The mission is to develop technology and scientific principles to enhance profitability and sustainability of small farms.
NP-205 Program: Management of southeastern grazing lands and livestock to optimize small farm
sustainability
• Develop grazing systems for niche meat production
• Develop quality forages that bridge the summer gap
• Etc.
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
