Therefore, any heating or roasting should be controlled. Brewers and distillers grains can be fed either dry or wet. The drying process increases the rumen resistant protein. Little starch is present in these products because it has been utilized in the fermentation process. What is left is mostly protein and fiber.
Brewers grains are similar to corn silage in energy content.
Corn gluten feed is a byproduct of corn syrup manufacturing. This feed has protein that is mostly degradable in the rumen and is not considered a source of rumen resistant protein. Energy is similar to some grains. Corn gluten feed is often an economical feed to use in rations. Citrus pulp is a source of digestible fiber and adds bulk to rations.
