Extract

Tse-Tse flies inhabit over 11 million km2 of Africa and are vectors of trypanosomes which cause trypanosomiasis in domestic livestock. The disease has a negative effect on productivity and is fatal in non tolerant breeds. The effect of nutrition on response to the disease was studied.

Thirty two N'Dama heifers (initial mean liveweight 113 + 17.0) were offered ad libitum andropogon hay plus 10.2 g/kg LW groundnut hay (GNH) (L) or GNH and 3.9 g/kg LW groundnut cake (GNC) (H). After 4 weeks on diet, half of each group were inoculated intradermally with trypanosomes (T. Congolense) (LI and HI). Intake was measured daily and liveweights weekly, while thrice weekly blood samples were examined for parasitaemia and packed cell volume (PCV).
