The foods and nutritional supplements fed to pigs and other farm animals have an important effect on the gastrointestinal health of the herd. Animal scientists test different combinations of feed and supplements, and then track the occurrence of disease. They also examine the resulting health of the digestive system using images like this cross-section of a pig intestine.
