UN says rate of livestock breed extinction is 'alarming'
Among the breeds the International Livestock Research Institute says are most at risk are the Ankole cattle, whose drought resistance and rich milk made them prized animals in East and Central Africa until the arrival of European dairy cows.
Similarly, the Red Maasai sheep of East Africa, which have developed genetic resistance to a common parasite, have almost disappeared since the introduction of Dorper sheep from South Africa 15 years ago, the research institute says.
