If you suspect a problem, send a DDGS sample to an analyticallab for a mycotoxin analysis.Or you can purchase DDGS only from ethanol plants thatdo not buy damaged grains. Visit with each plant managerto learn the plant’s policy on purchasing mycotoxin-contaminatedgrains. While damaged corn will not have muchnegative impact on ethanol production, it could have agreat impact on the mycotoxin levels in the DDGS. Also,even in the best quality-control systems, some damagedcorn can get in.Therefore, it is strongly recommended to start conservativelywhen including DDGS in gestation and lactationdiets.Incorporating DDGS into swine dietsPigs require amino acids, not protein, so swine diets needto be balanced on a lysine or digestible lysine basis, not oncrude protein. While DDGS is relatively high in protein, itis still low in lysine, the first limiting amino acid for swinein grain-based diets.Due to its poor amino acid balance for pigs, corn is a poorquality protein source for pigs. When corn is processedinto DDGS, the poor amino acid balance is concentrated,not improved in DDGS. Therefore, to properly incorporateDDGS in swine diets, the diets must be formulated ona lysine or digestible lysine basis. If the diets are balancedon crude protein, the diets will be grossly deficient inlysine and other essential amino acids, and pig performancewill be substantially decreased.Keep in mind that DDGS is not just another amino acidsource. It is also an excellent source of digestible phosphorus.Therefore, when adding DDGS to a diet, you willbe able to reduce the amount of dicalcium phosphate normallyused.As was mentioned before, source of DDGS is critical onpig performance. The recommendations in Table 3 arebased on a high quality DDGS and on diets balanced ondigestible lysine and phosphorus.It is recommended to start at the lower inclusion level andthen gradually work your way up to the maximum inclusionrate, especially for sows. University of Minnesota hasshown that going immediately to the higher levels forsows resulted in an initial reduction in feed intake forabout 1 week before they went back to full feed. Also,3Table 3. Recommended inclusion rates of DDGS in swinediets.Starting MaximumPhase point inclusion rateNursery (>15 lbs) 5% 25%Grow-finish 10% 20%Gestating sows 20% 50%Lactating sows 5% 20%Boars 20% 50%mycotoxins have the greatest effects on reproduction, soextra care must be taken when using DDGS in sow diets.DDGS concentrations up to 30% of the diet have no effecton grow-finish pig performance. However, the 30% inclusionlevel does result in carcasses that have reduced bellyfirmness and more soft fat due to the high concentrationsof polyunsaturated fatty acids in DDGS. Therefore, 20%is the maximum recommended amount in grow-finishdiets.StorageDDGS contains approximately 10% fat, and a large portionof that fat is composed of polyunsaturated fatty acids.Since polyunsaturated fatty acids are subject to rancidity,you will need to use DDGS as quickly as possible. It isrecommended that you buy no more than a 3-month supplyof DDGS in the winter and no more than a 1-monthsupply in the summer.Due to its high fat content, DDGS “flowability” throughbulk bins may be a potential problem. Use caution whenselecting the facility to store DDGS in on-farm.Health benefitsThere have been reports by producers that 10-20% DDGSin grow-finish diets reduces the incidence/severity of ileitisand Hemorrhagic Bowel Syndrome (HBS). However, nocontrolled research trials have been conducted to demonstratethis effect. SDSU and the University of Minnesotaare currently conducting such trials, but we have no data tooffer at this point.Therefore, use caution in applying any economic value toDDGS’s health effects until the trials are completed.
EconomicsDDGS provides lysine, phosphorus, and energy, and itreplaces soybean meal, dicalcium phosphate, and corn.When considering the economics of using DDGS, all thesefactors must be included.As a “rule of thumb”, 200 lb of DDGS and 3 lb of limestonecan replace 178 lb of corn, 19 lb of 46% protein soybeanmeal, and 6 lb of dicalcium phosphate in a ton ofcomplete feed. However, by balancing on a digestibleamino acid basis and making certain all ten essential aminoacid requirements are being met, higher concentrations ofDDGS can be used in swine diets.Table 4. Determine the approximate worth of DDGS inyour swine diets.Ingredients $/lb Lb Total costDDGS _____ _____ _____Limestone _____ _____ _____Corn _____ _____ _____SBM (46% CP) _____ _____ _____Dical Phos (18.5% P) _____ _____ _____Total cost, $ _____ _____ _____If DDGS is $85/ton ($.043/lb), 46% SBM is $245/ton($.123/lb), corn is $2.37/bu ($.042), limestone is $.013/lb,and dical phos is $.15/lb, you can calculate the worth of200 lb of DDGS.Table 5. The worth of 200 lb of DDGS.CurrentIngredients $/lb Lb DDGS cost costDDGS .043 200 8.60Limestone .013 3 .04Corn .042 178 7.48SBM (46% CP) .123 19 2.34Dical Phos (18.5% P) .15 6 .90Total cost, $ $8.64 $10.724In this example, a 10% inclusion of DDGS (200 lb/ton)would save $2.08/ton of feed. Assuming that it takes threepigs to consume one ton of feed, using 10% DDGS wouldreduce diet cost by $.69/pig in this example.For ease of calculation, there is an Excel spreadsheet availableat your local county Educator’s office and also on theAnimal and Range Sciences Department homepage(http://ars.sdstate.edu/).If you properly formulate diets so that the DDGS concentrationsdo not exceed the maximum recommended levels,the decision to use DDGS depends on which complete dietis less expensive—corn-SBM or corn-SBM-DDGS.SummaryDDGS is a co-product from the ethanol industry and is asource of amino acids and phosphorus for swine.Producers must be aware of the wide range of nutrientsand potential mycotoxin problems associated with DDGS.However, a proper analysis or screening program can alleviatethose concerns.DDGS can work well in swine rations at the proper inclusionlevel when the diets are balanced on digestible aminoacids and phosphorus. Once that is done, the decision touse DDGS or not depends on economics.For further information on DDGS, please contact yourlocal county educator or Bob Thaler at 688-5011(Robert_thaler@sdstate.edu).This publication and others can be accessed electronicallyfrom the SDSU College of Agriculture & BiologicalSciences publications page athttp://agbiopubs.sdstate.edu/articles/ExEx2035.pdfor the Extension Service Drought Information Website athttp://sdces.sdstate.edu/drought/Issued in furtherance of Cooperative Extension work, Acts of May 8 and June 30, 1914, in cooperation with the USDA.
