Glenda, I think the OP was about the efficacy of a program that recommends a good food plus supplementals additives, including digestive aids like enzymes and probiotics? I'm going ahead on that idea, assuming your caution was referring to the discussion of the clinic in Ohio, rather than the OT stuff on enzymes.
Charlie, I'm not a biochemist, research biologist, or DVM, but I'm fairly sure the penny was corroded by plain old acid, not enzymes. Not incredibly relevant to the topic, but I didn't want people to think I believe that stomach enzymes can digest metal.
There are tons of enzymes in the rumen and other two stomach chambers which precede the true stomach of a ruminant, but no acid until the true stomach. Sometimes cattle pick up bits of metal as they graze and these items can't pass the rest of the way and do the animal harm in various ways. The treatment is to lob a great big smooth magnet down their throats, where it will catch the item and keep going, or even just settle harmlessly to the "bottom" of the chamber where the item resides currently.
Stomach acid, probiotics, and enzymes all have different functions in the gi. Acid is like the sledgehammer - it smashes stuff up to expose the building blocks of what we consume. Enzymes go in and have specific purposes - I'm kind of at a loss here for a good analogy - but what they do is a really unique - and important - thing in nature. They are chains of molecules which are stuctured so that they are reactive with one particular thing. In the gi the enzymes bond with lipids, carbs, etc at various stages to take them from whole food to something the body can use, and then transport them safely where they are needed.
I could get really specific and boring at this point, but I'll spare y'all. What I'm trying to say in short, is that the enzymes that may be in animal tissue, other than in the gi, aren't the same ones that bond with macronutrients in the gi. I do believe whole foods are more easily digested than processed ones, but I don't accept the enzyme thing.
Howsomever. I also believe raw meat is ideal for many dogs - but this notion is based much more on anecdotal evidence than anything. The only thing vaguely scientific I can point to that has contributed to my belief is the fact that ruminants do best on whole foods that are actually
less easy to digest. In other words, a diet of processed concentrated feed requires the addition of antibiotics and coccidistats to keep the animal alive long enough to slaughter. Changing that to whole grains, crushed so they can add minerals and protein sources, is a big improvement.
Best of all is a ruminant allowed to grow naturally on a diet of grass and some whole grains - these animals have the strongest systems and are able to withstand attack from not only stomach ailments, but viruses, parasites, and respiratory ailments. They also have the most resistance to metabolic disorders. Some research seems to indicate that although broken feeds are the "easiest" to digest, that ease of digestion is actually counterproductive to ideal health. There seems to be some role for the challenge of species-appropriate, fresh foods in gi health. Something like processesed concentrated feeds offer the wrong kind of challenge.
I know, dogs aren't sheep. But I see possible parallels that would explain why raw meat can be more desireable for a carnivore, without introducing magic enzyme content.
I've had vets recommend the enzyme for dogs that were emerging from a bout of pancreatitis or even severe gastroenteritis, and it does work like a charm, but once I stop them, I've never noticed a difference in a healthy dog between "on" and "off". I'm the same way about probiotics. I don't offer them all the time. I feed yogurt for different reason, not the probiotics necesarily. If I have a dog I think needs it, I have some high-powered stuff that's for use in livestock, that's guaranteed to deliver the goods.
