Nematode parasites are considered one of the main health problems, affecting small ruminant's production worldwide due to their resistance to the commercial anthelmintics. Wattle tannin has been used as an alternative strategy for control. However, concentrations and frequencies can likely influence tannin effect on parasites control. The aim of this book was to determine the degree of pasture infestation and nematode infection in sheep and goats, nematode resistance to some of the anthelmintics and the potential of wattle tannin in nematodes control.
