Le materiel informatique du CIPEA et son utilisation
Examines some of the problems encountered and provides information on computer networking and the potential of computers in livestock research; describes the ILCA computer facility and the services which ILCA provides to national research organizations that do not have computer facilities
The trypanotolerance network. 2. A study on health and productivity of N'Dama, Nguni and their crosses under quantified levels of tsetse challenge in Gabon. 2.1. - Tsetse survey
Examines the proboscides, midguts and salivary glands of live tsetse species for trypanosomes trapped at forest edges, inforest close to watercourses and at the boundaries of savanna and pastures in Gabon to confirm the existence of a considerable trypanosomiasis risk due to the high infection rate encountered in cattl
The trypanotolerance network. 2. A study on health and productivity of N'Dama, Nguni and their crosses under quantified levels of tsetse challenge in Gabon. 2.2. - The influence of trypanosomiasis on the health status and performance
Presents two different methods of treatment of trypanosomiasis, prophylaxis and therapeutic treatments, for N'Dama cattle, Nguni cattle and their crosses in Gabon; monitors the recording of packed cell volume percent (PCV), trypanosome detection and bodyweight estimation; and studies animal health and reproduction parameters
The trypanotolerance network. 1. Objectives, organization and current activities
Evaluates the productivity of different breeds of cattle, sheep and goats, particularly trypanotolerant breeds, exposed to different degrees of tsetse challenge under various management systems in 9 West and Central African countries and in three associated East African countries, w. the objectives of improving livestock production in tsetse infested areas
Selection in trypanotolerant cattle breeds in Africa
Presents results of experiments to determine phenotypic & genotypic relationships of the abilities to control parasitaemia, resist anaemia or develop an immune response with animal performance in terms of daily weight gain, maintenance of packed cell volume levels and disease prevalence in trypanotolerant N'Dama and Sahiwal/Ayrshire cattle at three locations in Africa. Assesses heritability of each trypanotolerance-inducing characters
Efficacy of chemoprophylaxis for East African Zebu cattle exposed to trypanosomiasis in village herds in Kenya
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 of trypanocidal drugs and parasitaemia on blood packed cell volume (PCV) and on daily liveweight chang
Trypanosomiasis in N'Dama cattle in Zaire and its effects on their health and production
Reports the prevalence, species and intensity of trypanosome infections over a 3 year period for N'Dama cattle managed on Mushie Ranch, Zaire. Presents the effects of the trypanosome infections on blood packed cell volume reproductive performance and liveweights
Can PCV be used as an indicator of trypanosomiasis and production level in cattle?
Results of a study conducted to estimate the importance of factors influencing blood packed cell volume (PCV) and to investigate possible relationships between PCV and reproductive & liveweight performance of N'Dama cattle exposed and not exposed to trypanosomiasis under the same system of management on two ranches in Zair
Comparative performance of trypanotolerant and more susceptible cattle breeds exposed to trypanosomiasis in Gabon
Reports the influence of breed and animal age on the prevalence, species and intensity of trypanosome infection and the effects of the infections on the blood packed cell volume (PCV) of N'Dama, Nguni and crossbred cattle. Presents the effects of trypanosome infection, PCV level and lactational status on reproductive performance and liveweight of N'Dama cattle. Compares the mortalities of different breeds exposed to trypanosomiasis risk
Effect of endemic diseases including trypanosomiasis on the blood packed cell volume of livestock in northern Ivory Coast
Studies trypanosome infections and other anaemia producing pathogens in cattle and sheep maintained in village herds and flocks at network sites of Boundiali and tengrela in northern Ivory Coas
