A cow and calf (cattle <br />animal unit) consumes 900 pounds of air dry forage per month and a ewe and <br />lamb (sheep animal unit) consumes 150 pounds of air dry forage per month. <br />The conversion of oven dry weight to air dry weight is 1.11. The ideal <br />utilization factor for forage grazing is 50 percent. The livestock carrying <br />capacity was determined by the following: <br />LCC = (1.11 x FA x .5)/FC <br />Where: <br />LCC = Livestock Carrying Capacity (AUM per acre) <br />FA =Forage Available (oven dry lbs/acre) <br />FC =Forage Consumption Requirement <br />(900 lbs for cattle AUhi; <br />150 )bs for sheep AUM) <br /> <br />8 <br />Exhibit 10, Item 5 Revision Date: 03/06/07 <br />13 Revision No.: PR-02 <br />
