(N/A) Modern breeding techniques significantly enhance food production. $A$ key example in animal husbandry is the Multiple Ovulation Embryo Transfer Technology $(MOET)$.
In this method,a cow is administered hormones with $FSH$-like activity to induce follicular maturation and superovulation. Instead of the single egg normally produced per cycle,the cow produces $6-8$ eggs.
The animal is then mated with an elite bull or artificially inseminated. The fertilized eggs at the $8-32$ cell stage are recovered non-surgically and transferred to surrogate mothers. This allows the genetic mother to be available for another round of superovulation.
This technology has been successfully applied to cattle,sheep,rabbits,buffaloes,and mares. It enables the rapid multiplication of high milk-yielding breeds and high-quality meat-yielding bulls,thereby increasing herd size in a short time and addressing food shortages.
