Arrange the following events in Multiple Ovulation Embryo Transfer Technology (MOET) chronologically.

(A) Non surgical recovery of fertilized eggs at 8-32 cells stage and transfer to surrogate mother.
(B) Administration of FSH hormone to cow.
(C) Mating with elite bull or artificially inseminated.
(D) Initiation of superovulation

Choose the correct answer from the options given below:

(B), (D), (C), (A)

The correct answer is Option (1) → (B), (D), (C), (A)

(B) Administration of FSH hormone to cow.

(D) Initiation of superovulation

(C) Mating with elite bull or artificially inseminated.

(A) Non surgical recovery of fertilized eggs at 8-32 cells stage and transfer to surrogate mother.

The success rate of crossing mature male and female animals is fairly low even though artificial insemination is carried out. To improve the chances of successful production of hybrids, other means are also used. Multiple Ovulation Embryo Transfer Technology (MOET) is one such programme for herd improvement. In this method, a cow is administered hormones, with FSH-like activity, to induce follicular maturation and super ovulation – instead of one egg, which they normally yield per cycle, they produce 6-8 eggs.

The animal is either mated with an elite bull or artificially inseminated. The fertilised eggs at 8–32 cells stages, are recovered non-surgically and transferred to surrogate mothers. The genetic mother is available for another round of super ovulation.

This technology has been demonstrated for cattle, sheep, rabbits, buffaloes, mares, etc. High milk-yielding breeds of females and high quality (lean meat with less lipid) meat-yielding bulls have been bred successfully to increase herd size in a short time.
