Two experiments were conducted to measure the reactive Lys concentration in corn distillers dried grains with solubles (DDGS). In expt 1, reactive Lys was measured in 33 sources of DDGS using two procedures: the homoarginine procedure and the furosine procedure. The concentration of reactive Lys in DDGS was then correlated with the concentration of standardized ileal digestible (SID) Lys in DDG...

A completely randomized design with 7 replications (n = 7, treatments = 5 with 8 subsamples per treatment) was used to evaluate the effects of feeding various levels of distillers dried grains with solubles (DDGS; 0, 6, 12, 18, and 24%) on broiler breast and thigh meat quality. Broilers were harvested in a pilot scale processing plant with commercial prototype equipment at 42 d of age. The righ...

A major emphasis on ethanol production in the US has led to the construction of new ethanol plants and an increased production of distillers dried grains plus solubles (DDGS). In the past DDGS came largely from the beverage industry and consisted of several grains used during fermentation. Recently, a majority of the DDGS produced is from corn fermentation for ethanol production. Little researc...

The feeding value of extruded and nonextruded wheat and corn distillers dried grains with solubles (DDGS) for broilers was evaluated in 2 experiments. In experiment 1, male broilers (n=360) housed in battery cages were fed assay diets that included either 15 or 30% wheat or corn DDGS (extruded or not) in relation to a basal diet from d 21 to 28. Birds were killed on d 28 and ileal digesta was c...

Dried corn distillers grains with solubles (DDGS) fed to swine may adversely affect carcass quality due to the high concentration of unsaturated fat. Feeding CLA enhances pork quality when unsaturated fat is contained in the diet. The effects of CLA on growth and pork quality were evaluated in pigs fed DDGS. Diets containing 0, 20, or 40% DDGS were fed to pigs beginning 30 d before slaughter. A...

There is currently much ongoing research and interest for developing new processing technologies to produce corn distillers dried grains with solubles (DDGS). The current study evaluated a high protein (HP) DDGS and a dehydrated corn germ meal which are the products that can be produced by a modifi ed dry milling process. To evaluate the nutritional characteristics of these products, a chick ex...

A study was conducted to test the inclusion rates of corn dried distillers grains with solubles (DDGS) in laying hen diets on egg production (EP) parameters for a full production cycle. Two hundred eighty-eight Bovan Single Comb White Leghorn laying hens were fed diets containing 0, 5, 10, 15, 20, or 25% DDGS from 24 to 46 wk and 47 to 76 wk of age for Phase I and Phase II, respectively. The di...

An experiment was conducted to measure DE and ME and the apparent total tract digestibility (ATTD) of energy, N, and P in distillers dried grains with solubles (DDGS) fed to growing pigs. Ten sources of DDGS were obtained from ethanol plants in South Dakota and Minnesota, and 11 diets were formulated. One diet was based on corn (96.8%), limestone, salt, vitamins, and microminerals. Ten addition...

A study was conducted to evaluate feed intake, ADG, carcass quality, eating behavior, and blood metabolites in feedlot beef steers fed diets that varied in proportion of wheat dried distillers grains with solubles (DDGS) replacing barley grain or barley silage. Two hundred crossbred steers (BW = 489 ± 30 kg) were blocked by BW and randomly allotted to 20 pens (5 pens per treatment). Steers were...

Increase in the demand for ethanol has resulted in growth in the dry grind (DG) ethanol industry. In DG processing, the whole corn kernel is fermented, resulting in two main coproducts, ethanol and distillers dried grains with solubles (DDGS). Marketing of DDGS is critical to the economic stability of DG plants. The composition of DDGS can vary considerably; this reduces market value. Factors t...
