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
