The Use of a Mannanoligosaccharide as a Feed Supplement to Enhance Mink Kit Survivability and Growth

摘要

Enteric pathogens must attach to the mucosal surface of the gut wall to establish themselves in the gastrointestinal tract. Because attachment is often mediated through binding of bacterial lectins to gut receptors containing the sugar D-mannose, inhi bition of bacterial attachment can be accomplished by addition of mannose, or similar sugars, to the diet Because relatively high concentrations of mannose are required to control colonization of pathogenic bacteria, the cost of using pure mannose in com mercial animal production is prohibitive, even for short periods of time However, mannose-based sugars occur naturally, such as in yeast cell walls Recently, mannanoligosaccharides (MOS), derived from yeast cell walls, have been evaluated as to their abi lity to bind enteric pathogens (Spring et al., 2000).
