Hill's Pet Nutrition issued US patent for exopolysaccharide containing food

ALEXANDRIA, Virginia , October 31, 2013 () – According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Cheuk, Wai (San Marcos, CA); Khoo, Christina (Lawrence, KS), filed on March 17, 2008, was published online on October 22, 2013.

The assignee for this patent, patent number 8563029, is Hill's Pet Nutrition, Inc. (Topeka, KS).

Reporters obtained the following quote from the background information supplied by the inventors: "All mammals require a healthy diet and proper digestion for continued growth and ordinary well being. However, gastrointestinal distress interferes with the ordinary digestion of food. Some of these problems can be quite serious and demand serious medical attention such as Crohn's disease; irritable bowel syndrome, other chronic conditions and the like. Others are of a less serious condition and can be essentially self-limiting such as food borne virus, intestinal flu and the like. Almost all gastrointestinal disorders are accompanied by diarrhea, a loose watery stool which can be extremely unpleasant to the mammal harboring the condition or to a pet owner who must clean up after the pet evacuates, particularly if on a chronic basis.

"It has also been found that some pet foods tend to create or exacerbate a diarrhea condition. For example, as described in U.S. Pat. No. 6,280,779 issued Aug. 28, 2001, diarrhea can be a significant problem with pets consuming a 'chunks and gravy' diet. In particular, the presence of significant quantities of gum in a 'chunks and gravy' diet, primarily chemically modified starches or gums, but even, to a lesser extent, ordinary natural starches and gums has been associated with diarrhea in pets."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "This invention is directed to compositions and methods for preventing or reducing diarrhea in a mammal.
