Research Project: Use of Natural Strategies to Alleviate Enteric Pathogens in Organic Poultry

Location: Poultry Production and Products Safety Research

Project Number: 6022-32000-011-26
Project Type: General Cooperative Agreement

Start Date: Sep 01, 2011
End Date: Jul 30, 2015

Our 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 are: Specific research objectives for University of Tennessee are to provide expertise in using 16S rRNA gene sequencing to support the: 1. Evaluation of the effectiveness of management strategies to prevent and control enteric pathogens in organic poultry; and 2. On-farm testing of effectiveness of treatments and strategies against enteric pathogens in organic poultry production systems.

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.
