This low regrowth rate leads to a decline in TY vegetation because of the invasion of weeds and results in a need of more areas of pasture in limited farmland for dairy farming. Introducing OG into farms may help resolve these problems ; however, information on OG that is only used for grazing is scarce. This study was conducted to evaluate the yield, nutritive value, and persistency of OG (cv. Okamidori) pasture for five consecutive years after its establishment in central Hokkaido located in northern Japan (42° 59′ N, 14° 124′ E ; 90m above the sea level). The experimental plot was 60 m^2, and four heifers were grazed in the plot for approximately an hour whenever the plant height reached 25cm. As a control plot, the same area of TY pasture was established, and four heifers were grazed whenever the plant height reached 30cm. Yields of the OG plot were over 9t DM/ha from the first to fourth year after establishment, and it seemed that grazing for more than seven times grazing was possible during the grazing season. The average utilization percentage of the OG herbage mass was 69.5%. The nutritive value and palatability of the herbage was not inferior to that of the other grass species ; e.g., TY, meadow fescue (Festuca pratensis Huds.), and perennial ryegrass (Lolium perenne L.). Because the botanical composition of OG and TY in the OG and TY plot was 79% and 56%, respectively, in the fifth year, it was said that the persistency of OG pasture was greater than that of TY pasture in central Hokkaido. In contrast, frequency of bare land in the OG plot tended to exceed that of bare land in the TY plot according to year. It was concluded that more study that focus on increasing the density of OG pasture by managing lower plant heights and on conserving the pasture are required.\n","subitem_description_type":"Abstract"},{"subitem_description":"将来的に育成される高糖含量オーチャードグラス（OG）の利用法開発に先立ち, 北海道中央部において中生品種「オカミドリ」を一定草高で放牧専用利用した場合の収量, 栄養価および永続性について, チモシー（TY）を対照として, 5年間にわたり評価した。試験区は60m2とし, 草高が25cm に達するごとにホルスタイン種未経産牛4頭を約1時間放牧した。その結果, 造成後利用1-4年目の収量は 9tDM/ha 以上を示し, 7回以上の放牧利用が可能と考えられた。放牧回次ごとの平均利用率は69.5％を示し, 嗜好性に問題はなく, 栄養価や成分も TY など他の高栄養草種と比較して遜色なかった。利用5年目における試験区の草種構成割合は OG が79％を占め, TY よりも永続性に優れることが確認されたが, 利用年次により裸地の頻度が高まる年が認められた。今後は, 放牧採草兼用利用条件や密度の向上が期待できるより低い草高管理下での特性を評価する必要が認められた。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001392","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業・食品産業技術総合研究機構 北海道農業研究センター"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00001392","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-8117","subitem_source_identifier_type":"ISSN"}]},"item_10002_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":"須藤, 賢司"},{"creatorName":"スドウ, ケンジ","creatorNameLang":"ja-Kana"},{"creatorName":"SUDO, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"池田, 哲也"},{"creatorName":"イケダ, テツヤ","creatorNameLang":"ja-Kana"},{"creatorName":"IKEDA, Tetsuya","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"梅村, 和弘"},{"creatorName":"ウメムラ, カズヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"UMEMURA, Kazuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-12"}],"displaytype":"detail","filename":"harc_report_No202p13-20p.pdf","filesize":[{"value":"744.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"harc_report_No202p13-20p.pdf","url":"https://repository.naro.go.jp/record/1427/files/harc_report_No202p13-20p.pdf"},"version_id":"19c47f68-2df7-40ab-8ab8-36f0dceb2d9d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"永続性","subitem_subject_scheme":"Other"},{"subitem_subject":"栄養価","subitem_subject_scheme":"Other"},{"subitem_subject":"オーチャードグラス","subitem_subject_scheme":"Other"},{"subitem_subject":"収量","subitem_subject_scheme":"Other"},{"subitem_subject":"放牧.","subitem_subject_scheme":"Other"},{"subitem_subject":"grazing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"nutritive value","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"orchardgrass","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"persistency","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"yield","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"利用草高を一定としたオーチャードグラス放牧専用草地の収量, 栄養価, 永続性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"利用草高を一定としたオーチャードグラス放牧専用草地の収量, 栄養価, 永続性"},{"subitem_title":"Yield, Nutritive Value of Herbage, and Persistency of Orchardgrass Pasture Grazed by Cattle when Plant Height Reaches 25cm","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["148"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"1427","relation_version_is_last":true,"title":["利用草高を一定としたオーチャードグラス放牧専用草地の収量, 栄養価, 永続性"],"weko_creator_id":"12","weko_shared_id":12},"updated":"2023-05-15T15:28:01.170562+00:00"}
