One hundred and twenty-nine mares of different breeds were included in the study. Eighty-one out of the 107 mares inseminated with fresh, chilled semen got pregnant. Seven pregnant mares aborted and 74 foals were born. Out of the 22 mares inseminated with frozen semen, 17 mares got pregnant. Two mares out of the 17 pregnant mares aborted and finally 15 healthy foals were born. No difference was found between the two groups in the ratio of the foals born (<jats:italic>P<\/jats:italic> &gt; 0.05). The comparison of medians for the number of insemination cycles did not show significant differences. However, a significant difference (Kruskal\u2013Wallis test, <jats:italic>P<\/jats:italic> = 0.014) was found in the number of the inseminations per conception in favour of frozen semen (2.5 vs. 1.8 with fresh chilled and frozen semen, respectively). The Cox regression revealed that the type of semen has a significant impact (<jats:italic>P<\/jats:italic> &lt; 0.001) on the service period (duration of the insemination period): the use of frozen semen prolonged the insemination period. This could be due to management issues, since re-insemination with frozen semen took place after only one\/a few missed oestrous cycles not used for AI.<\/jats:p>","DOI":"10.1556\/004.2020.00007","type":"journal-article","created":{"date-parts":[[2020,5,8]],"date-time":"2020-05-08T08:57:33Z","timestamp":1588928253000},"page":"85-90","update-policy":"https:\/\/doi.org\/10.1556\/policypage.crossmark.crossref.1","source":"Crossref","is-referenced-by-count":3,"title":["Practical experience with artificial insemination (AI) using fresh chilled and frozen semen in mares"],"prefix":"10.1556","volume":"68","author":[{"given":"Andr\u00e1s","family":"G\u00e1sp\u00e1rdy","sequence":"first","affiliation":[{"name":"1Department of Animal Breeding, Nutrition and Laboratory Animal Science, University of Veterinary Medicine, Istv\u00e1n u. 2, H-1078 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eszter","family":"Renk\u00f3","sequence":"additional","affiliation":[{"name":"2Department and Clinic of Reproduction, University of Veterinary Medicine, Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bence","family":"Somosk\u0151i","sequence":"additional","affiliation":[{"name":"2Department and Clinic of Reproduction, University of Veterinary Medicine, Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e1s","family":"B\u00e1ba","sequence":"additional","affiliation":[{"name":"3Polequi Bt., Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8251-4712","authenticated-orcid":true,"given":"S\u00e1ndor","family":"Cseh","sequence":"additional","affiliation":[{"name":"2Department and Clinic of Reproduction, University of Veterinary Medicine, Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"425","reference":[{"key":"ref251","doi-asserted-by":"crossref","first-page":"1102","DOI":"10.1016\/j.theriogenology.2014.07.028","article-title":"Pregnancy rates after artificial insemination with cooled stallion spermatozoa either with or without single layer centrifugation","volume":"82","author":"Morrell","year":"2014","journal-title":"Theriogenology"},{"key":"ref171","first-page":"1232","author":"Carleton","year":"2011","journal-title":"Blackwell's Five-Minute Veterinary Consult Clinical Companion: Equine Theriogenology"},{"key":"ref201","doi-asserted-by":"crossref","first-page":"114","DOI":"10.1016\/j.anireprosci.2017.11.015","article-title":"Associations between management practices and major reproductive parameters of Holstein-Friesian replacement heifers","volume":"188","author":"Fodor","year":"2018","journal-title":"Anim.
