Learn how to calculate feed costs for livestock by assessing the cost per unit of nutrient supplied. Get insights on pricing feeds per ton and converting prices based on dry matter or as-fed weights. Explore examples with protein content calculations to optimize feed budgeting for efficient livestock nutrition.

Feed Costs • Cost per unit of nutrient supplied • Usually protein or energy • Most feeds are priced $ per ton • (If $ per bushel, need lb/bu) • Corn = 56 lb/bu • Barley = 48 lb/bu • Oats = 32 lb/bu
Feed Costs • Be sure to use DM/as-fed conversions depending on the feed composition values • Prices are always on as-fed weights
Feed Costs • Example: • 20% CP cubes (DM basis) • $170/ton, 90% DM
Feed Costs • Determine total lb of nutrient in a ton • 2,000 lb x 0.90 = 1,800 lb DM • 1,800 lb DM x 0.20 = 360 lb CP in ton • Determine cost per lb of nutrient • ($170/ton)/360 lb CP = $0.47/lb CP
Feed Costs • Example: • 18% CP alfalfa (DM basis) • $90/ton, 88% DM • 2,000 lb x 0.88 = 1,760 lb DM • 1,760 lb DM x 0.18 = 316.8 lb CP in ton • ($90/ton)/316.8 lb CP = $0.28/lb CP
Feed Costs • Example: • 30% CP liquid supplement (as-fed) • $200/ton • 2,000 lb x 0.30 = 600 lb CP in ton • ($200/ton)/600 lb CP = $0.33/lb CP
