Examples of some of these products are enzymes and probiotics. The addition of very minute amounts of those ingredients into a typical feed ration will allow the animal to obtain more nutritive value. If you take a higher-fibre, lower-digestible ingredient, an animal would have a lot more waste excreted and suddenly the animal gets more energy and more value out of it. You can save money by using lower-cost ingredients to raise an animal.
