1. Introduction

Ever since the beginning of civilization, humans have depended on animals for many requirements, such as that of food (milk, meat and egg), clothing (hide or wool), labour (pulling, carrying load) and security etc. The development of desirable qualities in all such animal species, through creating better breeds, has been an important human achievement. For this, humans have consistently tried to improve the breeds of domesticated animals to make them more useful for them.

The branch of science, which deals with the study of various breeds of domesticated animals and their management for obtaining better products and services from them is known as Animal Husbandry. The term husbandry derives from the word “husband”, which means ‘one who takes care’. When it incorporates the study of proper utilization of economically important domestic animals, it is called Livestock Management.
