A SYSTEMS APPROACH TO CONTROL GASTROINTESTINAL NEMATODES (GIN) IN ORGANIC SMALL RUMINANT PRODUCTION
Dale Bumpers Small Farms Research Center
2011 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 on farm by producers who will submit information on the success of approaches employed.
Development of decision tools for producers will occur and teaching modules for
farmers, educators and students will be developed and implemented.
Collection of research data is occurring so that an economic analysis can occur. Partial budget analysis will be employed to compare net revenues resulting from implementing the proposed GIN management strategies with one another and with current prevailing practices. Estimates of economic losses from parasitic worms under current practices compared to organic or grass-fed production will be developed to provide a baseline from which to evaluate net revenue changes resulting from implementing chemical free control strategies examined in the project.
The ADODR communicated with UA at meetings (November 2010, Booneville, AR) and by weekly email and phone conversations.
