How to Cook Beef Tripe. Beef tripe is a type of food derived from the lining of one of a cow's four stomach chambers. Tripe (which can come from many other animals, but usually hoofed farm animals) is eaten all over the world as an important ingredient in many local cuisines.
Tripe is a muscle meat, but also considered offal and should be fed as part of the 70-80% meat content in your dogs raw diet. To decide how much to feed as part of this percentage, we try to visualise the whole animal and estimate what proportion or percentage of it would be made up of its tripe, or stomach linings.ripe is a muscle meat, but also considered offal and should be fed as part of the 70-80% meat content in your dogs raw diet.
