WHAT IS BETA GLUCAN?

   Beta glucan is a complex carbohydrate or biopolymer of glucose, a simple sugar.

  It is derived from several sources, including yeast, bacteria, fungi and cereals, such as oats, barley and rye. Each type of beta glucan has a unique structure in which glucose is linked together in different ways, giving them physical properties.

   For example, beta 1,3 glucan derived from bacteria and algae is linear, making it useful as a food thickener. Yeast beta glucan is branched with ?,6 and ?,3 glucans, enhancing its ability to bind and stimulate macrophages. The chemical structure of beta 1,3- glucan is dependent on the source and, based on extensive published research, it is widely accepted that the beta 1,3-glucan purified from baker's yeast (Saccharomyces cerevisiae) is the most potent anti-infective beta-glucan immunomodulator . Yeast-derived beta 1,3-glucans work, in part, by stimulating the innate anti-fungal immune mechanisms to fight a range of foreign challenges.

WHAT IS MANNAN OLIGOSACCHARIDES (MOS)

Department of Animal Nutrition and Nutritional Diseases, Faculty of Veterinary Medicine, K›r›kkale University, 71450 K›r›kkale - TURKEY

   Oligosaccharides, including fructo oligosaccharides, galacto oligosaccharides, transgalacto oligosaccharides, and mannan oligosaccharide (MOSs), are one of the most extensively investigated classes of antibiotic alternatives . MOSs, which are derived from the cell wall of Saccharomyces cerevisiae, have shown promising effects, such as decreasing pathogenic microflora of the gut, stimulating a strong immune response, and elevating the strength of the intestinal mucosa in studies with poultry. By balancing the intestinal environment and stimulating the immune response, MOSs have been shown to increase growth in broilers, turkeys, and swine.
