Unformatted text preview: digestion between the pig and the cow. (Enzymatic digestion of pig compared to microbial digestion of ruminant, followed by enzymatic digestion.) Pigs start digesting with enzymes beginning with their saliva, but cows do not have salivary amylase. A huge portion of a pig’s consumable energy is in the form of starch, which is more easily digested and can be digested by enzymes the pig excretes itself.
