"

Timing of water withdrawal is also important. Water not withheld long enough means
birds won't be thirsty enough to drink, but if water is withheld too long, the thirstiest
and dominant birds will consume the lion's share and some birds won't get the vaccine
at all. If it takes birds less than 1 hour to consume the vaccine, the water was probably
withheld too long.

Q: What's the consumption time for live IBDV and reovirus vaccines in water?
KC: About 90 minutes. That may seem like a long time, but IBDV and reovirus are hardy,
and titers won't drop like they will with respiratory vaccines. Allowing 90 minutes for
consumption helps ensure uniform coverage.

Q: How long will broiler progeny be protected from IBDV and reovirus after live priming
of breeder pullets?
KC: The more uniform and higher your IBDV and reovirus titers are in breeder pullets, the
longer progeny will be protected. You want passive IBDV immunity for at least 14 and
preferably 18 days. With reovirus, you want passive immunity until at least 10 days of age.
Don't be surprised if IBDV titers persist longer than reovirus titers.
Q: What else can be done to improve live IBDV and reovirus priming?
KC: Walk the house when vaccinating, especially along the side walls. If you see birds that
aren't going to water, get them moving to encourage them to drink.
Q: What about using a recombinant herpesvirus of turkey IBDV vaccine for priming?
KC: The recombinants do a good job protecting pullets but are no substitute for live
priming. I say that based on experience with a large poultry company that used a
recombinant without also using live priming, and the results were mixed. By the second or
third growout, flocks in areas with a lower field challenge had IBDV titers at 10 weeks of age
that were far lower compared to what they were with conventional priming. And the IBDV
titer response after the inactivated vaccines was lower and less uniform.

SAFETY INFORMATION

· In case of accidental human injection
seek immediate medical attention.
· Do not vaccinate within 42 days
before slaughter.

SPECIAL ADVERTISING SUPPLEMENT

Q: Do you have any tips for improving administration of the Zoetis inactivated IBDV
and reovirus vaccine, Poulvac Maternavac®?
KC: Here again, proper administration is key. If the vaccination crew works too fast,
they might vaccinate inaccurately or pull the needle out prematurely and end up giving
a partial dose. Crews certainly need to work efficiently but not so fast that it jeopardizes
proper administration.
