Resumo: The objective of this study was to evaluate the influence of the time of embryo transfer, the stage of development and the quality of the transferred embryos, the processing of embryos, from the ipsilateral ovary to the corpus luteum and the size of the corpus luteum, on the pregnancy rate of recipients for in vitro produced bovine embryos from beef and dairy cattle breeds. For this purpose, retrospective data from 419 transfers of in vitro produced bovine embryos were used, 245 from beef cattle breeds and 174 from dairy cattle breeds, between February and November 2021. The pregnancy rate was calculated considering the effects of the time of embryo transfer to recipients, the stage of embryonic development, the quality and processing of the embryo, the ovary ipsilateral to the corpus luteum and the size of the corpus luteum. Mean percentages were compared by using chi-square, using the SAS statistical package version 9.2, considering 5% significance (p<0.05). The 419 transfers of in vitro produced embryos resulted in 29.04% of pregnancy. There was no influence of the timing of embryo transfer to recipients, the stage of embryo development, the ipsilateral ovary to the corpus luteum and the size of the corpus luteum on the pregnancy rate of recipients after transfer of in vitro produced embryos from beef and dairy cattle breeds (p>0.05). However, the quality and processing of in vitro produced embryos exerted effects on the pregnancy rate after embryo transfer from beef and dairy cattle breeds (p<0.05).

However, the quality and processing of in vitro produced embryos exerted effects on the pregnancy rate after embryo transfer from beef and dairy cattle breeds (p<0.05).El objetivo de este estudio fue evaluar la influencia del tiempo de transferencia embrionaria, el estadio de desarrollo y la calidad de los embriones transferidos, el procesamiento de los embriones, desde el ovario ipsilateral hasta el cuerpo lúteo y el tamaño del cuerpo lúteo, sobre la tasa de preñez de las receptoras de embriones bovinos producidos in vitro de razas de ganado vacuno de carne y lechero. Para ello, se utilizaron datos retrospectivos de 419 transferencias de embriones bovinos producidos in vitro, 245 de razas de ganado vacuno de carne y 174 de razas de ganado vacuno lechero, entre febrero y noviembre de 2021. La tasa de preñez se calculó considerando los efectos del momento de la transferencia embrionaria a las receptoras, el estadio de desarrollo embrionario, la calidad y el procesamiento del embrión, el ovario ipsilateral al cuerpo lúteo y el tamaño del cuerpo lúteo. Los porcentajes medios se compararon mediante el chi-cuadrado, utilizando el paquete estadístico SAS versión 9.2, considerando una significancia del 5% (p<0,05). Las 419 transferencias de embriones producidos in vitro resultaron en una tasa de preñez del 29,04%. No hubo influencia del momento de la transferencia de embriones a las receptoras, la etapa de desarrollo del embrión, el ovario ipsolateral al cuerpo lúteo y el tamaño del cuerpo lúteo en la tasa de preñez de las receptoras después de la transferencia de embriones producidos in vitro de razas de ganado vacuno de carne y lechero (p>0.05). Sin embargo, la calidad y el procesamiento de los embriones producidos in vitro ejercieron efectos sobre la tasa de preñez después de la transferencia de embriones de razas de ganado vacuno de carne y lechero (p<0.05).Objetivou-se com esse estudo avaliar a influência do horário da transferência de embriões, do estádio de desenvolvimento e da qualidade dos embriões transferidos, do processamento dos embriões, do ovário ipsilateral ao corpo lúteo (CL) e do tamanho do CL, sobre a taxa de gestação de receptoras embriões bovinos produzidos in vitro (PIV) oriundos de raças de corte e leite. Para tanto, utilizou-se dados retrospectivos de 419 transferências de embriões bovinos PIV, sendo 245 oriundas de embriões de raças de corte e 174 de raças de leite, entre os meses de fevereiro a novembro de 2021. A taxa de gestação foi calculada considerando-se os efeitos do horário de realização da transferência dos embriões a receptoras, da fase de desenvolvimento embrionário, da qualidade e processamento do embrião, ovário ipsilateral ao CL e do tamanho do CL. As porcentagens médias foram comparadas pelo Qui-quadrado, mediante pacote estatístico SAS versão 9.2, considerando 5% de significância (p<0,05). As 419 transferências de embriões produzidos in vitro resultaram em 29,04% de gestação. Não se observou influência do horário da transferência de embriões às receptoras, do estádio de desenvolvimento dos embriões, do ovário ipsilateral ao CL e do tamanho do CL sobre taxa de gestação de receptoras após transferência de embriões PIV oriundos de raças de corte e leite (p>0,05). Contudo, a qualidade e o processamento dos embriões produzidos in vitro exerceram efeitos sobre a taxa de gestação, após transferência de embriões de raças de corte e leite (p<0,05).Research, Society and Development2022-08-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3100210.33448/rsd-v11i11.31002Research, Society and Development; Vol. 11 No. 11; e166111131002Research, Society and Development; Vol. 11 Núm. 11; e166111131002Research, Society and Development; v. 11 n. 11; e1661111310022525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/31002/28312Copyright (c) 2022 Camila Keterine Gorzelanski Trenkel; Adalgiza Pinto Neto; Leandro Francisco Cichoski; Matheus Ramos Rosin; Jonatas Cattelamhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessTrenkel, Camila Keterine Gorzelanski Pinto Neto, AdalgizaCichoski, Leandro Francisco Rosin, Matheus Ramos Cattelam, Jonatas2022-09-05T13:24:46Zoai:ojs.pkp.sfu.ca:article/31002Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:47:31.870269Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
