First paragraph: Animal power accounts for about 20 percent of agricultural mechanization in developing countries; human power accounts for 70 percent, mechanical power 10 percent. The world number of draft animals has been estimated to about 400 billion head, mainly in Asia. Cattle, buffaloes, horses, donkeys and mules are the main draft animals. Camels, elephants, llamas and yaks also may be used. The factor limiting the use of animals for work is their reduced energy potential, which is determined by characteristics and working ability of the species.
