Which of the following is not a step in Multiple Ovulation Embryo Transfer Technology (MOET)?
The correct option is B Cow is administered hormones, with LH-like activity to induce superovulation
Multiple Ovulation Embryo Transfer Technology (MOET) is a part of controlled breeding experiments aimed for herd improvement.
This technology has been demonstrated for cattle, sheep, rabbits etc. High milk-yielding breeds of females and high quality (lean meat with less lipid) meat-yielding bulls are produced successfully by this technique.
Steps in MOET:
- The cow is administered hormones having FSH-like activity, to stimulate follicular maturation and superovulation. Production of 6-8 eggs per oestrus cycle is called superovulation. Usually, the cow produces one egg per cycle.
- Then the female is either mated with a superior bull or artificially inseminated (semen of superior male is injected into the reproductive tract of the cow).
- The fertilised eggs at 8–32 cell stage are recovered non-surgically.
- The embryos collected are then transferred to surrogate mothers in which the further development of embryo takes place.
- The genetic mother is made available for another round of superovulation.
FSH (follicle stimulating hormone) is produced by the anterior pituitary and it stimulates the growth and development of the ovarian follicles. Hence, in MOET, hormones with FSH-like activity are administered to produce more eggs.
LH (luteinizing hormone) is also produced from the anterior pituitary and LH surge causes the mature ovarian follicle to rupture and release the egg.
