CONTROL

  • Vaccination: Inactivated vaccines with oil adjuvant are available. They reduce but do not prevent virus shedding. These vaccines are given during the growing phase, usually at 14-18 wk old, and can be combined with other vaccines such as for Newcastle disease.
  • Eradication: The endemic form can be controlled by washing and disinfecting plastic Keyes trays before reuse. The sporadic form can be prevented by separating chickens from other birds, especially waterfowl. General sanitary precautions are indicated, and potentially contaminated water should be chlorinated before use.
