What is Multiple Ovulation Embryo Transfer (MOET) technology? Where is it used?###Explain the technique of multiple ovulation embryo transfer (MOET) in animal breeding.
✓

Answer

  1. Multiple Ovulation Embryo Transfer (MOET) technology is used to increase chances of successful production of hybrids.
  2. In this technique, cow is administered with Follicle Stimulating Hormone (FSH) which induces follicular maturation and then the super ovulation is brought about.
  3. By such technique in each cycle, 6 to 8 eggs mature simultaneously.
  4. The cow is then either mated with a superior bull or she is artificially inseminated.
  5. The blastocysts at 8 to 32 cell stage are recovered non-surgically and transferred to surrogate mothers.
  6. The genetic mother who gave the egg is then again subjected to another round of super ovulation.
  7. This technology is used for cattle, sheep, rabbits, buffaloes, etc.
  8. The MOET is used to produce high milk yielding breeds of female and high quality meat yielding bulls with lean meat containing less lipids. It helps in increasing favourable herd size in a short period.
