    Proposal abstract:

    Alternatives to chemical (anthelmintic) control of gastrointestinal nematodes (GIN) in small ruminants is needed to improve viability of this industry for small and limited resource farmers in the southern USA, Puerto Rico and the US Virgin Islands. Use of plant-based solutions, including rotational grazing, feeding or grazing of condensed tannin (CT)-containing forages, and utilization of larval migration patterns in different forage types, have shown promise in controlling parasitic nematodes of small ruminants. Research staff, Extension personel, and farmers from throughout the southern USA, Puerto Rico, and the US Virgin Islands will meet for several planning meetings leading to development of a full SARE R&E proposal concerning sustainable, plant-based GIN control systems for limited resource sheep and goat farmers throughout the Southern-SARE region.

    Project objectives from proposal:

    Objective 1 - To assemble a multi-disciplinary, multi-institution, multi-state team of researchers, extension personnel, commodity leaders, and farmers to discuss, prioritize, and plan a field-based research program using bioactive forages and other forage/grazing strategies for sustainable control of small ruminant GIN in the Southern US.

    Objective 2 - To develop an education and outreach plan to effectively share research results and prepare informational materials for appropriate clientele groups throughout the Southern-SARE region.

    Objective 3 - To develop a full R&E proposal for submission to the Southern-SARE Program in 2005.
