Ya, Coopslave this discussion was talked indepth in another topic, fairly recently. Good that you brought it up. Trying to gather what was meant in the informations that you gave. Sounds basically, that older chickens can eat barley better than younger chickens -- probably have more digestive enzymes. It indicates to feed digestic enzymes to chickens if feeding barley. I don't think our chicken scratch that we get from our mill here (Surecrop) has barley in the mix). So....getting back to this, how good is barley for feed. Is it worth the effort to figure out what a digestive enzyme is and how to ensure that the birds eat enough of this digestive enzyme to make digestion of barley properly performed. What is digestive enzyme. I need to know. Just cause that is me. What is it? I know in the human, we eat papaya pills if we think that we need a digestive enzyme, particularly for meat digestion. I know I don't use it, but my Husband, some years ago thought it was better if he ate papaya when he consumed meat. He is not great with digestion of some meats, like red meats.
So.....what is the digestive enzyme for chickens. How can it be assured that the chickens eat it to properly digest, if they are fed barley. Sounds like it is an important food digestion enzyme with barley. Now I wonder what on earth is in barley that makes it so indigestible to chickens. I recall posts in that topic on barley digestion and digestion enzymes, that many people don't feed the enzyme and believe that their chickens digest it well.
Does this enzyme occur naturally in free ranged birds from the earth they travel over? I need to know.
Also, on reading the article, below, I have copied the pertinent part, what on earth does the data that enzymes also improve the litter quality of poultry raised on barley-based diets? What the dickens does that mean anyways? I wonder who cares if the litter quality improves. Or maybe they mean that the barley, if not fed digestive enzymes will make a bunch of whole barley grains, and then that will germinate in the soil if it is used to soil amendments. What the dickens!! I NEED to know (ya I drive myself nuts with a need to know, craziness!!). And what the dickens does "the ME values for viscous cereals......" what does ME values mean? Blah, the more I learn the more I need to know....and what the dickens does "viscous cereals" and "intestinal viscosity" mean. Eeks!! Have an awesome day, CynthiaM.

Older birds are more able to utilize barley than are young chicks. The ME values for viscous cereals, such as barley, obtained with adult birds do not appear to be applicable to young chickens. The use of feed enzymes in barley-based diets reduces intestinal viscosity, improving the feeding value of barley. Enzyme supplementation also reduces the variation noted for the feeding value seen with unsupplemented barley-based diets. Feeding barley cultivars with widely different β-glucan levels gives similar growth performance when supplemented with dietary enzymes. Enzymes also improve the litter quality of poultry raised on barley-based diets.
