In a study investigating digestive and reproductive performance, an atypical caecal arrangement was found in a hen that was unremarkable in regards to body mass, digestive performance and egg productivity in comparison to other hens fed a similar diet. Examination of the gastrointestinal tract revealed a singular tubular outgrowth from the ileo\u2010caecal junction, rather than the typical paired outgrowths. The single caecal duct bifurcated into two separate blind\u2010ended sacs. Similar caecal deviations have been described in adult and juveniles, but no indications of animal performance were reported in these cases. We conclude that if the presence of an abnormal caecal arrangement reduces digestive abilities they were not obvious, and some compensatory mechanism\/s may exist. Alternatively, the abnormal caecal arrangement of our hen might function adequately, such that no compensation in feed intakes or reduced egg productivity was required or observed.<\/jats:p>","DOI":"10.1111\/j.1740-0929.2012.01063.x","type":"journal-article","created":{"date-parts":[[2012,11,20]],"date-time":"2012-11-20T06:31:46Z","timestamp":1353393106000},"page":"97-100","source":"Crossref","is-referenced-by-count":0,"title":["Caecal abnormality in a layer hen (<i><scp>G<\/scp>allus gallus<\/i> forma domestica) not accompanied by deficits in digestive performance or egg productivity"],"prefix":"10.1111","volume":"84","author":[{"given":"Stephanie K.","family":"COURTNEY JONES","sequence":"first","affiliation":[{"name":"Institute of Conservation Biology and Environmental Management School of Biological Sciences University of Wollongong  Wollongong New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam J.","family":"MUNN","sequence":"additional","affiliation":[{"name":"Institute of Conservation Biology and Environmental Management School of Biological Sciences University of Wollongong  Wollongong New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,11,20]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"93","article-title":"The avian cecum: a review","volume":"107","author":"Clench HD","year":"1995","journal-title":"The Wilson Bulletin"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439\u20100396.2012.01332.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.3382\/ps.0681019"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.2307\/1589720"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.2307\/1589392"},{"key":"e_1_2_6_7_1","first-page":"103","article-title":"A deviation in the morphogenesis of caecum in broiler chicken","volume":"45","author":"Mishra UK","year":"2010","journal-title":"Indian Journal of Poultry Science"},{"key":"e_1_2_6_8_1","first-page":"1162","volume-title":"Diseases of Poultry","author":"Peckham MC","year":"1965"},{"key":"e_1_2_6_9_1","volume-title":"Wildlife Feeding and Nutrition","author":"Robbins CT","year":"1993"},{"key":"e_1_2_6_10_1","first-page":"123","volume-title":"The Analysis of Dietary Fibre in Food","author":"Robertson JB","year":"1981"},{"key":"e_1_2_6_11_1","volume-title":"The Avian Embryo: Structural and Functional Development","author":"Romanoff AL","year":"1960"}],"container-title":["Animal Science Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1740-0929.2012.01063.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1740-0929.2012.01063.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,16]],"date-time":"2023-10-16T11:37:47Z","timestamp":1697456267000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1740-0929.2012.01063.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,11,20]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2013,1]]}},"alternative-id":["10.1111\/j.1740-0929.2012.01063.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1740-0929.2012.01063.x","archive":["Portico"],"relation":{},"ISSN":["1344-3941","1740-0929"],"issn-type":[{"value":"1344-3941","type":"print"},{"value":"1740-0929","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,11,20]]}}}
