Approximately 390 East African Zebu calves from birth to 3 years of age and their dams 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. Cattle were individua...

Effects of trypanosomiasis on growth and mortality of young East African Zebu cattle exposed to drug-resistant trypanosomes
The genetic components of trypanotolerance measurements must be determined in well controlled on going production systems where the necessary identification and/or quantification of environment and genetic effects are possible. A resource population has been established in the Mushie District Ban...

A N'Dama cattle resource population for research on trypanotolerance
Emphasises the importance of trypanotolerance by indicating that trypanotolerant breeds were at least as productive as other indigenous African breeds in areas of zero to low tsetse challenge and that in areas where tsetse challenge was substantial, only trypanotolerant breeds could survive. It w...

Characterisation of trypanotolerant cattle: a case study
The objective of this study was to apply transition models to distinguish between factors associated with both incident and persistent trypanosome infections. Data collected from 1561 cattle were analyzed from a long-term study involving 8 herds in which both trypanosome infections (a total of 56...

Interviews with all the households in the Agropastoral Zone (ZAP) of Yale, southern Burkina Faso, were conducted in 1994 and again in 1997 to assess the impacts of a tsetse control programme implemented from 1994, using insecticide-impregnated targets and pour-on treatments of all cattle with del...

Data on tsetse fly, and on village Ndama cattle collected over a 4-year period in southern Senegal were analysed. A total of 431 Ndama cattle in four herds of three villages in the Upper Casamance area of southern Senegal were monitored monthly. Glossina morsitans submorsitans and Glossina palpal...

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...

Estimating the effects of tsetse control on livestock productivity - a case study in southwest Ethiopia
Trypanosomiasis is one of the major constraints on animal production in areas of Africa that have the greatest potential for significant increases in domestic livestock populations and livestock productivity. While various methods are being used by farmers to control the disease, major public eff...
