20% inclusion rate is used then synthetic lysine and tryptophan should be added to maintain anamino acid balanced diet with adequate growth performance.Recommended Maximum Inclusion Rates of DDGS in Swine DietsBased upon research studies conducted at the University of Minnesota over the last threeyears, the recommended maximum usage rate of DDGS in swine diets are as follows (Assumingthat high quality DDGS is free of mycotoxins):Production PhaseMaximum % of DietNursery pigs (> 15 lbs) 5Growing pigs (35-125 lbs) 10Finishing pigs (125-260 lbs) 20Developing Gilts 20Gestating sows 50Lactating sows 20Boars 50Table 1 gives a comparison of nutrient content, apparent amino acid digestibility, andphosphorus availability of MN/SD DDGS, a low quality DDGS source, and NRC (1998).Table 1.

Cautions in <strong>Feeding</strong> DDGS to Swine1. Qualitya. There is a large variation in the quality of DDGS available for swine feeds.Golden color DDGS is much better suited for swine diets than darker coloredDDGS due to higher amino acid digestibility.b. Odor ranges form sweet to smoky to burntc. According to research at the University of Minnesota, DDGS produced by newMidwestern plants is higher in nutrient content and digestibility (Table 1) thanDDGS from older plants.d. Quality considerations for selecting DDGS sources;Nutrient Specifications• Moisture – maximum 12%• Protein – minimum 26.5%• Fat – minimum 10%• Fiber – maximum 7.5%2. Nutrient variability of Midwestern DDGS sourcesa. Dry matter – 87 to 93%b. Crude protein 23 to 29%c. Crude fat 3 to 12%d. Ash – 3 to 6%e. Lysine – 0.59 to 0.89%3. Pork fat qualityUniversity of Minnesota studies have shown that when feeding DDGS to G-F pigs(50-250 lbs), the oil present in DDGS will make pork carcass fat softer and moreoily with increasing levels of DDGS in the diet. These same studies showed thatfeeding up to 20% DDGS in G-F pig diets had no effect on belly thickness orbelly firmness score compared to carcasses from G-F pigs fed conventional cornsoybeanmeal diets.4. MycotoxinsCorn is susceptible to molds that can produce mycotoxins prior to harvest, as wellas during storage. The primary mycotoxins of concern to swine are zearalenone,vomitoxin (deoxynivalenol), T-2 toxin, fumonisin, and aflatoxins. In theMidwestern U.S., zearalenone and vomitoxin are the greatest risk.5. Amino acid digestibility is reduced in dark colored DDGS.6. High fiber limits its use in pre-starter diets (< 15 lb livewight)7. Because of the high fiber content, sows will take twice as long to eat their daily feedallotment than sows fed a corn-soybean meal diet.
