Determination of tsetse challenge and its relationship with trypanosome prevalence in trypanotolerant livestock at sites of the African Trypanotolerant Livestock Network

Reports the determination of tsetse challenge at sites of the African Trypanotolerant Livestock Network and its relationships with trypanosome prevalence for the period 1984-1986. Lists the Network sites with trypanotolerant cattle or sheep together with the tsetse species detected. Discusses tsetse species captured, tsetse relative density, trypanosome infection rates and infection types in tsetse, and tsetse challenge and trypanosome prevalence in trypanotolerant livestock

Determination of tsetse challenge and its relationship with trypanosome prevalence in livestock within the African Trypanotolerant Livestock Network

Determines the tsetse challenge and its relationship with trypanosome prevalence in livestock at eleven sites within the African Trypanotolerant Livestock Network. Includes tsetse species, their distribution, habitats, and relative density; trypanosome infection rate; and frequency of vivax and congolense - type infection; also shows the overall tsetse challenge determined from the product of relative density; and tsetse challenge and trypanosome prevalence for trypanotolerant and other cattle herds

Relationships between tsetse challenge and trypanosome prevalence in trypanotolerant and susceptible cattle

Reports results of a study on the relationships between tsetse challenge and trypanosome prevalence in trypanotolerant and susceptible breeds of cattle. Presents data on tsetse challenge and trypanosome prevalence in N'Dama and Zebu cattle in Zaire, Gabon, Ethiopia and Cote d'Ivoire

Tsetse feeding habits and tsetse challenge at sites of the African Trypanotolerant Livestock Network

Reports the feeding preferences of Glossina species at sites of the African Trypanotolerant Livestock Network. Estimates tsetse challenge and relates the results with trypanosome prevalence in cattle. Examines the relationship between tsetse challenge using linear regression analysis. Also examines the difference between the slopes of the regression lines obtained for trypanotolerant and susceptible cattle using a 't-test'

Genetic and environmental factors affecting trypanosome prevalence and parasitaemia in livestock

Presents results of a consolidated study on genetic and environmental factors affecting trypanosome prevalence and parasitaemia in livestock from the ten sites of the African Trypanotolerance Network. Includes data on prevalence in sheep, goats and cattle, prevalence in three age classes of cattle, sheep, prevalence of female physiological-status classes in cattle, prevalence when gestating and not gestating

Trypanosome infections and other factors influencing PCV in livestock

Reviews some of the important factors influencing PCV value in livestock in six network sites. Includes data on the effect of no. of months with trypanosome parasitaemia on PCV in Djallonke sheep, pre-aand pos-partum on ewe PCV during lactation, on PCV of cattle, on PCV of N'Dama cattle; and PCV pre-weaning of male & female progens
