Breeding of Animals

Introduction to Animal Breeding

Animal breeding involves developing different breeds through selective mating. Only the finest pedigree bulls, known for their strength or high milk production from their mothers, are chosen for reproduction. Bulls not selected are typically neutered to be used as oxen.

Types of Breeding

There are two primary types of breeding:

  • Inbreeding: This occurs when animals of the same breed mate. It increases the likelihood of offspring inheriting similar genetic traits, helping to establish a pure breed line. Although inbreeding can bring out harmful genetic traits, which are then removed through selective breeding, it also helps to gather good genes and remove undesirable ones. However, too much inbreeding can reduce fertility and overall productivity, a phenomenon known as inbreeding depression.
  • Outbreeding: This type refers to the mating of unrelated animals, which could be within the same breed but with no common ancestors, or between different breeds, often called crossbreeding. This method can also include inter-species breeding to produce hybrids.

Breeding Methods

Animal breeding can be achieved through natural ways or artificial techniques:

  • Natural Breeding:
    • Random Breeding: Involves letting a few high-quality bulls mingle with cows during grazing, leading to spontaneous mating.
    • Controlled Breeding: This method uses planned mating between local cows and superior foreign bulls like Holstein and Jersey, among others, to enhance breed qualities.
  • Artificial Insemination: This is a more controlled breeding process where semen from a selected male is collected, preserved, and artificially introduced into a female's reproductive tract. This technique is cost-effective as it allows one bull's semen to impregnate thousands of cows. It's also considered more hygienic and reliable than natural mating methods.

Advantages of Artificial Insemination

Artificial insemination is beneficial as it allows for:

  • Economical breeding, using semen from one bull for thousands of cows.
  • Transport of semen to distant locations.
  • Availability of high-quality semen at all times and places.

Frequently Asked Questions on Breeding of Animals

Selective breeding involves choosing animals with desirable traits for reproduction to enhance those traits in future generations.

Inbreeding occurs between closely related animals of the same breed, enhancing purity but potentially leading to health issues. Outbreeding involves mating unrelated animals, which can be from the same breed or different breeds, to increase genetic diversity and vigor.

Artificial insemination is more economical, allows for widespread distribution of high-quality genetic material, and is more hygienic and reliable than natural mating.

Inbreeding can lead to inbreeding depression, where closely related mating results in offspring with lower fertility and vitality due to the concentration of harmful recessive genes.

While commonly used in livestock like cows and horses, artificial insemination is also applicable in other animals but may vary in technique and effectiveness depending on the species.
