Comparison of the effects of African trypanosomiasis in four breeds of dairy goats.

The consequences of experimental infection with Trypanosoma congolense and later superinfection with T brucei were compared among four breeds of goats: Toggenburg, Nubian, Alpine and Saanen. No major differences were found with regard to packed cell volume, bodyweight or parasitaemia. When these four breeds were considered for introduction into areas having African trypanosomiasis, none appeared to have a comparative advantage with regard to innate resistance to trypanosomes.
