Which of the following is not a step in Multiple Ovulation Embryo Transfer Technology (MOET)?
Correct Answer :
Cow is administered hormone having LH like activity for super ovulation
Solution :
Multiple Ovulation Embryo Transfer Technology (MOET) is a widely used biotechnology program for herd improvement in animals such as cattle, sheep, rabbits, buffaloes, and mares.
Let us break down the standard steps involved in the MOET procedure:
1. Induction of Super Ovulation: A genetic mother (cow) is administered hormones with FSH-like (Follicle Stimulating Hormone) activity to induce follicular maturation and super ovulation. FSH is responsible for stimulating the growth of ovarian follicles. Administering a hormone with LH-like (Luteinizing Hormone) activity for this step is incorrect, as LH triggers ovulation of a matured follicle rather than the development of multiple follicles.
2. Increased Egg Production: Due to super ovulation, the cow yields about 6-8 eggs per cycle instead of the normal single egg.
3. Insemination: The super-ovulated cow is either mated with an elite bull or fertilized by artificial insemination.
4. Embryo Recovery and Transfer: The fertilized eggs are allowed to develop. Once they reach the 8-32 cell stage, they are recovered non-surgically and transferred to surrogate mothers. This leaves the genetic mother free for another round of super ovulation.
Therefore, the step that is not part of the MOET process is the administration of a hormone with LH-like activity, since FSH-like hormone is used instead.
