In total, 1,111 artificial inseminations (AI<\/jats:styled-content>) were analyzed. At AI<\/jats:styled-content>, PF<\/jats:styled-content> locations were examined using rectal palpation, and heifers were divided into two groups on their PF<\/jats:styled-content> locations: (i) the PF<\/jats:styled-content> located in the left ovary (L\u2010PF<\/jats:styled-content>); and (ii)\u00a0the PF<\/jats:styled-content> located in the right ovary (R\u2010PF<\/jats:styled-content>). Pregnancy was diagnosed by rectal palpation 60\u00a0days after AI<\/jats:styled-content>. The conception rate was 50.7% in all heifers. Conception rate was significantly higher in the L\u2010PF<\/jats:styled-content> (60.1%) than in the R\u2010PF<\/jats:styled-content> (46.2%). The conception rate was significantly lower by sexed semen (48.6%) than conventional semen (59.1%). Conception rates divided by the semen type (sexed: n<\/jats:italic>\u00a0=\u00a0896, conventional: n<\/jats:italic>\u00a0=\u00a0215) were significantly higher in the L\u2010PF<\/jats:styled-content> than in the R\u2010PF<\/jats:styled-content> for both semen types (sexed; L\u2010PF<\/jats:styled-content> vs. R\u2010PF<\/jats:styled-content>: 57.3% vs. 44.4%, conventional; L\u2010PF<\/jats:styled-content> vs. R\u2010PF<\/jats:styled-content>: 72.3% vs. 53.3%). In addition, season, age, AI<\/jats:styled-content> number, and the number of re\u2010inseminations at the same estrus did not affect conception rates. In summary, PF<\/jats:styled-content> development in the left ovary was associated with increased conception rates in dairy heifers.<\/jats:p>","DOI":"10.1111\/asj.12949","type":"journal-article","created":{"date-parts":[[2017,11,8]],"date-time":"2017-11-08T09:56:39Z","timestamp":1510134999000},"page":"328-331","source":"Crossref","is-referenced-by-count":6,"title":["Relationship of the conception rate and the side (left or right) of preovulatory follicle location at artificial insemination in dairy heifers"],"prefix":"10.1111","volume":"89","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4945-0649","authenticated-orcid":false,"given":"Ryotaro","family":"Miura","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine Nippon Veterinary and Life Science University Musashino Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taiki","family":"Izumi","sequence":"additional","affiliation":[{"name":"Tokachi NOSAI Obihiro Hokkaido Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,11,8]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0093-691X(02)01296-7"},{"key":"e_1_2_6_3_1","doi-asserted-by":"crossref","first-page":"481","DOI":"10.1016\/j.theriogenology.2013.11.003","article-title":"Complex interrelationships among CL, preovulatory follicle, number of follicular waves, and right or left ovaries in heifers","volume":"81","author":"Ginther OJ","year":"2014","journal-title":"Theriogenology"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2012-5465"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/bmt.2012.244"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(06)72541-3"},{"key":"e_1_2_6_7_1","doi-asserted-by":"crossref","first-page":"318","DOI":"10.3168\/jds.2014-8388","article-title":"Short communication: development of the first follicular wave dominant follicle on the ovary ipsilateral to the corpus luteum is associated with decreased conception rate in dairy cattle","volume":"98","author":"Miura R","year":"2015","journal-title":"Journal of Dairy Science"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(38)95610-3"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.2527\/2002.8041053x"}],"container-title":["Animal Science Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fasj.12949","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/asj.12949","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,26]],"date-time":"2023-09-26T04:05:39Z","timestamp":1695701139000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/asj.12949"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,11,8]]},"references-count":8,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2018,2]]}},"alternative-id":["10.1111\/asj.12949"],"URL":"https:\/\/doi.org\/10.1111\/asj.12949","archive":["Portico"],"relation":{},"ISSN":["1344-3941","1740-0929"],"issn-type":[{"value":"1344-3941","type":"print"},{"value":"1740-0929","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,11,8]]}}}
