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...

Nine hundred and thirty-six East African Zebu village calves in an area of high trypanosomiasis risk in south-western Ethiopia were monitored monthly with their dams from birth to 3 years of age. Mean packed red cell volume (PCV) and the frequency of detected parasitaemia were calculated for each...

In order to assess the effect of tsetse control on livestock productivity, 21 herds of cattle of N'Dama, Baoule and Zebu cross breeds in the region of Boundiali, northern Cote d'Ivoire, were monitored monthly for trypanosome prevalence, packed red cell volume (PCV), body weight and reproductive p...

In this study, the efficacies of three trypanocidal drugs, diminazene aceturate, isometamidium chloride and homidium bromide, were evaluated in four representative areas of Cote d'Ivoire with different production systems, degree of integration of different trypanosomosis control approaches and de...

Eleven groups of male cattle (39 on average per group) were monitored for presence of trypanosomes at 3-weekly intervals for periods of up to 27 weeks at a feedlot of Ferkessedougou, northern Cote d'Ivoire, in an area supposedly free of tsetse. All animals originated from or grazed during transhu...

Twelve traditional herds of cattle in the area of Boundiali, northern Cote d'Ivoire, were examined monthly from 1990 to 1992 for the presence of trypanosomes. The herds were randomised into 3 treatment groups, cattle in 4 herds received diminazene aceturate at 3.5 or 7 mg/kg body weight (b.w.) wh...
