Domesticated animals of any breed or population of animal which are intentionally kept in an agricultural setting for the benefit of human beings are referred to as ‘lifestock’. And the agricultural practice of breeding and raising livestock is called animal husbandry. It deals with the care and breeding of animals like buffaloes, cows, pigs, horses, cattle, sheep, camels, goats, etc., by humans for various products like milk, meat, wool, etc. Poultry farming and fisheries are also considered as the part of animal husbandry. According to a survey, about 70% of world’s livestock population is in India and China. Despite this huge production, their contribution to the world farm produce is only 25%, i.e the productivity per unit is very low. Therefore, to improve quality and increase the productivity, there is a need to apply new technologies, in addition to the conventional practices of animal breeding and tare.
