Short chain fatty acid absorption by the human large intestine.
Short chain fatty acid absorption from the human rectum has been studied in 46 subjects attending an obesity clinic, using a dialysis bag technique. From a mixed electrolyte solution, acetate concentrations fell from 97.0 to 64.2 mmol/l, and sodium from 97.8 to 85.1 mmol/l with respective net absorption rates of 8.1 and 5.2 mumol/cm2/h. From a solution with mixed short chain fatty acids acetate...
متن کاملFeed restriction reduces short-chain fatty acid absorption across the reticulorumen of beef cattle independent of diet.
The objective of this study was to evaluate the effects of the forage-to-concentrate ratio (F:C) of diets fed before and during short-term feed restriction (FR) on rumen fermentation, absorptive capacity of the reticulorumen, and apparent total tract digestibility. Twenty ovariectomized and ruminally cannulated Angus × Hereford heifers were blocked by BW and individually penned in box stalls (9...
متن کاملAcyl chain length, saturation, and hydrophobicity modulate the efficiency of dietary fatty acid absorption in adult humans.
Intestinal fat absorption is known to be, overall, a highly efficient process, but much less is known about the efficiency with which individual dietary fatty acids (FA) are absorbed by the adult small intestine. We therefore measured the absorption efficiency of the major dietary FA using sucrose polybehenate (SPB) as a nonabsorbable marker and analyzed how it is modulated by acyl chain physic...
متن کاملThe effect of monensin concentration on dry matter intake, ruminal fermentation, short-chain fatty acid absorption, total tract digestibility, and total gastrointestinal barrier function in beef heifers1
In a 4 × 4 Latin square design (24-d periods), 4 ruminally cannulated Hereford × Angus/ Simmental heifers were used to evaluate the effect of increasing levels of monensin concentration on DMI, ruminal fermentation, short-chain fatty acid (SCFA) absorption across the reticulorumen, and total tract barrier function. Heifers were fed a barley-based finishing diet (76% rolled barley grain, 12% bar...
متن کاملAbsorption and exchange of water across rumen epithelium.
The osmotic pressure of solutions in the ventral sac of the rumen of the conscious cow was varied with Na Cl or mannitol. The mucosal blood flow measured by HTO clearance was minimal when the lumen contained an isotonic solution and rose threefold when the rumen was hypo- or hypertonic to plasma by 150 mosmol/kg. Thus osmotic gradients actoss the rumen epithelium stimulated mucosal blood flow. ...
