Goals Specific to Small Ruminants
• Organic approach to H. contortus control in sheep and goats
• Use of condensed tannin-rich plants to control H. contortus (sericea lespedeza and others)
• Copper oxide for H. contortus control

Goals Specific to Small Ruminants
• Rotational (mostly bermudagrass/fescue) vs. continuous (bermuda or SL) grazing
• Systems approach (combinations of techniques including FAMACHA, COWP, SL, deworming “diets”)
• Establishment of browse for goats
