Goats initially housed in thermoneutral environment (20°C,80%) were fed once daily with equal amounts of sudan grass hay (2cm-cut) in both environments. The digestibilities of crude protein and neutral detergent fiber (NDF) were higher in heat exposure (P<0.05). The concentration of VFA, particularly n-butyric acid, in the rumen tended to increase in beat exposure. Also, the passage rate of feeds through the digestive tract of goats tended to decrease. The amplitude and frequency of contract in internal pressur of the rumen were higher in heat exposure (P<0.05).","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"日本畜産学会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4647"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1346-907X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00195188"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"日本畜産学会報"},{"subitem_1522650068558":"en","subitem_1522650091861":"Animal Science Journal"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueNumber":"8","bibliographicPageEnd":"J263","bibliographicPageStart":"J258","bibliographicVolumeNumber":"71"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"4.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2002462/files/4.pdf"},"version_id":"a86cf0af-1825-4db8-bb6b-61035c9aff53"}]},"item_title":"暑熱暴露がヤギの消化管通過速度と第一胃収縮運動に与える影響","item_type_id":"15","owner":"1","path":["1642838338003","1642838407312"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-02-19"},"publish_date":"2008-02-19","publish_status":"0","recid":"2002462","relation_version_is_last":true,"title":["暑熱暴露がヤギの消化管通過速度と第一胃収縮運動に与える影響"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-08-03T05:34:53.236922+00:00"}
