Digestibility of amino acids, fiber, energy, and concentrations of digestible and metabolizable energy in conventional and extruded yellow dent corn, wheat, and sorghum fed to growing pigs

Extrusion of cereal grains may be used to improve nutrient digestibility in cereal grains because addition of heat and pressure in combination with addition of moisture during the extrusion may gelatinize the starch, which results in an increase in starch digestibility. It is also possible that AA and energy digestibility are increased by the extrusion, but data to verify this hypothesis have not been published. Therefore, the objective of these experiments was to test the hypothesis that the ileal digestibility of AA and starch and the apparent total tract digestibility (ATTD) of ADF, NDF, and GE as well as the concentrations of DE and ME in corn, wheat, and sorghum are increased by extrusion.

Digestibility of energy and nutrients, and concentrations of DE and ME, in Dakota Gold DDGS fed to pigs

In recent years, companies that produce distillers dried grains with solubles (DDGS) have begun to remove some of the corn oil for use in biodiesel production. Conventional DDGS contains 10-12% fat, compared with 6-9% in low-oil DDGS.

There is limited information about how oil concentration in DDGS influences the digestibility of energy, fiber, and fat when fed to pigs. Therefore, an experiment was conducted to determine the apparent total tract digestibility (ATTD) of energy, neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid hydrolyzed ether extract (AEE), as well as the concentrations of digestible energy (DE) and metabolizable energy (ME) in two sources of DDGS. One source was a conventional DDGS, and the other was Dakota Gold, a low-oil DDGS.

Digestibility of NDF and concentration of DE and ME in low-oil DDGS fed to growing pigs

In recent years, ethanol plants have begun extracting more oil from the solubles left over after fermentation. The resulting low oil distillers dried grains with solubles (DDGS) contain less digestible energy (DE) and metabolizable energy (ME) than traditional DDGS.

The fat content of the diet affects the digestibility of energy and nutrients. Because the production of low oil DDGS is a relatively new development, it has not been established that digestibility values are the same across suppliers. Therefore, an experiment was conducted to measure the apparent total tract digestibility (ATTD) of neutral detergent fiber (NDF) and the concentration of DE and ME among DDGS samples from different suppliers.
