Research Profile

The primary focus of Dr. Butcher’s extension program involves providing technical support to the Florida Poultry Industry and related avian industries. Activities include on-farm visitations, poultry necropsies and sample evaluations (histopathology & serology), and consultations. The program at the University of Florida is primarily to provide direct support to the industry in Florida; however, international work in support of IFAS’ International Programs Mission and the University’s Mission toward globalization is undertaken. A statewide Salmonella monitoring program has been developed in association with the Florida Poultry Federation. This proactive program permits identification of Salmonella-infected farms and provides recommendations on eradication procedures. Research efforts have been directed toward recombinant vaccines to combat poultry diseases including Newcastle disease, Gumboro disease, Marek’s disease, and infectious laryngotracheitis. Vectors have included virus and plants. Work is also being conducted on transgenic chickens.
