However, that the trade of IVP-cryopreserved pig embryos is expected to start in the next decades. Society and governments are increasingly aware of the repercussions that IVP could have for animal health, welfare, behavior, or food safety, but proven scientific information for this type of animal does not exist, since no colonies of pigs have been created to this end. We created a small one and studied the differences between 16 IVP-derived pigs and 14 pigs derived from artificial insemination (AI), at 3.5 years of age, conceived from the same boar, and housed and fed under the same conditions since they were born. Incidence of lameness, position in the herd hierarchy, weight, adenosine deaminase activity, and hematological and biochemical analytes were compared between the two groups of animals. The results showed that the IVP animals weighed more, occupied higher positions in the herd hierarchy, and had a lower incidence of lameness. Although genetic differences from the maternal line could explain some of these results, it is also possible that the IVP animals developed better adaptative abilities, but more studies with a higher number of animals are necessary to reach consistent conclusions.<\/jats:p>","DOI":"10.3390\/ani12243578","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T07:27:30Z","timestamp":1671434850000},"page":"3578","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Differences in Weight, Hierarchy, and Incidence of Lameness between Two Groups of Adult Pigs Derived from Assisted Reproductive Technologies"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7779-6869","authenticated-orcid":false,"given":"Jon","family":"Romero-Aguirregomezcorta","sequence":"first","affiliation":[{"name":"Physiology of Reproduction Group, Department of Physiology, Faculty of Veterinary Medicine, International Excellence Campus for Higher Education and Research (Campus Mare Nostrum), University of Murcia, 30100 Murcia, Spain"},{"name":"Instituto Murciano de Investigaci\u00f3n Biosanitaria (IMIB), 30120 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisette L.","family":"Ram\u00edrez","sequence":"additional","affiliation":[{"name":"Physiology of Reproduction Group, Department of Physiology, Faculty of Veterinary Medicine, International Excellence Campus for Higher Education and Research (Campus Mare Nostrum), University of Murcia, 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alba","family":"Ort\u00edn","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, Faculty of Veterinary Medicine, International Excellence Campus for Higher Education and Research (Campus Mare Nostrum), University of Murcia, 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5580-1612","authenticated-orcid":false,"given":"Guillermo","family":"Ramis","sequence":"additional","affiliation":[{"name":"Instituto Murciano de Investigaci\u00f3n Biosanitaria (IMIB), 30120 Murcia, Spain"},{"name":"Department of Animal Production, Faculty of Veterinary Medicine, International Excellence Campus for Higher Education and Research (Campus Mare Nostrum), University of Murcia, 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0492-289X","authenticated-orcid":false,"given":"Raquel","family":"Romar","sequence":"additional","affiliation":[{"name":"Physiology of Reproduction Group, Department of Physiology, Faculty of Veterinary Medicine, International Excellence Campus for Higher Education and Research (Campus Mare Nostrum), University of Murcia, 30100 Murcia, Spain"},{"name":"Instituto Murciano de Investigaci\u00f3n Biosanitaria (IMIB), 30120 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3943-1890","authenticated-orcid":false,"given":"Pilar","family":"Coy","sequence":"additional","affiliation":[{"name":"Physiology of Reproduction Group, Department of Physiology, Faculty of Veterinary Medicine, International Excellence Campus for Higher Education and Research (Campus Mare Nostrum), University of Murcia, 30100 Murcia, Spain"},{"name":"Instituto Murciano de Investigaci\u00f3n Biosanitaria (IMIB), 30120 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Maes, D., Lopez Rodriguez, A., Rijsselaere, T., Vyt, P., and van Soom, A.
