Multiple Ovulation Embryo Transfer Technology (MOET) has successfully increased the herd size of cattle. The cow is administered with follicle-stimulating hormone (FSH) to induce follicular maturation and superovulation to produce 6 to 8 eggs. It is then mated or artificially inseminated. The fertilised eggs are recovered non-surgically and transferred to a surrogate mother, where they develop into an improved variety.
