Iowa state vet discusses HPAI identification

A state veterinarian says poultry producers can identify highly pathogenic avian influenza in several ways.

Dr. Jeff Kaisand from Iowa says some egg layers may show signs of depression when infected. “One of the things we see a lot with in chickens is their head drooped over,” he said. “But one of the things often seen is just sudden mortality with no other clinical signs.”

He tells Brownfield when some birds have trouble moving oxygen, “Their combs and wattles may become cyanotic, blue because they are not circulating a lot of oxygen. They can also have diarrhea. Anything in those categories is something that can go along with avian influenza.”

Kaisand says thousands of infected birds have been depopulated in the state this fall, but farm to farm spread has been minimal.
