Resumo: The increase of the world population generates the need to raise the production of food of vegetal and animal origin. In Brazil, livestock farming has evolved, demonstrating the important role of the country in the production of food. In this way, researchers of this productive chain have been looking for technologies related to production and reproduction, above all, to the use of reproduction biotechnologies, seeking to increase the production of different bovine breeds. Thus, the objective of this research was to investigate the efficacy of ovarian FSH super stimulation in bovine Wagyu oocyte donor females on follicular dynamics and in vitro embryo production. Twelve Wagyu animals, aged 12 to 24 months, randomly distributed in a crossover design were used in two groups: Group 1= animals not stimulated with FSH and Group 2= animals stimulated with FSH. The follicular, oocyte and embryonic variables were evaluated. It was observed that ovarian overstimulation in Wagyu oocyte donor cows with FSH improved the mean and large follicles but reduced the rate of oocyte recovery and, despite the best percentage of viable oocytes, there was no improvement in the amount of embryos produced in vitro.

En Brasil, la ganadería ha evolucionado, lo que demuestra el importante papel del país en la producción de alimentos. Así, los investigadores de esta cadena productiva han estado buscando tecnologías relacionadas con la producción y la reproducción, sobre todo, el uso de biotecnologías de reproducción, buscando incrementar la producción de diferentes razas bovinas. Por lo tanto, el objetivo de esta investigación fue investigar la eficacia de la superestimulación de la FSH en hembras bovinas donantes de ovocitos Wagyu sobre la dinámica folicular y la producción de embriones in vitro. Se utilizaron doce animales Wagyu, de edades comprendidas entre 12 y 24 meses, distribuidos aleatoriamente en un diseño cruzado en dos grupos: Grupo 1 = animales no estimulados con FSH y Grupo 2 = animales estimulados con FSH. Se evaluaron variables foliculares, ovocitarias y embrionarias. Se observó que la superestimulación ovárica con FSH en vacas Wagyu donantes de ovocitos aumentó el número de folículos medianos y grandes, pero redujo la tasa de recuperación de ovocitos y, a pesar del mejor porcentaje de ovocitos viables, no hubo mejoría en el número de embriones producidos in vitro.O aumento da população mundial gera a necessidade de elevar a produção de alimentos de origem vegetal e animal.

Dessa forma, pesquisadores dessa cadeia produtiva têm buscado tecnologias relacionadas à produção e reprodução, sobretudo, ao uso de biotecnologias de reprodução, buscando aumentar a produção de diferentes raças bovinas. Assim, o objetivo desta pesquisa foi investigar a eficácia da superestimulação com FSH em fêmeas bovinas doadoras de ovócitos da raça Wagyu sobre a dinâmica folicular e a produção de embriões in vitro. Doze animais Wagyu, com idades entre 12 e 24 meses, distribuídos aleatoriamente em delineamento crossover foram utilizados em dois grupos: Grupo 1= animais não estimulados com FSH e Grupo 2= animais estimulados com FSH. Foram avaliadas as variáveis foliculares, oocitárias e embrionárias. Observou-se que a superestimulação ovariana com FSH em vacas Wagyu doadoras de oócitos aumentou o número de folículos médios e grandes, mas reduziu a taxa de recuperação de oócitos e, apesar da melhor porcentagem de oócitos viáveis, não houve melhora na quantidade de embriões produzidos in vitro.Research, Society and Development2021-08-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1881110.33448/rsd-v10i10.18811Research, Society and Development; Vol. 10 No. 10; e165101018811Research, Society and Development; Vol. 10 Núm. 10; e165101018811Research, Society and Development; v. 10 n. 10; e1651010188112525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/18811/16704Copyright (c) 2021 Fabio Marcelo de Queiróz; Márcia Aparecida Andreazzi; Fábio Luiz Bim Cavalieri; Isabele Picada Emanuelli; Marcelo Marcondes Seneda; Fábio Morotti; Vinicius Eduardo Gargaro Silva; Danieli Aparecida Bobbo Moreski; Antonio Hugo Bezerra Colombohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessQueiróz, Fabio Marcelo deAndreazzi, Márcia Aparecida Cavalieri, Fábio Luiz Bim Emanuelli, Isabele Picada Seneda, Marcelo Marcondes Morotti, FábioSilva, Vinicius Eduardo Gargaro Moreski, Danieli Aparecida Bobbo Colombo, Antonio Hugo Bezerra 2021-10-02T21:49:16Zoai:ojs.pkp.sfu.ca:article/18811Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:51.341557Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
