Its increase in the area where the sow is located by 4.8 ºС (from the recommended norms) caused a deterioration in their appetite, milk production and milk yield and, as a result, reduced the growth intensity of piglets. The increase in air temperature in the area of the piglets' den by 2.4 ºС (from the established norms) contributed to their intensive growth. During the suckling period of raising, piglets of the experimental group gained an average of 0.47 kg more, and their average daily gain was 16.21 g higher than that of their peers from the control group. Lowering the air temperature in the machines for keeping animals by 1.2 and 0.6 ºС in the summer and by 1.2 and 0.5 ºС in the autumn periods of the year in the experimental groups ensured better indicators of fattening and meat qualities of pigs. Thus, during the fattening period in summer, compared to the control, the average daily gain of fattening pigs was greater by 64 and 41 g, and in autumn by 54 and 38 g, respectively. Relative humidity and air movement speed were within the recommended norms and did not affect the breeding and productive qualities of the animals.
