Animal breeding is producing improved breeds of domesticated animals by improving their genotypes through selective mating. There are two methods of animal breeding, natural breeding which includes inbreeding, out-breeding, cross-breeding, out-crossing, etc., and artificial breeding which involves artificial insemination and multiple ovulation embryo transfer technology (MOET). It involves inseminating the native cows with the semen of superior bulls of exotic or indigenous breeds.

Artificial breeding is the best method of breeding because of the following reasons:

• Semen collected from males may be used immediately or can be frozen and used later.
• The semen of desired bulls is collected under hygienic conditions, preserved, and sent to all insemination centres throughout the country.
• Semen collected from one bull can be used to inseminate many cows as fewer sperms are required to achieve conception when semen is deposited artificially. Hence, artificial insemination is very economical.
• It is healthier as the spread of sexually transmitted diseases can be controlled by this technique.
