in winter and spring, with correlation coefficients of 0.47-0.56 *** and in summer and autumn respectively 0.55-0.47 *** and between relative humidity of the environment and the pigsty in the winter and spring, with correlation coefficients of 0.47-0.56 *** and in the summer and autumn respectively 0.55-0.47 ***. It was determined that when the ambient air temperature changed by 1 ° C, it reliably changed in the same direction indoors in winter and spring, by 0.21-0.31 *** ° C, respectively, and in summer and autumn, by 0.21 and 0, respectively. , 30 *** 0С, according to calculations of direct regression coefficients. Due to convection of heat or cold through the walls and ceiling, their internal surface temperature fluctuated in the circadian rhythm in the winter by 12.9%, in the spring and autumn by 9.3% and in the summer by 9.6% and depended on the thermal resistance of the fencing and values of temperature, direction, speed and relative air humidity of the environment. With an average daily temperature and relative air humidity in the room at 9.5 ° C and 87.3% in winter and 26.7 ° C and 70.3% in summer, a decrease in the average daily gain of pigs was found to be 25.4%, respectively (td = 4.06) and 12.2% (td = 2.61), according to the norms of feeding up to 550 grams. It was established that the planning and constructive solution of the pigsty with brick walls and attic floors with a natural ventilation system is characterized by insufficient air exchange and energy efficiency of the building envelope in the winter and summer periods. The calculation of the economic efficiency of pork production in an unheated room with masonry walls and attic floor suggests that on frosty days of winter and hot days of summer periods, productivity losses average 3.66 and 1.68 kg of weight gain per head per month or in cash equivalent of 109.8 and 50.4 hryvnia.
