Distillers dried grains with solubles

Digestibility of amino acids in a high protein corn product fed to growing pigs

Corn coproducts produced from the ethanol industry are often used in diets for pigs. A new source of corn protein (NexPro; Flint Hills Resources, Wichita, KS) has been developed, but at this time there is limited information about the nutritional value of this new source of corn protein. Therefore, the objective of this experiment was to test the hypothesis that the standardized ileal digestibility (SID) of amino acids  in corn protein is greater than in 2 sources of distillers dried grains with solubles (DDGS; i.e., DDGS-1 and DDGS-2) when fed to growing pigs.

Digestibility of energy and phosphorus and concentration of metabolizable energy in a new source of high-protein distillers dried grains fed to growing pigs

Recently a high-protein distillers dried grains (HP-DDGS; ProCap DDGS, Marquis Energy, Hennepin, IL) was developed and the HP-DDGS has greater concentrations of CP and fat, but contains less fiber compared with conventional DDGS, which may affect the digestibility of energy and P and concentrations of DE and ME. There are, however, no data for the nutritional value of this new source of DDGS. Therefore, 2 experiments were conducted to test the hypothesis that concentrations of DE and ME, and standardized total tract digestibility (STTD) of P in HP-DDGS are greater than in conventional DDGS.

Digestibility of amino acids in a new source of distillers dried grains with solubles fed to growing pigs

Distillers dried grains with solubles (DDGS) is a co-product from the dry-grind ethanol production. However, quality and nutrient content of DDGS may differ among sources and origins and new technologies allow for production of DDGS with different chemical compositions as well as nutritional values. Recently a high-protein distillers dried grains (HP-DDG; ProCap DDGS, Marquis Energy, Hennepin, IL) was introduced and the HP-DDG has greater concentrations of CP and fat, but contains less fiber compared with conventional DDGS, which may affect the digestibility of AA in HP-DDG compared with conventional DDGS. There are, however, no data for the digestibility of AA in this new source of DDGS. Therefore, the objective of this research was to test the hypothesis that standardized ileal digestibility (SID) of AA in HP-DDG is greater than in conventional DDGS when fed to growing pigs.

Effects of Dakota Gold distillers dried grains with solubles (DDGS) and conventional DDGS on growth performance and carcass quality of pigs fed diets as meal or as pellets

Dakota Gold is a low-oil source of distillers dried grains with solubles (DDGS) produced using a cold-fermentation process. Recent research conducted by the Stein Monogastric Nutrition Laboratory has demonstrated that the standardized ileal digestibility (SID) of amino acids is greater in Dakota Gold than in conventional DDGS, but Dakota Gold contains less metabolizable energy (ME) than conventional DDGS.

An experiment was conducted to determine effects on growth performance and carcass characteristics of feeding Dakota Gold or conventional DDGS to pigs from weaning to market. Because limited information exists about effects of pelleting on growth performance of pigs fed diets that contain DDGS, this research also tested the effects of feeding diets containing either Dakota Gold or conventional DDGS in a meal form or in a pelleted form.

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.

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.
