Operators of central bull test stations often determine sale eligibility using a selection index, whereas coordinators of the Wardensville Bull Test use independent culling levels derived according to deviation from contemporary group mean. Data from the 2013–2015 Wardensville Bull Test program were used for determining mean numbers of bulls culled for six eligibility criteria for three variation-based culling levels. Then comparison of these methods was used for determining the most appropriate method relative to program goals and producer needs. Suggested sale eligibility criteria are provided. Extension professionals can educate relevant audiences regarding the value and correct application of the variation-based method.
