Why does coarse spray vaccination is practiced in broiler production?
To avoid severe vaccinal reactions coarse spray, intended to target the upper respiratory tract, is therefore used for primary vaccinations, while fine aerosol vaccination, intended to reach the lower respiratory tract, is performed as a booster. …
