Thirty-four Holstein cows were categorized into three groups (Low, n = 9; Middle, n = 16; High, n = 9) based on the quartile of average daily 4% fat-corrected milk production during early pregnancy. The High group showed higher milk component production than the other groups (P < 0.05) during early and mid-pregnancy. Although most placental characteristics did not differ significantly among the groups, cows in the High group had larger individual cotyledons and fewer medium-sized cotyledons than those in the Low group (P < 0.05). Plasma amino acid concentrations of calves in the Low and High groups were significantly higher than those of calves in the Middle group, although calf birth weights were similar among the groups. Furthermore, cows in the Low group had longer dry periods than those in the High (P = 0.004) and Middle (P = 0.058) groups. This suggests that cows in the Low group may have provided more amino acids to the fetus because of low lactation and long dry periods. Conversely, cows in the High group required more energy for lactation during early pregnancy, which can reduce nutrient availability to the placenta and fetus; however, increasing individual cotyledonary sizes during late pregnancy may ensure that the same amounts of amino acids as those in cows in the Low group are supplied to the fetus, recovering the birth weights. © 2023 by the Society for Reproduction and Development.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japanese Society of Animal Reproduction (JSAR)","subitem_publisher_language":"en"}]},"item_2_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"37587048","subitem_relation_type_select":"PMID"}}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1262/jrd.2023-004","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©2023 by the Society for Reproduction and Development","subitem_rights_language":"en"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168818","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_language":"en","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":"Mashimo, Riku","creatorNameLang":"en"},{"creatorName":"真下, 陸","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ito, Sayaka","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kawashima, Chiho","creatorNameLang":"en"},{"creatorName":"川島, 千帆","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-11-22"}],"filename":"Kawashima_69_2023-004.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_5","url":{"label":"Full text","objectType":"fulltext","url":"https://obihiro.repo.nii.ac.jp/record/2000105/files/Kawashima_69_2023-004.pdf"},"version_id":"559adff8-6bc9-4262-9810-1994982195dc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Calf birth weight","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Cotyledons","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Milk production","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Plasma amino acid concentration","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Differences in daily milk production during early pregnancy alter placental characteristics and neonatal metabolic amino acid levels in dairy cows","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Differences in daily milk production during early pregnancy alter placental characteristics and neonatal metabolic amino acid levels in dairy cows","subitem_title_language":"en"}]},"item_type_id":"2","owner":"12","path":["5"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-11-22"},"publish_date":"2023-11-22","publish_status":"0","recid":"2000105","relation_version_is_last":true,"title":["Differences in daily milk production during early pregnancy alter placental characteristics and neonatal metabolic amino acid levels in dairy cows"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-02-28T03:11:13.516609+00:00"}
