Electronic Theses and Dissertations
The high fiber content of corn dried distillers’ grains with solubles (DDGS) can limit its utilization in swine diets. Pretreatment with heat and enzymatic predigestion of whole stillage (WS; slurry material that is dried into DDGS) can alleviate negative effects of dietary fiber and can improve digestive and fermentation characteristics of the feedstuff. However, optimal time and temperature of the heat pretreatment of WS, and best enzymes for predigestion of WS have not been identified. Experiments were conducted to identify optimal conditions for heat pretreatment and multienzyme predigestion of WS for pigs. First experiment was conducted to identify optimal temperature …
