Nineteen Rhode Island Red laying pullets of 170-days-old were used to determine the effects of graded amounts of dietary selenium on tissues, eggs, urine and faeces (not separated) selenium contents. As basal diet, commercial feed for laying hen containing 0.23 mg selenium per kg. Was provided to laying pullets for 2 weeks. Following basal diet period, pullets were fed on diet containing, respectively, 0.44 and 0.53 mg selenium per kg. For 3 weeks. Blood was obtained to determine selenium levels and GSHpx activities. Concentration of selenium in egg yolk, egg white, urine and faeces was also determind. At the end of each period, six laying pullets were sacrificed to collect the liver and the kidney samples. When a sufficient amount of selenium for physiological requirement was provided to laying pullets, body weight, egg production and others in laying pullets were not improved by the additional supplement of selenium in diets. Blood selenium levels and plasma GSHpx activities were not affected by graded amounts of dietary selenium. It can be seen that selenium over the physiological requirement reduced its utilization. Selenium content in egg white, urine and faeces increased with increasing amount of dietary selenium, but, that in egg yolk was not exactly in propotion to selenium levels of diet. Excretion ratios of selenium in egg yolk, egg white, urine and faeces changed depending on the amount of selenium intake.[著者抄録]産卵鶏のセレン代謝に影響をおよぼす諸要因を検討するための一環として,産卵鶏に適したセレン量の範囲で給与飼料のセレン水準を順次増加させ給与した場合,組織,卵および排泄物中のセレン濃度がいかなる影響を受け,それがセレン代謝とどのような関連性を有するかについて検討した.体重1.9kg,産卵率84%程度の冬季に孵化した170日齢のロードアイランドレッド種の若雌鶏19羽に,基礎飼料としてセレン濃度0.23mg/kgの市販成鶏用飼料を2週間給与し,その後,基礎飼料に亜セレン酸ナトリウムで0.44,0.53mg/kgのセレンを含むように調製した飼料を,それぞれ3週間ずつ給与した.各飼料の給与を開始した後,定期的に採血し,血液セレン濃度および血漿GSHPX活性を測定した.採血を行った日に産卵された卵の卵黄,卵白および排泄物中のセレン濃度についても測定した.また,各期の最終日に6羽をと殺解体し,肝臓および腎臓中セレン濃度の分析に供した.結果の概要は次のとおりであった.生理的に必要とされるセレン量が給与されている若雌鶏に,さらに微量のセレン添加を行っても,その成長や生産性を改善することは期待できなかった.血液セレン濃度や血漿GSHPX活性もほとんど影響を受けなかった.これは吸収されたセレンの利用率が低下することや,体外への排出が増加することによって,平衡状態が保たれたことに起因すると推測された.卵黄,卵白および排泄物中のセレン濃度は飼料のセレン水準によって影響され,卵白や排泄物のセレン濃度は給与セレン水準に比例する傾向にあった.しかし,卵黄では必ずしも比例するとは眠らなかった.摂取セレン量が増加するにつれ,卵黄中に利用されるセレンの割合は低下した.卵白や排泄物においても摂取セレン量が多くなると,それに対する卵白や排泄物中のセレン量の割合は低下した.しかし,さらに摂取セレン量が多くなった場合,その割合は再び増加した.従って,摂取セレン量が毒性レベルに近づく程,恒常性を保つため卵白や排泄物へのセレンの排出は増加すると推測された.","subitem_description_type":"Abstract"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学農学部"}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04538889","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Oishi, Takeshi"},{"subitem_text_language":"en","subitem_text_value":"Inuzuka, Sumio"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部農学科畜産学研究室"},{"subitem_text_value":"近畿大学農学部農学科畜産学研究室"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Laboratory of Animal Science, Department of Agriculture, Faculty of Agriculture, Kinki University"},{"subitem_text_value":"Laboratory of Animal Science, Department of Agriculture, Faculty of Agriculture, Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大石,  武士"},{"creatorName":"オオイシ, タケシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"犬塚,  澄雄"},{"creatorName":"イヌヅカ, スミオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-18"}],"displaytype":"detail","filename":"AN00064044-19840315-0029.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00064044-19840315-0029.pdf","url":"https://kindai.repo.nii.ac.jp/record/5044/files/AN00064044-19840315-0029.pdf"},"version_id":"fed1abb0-4534-455c-ae27-0025903567e1"}]},"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_thumbnail":{"attribute_name":"サムネイル","attribute_value_mlt":[{"subitem_thumbnail":[{"thumbnail_label":"AN00064044-19840315-0029.jpeg","thumbnail_url":"/api/files/03a7b8d0-a33e-44c1-ad44-8b05d39d3fa5/AN00064044-19840315-0029.jpeg?versionId=55fbc942-4079-44af-b726-4f88115bf900"}]}]},"item_title":"飼料へのセレン添加が若雌鶏の組織，卵および排泄物セレン濃度におよぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"飼料へのセレン添加が若雌鶏の組織，卵および排泄物セレン濃度におよぼす影響"},{"subitem_title":"Effects of Supplement of Selenium in Diet on Tissues, Eggs, Urine and Faeces Selenium Concentration in Pullets","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["1443","3064"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-28"},"publish_date":"2008-01-28","publish_status":"0","recid":"5044","relation_version_is_last":true,"title":["飼料へのセレン添加が若雌鶏の組織，卵および排泄物セレン濃度におよぼす影響"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:32:05.853628+00:00"}
