Question
What is artificial insemination? Describe this technique.

Answer

Artificial insemination is the process of injecting the semen obtained from a desired male bull of high milk yielding breed into the genital or reproductive tract of female animal during heat period.
Steps involved in artificial insemination are:
  1. The semen of healthy and tough animal of high milk yielding breed is collected.
  2. It is preserved by freezing or chemical methods.
  3. The preserved semen is then injected into the genital tract of the female animal.
  4. The preserved semen is injected during fertility period.
