Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

Animal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.
