Artificially injecting the cow with the semen obtained from a good and healthy bull is called artificial insemination.
Advantages:
1. The semen of the desired bull can be easily transported to distant places.
2. It makes selective breeding easier.
ADVERTISEMENTS:
3. The semen from a single bull is generally sufficient for impregnating about 300 cows.
4. The bull need not be taken to the place of insemination.
