Volume 3 -Issue 1 | intermediate metabolic activities resulting in heat increment [1]. On this basis, corn has been consistently used as a source of energy because it contains high levels of starch and fat, (compared to soybean meal [SBM]) and relative to other feed ingredients, lower levels of fiber and protein. As such, can undergo metabolic transformations to be utilized for bodymaintenance functions or growth of muscle tissue without resulting in a significant energy loss due to heat increment [1]. Other cereal grains like sorghum, wheat, rye, and barley have relatively lower nutritive value. However, the competition for cost savings in the industry as well as the improvement in feed technology such as the availability of exogenous enzymes, makes the inclusion of non-traditional cereal grains in non-ruminant animal diets more attractive to nutritionists. Thus, farmers are progressively replacing pig feeds with inexpensive cereal grain byproducts like distillers dried grain with solubles (DDGS), wheat middlings (WM), and dried bakery meal.The inclusion of these byproducts (such as DDGS) in a corn SBM-based diet will affect the chemical composition of the pig's diet resulting in less starch or disaccharide fractions and more fibrous
