Livestock can be raised only in the tsetse-free areas, mainly in the Northern Region and along the coastal plains from Accra to the eastern frontier. Ghana's indigenous West African shorthorn is one of the oldest cattle breeds in Africa. Ghanaian livestock farms which can be termed ranches are few; average livestock population for these outfits is about 400 animals. The elimination of deadly epizootic diseases by prophylactic inoculation of cattle (especially with the help of mobile immunization centers) resulted in a rise of the cattle population from 100,000 head in 1930 to 662,000 in 1968 and 1,360,000 in 2001. There were also about 3,200,000 goats, 2,850,000 sheep, 325,000 hogs, and 21,000,000 poultry. Total meat production in 2001 was 167,000 tons. Many live animals and much meat are imported (mainly from Nigeria) to satisfy local demand. A serious problem for the livestock industry continues to be the provision of adequate feed for animals during the dry season. Almost every household in Ghana rears a few animals for home consumption and as capital saving in case of crop failures.
