Embryo Recovery

The present study was performed to evaluate the recovery of embryos using a combination of laparotomy and laparoscopy techniques.

Induction of Estrus

The induction of estrous synchronization was performed by inserting a CIDR (a progesterone releasing device) in the vagina for 14 days. On day 7 after the first insertion, the CIDR was replaced by a new one. Multiple ovulation was induced by an intramuscular injection of 12 mg FSH, and 300 IU PMSG on day 12 following the first CIDR insertion. Fifty ug of GnRH was injected intramuscularly 24 hours after the removal of the CIDR.

Effects on Embryos

Observation of the ovaries indicated that 27 corpora lutea and 6 follicles were present. The embryos were collected using a combination of laparotomy and laparoscopy on day 5 following oestrus (DS) or day 7 following CIDR removal. Embryo collection resulted in the recovery of 13 embryos and 1 oocyte (51.8%).

Quality of Embryos

All embryos (13) were categorized in the early morulla stage, and they were all of good quality for being transferred. It can be concluded that a combination of laparotomy and laparoscopy is a successful technique for collecting embryos from Angora goats.
