Morphological descriptions were provided for 23 fetuses and the gestational ages were estimated through fetal characteristics and formula application. The specimens were fixed in 10% formalin for subsequent macroscopic and microscopic examination. Histological characterization was performed using haematoxylin\u2013eosin (H&amp;E), Masson's trichrome (MT) and Verh\u00f6eff's staining techniques. The wild boar fetuses exhibited an estimated gestational age of 55\u2009days (in the larger uterus) and 45\u2009days (in the smaller uterus). They displayed well\u2010developed features consistent with domestic pig fetuses, except for the presence of five pairs of mammae. Additionally, the umbilical cord consisted of two arteries, one vein, an allantoic duct, and a vitelline duct (the latter two identified only microscopically), located in the juxtafetal, intermediate and juxtaplacental portions. The arteries and veins were comprised of endothelium, smooth muscle and collagen fibres, with no elastic fibres observed in the vessel walls. The allantoic duct was lined with simple cuboidal epithelium, while the vitelline duct featured a simple squamous epithelium. In conclusion, the morphological characteristics observed in the examined structures align with the expected patterns for species of the <jats:italic>Suidae<\/jats:italic> family. Furthermore, these findings contribute substantially to the morphological characterization of the wild boar, yielding valuable insights into the fetal morphology and the structure of the umbilical cord.<\/jats:p>","DOI":"10.1111\/ahe.13041","type":"journal-article","created":{"date-parts":[[2024,4,17]],"date-time":"2024-04-17T09:06:41Z","timestamp":1713344801000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Fetal external features and morphology of the umbilical cord of wild boars"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-4110-4795","authenticated-orcid":false,"given":"Juliana Normando","family":"Pinheiro","sequence":"first","affiliation":[{"name":"Programa de P\u00f3s\u2010gradua\u00e7\u00e3o Stricto Sensu em Bioci\u00eancia Animal Universidade de Cuiab\u00e1 (UNIC)  Cuiab\u00e1 MT Brazil"},{"name":"Universidade de Cuiab\u00e1 (UNIC)  Cuiab\u00e1 MT Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9980-4994","authenticated-orcid":false,"given":"Rosa Helena","family":"dos Santos\u00a0Ferraz","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s\u2010gradua\u00e7\u00e3o em Ci\u00eancias Veterin\u00e1rias, Faculdade de Medicina Veterin\u00e1ria (FAVET) Universidade Federal de Mato Grosso (UFMT)  Cuiab\u00e1 MT Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0203-439X","authenticated-orcid":false,"given":"Marlon","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Universidade de Cuiab\u00e1 (UNIC)  Cuiab\u00e1 MT Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2202-0331","authenticated-orcid":false,"given":"Tathiana Ferguson","family":"Motheo","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s\u2010gradua\u00e7\u00e3o Stricto Sensu em Bioci\u00eancia Animal Universidade de Cuiab\u00e1 (UNIC)  Cuiab\u00e1 MT Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,4,17]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"Ara\u00fajo J\u00fanior H.
