Distillers dried grains with solubles

Reduced feed costs with use of DDGS

By Dr. Hans H. Stein

January, 2011

Although the cost of DDGS has increased during the last 6 months, there are still significant savings associated with the use of DDGS in swine diets. DDGS will replace corn, soybean meal, and inorganic phosphorus sources in diets fed to pigs. Because the costs of these ingredients have increased more than the cost of DDGS, it is a good idea to include DDGS in the diets to help reduce feed costs. With current prices for corn, soybean meal, and DDGS, costs of swine diets are reduced by 7 to 9 dollars per ton for each 10% DDGS that are included in the diets (Figure 1). In most cases, 30% DDGS can be included in diets fed to all categories of pigs if an average or above average quality of DDGS is used and if diets are properly balanced for all nutrients. If 30% DDGS is included in diets fed to sows, weanling pigs, and growing-finishing pigs, the total cost savings by using DDGS is approximately 10 dollars per market pig produced.

Digestibility of dietary fiber in distillers coproducts fed to growing pigs

Fiber digestibility is one factor in the efficiency of energy utilization in fibrous feed ingredients. Fiber can be digested via fermentation in the ileum or in the hindgut.

Fecal matter and ileal digesta from pigs fed one of 29 different diets were analyzed to measure the apparent ileal digestibility (AID) and the apparent total tract digestibility (ATTD) of dietary fiber in different sources of distillers dried grains with solubles (DDGS) and to calculate hindgut fermentation (HGF) of dietary fiber in DDGS fed to growing pigs.

Keep an eye on fat concentrations in DDGS

By Dr. Hans H. Stein

March 2010

Many companies that are producing DDGS have started to centrifuge or skim off the fat from the DDGS. These companies then sell the fat for biodiesel production at a price that is much greater than what they can usually obtain for DDGS. The consequence of this practice is that the concentration of fat in DDGS is reduced from 10 to 11% in conventional DDGS to between 6 and 8 % in the centrifuged low-fat DDGS. This DDGS has a reduced concentration of energy and has, therefore, also a reduced value when fed to livestock. Conventional DDGS with 10 to 11% fat has a concentration of digestible energy that is similar to that in corn. However, if the concentration of fat in DDGS is reduced by 3 to 5% then the energy value of that product is reduced considerably.
