Question

High milk yielding varieties of cows are obtained by

(a) super ovulation

(b) artificial insemination

(c) use of surrogate mother

(d) All of the above

Answer 1

Correct Option (a) super ovulation

Explanation:

In super ovulation, a high milk yielding cow is induced to shed 4-6 eggs every 6-8 weeks (instead of 20-21 days). The super ovulated donor is artificially inseminated with semen from a quality bull. the embryos developing from the eggs so fertilised are flushed out. These good quality embryos are now transferred to surrogate mother for delivery.
