LEVEL OF HARMFUL GASES IN AIR OF THE SECTION FOR FARROW AT DIFFERENT SEASONS OF A YEAR AND CONDITIONS OF MICROCLIMATE
Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 2, Issue 2
Abstract
The aim of the research was to determine the level of ammonia and hydrogen sulfide in air of premise for sows under different conditions of creating microclimate depending on the season and temperature in sections and compare the production efficiency of two system of air giving and its degree of purity. For study it has been taken two premises with different ventilation system. The comparative analysis of the data about the content of ammonia and hydrogen sulfide in the first and second premises showed that in the second premise where in all seasons of a year air was given through wall valves the level of ammonia was in 2.4 ... 30.3 times significantly (P <0.01 ... 0.001) higher than in air of the first premise. The concentration of hydrogen sulfide in air of the second premise was also significantly higher in 3,7..13,1 times (P < 0.001) than air in the first premise. The oxygen content in air of the second premise, except the winter period, was significantly (p <0.05 .. p <0.005) lower than in the first premise.
