The possibility to predict on these carcass trait estimates 40 months of age by using multiple regression equations which adopted carcass estimates and body measurements obtained 20 months of age. Relationships between ultrasonic estimates of carcass traits of bulls of 40 months of age and carcass measurements of fattening progeny steers were studied. \nThe mean increase of ultrasonic estimates during twenty months after 20 months old were -0.4~-0.2mm (the smaller growth rate group : A group) or 2.6~2.7mm (the larger growth rate group : B group) for FT, 8.5cm^2 (A group) or 12.5~13,2cm^2 (B group) for MLTA and 0.7~1.0 (A group) or 1.5~2.0 (B group) for MA, respectively.\nBy using multiple regression equations the rations of contribution for predicting carcass traits estimates of bulls on 40 months old were 75.9~87.4% (A group) or 70.6~84.2% (B group) for FT, 88.5~91.1% (A group) or 67.2~75.1% (B group) for MLTA and 912~95.2% (A group) or 65.2~71.4% (B group) for MA, respectively.\nRank and simple correlation coefficients between carcass trait estimates of bulls on 40 months old and carcass trait measurements of progeny steers after fattening were -0.229~0.176, and all of these were not significant.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10007_description_14":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"この研究は「伊藤記念財団」の助成を受けて行われました。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10007_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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"hrd_19.pdf","filesize":[{"value":"298.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://miyazaki-u.repo.nii.ac.jp/record/4797/files/hrd_19.pdf"},"version_id":"0a2e390e-3bd8-463b-8a25-b55edfb52ea0"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_researcher":{"attribute_name":"研究代表者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"https://isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"原田, 宏","creatorNameLang":"ja"},{"creatorName":"ハラダ, ヒロシ","creatorNameLang":"ja-Kana"},{"creatorName":"Harada, Hiroshi","creatorNameLang":"en"}],"familyNames":[{"familyName":"原田","familyNameLang":"ja"},{"familyName":"ハラダ","familyNameLang":"ja-Kana"},{"familyName":"Harada","familyNameLang":"en"}],"givenNames":[{"givenName":"宏","givenNameLang":"ja"},{"givenName":"ヒロシ","givenNameLang":"ja-Kana"},{"givenName":"Hiroshi","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3318","nameIdentifierScheme":"WEKO"}]}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"肉用種雄牛の産肉能力の早期推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"肉用種雄牛の産肉能力の早期推定","subitem_title_language":"ja"},{"subitem_title":"Early Prediction on Perfomance of Meat Production in Live Beef Sire","subitem_title_language":"en"}]},"item_type_id":"10007","owner":"5","path":["74","58"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-06-21"},"publish_date":"2020-06-21","publish_status":"0","recid":"4797","relation_version_is_last":true,"title":["肉用種雄牛の産肉能力の早期推定"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2024-12-06T07:07:00.953339+00:00"}
