Turkeys between 12 to 16 weeks most susceptible to avian flu
Turkeys between the ages of 12 to 16 weeks seem to be the most susceptible to avian influenza. Minnesota Turkey Growers Association executive director Steve Olson says younger birds aren’t getting sick.
“Like-wise with broiler chickens which are raised to six weeks of age or so, have not been infected with (avian flu). So it may be a function of there’s something going on when those birds get to be older.”
USDA’s Animal and Plant Health Inspection Service this month announced new information about the virus in a follow-up report to a June study and warns producers to be extra vigilant about protecting birds in the 12 to 16 week age group. The typical lifecycle for commercial turkeys is anywhere from 12 to 22 weeks.
