New in ovo machine
available for smaller
The ;rst commercial in ovo vaccination
system was launched by Embrex, now a
part of P;zer Animal
Health Global Poultry,
in 1992. In the
ensuing two decades,
in ovo vaccination
has become standard
practice for the U.S.
and Brazilian broiler
industries. Today, in
ovo vaccination is
used on more than
90% and 70% of U.S.
and Brazilian broilers, respectively. It is
estimated that more than 15 billion eggs per
year are processed with inovo equipment, but
most of this occurs in large hatcheries.

Inovo vaccination will now be available
to more hatcheries worldwide, with the
development of a new compact device.
Embrex Inovoject m is an inovovaccination
system designed for those poultry hatcheries
that do not have a large enough footprint
or throughput to justify the installation
of a full-size Inovoject. The new device
allows these hatcheries to benefit from
the improved accuracy, reliability and
ef;ciency of in ovo vaccination, but in a
more compact form.
Inovoject m is a semi-automatic device
that allows trays to be both introduced and
removed by an operator; an added transfer
head/table can be provided at an additional
charge. A working capacity of between
12,000 and 20,000 eggs per hour can make
inovo vaccination an alternative for smaller
In ovo vaccination provides a number
of advantages over both day-of-hatch and
on-farm vaccination. Immunity against
disease is generated as early as possible
and with minimal interference from
maternally derived antibodies. The vaccine
is delivered reliably and accurately in
carefully controlled, hygienic conditions.
The process is less labor intensive and less
prone to human error, and chick handling
is minimized, reducing bird stress and
improving bird health.
