Question

The technique employed to make a cow ovulate and produce more ova is called:

• A. Embryo transplantation
• B. Superovulation
• C. Random breeding
• D. Controlled breeding

Answer 1

The correct option is B

Superovulation

The correct option is B:

Explanation of the correct option:

1. Superovulation is the series of processes that cause the female to produce more eggs than normal.
2. It is done through the use of gonadotropins which increases the number of embryos.
3. The large numbers of embryos produced are used for embryo transfer.
4. Ten or more live eggs can be collected in each heat from suitable superovulated cows and heifers.

Explanation of the incorrect options:

Option A:

1. Embryo transfer or transplantation is more commonly used in livestock species.
2. It is done where the superovulated animal is bred via artificial insemination
3. Later the embryos (morula or blastocyst stage) are removed and transferred to another female.

Option C:

1. Randomly selected individuals can be mated in a group with multiple fathers, or both males and females can be randomly split into separate breeding groups is called random breeding.

Option D:

1. Controlled breeding is defined as developing certain predetermined strategies for the beginning and end of a breeding season.
2. A controlled breeding season allows you to have a production cycle schedule.
3. Without the controlled breeding season, each cow's production cycle is different, and therefore multiple production cycle plans are required.

Final answer: The technique employed to make a cow ovulate & produce more ova is called superovulation.
