Trypanotolerant livestock are the subject of a video brought out jointly in English and French by Dr C.Hoste, with financial support of FAO (Food and Agriculture Organization of the United Nations), the CTA, ILRAD (International Laboratory for Research on Animal Diseases), and ILCA (International Livestock Centre for Africa). 'Trypanotolerant livestock: the key to livestock development in Africa' is the title of the film, and it attempts to point out clearly the advantages of these animals in developing African livestock production. SPORE 17 (Nov '88) explored the problem of animal trypanosomiasis in Africa, and outlined the steps to be taken to combat the disease: elimination of the tsetse fly vector; immunisation or treatment of cattle against the disease; and finally the use of trypanotolerant cattle - that is, those which are resistant or quasi-resistant to it. Two possible methods of achieving this have emerged - first, to continue rearing native or foreign breeds which are susceptible to the disease. This involves either an all-out war on the vectors of the disease, or the use of chemotherapy or chemoprophylaxis - or, more usually, a combination of the two. The alternative is to breed native trypanotolerant breeds. A comparative study of these two solutions would be extremely complex and answers to some questions, involve political rather than technical choices. However, up till now, more effort has been put into the campaign against vectors and the chemotherapy/ prophylaxis solution than on breeding trypanotolerant varieties. The most obvious reason for this is that trypanotolerant animals are smaller and seemingly less productive than the exotic breeds. It was not till the 1950s that there was any major transfer of trypanotolerant strains from West to Central Africa, and it was only at the end of the Seventies that the publication of a major study by ILCA, FAO, and UNEP suggested that the development of trypanotolerant cattle might benefit animal production in tropical Africa. It is still necessary to correct the notion that the small stature of the trypanotolerant cattle necessarily means reduced productivity or draft potential. The many studies carried out on this subject have proved that these preconceptions are unfounded, and that trypanotolerant breeds have a major contribution to make. This video fully supports this view. It comes with a booklet which puts it clearly in the context of 'The campaign against African animal trypanosomiasis and the development of affected zones'. This booklet also contains supplementary information which could be used for discussion purposes after seeing the film. Both film and booklet are available from all four organisations involved in the project
