In MOET (Multiple Ovulation Embryo Technology), the fertilized eggs from o cow collected in this stages.

Explanation

The following are the steps involved in Multiple Ovulatin and Embryo Transfer (MOET).
* A cow is administrated hormones, with FSH like activity.
* This induces follicular maturation and super ovulation
* In Super ovulation instead of one egg, which they produce per cycle, they produce 6-8 eggs.
* The cow is either mated wiht elite bull or artificially inseminated.
* The embryos are at 8-32 called stages are recovered non-surgically and transferred to surrogate mother, when the embryo develops into complete animals.
Now the genetic mother is ready for another round of super ovulation. This technology is in use for cattle, sheep, rabbits, buffaloes etc, to produce high yielding ones.
