Genetic aspects of control of anaemia development in trypanotolerant N'Dama cattle

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 growth on test, and the genetic correlation between the two pcv measures and growth, were estimated to indicate whether selection for control of development of anaemia could be a feasibile undertaking.
