ABSTRACT
Humankind has utilised animals and animal products for survival since the dawn of civilisation, be it for food, clothing, or labour. Many animals have also been tamed for companionship, entertainment, research, security, etc. This shows how the animal kingdom has been a beneficial investment for human beings. We can recount from historical lessons that humans depended on animal sources for their nutritional needs, and the agricultural practice of growing one's food was a skill developed much later. While agriculture is now a widespread practice for growing and obtaining food and nutrition, animal food sources remain relevant for a great proportion of the world population, accentuating the need for livestock rearing in the modern world. Livestock rearing is a popular choice of income generation in rural India, with livestock providing subsistence to the owner and acting as a safety net that can cushion the impact of crop failure due to socio-environmental conditions.
