Thirty-six African countries are directly affected by trypanosomiasis, which is transmitted mainly by : glossina (tsetse) flies.These flies occur over an estimated 10 million square kilometres, or roughly one-third of the African continent. A review by the FAO concluded that, but for the existence of this disease, current levels of cattle-breedina could be raised by 120 million head throughout all the infested areas which have plentiful fodder and water resources. In approximate terms, this would allow the doubling of livestock production throughout tropical Africa. It is possible, though time-consuming and costly, to eliminate the flies that are the vectors of the disease and to use prophylactic or curative drugs to protect animals from the disease. A third alternative is to make wider use of breeds of livestock which are completely, or partially, tolerant of animal trypanosomiasis. FAO have produced a video, Being a breeder today, to promote a greater awareness of the trypanotolerant breeds of livestock, such as the N'dama and West African Dwarf Shorthorn cattle and a number of breeds of sheep and goats. All of these breeds originate in West Africa and so the film was made in the Gambia, Guinea and Senegal. Livestock owners and extension staff discuss the advantages and disadvantages of trypanotolerant breeds and the video can be used to support training in production, breeding and feeding of livestock and choice of breeds. Trypanotolerant cattle tend to be smaller than non-tolerant breeds and this has usually been viewed as a disadvantage. However, the video makes clear that, despite their smaller size, trypanotolerant breeds make excellent draught animals and are as productive as milk and meat animals as larger breeds, sometimes more so. Usually there is no advantage gained in cross-breeding a small trypanotolerant animal to a larger non-tolerantbreed: the degree of protection may be reduced substantially without an, gain in productivity. The video also demonstrates the benefits of forming Breeders Associations: these car provide opportunities for exchange of information and experience between members. Several of those featured in the video testity to increased income from improved management practices including better feeding and regular disease prevention measure! such as dipping and spraying against ticks and vaccination. CTA is funding the copying and distribution of the video which is available to ACP nationals engaged in livestock manage meet. For further information write to CTA.
