Nutritional biochemists in Illinois found that corn fiber shows promise as a more economical and healthier ingredient in dog food than some of the fibers now in use.
George Fahey and colleagues point out that the fiber content of dog food varies widely and is often of inferior quality. Many dog foods use fiber from sugar beet pulp. Corn fiber -- available in large amounts as a byproduct of ethanol production -- is an attractive alternative. However, researchers have little information on corn fiber's effects in dogs.
If this shows promise it may be another opportunity for increased sales of distillers grains.
