Missouri does not have a beef expo. The Mizzou AGR is usually in early Feb, but has been moved to March 14-15 for 2015. It is also usually in Columbia, but has also been moved to the state fairgrounds in Sedalia. There is usually a show every weekend from March-April. Either check out the MO Cattleman's Page or look-up the Missouri Club Calf Association. Both have a points system and sanction several shows.
