Three different tick control policies were tested in groups of traditionally managed Sanga cattle in the Central Province of Zambia over a period of 3 years. One group was given strategic tick control using 12 pyrethroid acaricide spray applications

Increasing costs of tick control have necessitated a complete re-assessment of its economic impact. There are two main approaches to studies on production economics. Some researchers advocate a “systems approach” in which all production traits an

Two herds of experimental Sanga cattle were maintained under traditional savanna grazing management for three years in the Central Province of Zambia. One herd was kept free of ticks by regular acaricide treatment, while the other was given no tick c

Field trials were carried out during 1982-86 in two different ecotypes in central Zambia to determine the impact of tick control on the liveweight gain (LWG) of cattle. During the first 2 years of the trial a diamidide acaricide (Amitraz) sprayed at

In ecological studies in central Zambia, both climate and ecotype affected population dynamics of tick species. Below average rainfall for several years caused a suppression in numbers of Rhipicephalus appendiculatus Neumann adults. Reduction in rain

Summary : Pathotyping of twenty Newcastle disease virus isolates, iso lated from field outbreaks during 1982-1983 in the Republic of Zambia, was carried out. Characterisation was based on mean death time, intra cerebral pathogenicity index, intra

Summary : A review of rabies-positi ve cases between 1975 and 1982 showed that rabies occurred mainly in dogs. During this period a total of 1,384 cases were diagnosed, 1,076 (77.7%) of which were in dogs. During the same period, 280 cases occurred a
