A total of 188 healthy dairy cows (2.4\u2009\u00b1\u20091.3 lactations) with an average milk yield of 42.1\u2009\u00b1\u20096.8\u2009kg milk\/day, at 179\u2009\u00b1\u200938.4\u2009days in milk with 3.8\u2009\u00b1\u20091 AIs were divided into two groups, experimental (E group, <jats:italic>n<\/jats:italic>\u2009=\u200998) and control (C group, <jats:italic>n<\/jats:italic>\u2009=\u200990). The GnRH agonist gonadorelin was given 7\u201314\u2009days after AI to the E group to evaluate the embryo survival in RB cows. The control group did not receive any treatment. Recorded pregnancy rates and cumulative pregnancy rates were superior in the E group (49% and 64.3%) compared with the C group (37.8% and 55.5%). The interaction between therapy and RB had a significant impact on the pregnancy rate and accessory corpus luteum (CL), according to a binary logistic regression study. The UW\u2010DairyRepro$ decision support tool utilized in this experiment demonstrated that by implementing this approach, the net present value can be increased by US dollars (US$)30.2\/RB cow\/year. Thus, the single therapy with GnRH agonist gonadorelin between 7 and 14\u2009days after AI enhanced the potential for a second CL in repeat\u2010breeder pregnant cows, presumably favouring embryo survival.<\/jats:p>","DOI":"10.1111\/rda.14368","type":"journal-article","created":{"date-parts":[[2023,5,3]],"date-time":"2023-05-03T13:28:58Z","timestamp":1683120538000},"page":"929-934","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Economics of treatment with <scp>GnRH<\/scp> agonist 7\u201314\u2009days after artificial insemination in repeat breeder lactating dairy cows"],"prefix":"10.1111","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9601-0788","authenticated-orcid":false,"given":"Silviu\u2010Ionu\u021b","family":"Bor\u015f","sequence":"first","affiliation":[{"name":"Research and Development Station for Cattle Breeding Dancu  Iasi Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4674-6724","authenticated-orcid":false,"given":"Alina","family":"Bor\u015f","sequence":"additional","affiliation":[{"name":"Department of Public Health, Faculty of Veterinary Medicine \"Ion Ionescu de la Brad\" Iasi University of Life Sciences  Iasi Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2425-8957","authenticated-orcid":false,"given":"Ahmed Sabry S.","family":"Abdoon","sequence":"additional","affiliation":[{"name":"Department of Animal Reproduction and Artificial Insemination Veterinary Research Institute, National Research Centre  Cairo Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,5,9]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.2754\/avb201180020171"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2014\u20108954"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/ani11020301"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2018.03.037"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2007.09.001"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.2527\/2005.8361403x"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2019.05.010"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2006.09.038"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2012\u20105704"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2011\u20104376"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2004.09.002"},{"key":"e_1_2_9_13_1","first-page":"411","volume-title":"Applied logistic regression","author":"Hosmer D.
