The utilization of corn DDGS in swine rations. Some “reminders”
Corn distillers dried grains with solubles (DDGS) is an ingredient that has been successfully incorporated into swine diets for many years. The following is an update on some recent research with this ingredient, plus some ‘tips’ or reminders when incorporating corn DDGS into swine rations.
The nutrient content of corn DDGS can be variable, primarily dependent upon the corn used and the residual oil content in the DDGS. Variability in the energy content of corn DGS does make it difficult to accurately gauge its value an incorporate it into diets. It is recommended that producers work with their nutritionists and suppliers to obtain a consistent product and monitor performance carefully when introducing corn DDGS into the ration.
Current evidence indicates that up to 30% corn DDGS can be included in the diet of growing pigs provided that diets are balanced using NE and SID amino acids. The high fibre content limits the inclusion of corn DDGS to newly weaned piglets; 5% is suggested as the maximum in stage 1 diets. This may increase to 10 or 15% in later stages in the nursery but growth and feed conversion should be monitored. In contrast, the high fibre content makes this an ideal ingredient to be included in the diet of the gestating sow, up to 40% is suggested. In conclusion, corn DDGS can be a very attractive addition to our ingredient ‘toolbox’.
