| Abstract: |
In order to study the dependence of the microclimate indicators in the fattening building on the frequency of drainage of manure pits and the external temperature, an experiment was conducted in the production conditions of the pig complex. Four groups of pigs with 2,500 heads in each group were selected for the experiment. In the first control group, the draining of the manure pits took place before the animals were placed for fattening and as the pits were filled. In the experimental groups, the pits were drained before planting and every 14 days in the second group, every 21 days in the third group, and every 28 days in the fourth group. Gas content and air humidity indicators were measured every third day at 07:00, 13:00 and 18:00 in all four buildings at 6 points in different equally spaced pens of the fattening building under the ventilation valves. It was found that the average concentration of hydrogen sulfide and ammonia depended on the frequency of emptying the pits in the building, while the content of carbon dioxide did not depend on it. The content of hydrogen sulfide and ammonia depended on the frequency of emptying manure pits, and the content of carbon dioxide did not depend. At the same time, the content of ammonia and carbon dioxide depended on the external temperature, while the content of hydrogen sulfide did not depend on it. The relative humidity in the fattening building increased with a decrease in the frequency of draining pits, however, it did not depend on the external temperature. [ABSTRACT FROM AUTHOR] |
