compared to chicks fed the lightest-colored DDGS. Results from this study suggest that DDGSthat is dark in colored and/or has a burnt smell should not be used in swine or poultry diets.Source: Cromwell, G.L., K.L. Herkleman, and T.S. Stahly. 1993. Physical, chemical, and nutritionalcharacteristics of distiller’s dried grains with solubles for chicks and pigs. J. Anim. Sci. 71:679-686.In order to differentiate DDGS sources that are suitable for swine and poultry diets from othernutritionally inferior sources, the Minnesota and South Dakota ethanol plants have establishednutrient specifications and recommended physical characteristics when selecting DDGS sourcesfor swine and poultry diets.Minnesota-South Dakota Nutrient Specifications and Physical Characteristics forDDGS in Swine and Poultry DietsNutrient specificationsMoisture – maximum 12%Crude protein – minimum 26.5%Crude fat – minimum 10%Crude fiber – maximum 7.5%Physical characteristicsPork fat qualityBulk density – 34 to 37 lb/cubic footParticle size:maximum coarse particles - 10% on 2000 screenmaximum fine particles - 15% on 600 screen & in panSmell – fresh, fermentedColor – goldenrodOur studies have shown that when feeding DDGS to grow-finish pigs (50-250 lbs), the oilpresent in DDGS will make pork carcass fat softer and more oily with increasing levels of DDGSin the diet. Similar effects have been shown when adding any high oil grain or grain co-productto swine grow-finish diets. Although softer fat and reduced belly firmness are a concern forpackers and meat processors, there currently are no price penalties for pork producers formarketing pigs with reduced pork fat quality. Results from our studies show that feeding up to20% DDGS in grow-finish diets has no effect on belly thickness or belly firmness scorecompared to carcasses from grow-finish pigs fed conventional corn-soybean meal diets.MycotoxinsThe incidence of documented cases of mycotoxicosis from feeding DDGS to swine is extremelylow. However, corn is susceptible to molds that can produce mycotoxins prior to harvest, as wellas during storage. The primary mycotoxins of concern to swine are zearalenone, vomitoxin4
(deoxynivalenol), T-2 toxin, fumonisin, and aflatoxins. In the Midwestern U.S., zearalenone andvomitoxin are the greatest risks.If corn containing mycotoxins is delivered to an ethanol plant for ethanol production, thesemycotoxins are not destroyed or inactivated during the fermentation process and will be presentin DDGS produced from this corn source. In fact, the concentration of mycotoxins in DDGSwill be 2 to 3 times higher than the initial concentration in the grain because the removal ofstarch during the fermentation process concentrates all of the unfermentable residual portions ofthe grain that remain after fermentation.Ethanol plants are encouraged to monitor incoming corn for mycotoxins and reject loads that arecontaminated to prevent mycotoxins in DDGS. Buyers of DDGS are encouraged to work withtheir suppliers to establish a quality control protocol for the production of DDGS that shouldinclude screening tests and procedures for mycotoxins.Feed intakeOur studies have shown that feeding nursery and grow-finish pigs diets containing up to 25-30%DDGS from a high quality source has no detrimental effect on feed consumption. However,abruptly switching gestating sows that are being fed 4 to 5 lbs per day of corn-soybean mealbased diet to a diet containing 50% DDGS can cause sows to not consume all of the feed offeredfor a period of 5 to 7 days. After sows have adapted to the 50% DDGS diet, feed consumptionand weight gains are equivalent to sows fed a conventional corn-soybean meal diet. We haveobserved a similar response when feeding lactating sows a diet containing 20% DDGS.Although our preliminary results suggest no negative effects on reproductive performance fromthis slight reduction in feed intake during this diet adaptation period, it can be avoided by feedinglower levels of DDGS initially and then gradually increasing the inclusion rate of DDGS to ahigher, desired level for the duration of the production phase.5
