“DEALING” WITH $ 4 CORN and $10 BEANS !
The following is a completeupdated listing of cheap, easily managed alternativesfor corn for your livestock rations….

EVERYBODY IS TALKIN ABOUT CORN!! FROM • “ There won’t be any corn left to feed livestock”!! TO “ Half these new ethanol plants will be broke within 5 years” !!
Economics are changing FAST!! YearDDGCorn Jan 2006 $122 /T $2.30 Jan 2007 $146/T $4.20 Oct 2007 $150- $ 4.00 $200
Feedstuff • November 5, 2007 • “Tight Ethanol Margins Expected to Continue” • “Industry in “cooling off” period” • “Construction/expansion pullbacks” • “More ethanol supply then blender capacity”
“35 billion gallons of alternative fuels in the next 10 years..”
Now this is high tech !!! ( Probably got bottled !! )

CONCERNS Nutrient Composition
Remember, when corn is fermented the starch is used and other nutrients are CONCENTRATED • Crude Protein- a good thing at proper levels • Fat -ruminants tolerate a total of about 7% • Phosphorus – Can lead to urinary calculi in males and land application problems in manure (nutrient management plans)

CONCERNS Variability !
DDGS varies in nutrient content and digestibility, color, and particle size among US sources

DDGS Variability-Possible Solutions • Minimize excessive drying/heating • Dryer temperatures range from 260° F to 1100° F • Reduces amino acid digestibility • Develop and implement standardized production procedures for all plants within the company
DDGS Variablity-Possible Solutions • Use defined quality criteria for screening corn • Minimize the number of corn varieties used • Blend a consistent amount of solubles with grains
CONCERNS Handling Characteristics
Flowability of DDGS • Some sources of DDGS do not consistently flow through transport and feed handling systems • Problems worse in summer • Problem worse with higher moisture DDGS
General Management: Wet Distillers • Within 100 miles of source • 1-2 week life “unprotected” • Bag it • Add preservatives • Ensile with other feeds
CONCERNS Anti-Quality Factors
Problems with DDGS • Mycotoxins • Main concerns • Aflatoxins-carcinogenic, regulated by FDA • Vomitoxin (DON)-feed refusal • Fumonisin-carcinogenic • Zearalenone-reproductive problems
Problems with DDGS • Mycotoxins • If contaminated corn is used, mycotoxins are concentrated 3X in DDGS • ELISA tests for mycotoxins may give false positive results • Use HPLC for accurate quantification
Problems with DDGS • Sulfur Content • Sulfur levels • Range from 0.31-1.93% • Variation partially due to use of sulfuric acid to clean fermenters
Problems with DDGS • Sulfur Content • Sulfur levels • High levels of sulfur in DDGS with high dietary inclusion rate, high S forages/water • polioencephalmalacia in cattle • Affect on feed intake and palatability of DDGS at high levels
Distillers Grains Value • A specific least-cost formulation for a specific feeding situation always best • Shortcut based on ground corn grain and soybean meal: • Breakeven price of DDGS ($/ton) =(corn ($/bu) x 17.85) + • (SBM ($/ton) x 0.5)
Distillers Grains Value (Oct 31 Chicago) Example: Corn grain- $3.62/bu SBM (48)- $271/T (3.62 x 17.85) + (271 x 0.5)= 200.12 - Breakeven 133/T - Market
Wet Distiller’s Value? Start with DDG value and discount for: a. Dry Matter- Ex: wet= 35% dry=88 35/88=0.398 b. Nutrient Comp. - Avg 98% of dry value c. Shrink - Avg 0.85 d. Storage costs - Avg $5/T Source-Distillers Grains 2007 OSU
Wet Distillers (200.12 x 0.398 x 0.98 x 0.85) - $5= $61.35/ ton delivered
“Livestock producers shouldn’t expect cheap distillers as potential increases may occur to keep ethanol producers in the black” (as corn prices and ethanol prices ).
