spray vaccination
One of the key process
changes required to facilitate
faster growing broilers is moving
a wide variety of diseasepreventing
vaccinations
backwards from the broiler
house to the hatchery. Live respiratory
(viral), coccidial and
salmonella vaccines may all be
administered by spray in the
hatchery in cabinets specially
designed to inoculate large
numbers of birds efficiently
and effectively. Hatchery spray
cabinets can also deliver probiotic
cultures and competitive
exclusion products that seed
the gut with beneficial bacteria
before pathogenic bacteria
can take hold.
Spray vaccination seems
easy in theory, but extreme
care must be taken in setting
up and running the process to
ensure proper vaccination. The
spray pattern is particularly important
as the routes of vaccine
uptake include the eyes, the
nares and preening vaccine
droplets from the down, so
coverage of the entire vaccination
box is essential.
