Over the last two to three decades, West Africa has witnessed considerable changes in land use. Unprecedented increases in human population combined with changes in climatic patterns have reduced per capita arable land traditionally available for agricultural production. In the livestock sub-sect...

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 fee...

Ranch organization and animal health management

Approximately 90 village Ethiopian Highland Zebu cattle at Gullele in southwest Ethiopia were ear-tagged in March 1986 and they and their offspring monitored monthly until February 1996. In January 1991 a tsetse control campaign began using a synthetic pyrethroid cypermethrin pour-on applied mont...

Methods for determining the efficacy of animal health interventions involving vector-borne diseases when the intervention attempts to control the vector itself are described. There are a number of possibilities. For example, a before/after study can be undertaken when data collected following the...
