in feed. Any type of stress in farm.

No treatment. Vaccinate birds , repeat vaccine only if

previous vaccine was done 15-20 days before. Surviving birds are susceptible to E. coli,

respiratory infections, coccidiosis, IBD and ND so precautionary measures should be taken.

To avoid secondary infections specially respiratory infections use broad spectrum antibiotics after vaccination.
