Write the importance of MOET.
MOET – Multiple Ovulation Embryo Transfer is a method in which a cow is administered hormones with FSH (follicular stimulating hormone) like activity. These hormones induce follicular maturation and superovulation in which the cow produces 6–8 eggs per cycle instead of one egg. The cow is mated with an elite bull or artificially inseminated and the fertilized eggs at 8-32 stage is recovered non-surgically and transferred to a surrogate mother.
