A sty or pigsty is a small-scale outdoor enclosure for raising domestic pigs. It is sometimes referred to as a hog pen, hog parlor, pigpen, pig parlor, or pig-cote. Pigsties are generally fenced areas of bare dirt and/or mud. "Sty" and "pigsty" and "pigpen" are used as derogatory descriptions of dirty messy areas. There are three contributing reasons that pigs, generally clean animals, create such a living environment: * Pigs are voracious eaters and will eat all the plants in the enclosure until there is nothing left to control erosion. * The pig is a rooting animal and will dig for food in the enclosure, further disturbing the soil. * Pigs do not regulate temperature by sweating which means that they must be provided with water or mud in which they can control their own body temperature. A large-scale enclosure for raising pigs is generally called a hog lot. Unlike a sty which would be found on a mixed farm, a hog lot is usually a dedicated facility. == Family farm hog pen == The family hog pen was a small-scale system of pig farming vastly different from the modern American hog farm. Modern intensive hog farms in the United States have an average of about 2,000 hogs, and large farms raise tens of thousands of hogs. Hog pens were found on family farms of the early 1900s, although backyard pig farming may still occur. In this article the words "hog" and "pig" are used interchangeably. Family hog pens enclosed just a few hogs to provide year-round meat for the table. Before refrigeration, some family farms depended on pigs as a primary source of meat and shortening (lard) for year-round food. Farms which had tenant families might have several hog pens. 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「sty」の詳細全文を読む スポンサード リンク
