Question

What is artificial insemination? Mentions two ways in which it is useful in the breeding of diary animals.

Answer 1

Artificial insemination is done to get a better variety of animals. In this method semen from the desired type of animal (e.g bull) is collected and preserved by chemical methods or freezing. This preserved semen is then injected into the genital tract of the chosen cow during its maximum fertility period. The normal reproductive process then occurs and the progeny thus obtained is a hybrid of desired characters.
Usefulness in breeding animals:
(i) It is economical as semen from a desired animal example, a bull can be transported to faraway places while transporting the animal is not easy.
(ii) High-quality semen is available all the time but a high-quality bull may not be available all the time and at all places.
