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 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 کاملA titration approach to identify the capacity for starch digestion in milk-fed calves.
Calf milk replacers (MR) commonly contain 40% to 50% lactose. For economic reasons, starch is of interest as a lactose replacer. Compared with lactose, starch digestion is generally low in calves. It is, however, unknown which enzyme limits the rate of starch digestion. The objectives were to determine which enzyme limits starch digestion and to assess the maximum capacity for starch digestion ...
متن کاملPSA-Physiology: Poultry Digestion and Metabolism
sue samples using Proteinase K digestion method. A 5 ug of the viral RNA was used for the synthesis of cDNA using RevertAid TM First Strand cDNA Synthesis Kit (MBI, Fermentas). The VP2 hypervariable region of the IBDV was amplified using specific primers. A single band of PCR product of the expected size was visualized on 1.5% agarose gel after ethidium bromide staining. Results indicated that ...
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...
