In humans, such development outside the amniotic cavity is often associated with the formation of amniotic strands, which can lead to developmental malformations. Although congenital defects in the bovine species are uncommon, they typically result in significant economic losses due to production losses and additional veterinary costs. In this case, pregnancy was diagnosed in a primiparous Jersey\u2010Holstein crossbred cow, 56\u2009days after insemination, during routine pregnancy evaluation. Transrectal palpation revealed less uterine enlargement (i.e., corresponding to a 6\u2010week pregnancy) than was expected for the gestational age. Ultrasound examination (using a Draminski, Poland) confirmed a right\u2010horn pregnancy with an ipsilateral corpus luteum. Foetal length was measured at 41\u2009mm, compared to the expected 50\u2009mm at 56\u2009days of gestation, according to the ultrasound software. The foetus exhibited severe malformations, including the complete absence of limbs and gross deformities caudal to the neck. Although the amnion was fluid\u2010filled, the foetus was located outside of it, within the allantochorion. Abortion was induced, but the aborted material was not recovered. The cow successfully conceived again after one oestrous cycle and calved without complications. While most congenital defects are diagnosed postpartum, this case underscores the importance of performing routine ultrasound pregnancy diagnosis to enable the early detection of developmental abnormalities, facilitating timely intervention and reducing economic losses. To our knowledge, this is the first documented case of an extra\u2010amniotic pregnancy in cattle.<\/jats:p>","DOI":"10.1111\/rda.70137","type":"journal-article","created":{"date-parts":[[2025,10,21]],"date-time":"2025-10-21T09:20:41Z","timestamp":1761038441000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Extra\u2010Amniotic Bovine Foetus With Aplasia of the Posterior Body: A Case Report"],"prefix":"10.1111","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-5823-9702","authenticated-orcid":false,"given":"Lu\u00eds Filipe Moreira Martins","family":"Esteves","sequence":"first","affiliation":[{"name":"Department of Production Animal Medicine University of Helsinki  Saarentaus Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juhani","family":"Taponen","sequence":"additional","affiliation":[{"name":"Department of Production Animal Medicine University of Helsinki  Saarentaus Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,10,21]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_9_2_1","DOI":"10.7863\/jum.2009.28.1.77"},{"doi-asserted-by":"publisher","key":"e_1_2_9_3_1","DOI":"10.1007\/bf02957738"},{"key":"e_1_2_9_4_1","first-page":"269","volume-title":"Placental Changes in Amniotic Band Sequence, Extra\u2010Amniotic and Extramembranous Pregnancy","author":"Castro E.","year":"2018"},{"key":"e_1_2_9_5_1","first-page":"2023","volume-title":"All\u2010Island Animal Disease Surveillance Report","author":"Department of Agriculture, Food and the Marine of Ireland","year":"2024"},{"doi-asserted-by":"publisher","key":"e_1_2_9_6_1","DOI":"10.1016\/j.ajog.2019.09.020"},{"doi-asserted-by":"publisher","key":"e_1_2_9_7_1","DOI":"10.3390\/reports7020024"},{"doi-asserted-by":"publisher","key":"e_1_2_9_8_1","DOI":"10.1111\/j.1471\u20100528.1976.tb00819.x"},{"doi-asserted-by":"publisher","key":"e_1_2_9_9_1","DOI":"10.1111\/ahe.12482"},{"doi-asserted-by":"publisher","key":"e_1_2_9_10_1","DOI":"10.1177\/1098612x251341068"},{"doi-asserted-by":"publisher","key":"e_1_2_9_11_1","DOI":"10.1111\/rda.14501"},{"doi-asserted-by":"publisher","key":"e_1_2_9_12_1","DOI":"10.1111\/rda.70067"},{"doi-asserted-by":"publisher","key":"e_1_2_9_13_1","DOI":"10.1111\/j.1600\u20100684.1987.tb00337.x"}],"container-title":["Reproduction in Domestic Animals"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/rda.70137","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T13:26:20Z","timestamp":1765200380000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/rda.70137"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10]]},"references-count":12,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2025,10]]}},"alternative-id":["10.1111\/rda.70137"],"URL":"https:\/\/doi.org\/10.1111\/rda.70137","archive":["Portico"],"relation":{},"ISSN":["0936-6768","1439-0531"],"issn-type":[{"type":"print","value":"0936-6768"},{"type":"electronic","value":"1439-0531"}],"subject":[],"published":{"date-parts":[[2025,10]]},"assertion":[{"value":"2025-06-11","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-10-12","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-10-21","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70137"}}
