Extract

Increasing resistance to anthelmintic drugs (Waller, 2003) has increased the need for the development of alternative methods of worm control. The antiparasitic properties of condensed tannins have been evaluated in small scale experimental trials (Athanasiadou et al. 2000) with positive effects obtained under restricted feeding regimes. However, Dawson et al. (2004) did not observe significant effects on strongyle faecal egg counts through the inclusion of 80 g tannins/kg fresh concentrate offered to lambs at grass in the period from weaning to slaughter. The aim of the current study was therefore to evaluate the effect of increased levels of tannin inclusion offered to lambs from six weeks of age on grass-based systems on faecal egg counts.
