Explain how and why controlled breeding experiment is carried out in cattle.
Controlled breeding experiments are carried out using arificial insemination in cattle. The semen is collected from the male that is chosen as a parent and injected into the reproductive tract of the selected female (cow) by the breeder.
(i) The stored semen may be used immediately or can be frozen and used at a later
(ii) It can also be transported in a frozen form to where the female is housed.
In this way desirable matings are carried out.
(iii) Helps in improving the quality and quantity of desired yield.
