As the African continent is faced with the challenge of meeting a growing demand for milk and meat, the genetic diversity of livestock breeds is being lost  at an alarming rate. Governments and agribusiness continue to promote  exotic commercial breeds of livestock that are bred to gain more weight  and produce more milk than traditional breeds. The U.N. Food and  Agriculture Organization (FAO) warns that around 1,710 breeds of livestock—21 percent—are at risk of extinction  worldwide as farmers abandon their traditional breeds. For millennia,  pastoralists have bred livestock that are well-adapted to local  conditions. Understanding and preserving these breeds could be useful in  helping communities adapt as their climates and environments change in  the coming decades.

N’Dama is  a hardy breed of cattle indigenous to the Fouta-Djallon highlands in  the West African country of Guinea. N’Dama cows were domesticated around  8,000 years ago in the region and they have evolved to be resistant to  local diseases and parasites. The breed is common throughout West and  Central Africa, especially in areas infested by the tsetse fly—an insect known to transmit disease to both humans and livestock. According to the FAO, there are approximately 7 million head of N’Dama cattle. 
N’Dama cows produce two to three liters of milk per day and their  meat is renowned for its flavor. The breed is the most popular among  West Africa’s small-scale, low-input livestock keepers. This is largely because they are heat tolerant, are docile and do well in harsh environments, and can survive on poor quality feeds.
 But the most important quality of N’Dama is its resistance to trypanosomiasis,  a widespread African cattle disease spread by the tsetse fly. In the  areas of Africa with the greatest potential to increase domestic  livestock production, trypanosomiasis is a major constraint. Because of  its natural resistance to the disease, N’Dama cows do not require  expensive antibiotics to be healthy. For this reason, N’Dama is seen as  the breed of choice to help West and Central Africa meet the increasing  demand for meat and milk products.
 The International Trypanotolerance Centre (ITC)  has launched an N’Dama improvement program in The Gambia. The program  uses 400 breeding cows to try and select larger, higher milk-producing  animals that retain disease-resistant qualities. A company in the  Democratic Republic of Congo called Jules VAN LANCKER, in collaboration with the International Livestock Research Institute (ILRI),  has used its herd of over 40,000 purebred N’Dama to breed desirable  qualities without losing hardiness. According to ILRI, the company has  increased the average weight of its N’Dama cattle by 30 to 50 kilograms  per animal through selective breeding.
 Economically, livestock production  is the fastest growing sector in agriculture worldwide.  Livestock-keeping can be an important way to improve diets and raise  incomes in the developing world. Less well-known livestock breeds  contain valuable resources that could be vital for food security and  help farmers deal with the challenges of climate change, animal disease,  and dwindling water supplies.
