Research Project: A Systems Approach to Control Gastrointestinal Nematodes (Gin) in Organic Small Ruminant Production

Location: Dale Bumpers Small Farms Research Center

2012 Annual Report


1a.Objectives (from AD-416):
The objectives are to examine farm management systems for year round gastrointestinal nematode control, identify resistant animals to minimize problems with nematode infection, conduct on-farm studies on the feasibility of techniques developed from research studies, and educate outreach professionals and producers on adopting available organic gastrointestinal nematode control strategies in small ruminants by disseminating state-of-the-art knowledge and procedures.


1b.Approach (from AD-416):
The impact of continuous use of integrated methods that have been developed by these investigators previously will be examined using a systems approach in a long term experiment. Forage systems, including birdsfoot trefoil, will be examined to minimize parasite infection. Integrated approaches described above will be examined on-farm by producers who will submit information on the success of approaches employed.


3.Progress Report:

An experiment is being conducted in upper Michigan on a farm to examine the use of birdsfoot trefoil, a plant high in condensed tannins, in a pasture system for sheep to aid in the control of parasitic worms. Research on parasite control is widely disseminated through extension activities: Integrated parasite management program (3 sessions [Southeast, Southwest and North Michigan]; 108 participants): 6-hour program on parasite management with an emphasis on integrated approaches, including infection monitoring, chemical treatment strategies, grazing management and understanding animal susceptibility. Students learn through lecture, discussion, quantitative fecal egg counting lab, and FAMACHA training on a local farm.
