Livestock contribute to the farming operations of more than 800 million poor smallholders. Rural households can improve their livelihoods by raising a wide variety of animals: cows, buffaloes, sheep, goats, pigs, poultry, camels, llamas, alpacas, horses, donkeys, rabbits and even bees.
It is estimated that the demand for livestock products will more than double over the next 20 years, due to urbanization, economic growth and a change in consumption patterns in developing countries. Livestock is one of the fastest growing agricultural subsectors in developing countries, accounting for about 30 per cent of agricultural GDP.
