Question

Which method is commonly used for improving cattle breeds and why 9 class

Answer 1

 

Crossbreeding indigenous breeds with exotic breeds. Foreign or exotic breeds have higher milk yield and longer lactation period as compared to indigenous breeds. Therefore, indigenous breeds should be cross-bred with exotic breeds. The local breeds are hardy and resistant to several diseases. There are two methods of cross breeding-natural and artificial insemination. Artificial insemination is preferred as frozen semen can be transported, required in small quantity and 'protects the cows from contagious diseases.
