Fifteen hens (10 of them were 1 year old hens, 5 were 2 years old hens) were kept in the temperature room from 25 to 35°C changing by 2.5°C at each interval during 10-15 days. The results obtained were as follows;    1) The higher the temperature becomes, the lesser food intake was observed. The decreasing rate was 1.6% per Centigrade rise of environmental temperature from 25°C to 35°C. Water consumption increased with the rise of temperature. Each ratio of water consumed per one g of food intake was about 2 times at 32.5°C, and about 3 times at 35°C as much as that at 25°C.    2) Egg production rate was lowest at 35°C, being 73%. Daily egg production was also lowest at 35°C, but food efficiency for egg production, was highest at 35°C, being 61%.    3) Excluding abnormal eggs, net efficiency for egg production was highest at 32.5°C, being 53%, but being 42% at 35°C. Appearing rate of abnormal eggs was attained to 31% at 35°C. Comparing 25°C with 32.5°C, the latter temperature regime had by 15% higher food converting efficiency. The reason for the highest food converting rate for egg production at 32.5°C was discussed.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"広島大学水畜産学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186819068":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15027/41148","subitem_identifier_reg_type":"JaLC"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0440-8756","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00213563","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"開始ページ","attribute_value_mlt":[{"subitem_start_page":"151"}]},"item_1617187056579":{"attribute_name":"bibliographic_information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1971-03-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicPageEnd":"160","bibliographicPageStart":"151","bibliographicVolumeNumber":"9","bibliographic_titles":[{"bibliographic_title":"広島大学水畜産学部紀要"},{"bibliographic_title":"Journal of the Faculty of Fisheries and Animal Husbandry, Hiroshima University"}]}]},"item_1617258105262":{"attribute_name":"item_1617258105262","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"40018463931","subitem_relation_type_select":"NAID"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"JFacFishAnim_9_151.pdf","filesize":[{"value":"985.3 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2038114/files/JFacFishAnim_9_151.pdf"},"version_id":"2204aab1-fe19-400a-a021-524b164fcb98"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"41148"},"item_title":"Effects of Environmental Temperature on Egg Production, Food Intake and Water Consumption in Laying White Leghorns","item_type_id":"40003","owner":"41","path":["1730444255063"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2038114","relation_version_is_last":true,"title":["Effects of Environmental Temperature on Egg Production, Food Intake and Water Consumption in Laying White Leghorns"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-06-09T03:48:00.256866+00:00"}
