The use of distillers dried grains with solubles (DDGS) in poultry nutrition

Palmyrah Distillery Spent Wash for Ethanol Production by a Thermotolerant Saccharomyces cerevisiae S1 at 40°C

“…Analysis of spent wash. Total nitrogen 20 , total acidity 22 , total amino acids as tyrosine 21 , reducing sugars 15 and total sugar 20 were determined using standard methods.…”

“…Distillery effluents may be treated or re-utilized to alleviate environmental problems 23 . A number of approaches may be adopted to clean up spent wash. For example, filtering the spent wash and reusing the permeate in the cooking process of the raw materials 12 , bioremediation and decolourization 14,17 , using the distillers dried grains with solubles (DDGS) in poultry feeding 22 , production of biomass and volatile oils 13 , subjecting to liquid hot water pre-treatment and ammonia fibre expansion in addition to enzyme treatments 11 . Research has concentrated on the development of value-added products from spent wash such as fertilizer, SCP (single cell protein) and biogas by anaerobic digestion 5 .…”

Implications for the Feed Industry

“…Pedersen et al (2007) also showed a higher average energy content (22.7 MJ/kg) of ten DDGS samples compared to corn grain. The high energy content of DDGS is associated with high level of fat in the residue (Swiatkiewicz and Koreleski, 2008). The protein content of DDGS has been reported in several experiments to vary from 23 to 32 % (Cromwell et al, 1993, Belyea et al, 2004, Pedersen et al, 2006, Fathi and Afifi, 2008.…”

“…However, the quality of DDGS, for example, has continued to improve with improvement in fermentation, distillation and drying processes. This will re-position the product as a useful feed for non-ruminant animals, especially poultry (Hastad et al, 2003;Swiatkiewicz and Koreleski, 2008). These authors recommended that DDGS could be safely included in starter diets for broilers and turkeys at 5-8 % and 12-15 %, respectively in the grower-finisher phase.…”

Egg performance, egg quality, and nutrient utilization in laying hens fed diets with different levels of rapeseed expeller cake

“…This growth will result in an enlarged quantity of RC available to feed producers. The European Union has supported biofuels production in order to diversify energy supplies, reduce greenhouse gas emission and dependency on oil and to create additional employment in rural areas (Świątkiewicz and Koreleski 2008) Rapeseed cake contains a considerable amount of protein, rich in sulphur amino acids, and, because of its higher crude fat level and lower fibre content, RC is a richer source of metabolizable energy for monogastric animals as compared to solvent-extracted rapeseed meal. The content of anti-nutritive factors, such as glucosinolate and erucic acid, in rapeseed, has been reduced during the last 20 years by plant breeding programmes, so the risk in the use of rapeseed products as animal feed has too been reduced.…”
