Enhancing gut health and uptake of nutrients by using carbohydrate-degrading enzymes

Dalibard P., . and Liu Y. G., . (2007) Enhancing gut health and uptake of nutrients by using carbohydrate-degrading enzymes. [Proceedings Paper]

Digestion and absorption of feeds are sophisticated dynamic interactions among dietary substances including both the desirable and the undesirable endogenous enzymes gut microbes and epithelial cells on the villi and much of this complex remains unknown by far. For poultry and pigs it is known the use of feed enzymes generates noticeable benefits for wheat and barley diets and somewhat inconsistent outcome on corn-based diets. Comparing with the mechanism of phytase being rather straight forward our knowledge on enzymes targeting nonstarch polysaccharides is still very limited especially for corn-based diets. Study results prove that not only can enzymes alter intestinal microbial activities and gas production of digesta but also morphology throughout of the small intestines of the young pigs. Variable responses of enzyme supplementation are largely due to dynamic alterations of the intestinal parameters in accordance with the presence of dietary undesirable substances rearing environment and health status. Thus a large number of in vivo metabolic studies is required to define response magnitude of any given enzyme product.

Abstract

Digestion and absorption of feeds are sophisticated dynamic interactions among dietary substances including both the desirable and the undesirable endogenous enzymes gut microbes and epithelial cells on the villi and much of this complex remains unknown by far. For poultry and pigs it is known the use of feed enzymes generates noticeable benefits for wheat and barley diets and somewhat inconsistent outcome on corn-based diets. Comparing with the mechanism of phytase being rather straight forward our knowledge on enzymes targeting nonstarch polysaccharides is still very limited especially for corn-based diets. Study results prove that not only can enzymes alter intestinal microbial activities and gas production of digesta but also morphology throughout of the small intestines of the young pigs. Variable responses of enzyme supplementation are largely due to dynamic alterations of the intestinal parameters in accordance with the presence of dietary undesirable substances rearing environment and health status. Thus a large number of in vivo metabolic studies is required to define response magnitude of any given enzyme product.
