C. Breeding:

Breeding is the mating of good quality animals to produce highly productive and suitable animals for enhancement of overall performance in the subsequent generations and to augment production and profitability.

There are two types of mating of animals for production of the progenies. These are: 

1. Natural Propagation/Mating: Mating of animals by natural means.

2. Artificial Insemination: Mating is done through artificial means by collecting semen from males and inseminating the females. The method helps in the use of outstanding males and mating them with a large number of females, thereby producing a large number of highly productive and performing progenies.

Types of Breeding:

Basically, there are two methods of breeding:

  • Inbreeding and
  • Outbreeding.

1. Inbreeding:

Breeding of closely related animals than the average relationship within the breed or population concerned is known as inbreeding. This system involves selection of superior males (sire) and superior females (dam) from the same breed who are then mated in pairs.
