vvlBD: Disease control and monitoring

摘要

IBD field challenges are dynamic. Certainly the management practices, environment, breed/hf bird and disease pressure are different and can change from region-to-region, farm-to-farm and flock-to-flock. When an IBD challenge becomes more robust, mildor intermediate IBD vaccines may no longer protect the birds; to maintain performance in those situations, an intermediate-plus vaccine (such as Bursine~R Plus, Bursaplex or Poulvac~R Bursa F), is an excellent option.
