Wes and his family own a small farm on which he has four pleasure horses and 45 ewes. They applied 40-60-35 units of fertilizer per acre to 60 acres of pasture using 46-0-0 urea at $512 per ton, 18-46-0 DAP at $708 per ton, and 0-0-60 muriate of potash at $685 per ton. They reseeded the pasture with 8pounds per acre of orchard grass at $1.40 per pound and 2.5 pounds per acre of clover at $2 per pound. The ewes average 1.75 lambs per ewe with an average weight of 10.8 pounds. They sold the lambs at 6 months of age averaging 120 pounds. The ewes produce 11 pounds of wool per ewe per year. The ewes are fed a balanced ration of 18 percent CP with 70 percent TDN using alfalfa-grass hay with15.8 percent CP and 48.2 percent TDN, corn with 8.6 percent CP and 78.1 percent TDN, and soybean meal
with 46.8 percent CP and 75.2 percent TDN. a. What did it cost to fertilize and reseed the pasture? b. What was the average daily gain of the lambs in ounces? (Note: 1 mo = 30 days.) c. How many pounds of each feedstuff were needed to make a ton of the feed ration?
