Comparison of experimental trypanosomosis in some breeds of sheep and goats in Burkina Faso.
To compare their susceptibility to trypanosomosis 24 West African Dwarf (WAD) sheep and goats, and 16 Sahelian Fulani (SF) sheep and goats were inoculated with strains of Trypanosoma vivax and T. congolense. One animal from each breed was used as a control. Anaemia was observed in all inoculated animals. In the group of animals inoculated with T. vivax, 1 of 6 WAD goats, 3 of 4 SF goats and 2 of 4 SF sheep died within the experimental period of 16 weeks. One SF sheep out of 4 died among animals inoculated with T. congolense. During a period of 8 weeks, no significant difference was observed between the WAD and SF breeds in the decreases in their body weight and leukocyte counts. The results showed the better resistance of sheep and goats to infection by T. vivax, whereas there was no significant difference between all the sheep and goats inoculated with T. congolense.
