Main research question/goal
How can DGS (distillers grains and solubles), a byproduct of bio-ethanol production from grains (sugar beets) be valorized in animal nutrition? We are examining the variation in chemical composition and the nutritive value for cattle, pigs and poultry due to the use of different grains and different production processes. Furthermore, we are focusing on the incorporation of DGS into the diet of dairy cattle, pigs and poultry.
During this project the nutritive value of 7 batches DGS for cattle, pigs and poultry (layers and broilers) is being determined. Aside from the common dry form, wet DGS is also being investigated. We are developing models based on convenient methods for an accurate prediction of the nutritive value of these products. We are checking how much of DGS can be incorporated into the diet of the different animal categories and how the production results are being affected. From the other byproducts of bio-ethanol production in Belgium (distillers grains, distillers solubles) the nutritive value of one representative batch will be examined.
The results of this project are for the benefit of the Flemish animal husbandry and compound feed industry. Animal nutrition advisers, feed analysis laboratories and producers of byproducts show a keen interest as well for our results. A knowledge of the correct nutritive value allows for an adequate use of these byproducts in animal nutrition.
