West African N'Dama cattle have developed a genetic capacity to survive, reproduce and remain productive under trypanosomosis risk. The cellular and molecular bases of this so-called trypanotolerance are not known, but the trait is manifested by the N'Dama's greater capacity to control parasitaem...

In 1986 a project was set up to determine the constraints to production of Zebu cattle under trypanosomiasis risk in the Ghibe valley. Approximately 1800 East African Zebu cattle (EAZC) were resident within the Ghibe valleey during the experimental period (1986 - 1992) and were maintained under t...

A tsetse control campaign was started in January 1991 using a synthetic pyrethroid cypermethrin `pour-on' applied monthly to cattle exposed to high levels of drug-resistant trypanosomes in the Ghibe valley of southwest Ethiopia. In December 1992, a cost-recovery scheme was introduced, and thereaf...

Trypanosomiasis remains the most important constraint to livestock production on the African continent. Chemotherapy, using curative and prophylactic drugs, is the main method of control of the disease in cattle. The exploitation of the trypanotolerance trait of some breeds of large and small rum...

The prevalence, species and intensity of trypanosome parasitaemia over an eighteen-month period, February 1986 to July 1987, are reported for some 700 N`Dama cattle managed in twenty-five village herds in forest and plateau areas of Idiofa, Zaire. The effect of trypanosomiasis and other diseases ...
