Name the methods employed in animal breeding. Which methods is best and Why?

Ans. There are two main methods employed in animal breeding - Natural breeding and artificial breeding.

(a) Natural breeding further may be random or controlled :--

(i) Random breeding:--  In this high quality bulls are kept alongwith some cows and this brings about random breeding.

(ii) Controlled breeding :--  In this 

case, mating of native cows with 

superior foreign (exotic) bulls takes 

place.  It includes European breeds e.g., 

Holstein, Brown Swiss, Jersey etc.

(b) Artificial breeding or insemination:- 

In this case, the semen of superior

 males is collected and injected into the vagina or reproductive tract of selected females  by breeder.

The semen can be used immediately 

or can be presumed for later use. In 

case of natural breeding, a large number of sperms are ejaculated or we can say 

that there is a huge wastage of sperms, whereas in artificial insemination a fewer

 number of sperms are required to 

achieve the conception. So, we can 

say the artificial insemination is the 

best  and economical breeding method.
