Digital images around the rib-eye area at the 6th and 7th rib of 1，543 Japanese Black (JB) and 532 crossbred (CB) steers were taken by the photographing equipment for beef cross sections at a meat processing plant in Hokkaido. Ratio of marbling area to rib-eye area (FATPER)，overall coarseness of marbling (O_COARSE)，coarseness of the largest marbling particle in rib eye (M_COARSE)，ratio of minor and major axis of rib eye (MM_RATIO)，and complexity of rib-eye shape (COMP) were calculated by image analysis. The carcass traits considered were carcass weight，rib eye area， rib thickness，subcutaneous fat thickness， BMS number, BCS grade and BFS grade. Covariates in each mathematical model were only carcass traits (Model 1)，carcass traits and image analysis traits without M_COARSE (Model 2)，and carcass traits and image analysis traits without O_COARSE (Model 3). Ranges of determination coefficients of these models were 0.799 to 0.825 in JB and 0.784 to 0.792 in CB. Standardized partial regression coefficients (SPRC) of BMS number in JB and CB were the highest in Model 1 with the values of 0.570 (JB) and 0.407(CB). Effects of FATPER were the highest in Model 2 and 3. SPRC of O_COARSE and M_COARSE were -0.079 and -0.040 in JB，-0.090 and -0.079 in CB， respectively. This result indicates that rough marbling in the rib eye is an undesirable factor in the determination of carcass value in Japan. Similar SPRC were recognized on COMP with values of -0.033 in JB and -0.045 in CB.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本畜産学会"}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本畜産学会","subitem_rights_language":"ja"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00195188","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346907X","subitem_source_identifier_type":"ISSN"}]},"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":"岡本, 圭介","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Kuchida, Keigo","creatorNameLang":"en"},{"creatorName":"口田, 圭吾","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{},{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Kato, Takayuki","creatorNameLang":"en"},{"creatorName":"加藤, 貴之","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"鈴木, 三義","creatorNameLang":"ja"}],"nameIdentifiers":[{},{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Miyoshi, Shunzo","creatorNameLang":"en"},{"creatorName":"三好, 俊三","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":"2018-01-30"}],"displaytype":"detail","filename":"1925.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1925.pdf","url":"https://obihiro.repo.nii.ac.jp/record/258/files/1925.pdf"},"version_id":"fd5bbc70-dacb-4c92-b978-11dc8ef6f693"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Japanese Black","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Carcass unit price","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Image analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Marbling","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"枝肉形質および画像解析形質が牛枝肉価格に与える影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"枝肉形質および画像解析形質が牛枝肉価格に与える影響","subitem_title_language":"ja"}]},"item_type_id":"2","owner":"12","path":["5"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-03-29"},"publish_date":"2007-03-29","publish_status":"0","recid":"258","relation_version_is_last":true,"title":["枝肉形質および画像解析形質が牛枝肉価格に与える影響"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-05-13T02:35:38.103686+00:00"}
