1. PROGRAMMING
The donors and recipients must have synchronized heat cycles.
An effective method of increasing the reproduction rate of top Genetic animals
All female animals are capable of producing far more eggs than they ever need over their lifetime. ET uses Follicle Stimulating Hormones (FSH) to cause the ovaries to release more than one egg in a cycle. Multiple eggs can then be fertilised inside the animal and collected surgically, usually 5/6 days after artificial insemination. These embryos can be transferred into surrogate mothers (recipients) who are at the same stage of their cycle but have not been mated. Many of these embryos are accepted by the recipients and a normal pregnancy occurs. Alternatively, embryos can be frozen for sale, export or later transfer.
- 2. DONOR FERTILIZATION
Donor fertilization is done with the Laparoscopic AI. procedure using fresh or frozen semen
- 3. EMBRYO RECOVERY
Embryo recovery is a surgical procedure carried out under general anaesthesia
Embryos are flushed out of the uterine horns
Once embryo recovery is finished, surgical incisions are sutured and antibiotics administered
- 4. EMBRYOLOGY
The embryos are flushed into a Petri dish, and searched under the microscope.
Once found, the embryos are counted, graded and washed. The embryos can now be loaded for transfer or frozen
- 5. EMBRYO TRANSFER
Embryo Transfer is a non-surgical procedure by Laparoscopic AI. Laparoscopic ovary examination of recipients must be performed to ensure that the recipients have good CL (Corpora lutea) of the oestrus cycle available. The embryos are placed in the uterine horn
- 6. GENERAL CONCLUSION
Embryo Transfer can increase the number of offspring from superior genetics. A lamb is 50% of the ewe. An ewe can produce more or less 12 lambs in her lifetime. Embryo flushing is thus the only technique to rapidly multiply the genetics of the ewe
- 7. STATE OF THE ART TECHNOLOGY
Embryos can also be matured in an incubator. Immediately after retrieval of the embryos on day 5, the embryos are placed into the incubator that is warmed to a temperature of 37֯C. A special concentration of gas is added to the tube containing the embryos, to help the development / maturing of the embryos. The embryos are then transferred as usual on day 6. This method makes it possible to travel long distances with the embryos and still transfer fresh embryos
- 8. EXPORT OF SUPERIOR GENETICS
RAMSEM is a registered quarantine export centre that complies with all health protocols
The export of embryos is more viable and more costly than exporting live animals.
The possibility of transferring diseases via an embryo, is a lot less than with live animals,
The embryos are washed repeatedly before being frozen.
