Carbohydrates from a perhaps surprising source—pine trees—may have beneficial effects on dogs’ digestive-system health, according to collaborative studies by Agricultural Research Service, university, and corporate scientists.

The carbs, predominantly a group known as “GGMOs”—short for galactoglucomannan oligosaccharides—are a key ingredient in Previda, an all-natural dietary ingredient marketed to makers of pet food, aquaculture feed, and other animal-nutrition products.

ARS chemist Neil P.J. Price began his studies of these fiber-rich carbs in 2007, working under the auspices of a cooperative agreement with Temple-Inland, a Texas-based producer of lumber, fiberboard, and other wood products made from loblolly, longleaf, and other kinds of pine trees often referred to as “southern yellow pine.”
