Efeito da pré-estimulação ovariana sobre características de oócitos após punção folicular em bovinos

Abstract: Avaliaram-se os efeitos da pré-estimulação ovariana com FSH e da imunização ativa contra inibina suína sobre o número e classificação morfológica de oócitos recuperados por punção folicular. Catorze vacas da raça Gir, pluríparas e não-lactantes, foram distribuídas em: TI - submetidas a pré-estimulação com 250 UI de FSH (n=4), TII - submetidas a imunização ativa contra inibina suína (n=4) e TIII - não tratadas (n=6; controle). Todos os animais tiveram seus folículos com diâmetro superior a três milímetros aspir… Show more

“…This effect was not observed in the Zebu females. These data agree with those of Viana et al (2003), who showed that FSH increased oocyte quality in protocols for OPU. Gibbons et al (1997) found that FSH promotes embryo development in vitro by synchronizing the follicular population, by inducing in vivo maturation of oocytes, and, therefore, by leading to an increased developmental competence of the oocyte before recovery.…”

“…According to Viana & Bols (2005), the establishment of follicular dominance is the main factor that affects the quality of the oocytes in the pool of developing follicles. Viana et al (2003) found that dry cows undergoing OPU at the beginning of a follicular wave produced more and better quality oocytes.…”
