Influenza in commercial broiler breeders
1992
Halvorson, D.A. | JSivanandan, V. | Lauer, D.
Influenza was detected in a flock of broiler breeders during routine serological monitoring. Although there were no clinical signs, egg production may, have been affected in hens on one story of a two-story breeder house. Intensive measures were taken to avoid transmission to other farms. Two months after the flock was found to be serologically positive, sentinel hens were placed in the flock, and they became serologically positive 1 month later. In spite of this evidence for virus being present in the flock, no detectable transmission to any other farm occurred.
