Digestibility of energy, and concentration of digestible and metabolizable energy, and ileal amino acid digestibility in conventional and high protein DDGS fed to growing pigs

Distillers dried grains with solubles, or DDGS, is a co-product from the dry-grind ethanol production. It is increasingly in demand for use in livestock feeding, including diets fed to pigs. Conventional DDGS (DDGS-CV) contains approximately 27% crude protein. A high protein DDGS (DDGS-HP) product, containing 38 to 40% crude protein, has recently been developed by Lincolnway Energy by using front end separation that allows for fractionation of the corn kernel before it is fermented. The nutritional value for pigs of the resulting  DDGS-HP has, however, not yet been fully described.

Therefore, two experiments were conducted. The objective of the first experiment was to determine the concentrations of digestible energy (DE) and metabolizable energy (ME) and the apparent total tract digestibility (ATTD) of energy in DDGS-HP and DDGS-CV fed to growing pigs. In the second experiment, the standardized ileal digestibility (SID) of crude protein and amino acids in DDGS-CV and DDGS-HP were compared.

Effects of physicochemical characteristics of feed ingredients on total tract digestibility of dry matter, energy, fiber, and protein by growing pigs

Dietary fiber is resistant to digestion in the small intestine, but is fermented in the large intestine and the resulting short chain fatty acids provide some energy to the pig. Fermentation occurs to a greater or lesser degree depending on the chemical and physical composition of the fiber; soluble fiber is generally fermented to a greater extent than insoluble fiber.

Bulk density, swelling capacity, water binding capacity, and viscosity of diets fed to pigs vary based on the types of fiber present in the diets. Therefore, an experiment was conducted to test the hypothesis that the physicochemical characteristics of feed ingredients are correlated with the concentrations of digestible energy (DE) and metabolizable energy (ME) and the apparent total tract digestibility (ATTD) of energy, dry matter (DM), and nutrients in corn, wheat, soybean meal (SBM), canola meal, distillers dried grains with solubles (DDGS), corn germ meal, copra meal, sugar beet pulp, solka floc, and pectin.
