Livestock exhibitors at the 2026 Missouri State Fair must submit DNA samples collected as hair follicles for market animals. Nose prints and blood samples are no longer accepted. Deadlines for submitting DNA samples vary by species. Exhibitors must pull hair with root follicles attached and follow specific guidelines for collection and submission. Entries without proper animal ID will not be accepted, and samples must be certified by an agriculture teacher or extension agent before submission to the Missouri State Fair. For more information, visit the Missouri State Fair website or contact the Competitive Entry Supervisor.
