Between September 9, 2008 to September 8, 2009, 260 times comprehensive surveys of piggeries were completed. These surveys focused on piggery management, actual breeding capacity, and pollution prevention processes. During this period, improvements were made in feeding site odor management, manure odor control, and dead pig odor control. For feeding site odor management: 1) six piggeries (up by 13%) started using odor inhibitor to prevent odor, and 2) one piggery (up by 2%) started using nets to reduce odor. The number of piggeries (5) using the sterilization method to control the odor did not change. For manure odor control: 1) two piggeries (up by 4%) started using odor inhibitor, and 2) one piggery (up be 2%) started using nets or covers to reduce odor. For dead pig odor control: 1) two piggeries (up by 4%) started using covers, and 2) nine piggeries (up by 18%) started using bactericide to control odor. There was no change in the number of piggeries that neutralized odor in the sewage treatment facility.
The project also finished 102 site examinations during the same time period. 86 of them were routine examinations and the remaining were auditing examinations. According to the examination results, nine piggeries did not pass the standard guidelines. These nine piggeries were requested to increase the frequency of odor prevention treatment (for example, increasing the spray frequency of the odor inhibitor). Three follow-up audits were conducted in January, April, and June, 2009, and all showed that these nine piggeries had met the standard.
In addition to the improvements mentioned above, this project also helped 6 piggeries under the “enviromental improvement consulting” program. The test results showed that the program helped the piggeries to reduce odor and had a good impact on the surrounding area.
