Digestion des glucides chez le monogastrique

摘要: The main dietary carbohydrates are starch, cell wall polysaccharides (cellulose, hemicelluloses and pectins), some monosaccharides (glucose, fructose, galactose, etc.) oligosaccharides (sucrose, lactose, alpha-galactosides, etc.). Recent analytical methods applied to these substances described criticized. A-type starches (cereals), cooked mainly digested in the small intestine of monogastric animals by enzymes salivary glands, pancreas intestinal brush border. total digestibility is almost 100%, whereas it less than 70% for B-type (ex. potato). Cellulose, hemicelluloses, pectins partly microflora large intestine. Fiber varies considerably depends on nature fiber animal species. It 10% chickens, pigs seem digest fibers as well sheep. Hydrothermic treatments usually have no effect starch but can be used starches. Some chemical may improve animals.
