With the CPJ Vaccinator, one person can vaccinate
roughly 75,000 chickens in about 7 minutes, compared to five people taking 45
minutes to get the job done conventionally. Click the image for more

Better, Faster Vaccinations for Poultry
December 20, 2005
Egg producers now have access to a
new tool developed by the Agricultural Research Service (ARS) that helps protect laying flocks from
serious diseases like infectious bronchitis, mycoplasmosis and exotic Newcastle
disease. Each year, mycoplasmosis alone costs U.S. producers more than $140
million, partly due to uneven vaccine delivery.
Vaccines are currently dispensed to egg-laying leghorn chickens as an
inhalable mist sprayed inside poultry houses. The applicator consists of a hose
attached to a machine inside a backpack that resembles a modified leaf blower.
The machine makes an ear-piercing noise that disturbs the birds, while the
vaccine spray reaches its intended targets only about half the time.
Now, a more effective vaccinator has been developed by ARS researchers in
Research Unit at Mississippi State, Miss., under the leadership of
supervisory veterinary medical officer
Branton. Named for
Johnson, the CPJ Vaccinator is a battery-powered, 6-foot-tall by
5-foot-long device with nozzles on both sides that quietly spread the vaccine
to three tiers of birds at once without disturbing them. The vaccine is
dispensed so uniformly that it reaches more than 90 percent of the birds to be
treated. Branton modified the device to meet industry standards.
Field trials at the Cal-Maine Foods,
Inc., egg-production facility in Edwards, Miss., showed the CPJ Vaccinator
to be efficient, effective and easy to use. With it, one person was able to
vaccinate roughly 75,000 chickens in about seven minutes, compared to five
people taking 45 minutes to get the job done conventionally.
A manufacturer for the CPJ Vaccinator has been found, and the device is now
commercially available through the Long Branch Company, Inc. of West Point,
ARS is the U.S. Department of
Agriculture's chief scientific research agency.
