Extract

Parasitised sheep that consumed bioactive forages, i.e. forages that contain anthelmintic compounds, showed a lower level of parasitism than sheep grazing on grass/clover pastures (Marley et al, 2003). This may be due to direct anthelmintic effects of the bioactive forages or indirect nutritional effects, e.g. mediated through an increase in protein availability. Extra protein could improve the host’s ability to mount an effective response towards gastrointestinal parasites (Coop and Kyriazakis, 1999). The aim of this experiment was to investigate whether a two-week consumption of forages that contain potential anthelmintic compounds, have a direct anthelmintic effect towards i) an established Trichostrongylus colubriformis population and/or ii) incoming T.colubriformis larvae.
