The use of linear regression had a high prediction accuracy (93–96%) of the temperature-humidity index (THI) in NPs of different types during the summer heat. Multiple correlations between temperature and humidity conditions and animal productivity were significantly higher in transitional periods of the year. In spring, the negative correlation was 0.4–0.8 between the components of milk (protein and fat content) and the state of the air environment (temperature, relative humidity, and TNI); in the autumn period it was 0.6. The percentage of influence of seasonal fluctuations in weather conditions on production can be up to 60%. During long-term moderate heat stress, a significant decrease in the content of dry skimmed milk residue, mass fraction of fat and protein was observed in dairy cows. The mass fraction of lactose and minerals tended to increase. In general, the indicators of milk quality were within the physiological norm. It follows from this that the animal's body used internal compensatory mechanisms to normalize the composition of milk. The use of 16 frame beehives makes it possible to increase the number of worker bees to the main honey collection, which ensures a 34.3% increase in honey market productivity and a 17.1% increase in gross honey productivity. In the winter period, weakening of families was observed in the experimental group by 5.1% less than in the group with older mothers. When calculating feed costs per street, families in the experimental group consumed less feed than in the control group: in the winter period by 0.02 kg or 0.7%.
