Livestock raising, like agriculture, is divided into two sectors: a traditional system of grazing on communal lands for subsistence needs, and modern, commercial ranches on freehold title land. Livestock numbers recovered in 1991 from a previous drought-related selloff. In 2001, Swaziland had about 615,000 head of cattle, 422,000 goats, 27,000 sheep, 30,000 hogs, 16,000 equines, and 3.2 million chickens. The country produced 14,000 tons of beef in 2001. However, the meat processing industry has been unstable since 1988.
