Summary: This study utilized fractionation and enzymatic hydrolysis to improve oil recovery from dried distillers grain with solubles (DDGS), achieving a significant increase in oil content without the need for changes in current ethanol plant design. The combination of cellulase and protease enzymes showed the highest oil recovery rate, indicating promise for increasing profits in ethanol plants operating on slim margins.

Summary: This study compared the effects of increasing the Trp:Lys ratio in diets containing DDGS and a DDGS withdrawal strategy on growth performance and carcass fat iodine value. The results showed that increasing the Trp:Lys ratio improved growth performance and carcass fat iodine value, while the DDGS withdrawal strategy reduced carcass fat iodine value and increased growth rate.

Summary: This study examined 16 DDGS samples from 10 ethanol plants in the Midwest U.S. and measured a series of physical and flowability properties using standard laboratory methods. Results showed various properties such as average moisture content, water activity, shear strength, bulk density, and color parameters. This research represents a step towards a more complete understanding of DDGS and how its properties change with evolving production practices in the ethanol industry.

Summary: There are concerns about using imported soybean meal to feed dairy cows in Europe, but wheat DDGS from European bioethanol production can be a suitable alternative. The inclusion level of European wheat DDGS in high-yielding dairy cow diets is crucial, with the results showing that an inclusion level of at least 22.5% is optimal. The study demonstrates that European wheat DDGS can effectively replace soybean meal in dairy cow diets at high inclusion levels.

Summary: The study successfully utilized corn and rice-based distillers dried grains with solubles (DDGS) as low-cost substrates for the production of Sophorolipids (SLs), which exhibit excellent surface activity and antimicrobial properties, as well as stable performance under various conditions. This method significantly reduced production costs and shows potential for biomedical applications.

Summary: A study was conducted to investigate the effects of heat treatment and heat treatment combined with citric acid on the nutrient digestibility of whole stillage for growing pigs. The results showed that heat treatment or heat treatment combined with citric acid improved the energy digestibility of the stillage, but reduced the digestibility of amino acids.

Summary: To meet the sustainable development of the swine feed industry, new feed resources and processing technologies need to be developed. Co-fermentation of distillers dried grains with solubles (DDGS) and lignocellulosic feedstocks can produce easily digestible and highly nutritious swine feed. This approach can guide cleaner swine farming, alleviate the demand for high-value swine feed, and support the growing pork market.

Summary: Two experiments were conducted to evaluate the suitability of corn DDGS as a protein source for European catfish. The results showed that corn DDGS is a beneficial protein source for European catfish and 30% DDGS can be included in their diet without compromising growth performance and nutrient utilization.

Summary: The addition of dried distillers' grains with solubles (DDGS) in cows' diet can reduce the intake of dry matter, crude protein, and non-fibrous carbohydrates, but has no effect on energy intake, and may increase nutrient digestibility.

Summary: This study aimed to evaluate the effect of feeding diets containing dried distillers' grains with solubles (DDGS) on the performance and milk composition of cows. The results showed that the inclusion of DDGS in the diet reduced the intake of dry matter, crude protein, and non-fibrous carbohydrates, while increasing the intake of ether extract and neutral detergent fiber. However, the energy intake remained unchanged. The digestibility of nutrients and fiber increased with the inclusion of DDGS. The inclusion of DDGS also led to an increase in the concentration of cholesterol before and after feeding. Milk production, energy corrected milk, protein content, and milk urea nitrogen concentration were not affected by the inclusion of DDGS, but milk fat content decreased linearly.
