This study evaluated the efficiency ofeCG<\/jats:styled-content>administration combined with\/without the GnRH<\/jats:styled-content>agonist buserelin for the induction and synchronization of ovulation in weaned sows submitted toFTAI<\/jats:styled-content>. The sows were allocated into three groups. In the control group, the first artificial insemination was performed at the onset of oestrus and repeated every 24\u00a0hr. In theeCG<\/jats:styled-content>+GnRH<\/jats:styled-content>group, sows received 600\u00a0IU eCG<\/jats:styled-content>at weaning and buserelin (10\u00a0\u03bcg) after 86\u201389\u00a0hr ofeCG<\/jats:styled-content>, and in the GnRH<\/jats:styled-content>group, sows received only buserelin after 86\u201389\u00a0hr of weaning. The hormone\u2010treated sows received a singleFTAI<\/jats:styled-content>after 30\u201333\u00a0hr of buserelin application. All the sows were inseminated with homospermic doses (1.5\u00a0\u00d7\u00a0109<\/jats:sup>\u00a0sperm cells\/50\u00a0ml). The interval between weaning and ovulation was shorter (p<\/jats:italic>\u00a0<\u00a0.05) in theeCG<\/jats:styled-content>+GnRH<\/jats:styled-content>(133.3\u00a0hr) and GnRH<\/jats:styled-content>(135.9\u00a0hr) groups than the control (141.5\u00a0hr) group. In theeCG<\/jats:styled-content>+GnRH<\/jats:styled-content>group, the sows ovulated earlier (p<\/jats:italic>\u00a0<\u00a0.05) than those in the GnRH<\/jats:styled-content>group (44.5 vs. 48.2\u00a0hr after buserelin administration). The reproductive performance of GnRH<\/jats:styled-content>sows was not compromised when only sows exhibiting oestrus at the time of insemination were considered, but lower farrowing rate and smaller litter size were observed ineCG<\/jats:styled-content>+GnRH<\/jats:styled-content>sows. The reproductive performance ofeCG<\/jats:styled-content>+GnRH<\/jats:styled-content>sows was primarily compromised because the insemination was performed outside the optimal time relative to ovulation; therefore, it is advisable to inseminate them before 116\u2013122\u00a0hr after weaning.<\/jats:p>","DOI":"10.1111\/rda.12805","type":"journal-article","created":{"date-parts":[[2016,10,7]],"date-time":"2016-10-07T10:14:52Z","timestamp":1475835292000},"page":"76-82","source":"Crossref","is-referenced-by-count":17,"title":["Fixed\u2010time post\u2010cervical artificial insemination in weaned sows following buserelin use combined with\/withouteCG<\/scp>"],"prefix":"10.1111","volume":"52","author":[{"given":"E","family":"Baroncello","sequence":"first","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Veterin\u00e1ria Universidade Federal do Rio Grande Do Sul\u2010 UFRGS Porto Alegre RS Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ML","family":"Bernardi","sequence":"additional","affiliation":[{"name":"Departamento do Zootecnia Faculdade de Agronomia UFRGS Porto Alegre RS Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"AD","family":"Kummer","sequence":"additional","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Veterin\u00e1ria Universidade Federal do Rio Grande Do Sul\u2010 UFRGS Porto Alegre RS Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I","family":"Wentz","sequence":"additional","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Veterin\u00e1ria Universidade Federal do Rio Grande Do Sul\u2010 UFRGS Porto Alegre RS Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"FP","family":"Bortolozzo","sequence":"additional","affiliation":[{"name":"Setor de Su\u00ednos Faculdade de Veterin\u00e1ria Universidade Federal do Rio Grande Do Sul\u2010 UFRGS Porto Alegre RS Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,9,30]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"crossref","first-page":"182","DOI":"10.54846\/jshap\/536","article-title":"Equine chorionic gonadotrophin and porcine luteinizing hormone to shorten and synchronize the wean\u2010to\u2010breed interval among parity\u2010one and parity\u2010two sows","volume":"16","author":"Bennet\u2010Steward K.","year":"2008","journal-title":"Journal of Swine Health and Production"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2005.04.023"},{"key":"e_1_2_9_4_1","first-page":"187","volume-title":"Control of pig reproduction","author":"Br\u00fcssow K.
