Livestock in 2001 included an estimated 1,650,000 hogs, 6,500 sheep, and 3.7 million chickens. That same year there were 86,000 head of cattle, and production was being encouraged with the aim of achieving self-sufficiency in meat supplies. Local poultry and beef production is sufficient to almost meet domestic demand. Beef imports are subject to quota controls. The farming of crocodiles, whose hides are exported, has also been expanded.
