Fractionation of Distillers Dried Grains with Solubles (DDGS) through a Destoner
نویسندگان
چکیده
A destoner fractionation process was used to separate distillers dried grains with solubles (DDGS) into streams with various compositions. Results showed that destoner fractionation was somewhat efficient and effective. Runs with 8° angle and 27.5 percent air flow resulted in the highest value of protein and oil, which the light fraction had 28.15% protein, 10.50% oil, while the heavy fraction had 31.30% protein and 17.20% oil. Particle size distribution had a positive correlation coefficient (0.93) with oil parameters and a negative correlation coefficient (-0.96) with moisture parameters. Fiber had no relationship with particle size, and protein had a weak correlation coefficient with (-0.54) to particle size.

The objective of this work was to evaluate the inclusion of distillers dried grains with solubles (DDGS) as substitution for soybean meal in Hisex Brown laying hen diets with or without enzyme or vitamin E supplementation on productive performance. A total number of 180 Hisex Brown laying hens at 26 weeks of age were randomly divided into 15 treatment groups in a 5 × 3 factorial design experime...
متن کاملUtilization of DDGS by Cattle
Distillers grains with solubles (DDGS), the major byproduct of ethanol production, is a good protein and energy feed for cattle. The DDGS can be fed wet or dried with animal performance usually similar when fed as wet or dried products; however, some research results favored the wet products. Cattle diets can contain DDGS as replacements for portions of both concentrates and forages, although D...

Distillers dried grains with solubles (DDGS) is produced from the fuel ethanol industry and is available for inclusion in diets fed to swine. During recent years, several research projects have been completed to investigate the feeding value of DDGS. Crude nutrient concentrations, energy and nutrient digestibility values, and effects of including DDGS in diets fed to different categories of swi...

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...

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...
