The study population was comprised of 596 lactating dairy cows synchronized for oestrus: 440 were fixed\u2010time inseminated (AI cows), and 156 were given GnRH treatment at the time of embryo transfer (ET cows) 8\u2009days post\u2010oestrus. Of the 596 cows, 235 (39.4%) became pregnant: 175 (39.8%) AI cows and 60 (39.8%) ET cows. Twin pregnancy was recorded in 16% of the AI pregnant cows (28\/175), whereas no ET cows had twins (0\/60). Significant interaction (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.01) was observed between breeding technique (FTAI vs FTET) and repeat (RB) or not repeat breeding (NRB) for the likelihood of pregnancy. This meant that using RB AI cows as reference, the odds ratio for pregnancy in RB ET cows was 2.2 (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.04). In conclusion, transfer of a frozen IVP embryo proved useful to prevent the risk of twin pregnancy without affecting fertility.<\/jats:p>","DOI":"10.1111\/rda.14290","type":"journal-article","created":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T08:05:08Z","timestamp":1667808308000},"page":"358-360","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Direct transfer of a single frozen\u2013thawed in vitro\u2010produced embryo to avoid twin pregnancy in dairy cows"],"prefix":"10.1111","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1413-3862","authenticated-orcid":false,"given":"Fernando","family":"L\u00f3pez\u2010Gatius","sequence":"first","affiliation":[{"name":"Agrotecnio Centre  Lleida Spain"},{"name":"Transfer in Bovine Reproduction SLu  Barbastro Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roger J.","family":"Palac\u00edn\u2010Chauri","sequence":"additional","affiliation":[{"name":"Animal Science University of Lleida  Lleida Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6404-1248","authenticated-orcid":false,"given":"Irina","family":"Garcia\u2010Ispierto","sequence":"additional","affiliation":[{"name":"Agrotecnio Centre  Lleida Spain"},{"name":"Animal Science University of Lleida  Lleida Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,11,11]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022\u20100302(99)75487\u20101"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1262\/jrd.2019\u2010025"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0093\u2010691X(99)00208\u20103"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/rda.13971"},{"volume-title":"Applied logistic regression","year":"1989","author":"Hosmer D.
