The anthelmintic properties of tannin-rich legume forages: from knowledge to exploitation in farm conditions

Tannin-rich legume forages have nutraceutical value for ruminants through slowing down the infec- tions with parasitic nematodes of the gastro intestinal tract. This review aims to describe the effects of tan- nin-containing legumes on the various nematode stages We will also discuss the sources of variability in results and present the current hypotheses in regard to the possible modes of action of the plant secondary metabolite on the worms.
