DDGS in swine diets
Distillers dried grains with solubles (DDGS) is produced from the fuel ethanol industry and is available for inclusion in diets fed to swine. Crude nutrient concentrations, energy and nutrient digestibility values, and effects of including DDGS in diets fed to different categories of swine have been investigated.
The concentration of energy in DDGS is greater than in corn, but because of a lower digestibility of energy in DDGS than in corn, there is no difference in the concentration of digestible and metabolizable energy between DDGS and corn. The apparent and standardized ileal digestibility of amino acids in DDGS does vary among sources but, with the exception of lysine, the variability is no greater than what has been reported for other feed ingredients. The digestibility of phosphorus in DDGS is approximately 59%. This value is greater than in corn. Therefore, if DDGS is included in the diet, less inorganic phosphorus is needed and less phosphorus will be excreted in the manure.
Diets formulated to contain DDGS should be formulated on the basis of digestible amino acids and digestible phosphorus. In general, 10% DDGS can replace approximately 4.25% soybean meal and 5.70% corn, if 0.10% crystalline lysine is included in the diet. DDGS can be included in diets fed to nursery pigs, growing finishing pigs, and sows in amounts of 20% and in diets for gestating sows at 40%. At these inclusion rates, excellent performance of pigs has been reported provided that diets were formulated on the basis of digestible amino acids. Greater inclusion rates are possible, but may not always maximize pig performance.

Implications This review provides relevant information on the utilization of dietary fiber (DF) by pigs and its effects on gut physiological functions, microbiota and health. This review delivers in-depth insight on both negative and positive effects of different fibers inclusion in swine diets. The DF lowers nutrient digestibility in swine. But, the fermentation of DF in the gut affects positively by modulating gut environment and potentially favoring ‘beneficial...

Background Indigestible markers are commonly used in animal nutrition studies to calculate digestibility coefficients, with chromic oxide, titanium dioxide, and acid insoluble ash being the most common in swine research [1]. Physiological aspects associated with gastric emptying or rate of passage are complex and affected by a variety of factors [2, 3]. Rate of passage can be affected by BW [4], feed intake level [5], dietary fiber type and level [6–8], particle size [9],...

Introduction Corn distillers dried grains with solubles (DDGS) is a rich source of protein and amino acids (AA) for pig feed (Stein and Shurson, 2009b). However, the high variation in DDGS AA composition and relatively low AA digestibility may play a role in its limited use in swine diets (Fastinger and Mahan, 2006; Liu, 2011). The ratio of wet distillers grains (WDG) and condensed distillers solubles (CDS) was considered to be one of most important...

Introduction Fiber is a usual component in the pig diet and when included within reasonable levels, it promotes normal gastrointestinal tract function (Wenk, 2001). On the other hand, the negative effect of dietary fiber on energy and nutrient utilization is dependent on its physical and chemical properties which differ among feedstuffs (Lenis et al., 1996). Cereal grains...

Introduction Fuel ethanol production is one of the fastest growing segments in American agriculture. Currently, there are 92 ethanol plants in production, with an additional 23 ethanol plants under construction (www.ethanolrfa.org/industry/statistics, November, 2005). These ethanol plants will have production capacity of 5.6 billion gallons of ethanol per year (Renewable Fuels Association, November, 2005). Approximately...

“Swine Antibiotic Use” By: Paul Walker Thompson Date: 5/27/2016 Though it has been proven that most Human Antibiotic Resistance is due to Human Doctors, not Swine Production; Swine Antibiotic use will decline in the U.S. This is due to our government’s ruling banning Growth Promotants in Swine Feed, and the new requirements on methods of use for Preventative and Curative Antibiotics. The good news is that there are many Alternatives To Antibiotics, such as Minerals (Zinc...

Introduction Grinding of feed ingredients is used to reduce the particle size and increase energy and nutrient digestibility (Wondra et al., 1995d; Laurinen et al., 2000; Mavromichalis et al., 2000; Kim et al., 2002) and it is usually accomplished with the use of either roller mills, hammer mills, or a combination of roller and hammer mills. It is currently recommended that corn grain be milled to an average particle size...

INTRODUCTION Iowa leads the nation in corn and ethanol production. For corn-based ethanol plants, a primary co-product of the process is distillers dried grains with solubles (DDGS). DDGS have been reported to contain high levels of digestible energy and metabolizable energy, digestible amino acids, and available phosphorus (Shurson et al., 2003; Honeyman et al., 2007). Generally, DDGS have been found to contain 2 to 3.5 times more amino acids,...

Introduction
The non-starch polysaccharide content of corn-derived distiller dried gains with soluble (DDGS) is 3-4 times higher compared to corn. Some of the anti-nutritional effects of its high fiber content may be ameliorated with the supplementation of carbohydrases. Our objective was to measure in pigs increases in amino acid (AA) digestibility and energy utilization in a diet with high inclusion of DDGS and...

As feed costs rise and the production of ethanol from corn grain increases, swine producers have ramped up their search for new feed supplements for younger swine. According to studies by Agricultural Research Service (ARS) scientists, feeding dried distiller's grains (DDGS) to piglets can give their immune systems an extra boost. The U.S. ethanol industry generates an estimated 10-14 million metric tons of DDGS annually from the milling of corn grain that yields fermentable...

This study finds that the use of distillers dried grain with solubles (DDGS) as feed is greatly influenced by the development of DDGS products that are available in the market. We find that newer-generation DDGS products have a higher optimal inclusion rate, reaching the maximum allowable rate of 20% for swine, and they have a higher displacement rate of 0.23 for soymeal and 0.93 for corn. Although both traditional and newer-generation DDGS products are primarily used as a corn...

Over the last few years, the use of co-products from the ethanol industry has attracted a lot of attention and research efforts. Distillers dried grains with solubles (DDGS), condensed distillers solubles (CDS), gluten feed, distillers dried grains (DDG) are all co-products of the ethanol industry that are seeing increased use in swine rations both in prepared feeds and in on-farm mixed diets. While the food for fuel debate continues, little attention has been paid to the co-products from...

A total of 112 barrows (average weight of 158 lb) were used in a 65-d growth assay to determine the effects of adding beef tallow (a source of saturated fat) into diets with high inclusion of dried distillers grains with solubles (DDGS). The pigs were sorted by ancestry and blocked by weight with seven pigs/pen and four pens/treatment. Treatments were a corn-soybean, meal-based control and diets having 40% DDGS (US Energy Partners, Russell, KS) with none, 2.5, and 5% added tallow. Feed and...
