The individual factor affects blastocyst\/oocyte ratio and determine the existence of outstanding performing animals. The aim of this study was to assess the extent of individual factor effect to IVP efficiency, in a population of Gir oocyte donors. Extreme (high or low IVP efficiency based on blastocyst\/oocyte ratio) animals were selected out of a population of 250 oocyte donors (1,734 observations) to form high (&gt;0.48, <jats:italic>n<\/jats:italic>\u00a0=\u200940), average (0.17\u20130.48, <jats:italic>n<\/jats:italic>\u00a0=\u2009168), and low (&lt;0.17, <jats:italic>n<\/jats:italic>\u00a0=\u200942) efficiency donor groups. Cumulus\u2010oocyte complex indicators (total number, IVF\u2010grade number, and IVF\u2010grade\/total ratio) were lower (<jats:italic>p<\/jats:italic>\u00a0&lt;\u20090.05) in high efficiency donors. The number of blastocysts per OPU was analyzed for highest performing bull, and an increase (<jats:italic>p<\/jats:italic>\u00a0&lt;\u20090.05) in high efficiency donors and a decrease (<jats:italic>p<\/jats:italic>\u00a0&lt;\u20090.05) in low efficiency donors were noticed, compared to average efficiency donors. The number of pregnancies obtained per OPU was affected (<jats:italic>p<\/jats:italic>\u00a0=\u20090.017) by donor's efficiency (low: , average: , high: ), being 4.3\u2010fold higher in high than in low efficiency donors. We conclude that producing embryos from high efficiency blastocyst\/oocyte ratio donors increases blastocyst and pregnancy numbers by OPU, being an important indicator for donor selection in IVP programs.<\/jats:p>","DOI":"10.1111\/asj.13862","type":"journal-article","created":{"date-parts":[[2023,8,8]],"date-time":"2023-08-08T08:53:23Z","timestamp":1691484803000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Outstanding Gir oocyte donors: How does individual factor affect in vitro embryo production efficiency?"],"prefix":"10.1111","volume":"94","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8599-0685","authenticated-orcid":false,"given":"Clara Slade","family":"Oliveira","sequence":"first","affiliation":[{"name":"Embrapa Dairy Cattle  Juiz de Fora Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola Maria da Silva","family":"Rosa","sequence":"additional","affiliation":[{"name":"Embrapa Dairy Cattle  Juiz de Fora Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agostinho Jorge dos Reis","family":"Camargo","sequence":"additional","affiliation":[{"name":"Agricultural Research Company of the Rio de Janeiro State (PESAGRO RIO)  Niteroi Rio de Janeiro Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luiz Fernando","family":"Feres","sequence":"additional","affiliation":[{"name":"Jose do Rosario Vellano University (UNIFENAS)  Alfenas Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naiara Zoccal","family":"Saraiva","sequence":"additional","affiliation":[{"name":"Embrapa Dairy Cattle  Juiz de Fora Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leticia Zoccolaro","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Department of Veterinary Clinics and Surgery, Veterinary School Universidade Federal de Minas Gerais (UFMG)  Belo Horizonte Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luiz Sergio de Almeida","family":"Camargo","sequence":"additional","affiliation":[{"name":"Embrapa Dairy Cattle  Juiz de Fora Minas Gerais Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,8,8]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/ani10122196"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1071\/RD18143"},{"issue":"3","key":"e_1_2_7_4_1","first-page":"487","article-title":"Relationship between follicle population, AMH concentration and fertility in cattle","volume":"12","author":"Baruselli P.
