Even for free-range hens, conditions may be very crowded. Buffaloes, deer and others Cattle, sheep and goats, pigs and poultry are not the only farm animals. In India and South East Asia, for instance, water buffalo are widely kept, partly for meat and milk and partly for pulling ploughs and carts. In Africa, Asia and South America, asses and mules are kept for carrying things and to turn water wheels. Deer were once hunted for their meat, called venison, and now they too are sometimes farmed.
Reindeer are large deer with antlers that live in the cold regions of Eurasia and North America.
They were first domesticated 1500 years ago in Lapland and Siberia, where they are used to provide transport, meat, milk and clothing. Pigs Pigs are kept for their meat and their skins, which give fine leather. Their hair is often used for artists' brushes. Pigs were once allowed to roam woodlands, rooting for worms, roots and shoots. Now pigs in Europe and North America are usually raised on factory farms.
