순천시의 폐사가축 처리실태에 관한 연구 = Farm Animal Mortality Management Practices in Sunchon-si

국문 초록 (Abstract)

축산업의 대규모 전업화로서 폐사가축이 급증되어서 대기, 수질, 토양, 지하수 등의 환경오염 및 쥐. 파리. 까마귀 등의 썩은 고기를 좋아하는 위해동물 번식으로 인하여 자연환경이 오염되어가고 있다. 전라남도 순천 지역 중심의 축종별 호당 연간평균 사육두수는 양계농가 251,000마리, 양돈농가 2,600두, 한우농가 142두 및 낙농가 92두 등 이었으며, 호당 연간추정 폐사가축 발생량은 양계농가 0.46톤, 양돈농가 15.32톤, 한우농가 0.36톤 및 낙농가 1.33톤 등이었다. 순천지역 축산농가의 연간 추정 폐사가축 발생량은 2,754톤 이였으며, 특히 양돈농가 폐사가축 발생량은 1,287톤으로 전체발생량의 47%를 차지하였다. 폐사가축 처리방식은 산지와 과수원 등에 매몰처리 (42%)와 축분에 투기처리 (36%)가 대부분 (78%)이며, 개별농가 사정에 따라서 렌더링, 간이소각, 침지소화 및 사체처리기 등이 활용되었다. 폐사가축처리시설 선정은 매몰처리로 발생하는 수질 및 대기오염, 위해동물 발생, 질병확산 위험 등이 없고, 처리비용이 다른 방법보다 저렴한 폐사가축 퇴비화시설 도입이 필요하였다.

Disposal methods of managing carcass in Korea livestock production systems include burying, digesting, rendering, carcass dumping to manure pile, dead animal disposer and mini-incinerator. Burying was usually the most practical method of carcass disposal in our livestock farms. Burying, carcass dumping to manure pile, dead animal disposer and mini-incinerator may have environmental regulatory and economic liabilities when used as a means of carcass disposal. In many cases in this survey, these disposal methods offer a poor choice for the producer due to individual site conditions, geology, cost, air emissions, rendering plants. A survey questionnaire that addressed the issues to livestock producers was prepared. The questionnaire addressed two main topics as follows: 1) types of livestock and generation amounts of carcass 2) Number of breeding animals and disposal methods of livestock mortality. A total of 36 livestock producers were interviewed. The results of obtained in this survey were summarized as follows: The number of breeding poultry, swine, beef cow and dairy cow was 251,000, 2,600, 142 and 92 heads per year and the generation amounts of annually carcass was 0.46, 15.32, 0.36, 1.36 tons per year of each poultry, swine, beef cow and dairy cow farms, respectively. The disposal methods of carcass were burying (42%), carcass dumping to manure pile (36%), rendering (8%), incineration (6%), digesting (6%), carcass disposer (2%), respectively. These results can be used as basic information to establish the standard of carcass composting facility.
