Progress Report Objectives (from AD-416): The overall goal is to study the effectiveness of natural strategies in the control of enteric problems such as necrotic enteritis and Salmonella and Campylobacter infection and promote gut health in poultry raised under organic conditions, while assisting organic poultry producers to comply with the requirements of the National Organic Program. Specific research objectives for the University of Connecticut are: 1. Evaluate the effectiveness of management strategies to prevent and control Salmonella in organic poultry and 2. Conduct on-farm testing of effectiveness of treatments and strategies against Salmonella in organic poultry production systems. The results of the project and information on organic poultry production in general, will be disseminated to the organic and sustainable agriculture communities by an extension team composed of experienced poultry specialists and stakeholders who have been involved in organic poultry production. The outreach/extension objectives of this proposal are to: 1. Disseminate results of the project to the organic poultry community, through numerous delivery methods including conferences, electronic and printed materials, and training activities in a research and teaching oriented organic poultry facility; 2. Conduct outreach to organic poultry producers, avian health professionals, extension specialists and other interested stakeholders regarding the objectives and results of this project; 3. Measure the impact of outreach in reducing enteric pathogens and foodborne pathogens in organic poultry production. Approach (from AD-416): As part of a USDA Organic Research and Extension Initiative funded proposal research and extension objectives will be conducted in cooperation with collaborators from the ARS Unit in College Station (Byrd) , University of Arkansas Fayetteville, University of Connecticut, Appalachian State University, University of Tennessee, Penn State University, University of Arkansas Pine Bluff and the University of Kentucky focused on a comprehensive approach to reduce pathogen and disease sources in organic poultry production systems. Caprylic acid (CA) is a natural, fatty acid present in bovine milk and coconut oil, and is an FDA-approved food-grade compound. Trans-cinnamaldehyde (TC) is also a food-grade compound naturally present in cinnamon oil. Our preliminary research indicates that CA and TC are bactericidal on Salmonella and Campylobacter, highlighting the potential of CA and TC as new tools to control these pathogens in organic poultry. In addition there is evidence that these compounds may reduce necrotic enteritis in birds and a disease model will be used to assess this approach. In addition treating birds and the litter with natural products such as these essential oils, probiotics and bacteriophage will also be assessed. This project, funded through the Organic Agriculture Research and Extension Program, NIFA, USDA, is a collaborative effort with the University of Connecticut. Studies are being conducted on using combinations of natural plant compounds and lactose (natural milk product) , and management approaches customized for organic production; our objective is to develop comprehensive strategies to eliminate enteric diseases (necrotic enteritis) and foodborne bacterial contamination (Salmonella and Campylobacter) in organically raised poultry. Research is currently being conducted under Research Objective 3, Reduce the incidence of foodborne pathogens including Salmonella and Campylobacter in organic poultry production. We have completed trials evaluating the effect of therapeutic supplementation of plant compounds, trans- cinnamaldehyde and eugenol, on Salmonella enterica serovar Enteritidis colonization in market-age broiler chickens. A manuscript is published.
