Heart rate (HR) and grazing activity of lactating cows were measured to assess the energy expenditure (EE) associated with grazing on an inclined slope. In experiment 1, the HR and movements of lactating Holstein cows grazing on an inclined slope were recorded using an HR monitor and a global positioning system (GPS). These data were used in conjunction with altitude to calculate relative heart rate (RHR : HR during grazing/HR during rest while standing) per moving inclination during grazing. In experiment 2, the moving inclination of lactating Holstein cows during grazing was measured using a GPS receiver on an inclined pasture (11.8°) and the daily EE associated with grazing was calculated with the RHR values obtained in experiment 1. In experiment 1, the HR associated during grazing and resting while standing were 92.9 and 88.0beats/min, respectively. The RHR associated during grazing was higher than during resting while standing (P＜0.05). Also, the RHR of cattle ascending inclinations greater than 8° (1.15) during grazing were higher than those of cattle ascending inclinations of 0° to 2° (1.09) (P＜0.01). No difference was observed between the RHR of cattle descending inclinations of 0° to 2° and the RHR of cattle descending inclinations greater than 2°. In experiment 2, the time budget for grazing per day was 500.2 to 584.0 min, and the percentage of cattle ascending more than 8° during grazing was 12.9 to 16.4%. The EE associated with grazing per day ranged between 306.2 and 346.3 kJ/BW^<0.75>, which was similar to the estimated EE in cows grazing on a level pasture. The inclination of a pasture therefore seemed to have no e ect on the EE associated with grazing, likely because the ascending inclination of lactating cows during grazing was less than the inclination angle of the pasture as a whole. However, it suggested that the EE associated with grazing estimated from the percentage of cattle ascending or descending and RHR was overestimated.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"1764","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHINGU, Yuko"}]},{"nameIdentifiers":[{"nameIdentifier":"1765","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MORI, Mitsuo"}]},{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"","nameIdentifierScheme":"ISNI","nameIdentifierURI":"http://www.isni.org/isni/"}]}],"familyNames":[{"familyName":"NAKATSUJI","familyNameLang":"en"},{"familyName":"中辻","familyNameLang":"ja"}],"givenNames":[{"givenName":"Hiroki","givenNameLang":"en"},{"givenName":"浩喜","givenNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"43","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9313","nameIdentifierScheme":"教員総覧","nameIdentifierURI":"https://www.rakuno.ac.jp/archives/teacher/9313.html"}],"names":[{"name":"NAKATSUJI, Hiroki","nameLang":"en"},{"name":"中辻, 浩喜","nameLang":"ja"}]},{"nameIdentifiers":[{"nameIdentifier":"1766","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KONDO, Seiji"}]},{"nameIdentifiers":[{"nameIdentifier":"1767","nameIdentifierScheme":"WEKO"}],"names":[{"name":"UMEMURA, Kazuhiro"}]}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本畜産学会"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2508/chikusan.83.47","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-907X","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_19":{"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":"新宮, 裕子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 光生"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"NAKATSUJI, Hiroki","creatorNameLang":"en"},{"creatorName":"中辻, 浩喜","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"近藤, 誠司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"梅村, 和弘"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-09-14"}],"displaytype":"detail","filename":"S-2013-49_nakatsuji.pdf","filesize":[{"value":"865.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S-2013-49_nakatsuji.pdf","url":"https://rakuno.repo.nii.ac.jp/record/565/files/S-2013-49_nakatsuji.pdf"},"version_id":"bc80a11e-a3d0-4f04-b7e6-2f4fbc95eea7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"heart rate","subitem_subject_scheme":"Other"},{"subitem_subject":"lactating cows","subitem_subject_scheme":"Other"},{"subitem_subject":"moving inclination","subitem_subject_scheme":"Other"},{"subitem_subject":"slope pasture","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"傾斜放牧地での移動傾斜角度が泌乳牛の採食時心拍数に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"傾斜放牧地での移動傾斜角度が泌乳牛の採食時心拍数に及ぼす影響"}]},"item_type_id":"2","owner":"3","path":["14"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-16"},"publish_date":"2014-06-16","publish_status":"0","recid":"565","relation_version_is_last":true,"title":["傾斜放牧地での移動傾斜角度が泌乳牛の採食時心拍数に及ぼす影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-30T02:08:41.642575+00:00"}
