Solution
The correct option is D A - FSH, B - Superovulation, C - Transfer to surrogate mother
MOET stands for Multiple Ovulation Embryo Transfer Technology. This technology demonstrated for cattle, sheep, rabbits, buffaloes, mares, etc has resulted in high milk-yielding breeds of females and high quality (lean meat with less lipid) meat-yielding bulls.
Steps of MOET:
The cow is administered with hormones having follicle stimulating hormone (FSH) like activity, to stimulate follicular maturation and superovulation (releasing 6-8 eggs instead of one egg per cycle).
The female is either mated with a superior bull or artificially inseminated (semen of superior male is injected into the reproductive tract of the cow).
The fertilised eggs at 8–32 celled stage (early embryo) are recovered non-surgically.
The embryos collected are then transferred to surrogate mothers in which the further development of embryo takes place.
The genetic mother is made available for another round of superovulation.
Estrogen hormone is produced by the developing follicles of the ovary. Under the influence of estrogen hormone, cows become sexually receptive. This period of the oestrous cycle is called estrus or heat. Estrogen also triggers the release of GnRH from the hypothalamus.
Progesterone is secreted from the cells of the ruptured ovarian follicle after ovulation. It is required to support and maintain a potential pregnancy if the egg is fertilised.
Oxytocin hormone is released from the posterior pituitary gland into the blood. This hormone helps in the release of milk from the mammary glands after childbirth.
Therefore, the hormone that induces superovulation is FSH.
