One of the best constituents of raw green tripe is lactobacillus acidophilus. This is one of the intestinal bacteria that keep unwanted bacteria such as e-coli, salmonella, and listeria from overpopulating and causing health problems. Another beneficial component of raw green tripe is digestive enzymes. The enzymes that help the ruminant digest its meal will give the pet the same benefit. Dogs do not naturally produce amylase, so the nutrients present in the vegetative matter are not readily available to them. Raw green tripe contains not only digestive enzymes but in most cases, some pre-digested green matter as well. This combination of enzymes and nutrients provide pets with a nutritional powerhouse.
