Starch digestion capacity of poultry.
Starch is quantitatively the most important nutrient in poultry diets and will to a large extent be present as intact starch granules due to very limited extent of gelatinization during pelleting. Although native starch is difficult to digest due to a semi-crystalline structure, even fast-growing broiler chickens appears to be able to digest this starch more or less completely during passage th...
متن کاملGastrointestinal digestion of starch. I. The action of oligo-1,6-glucosidase on branched saccharides.
Digestion of starch in mammals occurs chiefly in the mouth and small intestine through the catalytic activity of ar-amylase and maltase (a-glucosidase). Extensive cw-amylolysis of amylose and amylopectin results in the formation of maltose, glucose, and a mixture of branched oligosaccharides (cr-amylase dextrins) (1). The latter compounds, whose structure is currently being investigated by seve...
متن کاملStarch Digestion in the Horse
The rate and extent of starch digestion is determined by: 1. properties of the starch granule; 2. the effect of processing; 3. associated food structures (plant cell walls); 4. transit time through the small intestine; 5. the availability and concentration of enzymes. These factors will affect the glycemic response of the horse to feeding and the subsequent production of insulin. Resistant star...
متن کاملRuminal and Postruminal Starch Digestion by Cattle
Grains are fed to livestock primarily to supply energy, and most of the digestible energy in cereal grains comes from starch. To maximize starch digestion by livestock, corn and sorghum grain must be processed. For nonruminants, starch from finely ground grain is fully digested, but for ruminants fed high concentrate diets, finely ground grain often causes metabolic diseases. Hence, rather than...
متن کاملCharacterization of Digestion Resistance Sweet Potato Starch Phosphodiester
Purpose: To analyze the physicochemical properties and in vitro digestibility of sweet potato starch phosphodiester prepared using sodium trimetaphosphate. Methods: The physicochemical properties of sweet potato starch phosphodiester were analyzed by using infrared spectrometry (IR), differential scanning calorimetry (DSC) and rapid visco-analyser (RVA). In addition, an in vitro digestibility m...
