Given the variety of diseases prevalent in swine production, both in the United States and abroad, it is important to understand the risks associated with organic swine production. Overall numbers for certified organic livestock remain low compared to the overall U.S. swine numbers, with approximately 12,000 animals in 2011. However, since 1992, stocks have increased dramatically, with an annual growth rate of 20 percent in total U.S. organic stock. Additionally, there are thousands of non-certified organic swine herds which are not accounted in official statistics, but where farmers still use organic production practices. Consumer demand, stemming from the larger organic agriculture movement has helped spurred growth in this industry. The overall segment, although minuscule compared to the conventional national average, still represents a strong and growing segment in U.S. pork production. The definition of organic swine according to the USDA National Organic Program (NOP), is largely unchanged: == Organic swine production prerequisites == *Animals for slaughter must be raised under organic management from the last third of gestation. Producers are required to feed livestock agricultural feed products that are 100% organic, but may also provide allowed vitamin and mineral supplements〔USDA-National Organic Program, 2013. Organic Livestock Requirements. USDA-AMS; http://www.ams.usda.gov/AMSv1.0/getfile?dDocName=STELPRDC5102526〕 *Organically raised animals may not be given hormones or antibiotics in growth promotion *Vaccines and other holistic forms of preventive management are allowed, so long as they fall within the Organic Materials Review Institute (OMRI) guidelines〔Products List, Organic Livestock; 2013. Organic Materials Review Institute, 2013. http://www.omri.org/simple-opl-search/results/Livestock%20Feed%20Ingredients〕 *Producers are not allowed to withhold treatment from a sick or injured animal; yet animals treated with a prohibited medication may not be sold as organic *All organically raised animals must have access to the outdoors; and conversely in colder climates access to indoors *Swine and livestock can be confined temporarily for reasons of health, safety, the animal’s stage of production, and soil and water quality protection * Managed organically from the last third of gestation * A description of the management practices and barriers established to prevent commingling of organic and non-organic animals in split operations with proper paperwork and list of substances used 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Risk assessment for organic swine health」の詳細全文を読む スポンサード リンク
