Journal Article 1995

Quantification of the relative importance of trypanotolerance measurements on productivity of N'Dama cattle (Addendum)

Autor: Wissocq, N.M. D'Ieteren, G.D.M. Trail, J.C.M. Kakiese, O.

Matching information on animal health and performance aspects was collected from 255 N'dama post-weaners from September 1986 to December 1991. Records covered for each animal a two years period from weaning at 10 months of age until 34 months of age. Curative trypanocidal drug treatment was given...

Journal Article 1984

Genetic resistance to animal trypanosomiasis in Africa

Autor: Murray, M. Trail, J.C.M.

Examines the genetic basis of trypanotolerance with particular reference to Africa, environmental factors which can influence its stability like age, stress (work, pregnancy etc.), nutrition and disease, and the possible mechanisms responsible; looks at the tyrpanotolerance of different breeds.
