In the poultry building, several exhibitors were turned away with their birds after state Agriculture Department officials said the birds did not have the
required LT-IVAS vaccination against infectious laryngotracheitis, a viral infection causing problems in birds’ respiratory tracts.
“We have to protect all the birds here,” said Deputy Agriculture Secretary Matthew Meals. “All chickens for exhibit must be from flocks vaccinated against this infection.
The vaccine we required is the only acceptable one.”
===========================
" LT-IVAS " vaccine
Infectious Laryngotracheitis Watery, inflamed, swollen eyes, swollen sinuses & wattles, nasal discharge, drop in egg production, coughing (sometimes with a bloody mucus), breathing through mouth with neck extended during inhale and head on breast with exhale, choking, rattling, drop in egg production or soft-shelled eggs. Spreads through flock in 2 to 6 weeks. Birds die or recover within 2 weeks of becoming sick. No effective treatment. Vaccinate to keep disease from spreading.
Survivors are immune, but survivors and vaccinated birds are carriers. This is a reportable disease in most states. Once a vaccination program is started, follow-up vaccination is necessary.

ILT can be effectively controlled by vaccination.
Vaccinated and unvaccinated birds should not be mixed due to the possibility of reversion to virulence.

Control focuses on management practices, emphasising strict biosecurity. Due to vaccination potential to cause disease, veterinary supervision is strongly recommended when the decision is made to go this route.
Since both natural infection and vaccination have been shown to produce "carrier" birds, it is extremely important that susceptible chicken flocks are not exposed to vaccinated or previously infected chickens. Mixing of birds should only be done when a complete history of the birds is available, and it is absolutely certain that a potential ILT "carrier" is not present. Sanitation procedures, which include disinfection of equipment, boots and clothing and proper disposal of litter and carcasses, are essential components of ILT control.
