Problems: Follow the directions line-by-line and you should be fine. 1. Start with cottonseed hulls as the diet at 100%. Substitute corn for cottonseed hulls to get the gain to 2 lb/day. Adjust the protein to 97 to 103% of the requirement by substituting soybean meal 49 for corn. Correct the phosphorus deficiency using dicalcium phosphate substituted for the cottonseed hulls. This will cause the least amount of gain decline. Correct the calcium deficiency by substituting limestone for cottonseed hulls. Make minor adjustments as needed to get individual values within the acceptable ranges. Enter your numbers in the appropriate column on the "Stocker 2" worksheet on the AN21Stocker Problems-Template spreadsheet. 2. Start with com and cottonseed hulls in a proportion to get 2 lb/day. Take out 1% cottonseed hulls and add 1% urea in the diet. Correct the rest of the protein deficiency by substituting soytlean meal for corn. Correct the phosphorus deficiency using dicalcium phosphate substituted for the cottonseed hulls. Correct the calcium deficiency using limestone substituted for cottonseed hulls. Make minor adjustments as needed to get individual values within the acceptable ranges. Enter your numbers in the appropriate column on the AN21Stocker Problems-template spreadsheet 3. Start with com and cottonseed hulls in a proportion to get 2 lb/day. Take out 1% cottonseed hulls and add 1% urea in the diet. Correct the rest of the protein deficiency by substituting blood meal for cottonseed hulls. This may result in the gain being above the range, so readjust the amounts of corn and cottonseed hulls to get the gain back within the acceptable range. Correct the phosphorus deficiency using dicalcium phosphate substituted for the cottonseed hulls. Correct the calcium deficiency using limestone substituted for cottonseed hulls. Make minor adjustments as needed to get individual values within the acceptable ranges. Enter your numbers in the appropriate column on the AN21Stocker Problems-template spreadsheet 4. Start with distillers dried grains and cottonseed hulls in a proportion to get 2 lb/day. Correct the calcium:pbosphorus ratio using limestone substituted for cottonseed hulls. Make minor adjustments as needed to get individual values within the acceptable ranges. Your CP and P will be in excess, so don't worry about that. Enter your numbers in the appropriate column on the AN21Stocker Problems-template spreadsheet The following information is the same as we used for the first stocker cattle problen set. Check it to make sure. Number of Head 400 Sex steers Start date: 1/15/2021 Calf age (months) 8 Start weight (lbs) 300 Start Body Condition 4 (moderately thin) Calf Breed Type English x Continental (growth) (#7) Estimated mature weight (lbs) 1350 Estimated feeding days 229 Desired rate of gain 2.00 Target ending weight 758 Growth Implant (y) lonophore Fed (y) n Use the following specifications unless told not to do so. gain within +0.10 b/day Protein between 97 and 103% of the requirement. Phosphorus and calcium between 100 and 103% of the requirement Ca:Pratio is between 1.5 and 2.0 and Ca and P must be at least at 100% of their individual requirement. (There are times where the actual concentrations of Ca and P are excessive. This is fine IF the excess is coming from natural feedstuffs and not a specific Ca or P source.)
