摘要

Influenza A viruses in swine (IAV-S) circulate widely in the United States annually, peaking in the late fall through the early spring. Although most breeding swine with IAV will recover without performance consequences, IAV can cause severe disease and in some cases death, particularly in immunocompromised and/or co-infected animals. Increased abortions, decreased conception rate and increased sow mortality are common sequelae to a novel IAV-S introduction. It can be difficult to started weaned pigs on sow farms that are IAV-S positive. In one study, the cost per head due to losses such as mortality, culls and tail-enders was $3.23.'
