DDGS - A nutritionist's view

 
DI Franz Waxenecker

 

 

Dried Distillers Grains and Solubles or DDGS is pushing into the feed market, and US usage stands at 9 million tonnes in 2005.

 

Each bio-ethanol plant produces a different quality of DDGS and its composition and nutritional value depends very much on the raw materials used and on the processing techniques, particularly the drying temperature.

 

From a nutritional point of view DDGS is an interesting raw material for fattening pig diets and can be used up to 15 percent of the diet. The pig's gut health is an important factor to take note of if DDGS is to be included in the diet.

 

Other considerations to take into account before including DDGS in the diet include:

    • Protein digestibility
       
    • Feed hygiene
       
    • Existence of fatty acids
       
    • Combination with alternative sources of protein
       
    • Cost value

Being a relatively new source of protein, it would be interesting if DDGS is included in swine diets.

 

Due to the strong smell and taste of DDGS, it is expected that pigs would avoid it and reduce feed intake. The article includes a report on several feed trials of DDGS on pigs at Biomin's trial farm, and its results.
