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...

Ten trypanosome isolates were collected at random from cattle at Ghibe, Ethiopia, in February 1993 and all shown to be savannah-type Trypanosoma congolense. When inoculated into naive Boran (Bos indicus) calves, all 10 isolates were resistant to diminazene aceturate (Berenil), isometamidium chlor...

Approximately 320 East African Zebu cows over 36 months of age were monitored monthly from 1986 to 1992 in nine village herds in an area of high trypanosomiasis risk in southwest Ethiopia where there was resistance to all available trypanocidal drugs. Cows were individually treated with diminazen...

Research has been undertaken since 1986 in the Ghibe valley, southwest Ethiopia, monitoring approximately 840 village East African Zebu cattle monthly to assess the effects of trypanosomiasis on productivity. The average monthly trypanosome prevalence between 1986 and 1989 was about 30 percent. M...
