Few areas have impacted pet product design as broadly as microbiome science. In 1995, the “prebiotic” concept was introduced by characterising the major bacterial populations of the human intestine. This concept served as a template of how to view the monogastric intestinal environment in a way that still undergirds much scientific thinking and research in this area. Gregory D. Sunvold at Sunvold Technology investigates the various opportunities in place that are used to expand the use of microbiome tools in pet food products, which will not only benefit pets but also further distinguish products from one another in the marketplace.
