Hardjo の不顕性感染が潜在的に乳牛の生産性を低下させる1要因となり得ることが明らかとなった。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人 日本獣医師会","subitem_publisher_language":"ja"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00191857","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04466454","subitem_source_identifier_type":"PISSN"}]},"item_2_subject_21":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"649","subitem_subject_scheme":"NDC"}]},"item_2_version_type_20":{"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":"室矢, 武則","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{}],"affiliationNames":[{}]}],"creatorNames":[{"creatorName":"Aoki, Takahiro","creatorNameLang":"en"},{"creatorName":"滄木, 孝弘","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-02-19"}],"displaytype":"detail","filename":"repo202002-01.pdf","filesize":[{"value":"3.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"fulltext","url":"https://obihiro.repo.nii.ac.jp/record/4635/files/repo202002-01.pdf"},"version_id":"38c814cf-4d9c-44e9-baa8-268635a50b0f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Leptospira 血清型 Hardjo","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"不顕性感染","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"繁殖成績","subitem_subject_language":"ja","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":"北海道の1酪農場におけるLeptospira血清型Hardjoの不顕性感染と繁殖成績の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北海道の1酪農場におけるLeptospira血清型Hardjoの不顕性感染と繁殖成績の関係","subitem_title_language":"ja"}]},"item_type_id":"2","owner":"12","path":["5"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-02-19"},"publish_date":"2020-02-19","publish_status":"0","recid":"4635","relation_version_is_last":true,"title":["北海道の1酪農場におけるLeptospira血清型Hardjoの不顕性感染と繁殖成績の関係"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-02-28T03:02:17.995785+00:00"}
