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.

Digestibility of energy in a novel source of soy protein concentrate and in soybean meal fed to weanling pigs

Soybean meal is the main protein source used in diets for pigs in the United States, as well as most countries of the world, due to the high quality of the protein it provides. However, soybean meal also contains antinutritional factors that limit its use in weanling pig diets. Pigs do not secrete the enzyme needed for the hydrolysis of raffinose and stachyose, α-galactosidase, in the small intestine. Therefore, these oligosaccharides are not enzymatically digested, but are instead fermented in the small and large intestines. This results in decreased growth performance and increased incidence of diarrhea when fed to weanling pigs.

Oligosaccharides can be removed from soybean meal using an alcohol extraction process, creating soy protein concentrate. Soy protein concentrate has greater digestibility of most amino acids and greater concentrations of digestible energy (DE) and metabolizable energy (ME) than soybean meal. A new source of soy protein concentrate called Nutrivance (Midwest Ag Enterprises Inc., Marshall, MN) has recently been introduced, which is produced using a process combining non-alcohol extraction and enzymatic treatment of soybean meal. The nutritional value of soy protein concentrate produced using this method has not been determined. Therefore, an experiment was conducted to determine the concentrations of DE and ME in soy protein concentrate and to compare these values to DE and ME in soybean meal.
