Última Dominant follicle removal by ultrasound guided transvaginal aspiration and superovulatory response in Nellore cows Arq. Bras. Med. Vet. Zootec. Gradela,A.; Esper,C.R.; Matos,S.P.M.; Lanza,J.A.; Deragon,L.A.G.; Malheiros,R.M.. The present study analyzed the physiological significance of the dominant follicle (DF) and its removal on the superovulatory response of 42 Nellore cows and tested the hypothesis that the number of subordinate small follicles (3-8mm) could be used as a single criterion for the evaluation of the presence or absence of a DF in the ovaries. Ultrasonographic examinations were performed two days before the beginning of superovulatory treatment (D0) and the cows divided into three groups: group without DF (NDF), group with a DF (DF) and group with an aspirated DF (ADF). The superovulatory response of the donors did not differ between groups, but the rate of embryonic viability was higher in NDF (69.40%) and ADF (68.99%) groups compared to DF (48.54%). The...

The aim of this study was to evaluate the influence of the dominant follicle during it’s growing, static and regression phases on the superovulatory response in 18 estral cycles of nelore heifers. The follicular development was monitored by ultrasound from Day 6 to Day 10 (Day 0=estrus) of the oestrus cycle, when the diameter of the largest follicle was measured and the number of subordinate follicles counted. The animals where superovulated with 400 or 500IU of FSH/LH twice daily for 4 days begining on day 10 of the oestrus cycle I was injected PGF2alpha concomitantly with the fifth dose of FSH/LH. Artificial insemination was done 12 and 24 hours after the begining of the estrus. Embryos were recovered on day 6.5 after the first insemination. If a...
