Currently, the recommended maximum inclusion rate of distiller’s dried grains with solubles (DDGS) in grow-finish swine diets is 10%. However, previous studies conducted at the University of Minnesota have shown that DDGS produced from new ethanol plants in the MN-SD region has higher nutrient levels and digestibility than reported in NRC (1998). Therefore, we conducted a growth performance and...

Two experiments were conducted to determine the DE and ME content of corn distillers dried grains with solubles (corn-DDGS) containing variable ether extract (EE) concentrations and to develop DE and ME prediction equations based on chemical composition. Ether extract content of corn-DDGS ranged from 4.88 to 10.88% (DM basis) among 4 cornDDGS samples in Exp. 1 and from 8.56 to 13.23% (DM basis)...

Five ruminally and duodenally cannulated steers (500 +/- 5 kg of initial BW) were used in a 5 x 5 Latin square to evaluate effects of increasing level of corn distillers dried grains with solubles (DDGS) in growing diets (70% concentrate) on OM intake, site of digestion, ruminal fermentation, and microbial efficiency. Diets consisted of 30% grass hay, 6% concentrated separator by-product, 4% su...

Four crossbred steers (average BW = 478 ± 33 kg) were used in a 4 × 4 Latin square design to determine the effects of dietary concentration of dry corn distillers grains plus solubles (DDGS) in whole corn-based finishing diets on total tract digestion and nutrient balance and excretion. The DDGS were fed at 0% (control), 16.7%, 33.3%, and 50% of dietary DM. All diets contained 10% (DM basis) al...

Lipid peroxidation in feed can negatively affect animal health, growth performance, and meat quality. The objective of this study was to determine the lipid peroxidation level in corn dried distillers grains with solubles (DDGS) samples from 31 U.S. ethanol plants and compare results with a corn sample obtained from a corn processing plant. Lipids from each sample were extracted with hexane and...

Mycotoxins in maize grain intended for ethanol production are enriched in co-product dried distiller's grains and solubles (DDGS) and may be detrimental to yeast in fermentation. This study was conducted to examine the magnitude of fumonisin enrichment in DDGS and to analyze the impacts of insect injury, Fusarium ear rot severity, and fumonisin contamination on final ethanol yield. Samples of n...

A considerable amount of research has been conducted on the effects of feeding DDGS to poultry. Corn DDGS is an excellent feed ingredient for use in layer, broiler, duck and turkey diets and contains approximately 85% of the energy value in corn, has moderate levels of protein and essential amino acids, and is high in available phosphorus. Layer and broiler diets can easily contain up to 10% DD...

Introduction As the ethanol industry grows in Michigan and the U.S., so does the discussion about including distillers dried grains with solubles (DDGS) in swine rations. The DDGS byproduct has the potential to be a nutritious, cost effective replacement for corn, SBM and inorganic phosphorus. Much has been written about feeding DDGS recently in popular magazines and newspapers, including infor...

Dry-grind technology has become the dominant method for ethanol production. During drygrind ethanol production, roughly one-third of the dry grain mass resides in the dried distillers grains with solubles (DDGS) as by-products (i.e., ∼0.8 kg/L ethanol). The energy content residing in the 0.8 kg DDGS is about 20 MJ, compared to the consumption of 1 MJ electricity and 10 MJ thermal energy for pro...
