Discusses trypanotolerance in cattle and prospects for the control of trypanosomiasis by selective breeding in Africa. Looks into methods available for control including tsetse control, drugs & vaccination and discusses constraints that limit the control. Also discusses prospects for future contr...

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 ...

A study undertaken to evaluate the degree of genetic determination in the control of development of anaemia in N'Dama post-weaner cattle exposed to a medium natural trypanosome challenge during a short term test for trypanotolerance. The heritabilities of average pcv, lowest pcv reached, and grow...

Presents results of a study undertaken firstly to measure the relative effects in N'Dama cattle of length of time detected parasitaemic; intensity of parasitaemia; and control of development of anaemia; on reproductive performance (calving interval), maternal ability (calf weaning weight) and cow...

A paper dealing with research conducted to reduce the effect of trypanosomiasis on animal production in Africa. Looks into the African Trypanotolerant livestock Network and discusses the exploitation of trypanotolerant breeds, trypanosome prevalence and animal performance. Also examines specific ...

Evaluates the health and productivity of East African Zebu cattle under village management in a tse-tse infested area surrounding the Muhaka Forest on the Kenya Coast south of Mombassa, and assesses the cost-effectiveness of intervention with trypanocidal drugs.

A study was conducted to assess the correlation between criteria of trypanotolerance and production. N'dama post weaner cattle with different weights and from different age groups were studied for weight gain, packed cell volume (PCV) and for the presence of trypanosomes. The analysis approach wa...

Studies the efficacy of chemoprophylaxis for the control of trypanosomiasis on 700 heads of East African Zebu Cattle maintained in village herds in a tsetse-infested area at Muhaka, Coast province of Kenya. Shows the effect of trypanocidal drugs and time on trypanosome prevalence, and the effect ...
