Since 1980, enzion lab manufacture's yeast cultures. We sell the yeast culture undiluted and we incorporate the yeast culture into some of our finished products such as equion, a horse supplement, enzion hoof, calf aid, a calf scour product, super start for calves, hogmate for swine, b2000 plus for cattle and poultry mate for the poultry industry and our quick start probiotic yeast culture paste, calf and cattle bolus. Enzion yeast cultures are added to feeds to stimulate the animals microflora population. The microflora in turn digest fiber and cellulose directly, or, enhance the digestive capacity of the other rumen/digestive system microorganisms. Yeast cultures are used to help overcome harmful microorganisms and/or toxins and their negative effects. They work to stimulate the population of helpful microorganisms.
