PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME (PRRS) - ITS IMPACT ON PIG PERFORMANCE, PREVALENCE AND CONTROL

摘要

The effect of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) was first seen in the UK in 1991, This and other viral insults have depressed performance in growing and finishing pigs in infected herds. The use of diagnostics to determine if a herd is infected, and when pigs are challenged, provide useful information when formulating methods of control. Use of appropriate vaccines and the response to vaccination is supported by trials and case studies.
