Journal Article 1991

Autor: Trail, J.C.M. D'Ieteren, G.D.M. Maille, J.C. Yangari, G. Nantulya, V.M.

Evaluates possible contributions of the antigen-detection enzyme immunoassays (ELISA) for the diagnosis of Trypanosoma vivase, T.congolense, and T.Bucei infections in N'Dama cattle in Gabon, Central Africa. The assays are based on monoclonal antibodies which recoginse trypanosome antigens specifi...

Autor: Trail, J.C.M. D'Ieteren, G.D.M. Maille, J.C. Yangari, G.

A study undertaken to evaluate the degree of genetic determination in the control of development of anaemia in N'Dama post-weaner cattle exposed to a medium natural trypanosome challenge during a short term test for trypanotolerance. The heritabilities of average pcv, lowest pcv reached, and grow...
