Progress 11/06/14 to 07/12/18
Outputs
Target Audience:The target audience for this project included commercial and non-commercial poultry producers, extension poultry specialists, extension educators, avian veterinarians and poultry service providers. Changes/Problems:The project end date was changed to 7/12/2018, to terminate the project early due to Project Director's retirement. What opportunities for training and professional development has the project provided?
Nothing Reported
How have the results been disseminated to communities of interest?For my part of the project I have met with individual producers in my role as Extension Poultry Specialist and provided them with information on the use of LED lamps for their poultry and also discussed the use of pro-biotics and PDA's as nutritional supplements for their birds. I have also made presentations at The National eqq Quality School where 55 participants learned about the role of PDA's in controlling Salmonella in their laying hens. I also presented information on energy efficient lighting and the use of LED lamps at the Aviagen International Poultry Management School. I have also met with veterinarians in the area to discuss the impact of the VFD on poultry producers and what alternatives they have. Also, through 9 other extension education meetings with small poultry flock owners I provided them with information on proper housing, nutrition, lighting, biosecurity and other areas covered under goals 1, 2 and 3 for the project What do you plan to do during the next reporting period to accomplish the goals?
Nothing Reported
Impacts
What was accomplished under these goals?
Plant Derived Antimicrobials (PDAs) were found to control the growth of Salmonella enteritidis (SE) in meat chickens, on meat from chickens and on eggshells. The PDAs were also found to control SE in laying hens and to control aflatoxin growth and toxicity in poultry feed. LED lights placed in individual cages of laying hens in a commercial colony cage facility improved egg production in the bottom row of cages compared to bottom rows without the lamps.

What do you plan to do during the next reporting period to accomplish the goals?I plan to continue working on adopting LED technology to the poultry industry and collaborating with other researchers, veterinarians, and extension educators on the use of PDA's in controlling SE and aflatoxins in poultry and poultry feed and help poultry farmers reduce the use of other antibiotics in poultry as a result of the Veterinary Feed Directive.
Impacts
What was accomplished under these goals?
Poultry producers are switching from incandescent or fluorescent lamps to more energy efficient LED lamps. This is resulting in energy savings, less demand on the electrical grid, and monetary savings for the producers. Payback for installing LED lamps can be as short at six months for some producers. When the Veterinary Feed Directive (VFD) became law poultry producers looked for alternatives to antibiotics to keep their flocks healthy and growing efficiently. Many are now turning to pro-biotics and different essential oils (or Plant Derived Antimicrobials, PDA's) that can be added to the poultry feed. As a result of our project and related research poultry producers have alternatives to antibiotics.

What opportunities for training and professional development has the project provided?Project members had the opportunity to visit Switzerland and learn about their poultry production system, how it is modeled and regulated. We were able to visit a typical aviary system with winter porches and outside access to see how it affected bird health and welfare. Growing pullets under the same conditions as they will be exposed to as laying hens is a critical aspect of their production system. How have the results been disseminated to communities of interest?Information on both the use of PDA's for SE and aflatoxing control was disseminated at twelve small flock owner meetings that averaged 40 people in attendance. It was also provided to several hundred small poultry flock owners via email communication. This information was also presented at the Aviagen International Poultry Management School and at the National Egg Quality School and also at the Poultry Respiratory Disease Coordinated Agricultural Project conference. Information was also provided to members of the Connecticut Poultry Association through their regular meetings and via email communications. What do you plan to do during the next reporting period to accomplish the goals?I plan to continue working on adopting LED technology to the poultry industry and collaborating with other researchers and extension educators on the use of PDA's in controlling SE and aflatoxins in poultry and poultry feed and help poultry farmers reduce the use of other antibiotics in poultry as the Veterinary Feed Directive becomes effective.

How have the results been disseminated to communities of interest?Information about the use of plant-derived antimicrobials (PDAs) in controlling Salmonella was provided to many small flock producers and several small flock owner seminars held in Connecticut. What do you plan to do during the next reporting period to accomplish the goals?Keep up the research on the PDAs on Salmonella control and also look at the effect of PDAs on control of aflatoxins in poultry. Finish data collection on the use of LED's within cages of laying hens to determine their effect on production and welfare. Workshops and seminars on use of plant derived antimicrobial agents for control of Salmonella enteritidis will be held for poultry producers, extension poultry specialists, avian veterinarians, USDA officials and others interested in the control of Salmonella enteritidis in poultry. Fact sheets will be developed and distributed both in person and as downloads available from websites on the use of plant derived antimicrobials for the control of Salmonella enteritidis in poultry. Fact sheets will be developed and distributed both in person and as downloads available from websites on the use of LED and other energy efficient lighting systems for poultry. Workshops and seminars on the use of LED and other energy efficient lighting systems for poultry will be held for poultry producers, extension poultry specialists, and poultry servicemen.
Impacts
What was accomplished under these goals?
Plant Derived Compounds were found to control the growth of Salmonella on egg shells of fertile eggs in incubators and on non-fertile eggs. LED lights have been installed within each cage in a lower cage row in a commercial layer facility to determine how the supplemental lighting in the darkest part of the layer facility would affect egg production and hen welfare.
