Abstract:
Poultry production is one of the fastest-growing agricultural market segments globally. The sector significantly guarantees food security for the continually expanding human population on a global scale. Poultry immunity, health, and production are several factors that challenge the future growth of the poultry industry. The emergence and re-emergence of pathogens have an influence on the industry's profitability and competitiveness, and this is one of the main problems it faces. An abundance of infectious diseases has emerged and re-emerged around the world as a result of multiple factors such as climate change, rapid movement of men and material due to trade and tourism, deforestation due to urbanisation, pressures of unmanageable population explosions, predispositions of polluted environment, and so on. Different measures have been taken up by the government for the management of various bacterial, and viral diseases like Marek’s disease, Avian influenza etc. Thus, the present paper reviews various emerging and re-emerging poultry diseases and their constraint on poultry development in India and around the world.
