Twenty-six fertile Andalusian jennies were used. In Experiment 1, jennies (n = 112 cycles) were randomly treated with either LUP or DIN after embryo flushing. In Experiment 2, donors (n = 84 cycles) were randomly treated with either hCG or DES to induce ovulation. No differences were found between prostaglandins for all variables studied (prostaglandin\u2013ovulation interval (POI), interovulatory interval (IOI), embryo recovery rate (ERR), positive flushing rate (PFR) and embryo grade (EG)). The ovulation rate was similar for hCG and DES (60.9% vs. 78.7%). However, the interval to ovulation (ITO) was affected (62.61 \u00b1 7.20 vs. 48.79 \u00b1 2.69 h). None of the other variables studied (ERR, PFR and EG) were affected (p &gt; 0.05), except for embryo quality (p = 0.009). In short, both prostaglandins evaluated are adequate to induce luteolysis and estrus. Both ovulation-inducing agents hastened ovulation, but DES seems to be more effective than hCG. Follicular diameter affected the interval from treatment to ovulation, and high uterine edema was related to low embryo quality.<\/jats:p>","DOI":"10.3390\/ani12020143","type":"journal-article","created":{"date-parts":[[2022,1,9]],"date-time":"2022-01-09T20:29:26Z","timestamp":1641760166000},"page":"143","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Hormonal Management for the Induction of Luteolysis and Ovulation in Andalusian Jennies: Effect on Reproductive Performance, Embryo Quality and Recovery Rate"],"prefix":"10.3390","volume":"12","author":[{"given":"Marina","family":"Bottrel","sequence":"first","affiliation":[{"name":"Veterinary Reproduction Group, Department of Animal Medicine and Surgery, Faculty of Veterinary Medicine, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2479-498X","authenticated-orcid":false,"given":"Isabel","family":"Ortiz","sequence":"additional","affiliation":[{"name":"Veterinary Reproduction Group, Department of Animal Medicine and Surgery, Faculty of Veterinary Medicine, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7830-7422","authenticated-orcid":false,"given":"Manuel","family":"Hidalgo","sequence":"additional","affiliation":[{"name":"Veterinary Reproduction Group, Department of Animal Medicine and Surgery, Faculty of Veterinary Medicine, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"D\u00edaz-Jim\u00e9nez","sequence":"additional","affiliation":[{"name":"Veterinary Reproduction Group, Department of Animal Medicine and Surgery, Faculty of Veterinary Medicine, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Blasa","family":"Pereira","sequence":"additional","affiliation":[{"name":"Veterinary Reproduction Group, Department of Animal Medicine and Surgery, Faculty of Veterinary Medicine, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e9sar","family":"Consuegra","sequence":"additional","affiliation":[{"name":"Veterinary Reproduction Group, Department of Animal Medicine and Surgery, Faculty of Veterinary Medicine, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed Samy","family":"Yousef","sequence":"additional","affiliation":[{"name":"Department of Theriogenology, Faculty of Veterinary Medicine, Assiut University, Assiut 71515, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4310-7663","authenticated-orcid":false,"given":"Jes\u00fas","family":"Dorado","sequence":"additional","affiliation":[{"name":"Veterinary Reproduction Group, Department of Animal Medicine and Surgery, Faculty of Veterinary Medicine, University of Cordoba, 14014 Cordoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"563","DOI":"10.1016\/j.theriogenology.2011.08.032","article-title":"Embryo quality and transcervical technique are not the limiting factors in donkey embryo transfer outcome","volume":"77","author":"Panzani","year":"2012","journal-title":"Theriogenology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1016\/j.anireprosci.2008.03.016","article-title":"Differences in ability of jennies and mares to conceive with cooled and frozen semen containing glycerol or not","volume":"112","author":"Vidament","year":"2009","journal-title":"Anim.
