In preparation, exhibitors need to know the importance of a Certificate of Veterinary Inspection (CVI), more commonly known as a health certificate. Any time an animal moves into another state, a CVI is required. When it comes to livestock shows, many will require a CVI even if the animal doesn’t have to cross state lines to get to the show. All CVIs have two basic requirements: a visual inspection of the animal must be performed and the animal must have identification. The visual inspection of the animal must be done by an accredited veterinarian within 10 days of the expected date of travel.
