Vetech Laboratories Inc. was
founded in
1983 in Rockwood, Ontario, Canada for the production of live coccidiosis vaccines for turkeys,
egg layers, breeders and broilers under
the trade name of IMMUCOX®.
Since then, Vetech has relocated its headquarters to Guelph,
Ontario,
Canada, with a U.S. distribution®center in Buffalo, New York.
We serve
the poultry industry, both nationally and globally,
and have pioneered a unique gel delivery system for our vaccines (Can.
Patent, patent pending in other countries). IMMUCOX®
vaccines are now distributed in over 40 countries worldwide.
Our
Contribution to Coccidiosis Vaccines and Vaccination...
"Uniform exposure" first proposed by Dr. Eng-Hong
Lee (Lee, 1986)* and recognised for its potential later by Shirley and
Long (1990)* has now been generally accepted as the basis for
successful
delivery of live coccidiosis vaccines to commercial poultry for the
last two
decades. Whether they are methods devised by others such as spray on
feed,
spray in eyes, water spray, our water diluent, our gel puck delivery
or now
the gel-spray delivery, they are one and the same, all aiming at
achieving
uniform exposure.

Poultry
Puck as Hydration Product...
Our "Poultry
Puck" is now recognised as one of the best hydration products to hold
or ship hatchlings around the world because of two unique features:
- Although
it holds over 95 % of water, it will not wet the hatchlings
- It
is commercially sterile before placement
New
Direction for Coccidiosis Control...
We
feel that combination of vaccination and
medication in the same crop (Lee, 2001)* is
an option
whose time has come. One that can be used to eliminate both the
continuous
problem of drug resistance and reducing the nagging problem of necrotic
enteritis
associated with coccidiosis vaccination. Vaccinated hatchlings were
first fed
with non-anticoccidial starter then around 15 days of age, at least one
load of
grower feed medicated with an existing anticoccidial is used to
mitigate
possible vaccine reactions before continuing with feeds with growth
promotants
only until market (Table 1). By curbing vaccine reaction, necrotic
enteritis
will be seriously curtailed as well. This
combination program should also be applicable to the control of
coccidiosis in breeders,
egg layers and turkeys. This option for the control of coccidiosis in
commercial poultry should have its uses extended far into the future.
