Agricultural expansion is a major cause of biodiversity loss worldwide. In Africa, biologists have observed that the populations of some tsetse species, which transmit human and livestock trypanosomosis, decline or disappear as human populations grow and farmers clear fly habitat for cultivation....

Trypanosomiasis is one of the most important diseases in African cattle. About 3 million cattle die every year by this disease. However, about 5 percent of the total African cattle have a natural resistance against trypanosomiasis. In a preliminary study markers linked to trypanotolerance have be...

To formally quantify the level of under-detection of Trypanosoma brucei rhodesiense sleeping sickness (SS) during an epidemic in Uganda, a decision tree (under-detection) model was developed; concurrently, to quantify the subset of undetected cases that sought health care but were not diagnosed, ...

This study was conducted to (i) determine the prevalence of African Animal Trypanosomosis (AAT) in tsetse challenged areas, (ii) compare conventional with qPCR detection systems and (iii) evaluate the host genetic background and biology as risk factors. AAT prevalence studies are often confronted...

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...

A deltamethrin `pour-on' insecticide was applied monthly to over 2000 cattle exposed to a high challenge of drug-resistant trypanosomes and high tsetse re-invasion pressure in the Ghibe valley, south-west Ethiopia. Blood samples were taken monthly from an average of 760 cattle for determination o...

Discusses the general prospects for demand and supply of meat and dairy products in tropical Africa, w. emphasis on factors influencing supply & demand such as population growth, rising incomes, and traditional production blockages. Analyses supply prospects from existing livestock production sys...

The effects of trypanosomiasis and production of zebu, N'Dama and Muturu cattle in tse-tse infested areas are investigated. Observations on parasitaemia, blood values, body weight and clinical condition included. The zebu, N'Dama and Muturu cattle showed relative resistance to infection with try...

Historical account of the introduction of trypanotolerant cattle breeds to Zaire. Successes achieved under good feeding and management conditions on both large and small farms highlighted. Current developments in N'Dama cattle breeding in the region and their extension to the new land areas revie...
