Economic Analysis Of Stockers Grazing Botanically Diverse Summer Annual Pasture, Kelly M. Mercier, Christopher D. Teutsch, S. Ray Smith, Kenneth H. Burdine, Eric S. Vanzant, Edwin L. Ritchey

Journal of Extension

Economic analyses were performed to determine the feasibility of retaining weaned fall-born calves on summer annual pastures (a monoculture, a 3-species mixture, or a 12-species mixture). Average daily gain was reduced by 0.3 lbs/day in calves grazing the complex mixture in two out of three years. Enterprise budgeting illustrated that retaining calves on summer annual forages was not economical. Two-way net return tables indicated that this scenario would only be profitable when cattle prices are high and pasture establishment costs are low. Extension educators should be sure to emphasize the economic risks when discussing these systems.
