The constantly evolving lifestyle of the population, especially in the developing nations, has brought about a drastic change in the food consumption all over the world. In addition to becoming health conscious, people are also exploring new food habits by shunning their inhibitions regarding certain food products. Countries like China, India, Brazil, Argentina, and Indonesia, among other emerging nations, are witnessing a strong growth in the livestock product consumption as opposed to the developed nations, which are currently stagnant in this regard. The developing nations are witnessing an unprecedented increase in the urban population, along with a rise in the average disposable income. These developments have helped to increase the consumption of animal source foods.
