American Consortium for Small Ruminant Parasite Control Investigations on the Use of Plant Secondary Compounds of Sericea Lespedeza for the Control of Sheep and Goat Parasites

Abstract

<p><strong>Introduction</strong>: Sericea lespedeza (SL; <em>Lespedeza cuneata</em>) is a warm-season perennial legume well-adapted to the warm, moist climate of the southeastern USA. High in condensed tannins and other secondary compounds, SL has potential as an anti-parasitic nutraceutical forage for sheep and goats in this region and throughout the world where it is adapted. <strong>Objectives</strong>: To summarize the nearly 20 years’ work of the American Consortium for Small Ruminant Parasite Control (ACSRPC) related to the anti-parasitic properties of SL in the diet of small ruminants. <strong>Results</strong>: In a series of experiments with goats and sheep fed SL in fresh (grazed), dried (hay, leaf meal, pellets) or preserved (ensiled) forms, this forage showed promising anti-parasitic efficacy against GIN, particularly <em>Haemonchus contortus</em>, and coccidia (<em>Eimeria </em>spp.), lowering gastrointestinal nematodes (GIN) fecal egg counts (FEC), coccidial fecal oocyst counts (FOC), and reducing GIN larval development and worm burdens. <strong>Implications</strong>: These results indicate the potential of SL as a component of integrated, novel (non-chemical) parasite management programs for on-farm application by small ruminant producers. <strong>Conclusions</strong>: Sericea lespedeza has very good anti-parasitic activity against GIN and coccidial infection in sheep and goats and has excellent potential as a nutraceutical forage for small ruminant producers, either for their own use or for sale as nutraceutical hay or pellets.</p>
