2 How Much DDGS can the US Livestock Industry Use? 17.58 billion lbs Swine 6.02 billion lbs Broilers and Turkeys 97.14 billion lbs Grand Total 73.54 billion lbs Cattle Total 18.20 billion lbs Heifers and calves 16.75 billion lbs Dairy Cows 20.34 billion lbs Beef Cows 18.25 billion lbs Slaughter Cattle ** Estimated 66.7 billion lbs produced by the end of 2007 ** 100% of the livestock category using DDGS at current recommended levels Indiana Proposed Ethanol Plants Dry grind – possible fractionation Estimated 1.4-1.9M tons DDGS Typical inclusion rates Swine 10% Poultry 5% USDA Ag Statistics, 2006 Maximum IN utilization: 1.33M tons (70- 90.5%) Realistic utilization in Indiana: 30-50% SBM vs DDGS DDGS contains 57% of the protein of SBM (27.3/47.5) DDGS contains 28% of the total lysine of SBM (.84/3.02) DDGS contains 20% of the available lysine (.52/2.57) This is why it replaces a greater percentage of Corn in the diet than SBM in monogastric diets SBM vs DDGS Swine Example – 10% DDGS in WF Pig consumes about 110 lb of SBM and 565 lb Corn from weaning to market DDGS could replace about 2.42 lb SBM / Pig DDGS could replace about 36.7 lb Corn / Pig In Indiana = 4.2 million bushels of corn In Indiana = 7,744 ton SBM Wet system - frequent delivery of wet DGs Flat storage Cost of transporting water 3 - 7 day shelf-life Ensiling (corn stover, silage, soyhulls, straw) DDGS Bridging in bins and rail cars (BN, UP) Separation Particle size 400 microns Pellets (limited to 5 - 7% inclusion rate)
