Question

MOET ( Multiple Ovulation Embryo Transfer) is a method of which of the following?
A. Fish cultivation
B. Hybridisation of cattle
C. Birth control
D. Cloning of sheep

Answer 1

MOET is a kind of controlled breeding experiment. This is done to get the desirable characters and a large number of progeny from a single one. The organism is artificially inseminated in multiple ovulation embryo transfer and the traits which are required in progeny is transferred by artificial insemination.

Complete answer:
Multiple Ovulation Embryo Transfer Technology (MOET): It is one of the programmes for herd improvement in this method, a cow is administered hormones, with FSH-like activity, to induce follicular maturation and superovulation – instead of producing one egg, which they normally produce per cycle, they produce 6-8 eggs. The animal is either mated with an elite bull or artificially inseminated. The fertilised eggs are usually recovered at 2-32 cells stages, without using surgical techniques and transferred to surrogate mothers. The genetic mother is available for another round of superovulation. This technology has been demonstrated for cattle, sheep. rabbits, buffaloes, mares, etc. High milk yielding breeds of females and high quality (lean meat with less lipid) meat-yielding bulls have been bred successfully to increase herd size in a short time.
Now let us match this with given options :-
Fish cultivation :- This process is known as pisciculture. Fish is an important component of food and many medicines. In fish cultivation, catching , processing and selling of fish , shellfish takes place for the different purposes of food.
Hybridisation of cattle :- programmes for herd improvement in this method, a cow is administered hormones, with FSH-like activity, to induce follicular maturation and superovulation. This process is called MOET.
Birth control :- the methods of birth control are known as contraception methods. There are many types of contraception like barrier methods, oral pills. They block the pathway of sperm from entering in the vagina.
Cloning of sheep :- the cloned sheep is known as dolly. Sheep are reared for wool , skin and meat. Goats are reared for meat, milk , hair and skin. The first cloned sheep was dolly so the process is named dolly. Thus cloning of sheep is not called MOET.

Our required answer is B. hybridisation of cattle.

Note: one more method of control breeding experiment is artificial insemination:-
Artificial insemination : The semen is collected from the male that is chosen as a parent and acts as a donor and injected into the reproductive tract of the selected female acts as recipient by the breeder. The semen may be used immediately or can be frozen and used at a later date. It can be transported in a frozen form to a place where the female is housed. In this way desirable mating are carried out. Artificial insemination helps us to overcome several problems of normal mating. Often, the success rate of crossing mature male and female animals is fairly low even though artificial insemination is carried out.
