All animals need to be healthy and suitable for a public exhibition.  The fair is our chance to display our agriculture industry to the public in a fun positive environment.  If you have any concerns regarding the health status of your animals, a visit by your veterinarian before the fair for vaccinations and a physical exam may be worthwhile to avoid the heartbreak of having to remove your animals at the fair check-in for health reasons.
