Presents findings of a research carried out into the factors associated with genetic resistance to parasitic diseases in livestock Development projects in tsetse-infested areas of Africa. Indicates that trypanotolerant breeds of domestic livestock are capable of making a contribution towards alle...

Host response of some African wild bovidae to experimental trypanosome infection
Mkwaja Ranch is located on the coast of Tanzania in Pangani District about 100 km south of Tanga. The ranch covers an area of 47,250 hectares of coastal forest-savanna mosaic vegetation. The area is heavily infested with three species of tsetse, Glossina morsitans morsitans, G. pallidipes and G. ...

Productivity of Boran cattle maintained with chemoprophylaxis under high tsetse challenge at Mkwaja ranch in Tanzania. 1. Ranch organization and animal health management
This article attempts to evaluate the current state of knowledge on questions such as, to what extent is inheritance important and how is it influenced by environmental factors; what are the mechanisms underlying increased resistance; and how productive are these breeds under various levels of ch...
Evaluates the productivity of grade Boran cattle maintained by chemoprophylaxis under severe trypanosomiasis risk at Mkwaja ranch, Tanzania; uses data based on more than 20,000 calving records over the 10-year period from 1973 to 1982; discusses environmental influences on performance traits and ...

Productivity of Boran cattle maintained by chemoprophylaxis under trypanosomiasis risk
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...
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...

Quantitative phenotyping of N'Dama cattle for aspects of trypanotolerance under field tsetse challenge
Evaluates in detail how environmental and stress factorts affect trypanosome infection in N'Dama cows and their calves, the linkages with curative drug treatment given under the management regime prevailing, the linkages with anaemia control as measured by packed red cell volume (PCV), and the re...
