The livestock sector is an important component of the global food system and means to poverty reduction, food security and agricultural development. A large masses depends on agriculture and allied sector. As per FAO, livestock contributes 40 per cent of the global value of agricultural output and supports the livelihoods and food and nutritional security of almost 1.3 billion people. There is wide scope to improve livestock sector practices to make it more sustainable, more equitable, and pose less risk to animal and human health. With increasing incomes, changing diets, and population growth have led to increased demand for food and food products and made the livestock sector one of the fastest growing sub-sector of agriculture. Currently, the livestock sector emits an estimated 7.1 GT of CO2-equivalent per year, almost representing 14.5% of human-induced greenhouse gas (GHG) emissions. Sustainability may be increased by improving the efficiency of livestock supply chains and limiting the growth of GHG emissions in the future. Animal production system can be made more sustainable by maintaining healthy animals as they produce more and make the production process much more efficient and profitable for the farmer. Adoption of innovation within supplements and vaccines that help to cut production of methane within the digestion process. Thus, we can say that a combination of innovation, good animal health and welfare will ensure more efficient farming practices and therefore increasingly sustainable livestock production system that finally contributes in income and employment generation for farming community.
