Digestibility of energy, and total dietary fiber, and concentration of digestible and metabolizable energy in soybean expeller and soybean meal fed to growing pigs

When soybeans are crushed, the oil may be solvent extracted and the resulting defatted soybeans are known as soybean meal (SBM). However, the oil may also be mechanically expelled from the beans and the defatted soybeans resulting from this procedure is an ingredient known as soybean expellers. The expelling procedure is less efficient in removing oil from the beans and soybean expellers, therefore, contain more residual oil than SBM. Soybean expellers can be produced using different technologies, and a new procedure involving a patented high shear dry extrusion procedure was recently developed (Insta-Pro International, Des Moines, IA). There are however, no data for the apparent total tract digestibility (ATTD) of GE and total dietary fiber (TDF) and DE and ME concentrations in the soybean expellers that are produced from this procedure. Therefore, the objective of this research was to test the hypothesis that the ATTD of GE and TDF and concentrations of DE and ME are greater in soybean expellers than in SBM when fed to growing pigs.

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.

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.
