ABSTRACT
In the Western Province of Zambia, a productivity study was carried out in traditionally managed cattle herds. The organisational design of the study and the procedures involved in the management of the data are described. Some possibilities of use of the data are discussed.

A trypanosomiasis survey was conducted in South-West Zambia. From a total of 3,346 cattle sampled 342 cattle showed a positive trypanosomiasis parasitaemia. During the survey trypanosome species and PCV values were also recorded. With simple statistical analysis populations with higher and lower prevalence rates were differentiated. The results indicated that the Kwando River Basin Tsetse Fly Belt and the Kafue River Basin Tsetse Fly Belt infested a larger area than originally assumed and that a link-up between both belts occurred or will occur in the near future.

The supernatant obtained after centrifugation of an emulsion of engorged female Amblyomma astrion ticks, collected from cattle on the West African island of São Tomé, was injected intravenously into a goat, which contracted heartwater. This confirmation of the existence of the disease on the island makes strict control measures necessary if present efforts at improving livestock production by imported exotic cattle are to be successful.
