HYGIENIC ASSESSMENT OF MICROCLIMATE INDICATORS IN THE MAIN DEPARTMENTS OF THE LIVESTOCK COMPLEX

Assessment of microclimate indicators in the main buildings of livestock complexes. The main microclimate indicators in livestock complexes are indoor temperature, relative air humidity, concentration of ammonia, carbon dioxide and hydrogen sulfide, and air movement speed. Control and management of microclimate parameters in livestock complexes is an important factor in ensuring high productivity of animals. At the moment, in our country, there are no comprehensive control systems of microclimate parameters in livestock complexes, ventilation systems are controlled by one or two parameters. The normalized parametric indicator is the concentration of ammonia in the reservoir. As a result of various factors, ammonia concentration varies by 1.5-2.0 times according to the size of the building. Eliminating this deficiency requires the organization of local ventilation with the supply of fresh air to the most gassed areas of the room. The statistical analysis of the obtained laboratory data showed that the average value of ammonia concentration inside closed buildings is 0.733 mg / m ³, standard deviation s = 0.134 mg / m³, the coefficient of variation is 18.3%.
