Digestibility of crude protein and amino acids in Dakota Gold distillers dried grains with solubles (DDGS) fed to pigs is greater than in conventional DDGS

Distillers dried grains with solubles (DDGS) is a co-product of ethanol production. In recent years, companies that produce 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.

Research has shown that adding fat to diets fed to pigs increases the digestibility of amino acids in the diets. However, there is limited information about how reduced oil concentration in DDGS influences the digestibility of protein when fed to pigs. An experiment was conducted to compare the standardized ileal digestibility (SID) of crude protein and amino acids in conventional DDGS and in the low-oil DDGS product Dakota Gold, which is produced using a process that does not involve heating.

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.

Ileal digestibility of amino acids in low-oil DDGS fed to growing pigs

Distillers dried grains with solubles (DDGS) are fed to pigs as a source of energy and amino acids. In recent years, ethanol plants have begun recovering corn oil from DDGS to sell for biodiesel and other uses. Conventional corn DDGS contains 10-12 fat, compared with 5-9% fat in low oil DDGS. Previous research in our lab showed that amino acid digestibility was reduced in low oil DDGS compared with conventional DDGS, but that research used DDGS from only one supplier. An experiment was conducted to compare the digestibility of amino acids in low oil DDGS sourced from multiple different suppliers.

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.
