This study was conducted to derive preliminary inspection items for livestock odor management using field survey and expert consultation records prepared during the 2016 regional livestock odor improvement pilot project. The study covered 48 pig farms in Goseong, Yeongcheon, Cheonan, Nonsan, and Jeongeup. Management problems, improvement opinions, technical conditions, and needs for effect verification were extracted from the records and analyzed by qualitative content analysis. Similar expressions were integrated and classified into four management domains and 13 detailed items. Twenty-seven individual records and three shared records, a total of 30 independent consultation records, were used for the frequency analysis. Operation, inspection, maintenance, and effect verification were addressed in 100.0% of the records, composting and liquid-manure treatment management in 96.7%, and enclosure of odor-generating facilities and air collection, scrubbing, and deodorization in 93.3% each. Biocurtain management was addressed in 73.3% and cleaning and farm sanitation in 70.0%. These percentages indicate how often each management item was reviewed in the consultation records and do not mean that the same problems occurred at the same percentage of farms. Preliminary surveys mainly showed demands for liquid-manure circulation systems, biocurtains, microbial products, and BM-activated water. In contrast, expert consultations reviewed sludge removal, storage capacity, enclosure of manure-treatment facilities, exhaust-air collection, operation conditions, and effect verification before applying those technologies. Shared records for the Nonsan pig-farming complex and the Jeongeup municipality project were treated as common management opinions and not as independent judgments for each farm. Because the data were prepared in 2016, the items derived in this study should be used as basic data for standardizing field records and preparing a current inspection checklist rather than as a tool for directly evaluating current farms. Further studies are needed to update the items for current facilities and technologies and to verify content validity, inter-rater reliability, and field applicability.
