Microclimate parameter dynamics in pig housing using the biodestructor Sanaero

Among the various unpleasant gases that are formed and accumulated in the rooms for intensive pig growing ammonia and hydrogen sulfide are considered to be the most dangerous. These gases are key indicators of environmental safety and comfort of animals and workers. The purpose of this study was to determine changes in the concentration of ammonia and hydrogen sulfide in the air of pigs for feeding pigs when using the microbial preparation developed by us for the destruction of Sanaero pus. It was established that the highest concentration of ammonia in the air of boxes was recorded on the ninth day in the test samples – 56.7 ±3.9 mg/m3 and 2.1 times (P < 0.05) less concentration (25.8 ± 1.7 mg/m3) in the premises, which were added to the pump. In the future, a gradual decrease in the concentration of ammonia in the control and experimental premises, so on the 17th day, the content of ammonia was 25.1 ± 1.6 mg/m3 in the air in control and 11.8 ± 0.8 mg/m3 in the air of the experiment. This indicates more active release of gaseous ammonia from pus in the air in control and more slowly in the experiment using the Sanaero biodestructor. It is established that the treatment of manure in the piggies with a biodestator Sanaero allows to reduce the formation of hydrogen sulfide in the air of boxes, about 2 – 3 times, comparing with control boxes at ambient temperatures + 20 – +25 °C. Therefore, during the production use of the Sanaero biodegrade developed by us, there is a significant positive correlation to reduce the secretion of ammonia and hydrogen sulfide into the air of the pigmen, comparing with the premises in which the biodegradist was not used.
