The use of chemoprophylaxis in East African Zebu village cattle exposed to trypanosomiasis in Muhaka, Kenya

A study conducted to assess the efficacy of chemoprophylaxis for the improvement of the health and productivity of East African Zebu village cattle exposed to trypanosomiasis. Examines the cost-effectiveness of the treatment. Includes data on calf pre-weaning health and weight traits, weight traits of calves from 12-18 months of age, calf post-weaning health and weight traits, and breeding cow health and production traits - for the non-prophylactic and prophylactic groups

Evaluation of criteria of trypanotolerance

Evaluates teh criteria for trypanotolerance including three related characterstics, v.z. the ability to control parasitaemia, the ability to control anaemia, and the ability to develop an effective immune response

Trypanosomiasis in N'Dama cattle under village management in Zaire

Reports the prevalence species and intensity of trypanosome parasitaenia (1986-1987) for N'Dama cattle managed in village herds inforest and plateau areas of Idiofa, Zaire, Examines tsese challenge & its relationshipto trypanosome prevalence. Reports the duration of infection, pattern of parasitaemia and the effects of trypanosomiasis and other diseases on PCV. Gives preliminary performance data

Factors affecting trypanosome prevalence in Zebu cattle exposed to high trypanosomiasis risk in south-west Ethiopia

Determines factors affecting trypanosome prevalence in Zebu cattle exposed to high trypanosomiasis risk in south west Ethiopia. Studies the occurrence of trypanosome infection in adult cattle, monthly trypanosome prevalence in calves and cattle, prevalence in male and female adult cattle, relation between different levels of PCV in infected and unaffected adult cattle and infection rates

Trypanosomiasis in N'Dama cattle under village management in Zaire

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 on PCV was reported. Mean monthly PCV for the total population was 34.9%, with some variation between areas (forest 34.2%, plateau 35.6%) and large variation between herds (31.6 to 40.7). Mean past-partum weight of N`Dama cows in this population was 232 kg, and mean calf weights at 8 and 12 months were 88 and 105kh, respectively. These preliminary results on the health and performance of N`Dama cattle managed in village herds at trypanosomiasis risk were a good illustration of the trypanotolerance of the N`Dama

Preliminary results of a study of N'Dama cattle introduced in a metayage system in Idiofa District, Zaire

Presents preliminary results of a study of N'Dama cattle introduced in a metayage system in Zaire. Studies tsetse relative densities, tsetse challenge, corrected tsetse challenge, trypanosome prevalence and PCV in gallery forest, savanna woodland and grass savanna areas. Also presents data on feeding preferences of G. fuscipes by different animals and illustrates the effects of trypanosome infections in the dam and in the calf on weight of calf

Aspects of trypanotolerance and associations with growth rate in post-weaner N'Dama cattle under high trypanosomiasis risk

A study conducted to find out the ability of N'Dama cattle to control parasitaemia and anaemia at a ranch in Gabon. Examines the effect of parasitaemia on daily liveweight change

Genetic aspects of criteria of trypanotolerance

Discusses the genetic aspects of criteria of trypanotolerance including parasitaemia, anaemia control and immune response. Includes data on heritability estimates for daily liveweight change, for PCV under low & high trypanosome prevalence, and for number of treatments required in four periods after parturition

Economic aspects of cattle production and of chemoprophylaxis for control of trypanosomiasis in village East African Zebu Cattle in Kenya

Results of a cost-benefit analysis of cattle production and of chemoprophylaxis for control of trypanosomiasis in village East African zebu cattle in Kenya
