Ration Formulation Handout 1. Formulate a 500 lb. cattle feed ration that requires a CP of 23%. Your feeds are corn at 9% CP and a supplement at 15%. Show ALL your work below. Corn – 9% 8 parts corn 23 Supp. –15% 14 parts Supp. 22 total parts 8 parts corn / 22 total parts = .363636 x 100 = 37% corn 14 parts supp. / 22 totally parts = .636363 x 100 = 63% supplement .37 corn x 500 = 185 lbs. of corn .63 supp. x 500 = 315 lbs. of supp. 2. You have a goat that is on a feed that requires a CP of 30%. The CP of the two feeds you are going to use are barley at 7.2% CP and soybean meal at 18% CP. Using these two feeds, formulate a 150 lb. ration that meets the requirements of your goat. Show ALL work below. Barley – 7.2% 12 parts barley 30 SBM – 18% 22.8 parts SBM 34.8 total parts 12 parts barley / 34.8 total parts = .3448 x 100 = 35% barley 22.8 parts SBM / 34.8 total parts = .6551 x 100 = 65% SBM .35 barley x 150 lbs. feed = 52.5 lbs. barley .65 SBM x 150 lbs. feed = 97.5 lbs. SBM 3. You are the owner of a feedlot trying to finish out some cattle for slaughter. You need 5000 lbs. of feed that have a CP of 55% at the lowest cost possible. You have several feed options to choose from. Utilizing these feeds, create a ration that meets the nutritional requirements of your cattle at the most efficient cost to you. Show ALL work, including the final cost of your feed!! Corn- 8% CP, $ .76 per lb. Barley – 7.8% CP, $. 62 per lb. Wheat Straw – 13% CP, $1.02 per lb. Soybean Meal – 44% CP, $2.50 per lb. Molasses – 5% CP, $ .50 per lb. Fish Meal – 50% CP, $1.00 per lb. Barley – 7.8% 50 parts Barley 55 Molasses – 5% 42.2 parts Molasses 92.2 total parts 50 parts Barley / 92.2 total parts = .5422 x 100 = 54% barley 42.2 parts Molasses / 92.2 total parts = .4577 x 100 = 46% molasses .54 barley x 5000 lbs. = 2700 lbs. barley x $0.62 = $1674 .46 molasses x 5000 lbs. = 2300 lbs. molasses x $0.50 = $1150 = $2824 total cost
