How many days can pigeons compete with Newcastle disease?

Pigeons with Newcastle disease can compete for 5 days or 14 days. Because it depends on what vaccine you get.

1. If the water-soluble vaccine for nose and eyes is used, pigeons can take part in the competition after 5 days of recovery.

2. It will be even worse if you use the oil emulsion Xincheng vaccine injected subcutaneously. Pigeons need two weeks to recover.
