A rancher in eastern Oregon has a year-long BLM grazing allotment in the Palouse Prairie that is 50,000 acres in size. Seventy percent of this allotment has loam soils and produces 1,000 lbs. of forage per year (dry matter; DM) and the remaining 30% has sandy loam soil and produces 650 lbs. of forage per year (DM). The allotment is split into large pastures enabling rotational grazing to take place and allowing the producer to practice the "take half, leave half" philosophy of grazing (i.e., utilization rate = 50%). As part of his agreement with BLM, the rancher must account for 50 head of feral horses (1,000 lbs.) and 40 head of pronghorn antelope (110 lbs). With the remaining forage, determine how many mature 1000 lb. cow/calf pairs (1 cow/calf pair - 1 AUM) the rancher could run on this allotment.
