Feeding Dried Distillers Grain Solubles to Swine

David Stender, swine field specialist


Technology in the swine industry is rapidly advancing. Producers are pressured to keep up with the advances in technology. In Dec 2002, 55 producers looking to understand advantages and cautions concerning feeding Dry Distiller Grain Solubles (DDGS) to swine. Participants attending had control over 711,100 finishing pigs and 37,627 breeding stock. A significant portion of swine production in Northwest Iowa. I helped develop a DDGS analyzer software to help producers in Northwest Iowa make more informed decisions regarding the purchase of DDGS from a local ethanol plant. The software was sent home on a floppy disk at the meeting and send to other producers inquiring after the workshop via email attachment.


Surveys were mailed out 10 months following the program to check for changed behavior and impact from the previous programming efforts. Twenty-two surveys were returned and the results that participants reported are as follows:

A few examples of the most important ideas learned by producers include:
Cost advantage, ability to use in swine diets and pricing rations;
Health benefits, ileitis benefits;
Effects on manure, manure management issues;
Feeding rate, nutrient profile. Pricing thumb rules were great!
Incorporation of DDGS through our feed business;
The high level of lysine in DDGS;
Quality of distillers, Quality control of DDGS, Variability in product;
Ration diet formulation, added oil in DDGS;
Toxin levels of by-product, Monitor myco toxin levels more frequently.
Seven producers were able to calculate the economic impact to their operations. The average benefit were $3300 per operation.
