USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at the University of Georgia in Athens, Ga., in which a researcher showed how infectious laryngotracheitis (ILT) can spread from vaccinated flocks. The research was made possible in part by an endowing Foundation gift from Claxton Poultry and is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A brief summary of the completed project is shown below. A complete report may be obtained by going to USPOULTRY’s website, www.uspoultry.org. The project summary is as follows.
Project #699: Does broiler vaccination with HVT-LT (INNOVAX) vector vaccine increase the infectious laryngotracheitis virus challenge infectious dose?
(Dr. Maricarmen Garcia, University of Georgia, Athens, Ga.)
Dr. Maricarmen Garcia, at the University of Georgia, recently completed a research project that studied how well a recombinant ILT vaccine protected broilers when various doses of the vaccine were used. She found that all dosage levels used protected against the clinical signs of the disease, but none of the dosage levels prevented the broilers from shedding the ILT challenge virus to other broilers. This study reinforces the observation that biosecurity is very important to control spread of ILT from vaccinated flocks.
