Technical Abstract: During a natural outbreak of infectous laryngotracheitis (ILT) that occurred in Mississippi in late 2002 and extended into early 2003 the method of administration (water or spray) and dosing (full or half) regimens for ILT vaccination were investigated. The study involved three poultry companies, encompassed 27 broiler farms and comprised a total of 965 chickens. Results of the study showed that the majority of chickens sero-converted by three weeks post-inoculation regardless of vaccine administration method and post-inoculation mortality was not different among treatments
