Moreover, three different types of seminal doses were used for AI depending on the ejaculate fraction included (F1: doses containing only the rich fraction of the ejaculate; F2: F1 + the transition fraction between rich and poor fractions; F3: F2 and poor fraction). The statistical analysis revealed significant differences in some indices regarding the period of analysis (D0, D1, and D5). Diastolic velocity and mean velocity showed lower values at D5 in comparison with D0 and D1 (p &lt; 0.01). On the other hand, the pulsatility index and the relationship systolic velocity\/diastolic velocity indicated higher values at D5 in comparison with D0 and D1 (p &lt; 0.01). No differences were observed regarding the type of seminal dose used in any of the time points analyzed (p &gt; 0.05). Neither insemination per se nor the type of ejaculate fraction used immediately modified the uterine vascularity, but some indices are affected by the stage of the estrus cycle (estrus vs. early diestrus).<\/jats:p>","DOI":"10.3390\/vetsci9060260","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T05:25:42Z","timestamp":1653974742000},"page":"260","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Analysis of Uterine Blood Flow in Breeding Sows through the Estrus and Early Diestrus, and after Artificial Insemination"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5713-485X","authenticated-orcid":false,"given":"Salvador","family":"Ruiz","sequence":"first","affiliation":[{"name":"Departamento de Fisiolog\u00eda, Facultad de Veterinaria, Campus de Excelencia Mare Nostrum Universidad de Murcia, 30100 Murcia, Spain"},{"name":"Instituto Murciano de Investigaci\u00f3n Biosanitaria Hospital Virgen de la Arrixaca (IMIB-Virgen de la Arrixaca), 30120 Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5301-2174","authenticated-orcid":false,"given":"Juan Carlos","family":"Gard\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, Faculty of Veterinary and Experimental Sciences, Catholic University of Valencia-San Vicente M\u00e1rtir, Guillem de Castro 106, 46003 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9599-1107","authenticated-orcid":false,"given":"Iv\u00e1n","family":"Hern\u00e1ndez-Caravaca","sequence":"additional","affiliation":[{"name":"Instituto Murciano de Investigaci\u00f3n Biosanitaria Hospital Virgen de la Arrixaca (IMIB-Virgen de la Arrixaca), 30120 Murcia, Spain"},{"name":"Departamento de Enfermer\u00eda Comunitaria, Medicina Preventiva y Salud P\u00fablica e Historia de la Ciencia, Facultad Ciencias de la Salud, Campus de Sant Vicent del Raspeig, E-03080 Sant Vicent del Raspeig, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chiara","family":"Luongo","sequence":"additional","affiliation":[{"name":"Departamento de Fisiolog\u00eda, Facultad de Veterinaria, Campus de Excelencia Mare Nostrum Universidad de Murcia, 30100 Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco Alberto","family":"Garc\u00eda-V\u00e1zquez","sequence":"additional","affiliation":[{"name":"Departamento de Fisiolog\u00eda, Facultad de Veterinaria, Campus de Excelencia Mare Nostrum Universidad de Murcia, 30100 Murcia, Spain"},{"name":"Instituto Murciano de Investigaci\u00f3n Biosanitaria Hospital Virgen de la Arrixaca (IMIB-Virgen de la Arrixaca), 30120 Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"225","DOI":"10.1051\/rnd:2003022","article-title":"Determination by echography of uterine changes around puberty in gilts and evaluation of a diagnosis of puberty","volume":"43","author":"Royer","year":"2003","journal-title":"Reprod.
