This study is aimed at assessing the impact of microclimatic parameters in cowsheds for dairy cows on milk productivity during the winter period in the Semey region. The indoor microclimate is one of the factors that directly affect the physiological condition and productivity of livestock. The main indicators recorded during the study included air temperature, relative and absolute humidity, carbon dioxide (CO₂) concentration, ammonia (NH₃) concentration, and the temperature–humidity index (THI).
The research was conducted in January–February 2024 at a livestock facility near the city of Semey, in a cowshed designed for 100 cows. Measurements were taken at ten points at two different heights (0.2 m and 1.5 m). According to the results, the air temperature inside the cowshed dropped to as low as -2.8 °C, while the relative humidity reached 92%. Absolute humidity was recorded at 7.8 g/m³, and the THI index rose to 62 units. The CO₂ concentration reached 2700 ppm, and the NH₃ concentration was recorded at 36 ppm.
Significant deviations of these indicators from the permissible norms were found to negatively affect the physiological state of the cows, contributing to a 10–18% decrease in milk productivity. Based on the study results, it is recommended to use infrared heaters, mechanical ventilation systems, and automatic climate control systems to stabilize the indoor microclimate. This research provides scientifically based recommendations for maintaining and improving dairy cow productivity during the winter period.
