Reproductive performance, mortality, growth, and culling and replacement rates based on 20000 calving records were evaluated for grade Boran beef cattle maintained with trypanosomiasis risk in Tanzania. Under ranching conditions, over a 10-year period in this area of high Glossina moistens morsi...

This study has indicated that differences in susceptiblity to Trypanosoma congolense infection exist among the 3 main breeds of goats in Uganda namely, Kigezi, Mubende and small East African (SEA). The Kigezi goats appeared to be the most susceptibe suffering more severe anaemia, greater retardat...

Matching animal health and performance data were recorded over the 2 year period from weaning at 10 months of age on 225 N'Dama cattle in a high natural tsetse challenge situation in Zaire. Four parameters that are regarded as possible indicators of trypanotolerance, species of trypanosomes detec...
