Therefore, it remains unclear whether these pig groups\nare nomadic or semi-nomadic in different study areas. Nobody knows who\nkeeps these pigs, how they are cared for and controlled, or for what purpose\nthey are being kept. Many anthropological studies of nomadic pastoralism\nhave been made, with the noteworthy exception of such pigs: a lone study of\npigs in Bangladesh is available in the literature. To investigate the actual conditions\nof this type of nomadic pig husbandry, the author conducted ethnological\nfield research during the dry season (December 2007–February 2008) and\nthe rainy season (July–August, 2008). First, nomadic pig herds were sought in\nthe Dhaka area, Tangail District, and Gazipur District in the Bengal delta of\nBangladesh. The herds were then followed and observed to discover how they\nfed and their routes of movement.\nIn Bangladesh, pigs are raised by humans. They are seasonally nomadic\nwhile their owners seek grazing land and fodder for them. Each herd studied\nincluded approximately 100–200 pigs. The herds move over vast areas while\nseeking food in cultivated field lands. The movements very according to the\nseasons, the routes chosen according to food availability. Regarding the daily\nroutine of nomadic pig husbandry, pig keepers depart from their camp in the\nmorning and return to it in the evening. While herding their pigs, they diligently\nprevent the pigs from entering cultivated fields. Each herd occupies a\nwide area while seeking food in the open fields. By calling the pigs, the keepers\ncan reduce the area that the animals occupy: that is to say the pigs pay\nattention to the commands of their handlers.\nThe route of movement of the pigs and the seasonal change of land use\nare illustrative. Pig groups moved according to the season, depending on the\navailability of food resources. During the rainy season (June–September), they\nare able to live near flooded rivers. In years with large-scale flooding, they\nare reportedly kept in the forest, where they can eat trees roots. During thedry season, they are kept in cultivated fields after harvest. By digging in the\nsoil, pigs are able to eat some plants that are considered noxious weeds by the\nfarmers. The pigs can also eat rice grain remaining in paddy fields after harvest.\nHowever, when farmers began using a field for wheat and maize, the\npigs had to be moved to other areas.\nThe seasonal change in feeding resources was as follows. During the\ndry season, wild plants such as taro were the most important feeding resource\nsupporting nomadic pig husbandry. Crops were also used. During the rainy\nseason, earthworms were used as fodder. I observed cases of pigs kept in rubbish\ndisposal areas for a few months near the main road of the city. In this\ncase, two keepers made a camp and cared for their pigs. The rubbish site was\nconstantly supplied from the city with kitchen refuse, which the pigs were\nkeen to eat. In February 2008, two handlers were keeping their pigs in the\nsame refuse area. However, in August 2008, they lost this resource because a\nlocal government office prohibited use of the land as a rubbish dump. No further\ninformation relating to how they cared for their pigs was obtainable after\nthat.\nNomadic pig pastoralism in Bangladesh depends on the seasonal use of\nnatural resources and on less-seasonal kitchen refuse when available. The significance\nof this case study, for interactions between pigs and humans in tropical\nmonsoon Asia, will be explored further in the near future.","subitem_description_type":"Abstract"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15021/00003860","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立民族学博物館"}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00091943","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-180X","subitem_source_identifier_type":"ISSN"}]},"item_9_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"池谷, 和信"},{"creatorName":"イケヤ, カズノブ","creatorNameLang":"ja-Kana"},{"creatorName":"Ikeya, Kazunobu","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-11-19"}],"displaytype":"detail","filename":"KH_036_4_003.pdf","filesize":[{"value":"8.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KH_036_4_003.pdf","url":"https://minpaku.repo.nii.ac.jp/record/3868/files/KH_036_4_003.pdf"},"version_id":"d552ed0b-6311-4f20-8247-362c6d1965c5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"遊牧","subitem_subject_scheme":"Other"},{"subitem_subject":"ブタ","subitem_subject_scheme":"Other"},{"subitem_subject":"餌資源","subitem_subject_scheme":"Other"},{"subitem_subject":"群れ管理","subitem_subject_scheme":"Other"},{"subitem_subject":"ベンガルデルタ","subitem_subject_scheme":"Other"},{"subitem_subject":"nomadic pastoralism","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pig","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"feeding resources","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"herds management","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Bengal delta","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"バングラデシュのベンガルデルタにおけるブタの遊牧","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"バングラデシュのベンガルデルタにおけるブタの遊牧"},{"subitem_title":"On Nomadic Pig Pastoralism in the Bengal delta of Bangladesh","subitem_title_language":"en"}]},"item_type_id":"9","owner":"17","path":["359"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-30"},"publish_date":"2012-07-30","publish_status":"0","recid":"3868","relation_version_is_last":true,"title":["バングラデシュのベンガルデルタにおけるブタの遊牧"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T19:20:16.721609+00:00"}
