ABSTRACT
Chemotherapy and prophylaxis can cope with temporary risks linked with animal trypanosomiasis. It would be a mistake to undertake campaigns to allow introduction of zebu cattle in presently tse-tse flies infested areas. On the contrary, trypanotolerant cattle should be favoured in such areas as it is now proved that they are more productive through their light body weight than the larger zebus. In this context the dwarf Guinean goat and Djallonke sheep deserve also more consideration, as well as the potentialities offered by rational use of wild animals in a given situation. Tse-tse eradication programmes are not trustworthy as sustained success is extremely rare. Simple and cheap techniques to control the fly population should be further studied and used extensively. More financial resources should be made available for investigation on the mechanisms of trypanotolerance, and to multiplication of trypanotolerant breeds if required. A fair and unbiased analysis of each situation should be undertaken on merit basis without any preconceived ideas with due consideration on the conservation of the environnement.
