Embryo production and recovery in goats by non-surgical transcervical technique

Transcervical embryo collection in Boer goats.

Two experiments were conducted, aimed at improving the practicability of the method for transcervical embryo collection in Boer goats described by Pereira et al. [Pereira, R.J.T.A., Sohnrey, B., Holtz, W., 1998. J. Anim. Sci. 76, 360-363]. Invention of a hammock-like restraining device, use of a wider-bore flushing catheter and a modified flushing mode contributed toward this end. The importanc...

Repeated surgical embryo recovery and embryo production in rabbits.

The purpose of this study was to assess the embryo production after repeated surgical recovery of embryos in Gigante de España does. A total of 195 ovulatory treatments and embryo recoveries were performed from 1995 to 1999. Ovulation was induced by an intramuscular injection of 20 microg GnRH immediately after mating. Each doe was induced to ovulate up to four consecutive times at intervals of...

Non-surgical embryo recovery in the water buffalo.

Transcervical embryo transfer in performance mares.

Pregnancy was established by transcervical transfer of embryos from performance mares into recipient mares. Estrus was synchronized between donor (n = 17) and recipient (n = 43) mares. After a greater than or equal to 25-mm follicle was detected, donor mares were bred artificially daily until ovulation. Day of ovulation was recorded. Uterine flushes (n = 111) were performed on donor mares 7 day...

Embryo recovery and transfer for the production of transgenic goats from Korean native strain, Capra hircus aegagrus.

During the breeding season in Korea (September 1997 to April 1998), a goat embryo recovery and transfer program using a Korean native strain (Capra hircus aegagrus) was performed for the production of transgenic goats. Donors were synchronized with norgestomet implants and superovulated by a combined treatment with FSH and hCG. The treatment regime induced a consistent and efficient superovulat...
