Blood plasma concentrations of volatile fatty acids (VFA) in the carotid artery, and the femoral, portal and hepatic veins were measured in pigs fed a low carbohydrate diet (LC group, n=3), and in those fed a high carbohydrate diet (HC group, n=4). The mean body weights at the sampling time were 33.1 for the LC group and 42.2 kg for the HC group. The hepatic endogenous production of not only acetate, but of also propionate and butyrate was found, and it was suggested that the net hepatic…

Influence of meal frequency on postprandial variations in the production and absorption of volatile fatty acids in the digestive tract of conscious pigs.
TLDR
The composition of the VFA mixture was not modified by the length of preprandial fasting, and with this type of diet there was a large predominance of acetic acid followed by propionic and butyric acids (36 and 8.5%, respectively).
Acetate-glucose relationship in growing pigs.
TLDR
There was a reciprocal change in acetate and glucose metabolism in pigs, and glucose, which was considered to have been derived from hepatic glycogen storage, became the dominant blood metabolite in place of the acetate administered with the diet.
Short chain fatty acids in human large intestine, portal, hepatic and venous blood.
TLDR
Data indicate that substantial carbohydrate, and possibly protein, fermentation is occurring in the human large intestine, principally in the caecum and ascending colon and that the large bowel may have a greater role to play in digestion than has previously been ascribed to it.
Utilization of Dietary Fiber from Alfalfa by Growing Swine. II. Volatile Fatty Acid Concentrations in and Disappearance from the Gastrointestinal Tract
Production of volatile fatty acids (VFA) in the cecum and colon and their utilization as an energy source were studied in growing and finishing swine fed diets containing 0, 20, 40 or 60% alfalfa…
Colonic Acetate in the Circulating Acetate Pool of the Infant Pig
TLDR
The gastrointestinal tract was identified as an important site of acetate utilization in the fasted state and it showed that colonic acetate was efficiently absorbed and utilized in the gastrointestinal tract of infant pigs.
Effects of food restriction and starvation-refeeding on volatile fatty acid concentrations in the rat.
TLDR
It is concluded that all VFA are affected by availability of fermentable material to the large bowel microflora but that the disproportionate changes in butyrate may reflect preferential use of this acid by cells of theLarge bowel wall.
Intestinal absorption of end products from digestion of carbohydrates and proteins in the pig
The kinetics of appearance of various nutrients in the portal vein during the postprandial period was studied in conscious pigs by means of a technique based on measurement of the porto-arterial…
Weaning piglets, microbial fermentation, short chain fatty acids and diarrhoea.
TLDR
It is concluded that unweaned and weaned pigs can absorb SCFA and electrolytes immediately after weaning, but that a period of adaptation is required for the optimal absorption of water.

TLDR
The energy supply due to the absorption of VFA became large between the 5th and the 12th hour, and was larger for diets containing poorly digestible or indigestible carbohydrates, which may bridge the energy gap during the interprandial period.

The metabolism of glucose, acetate, palmitate, stearate and oleate in pigs
TLDR
The entry rates in fed pigs were lower than the calculated rates of glucose uptake from the alimentary tract, and the validity of glucose entry rates determined under these conditions is discussed.
Production of endogenous acetate by the liver in lactating ewes.
TLDR
Results indicate that enzymic production of acetate from acetyl-CoA, via carnitine acetyltransferase and acetylcarnitine hydrolase, can adequately account for the substantial production ofacetate by the liver in lactating ewes.
Effect of volatile fatty acids on water and ion absorption from the goat colon.
TLDR
The results support the concept that the colon primarily conserves solute followed by the passive movement of water and indicate a striking influence of VFA on the net transport of Na and water.
The metabolism of acetate in the perfused hind-quarter of the rat.
TLDR
It was calculated that about 25% of the acetate produced in the liver during ethanol oxidation can be consumed in the resting, perfused hind-quarter of the rat, suggesting that the plasma level of free acetate may be one factor in the regulation of acetate uptake in the skeletal muscle.

TLDR
Measurements of the arterial and venous lactate/pyruvate concentration ratios indicate that the NAD-mediated cytoplasmic redox state in the muscle is not changed in the presence of acetate and ethanol, confirming other reports.

Plasma insulin responses to oral and intravenous glucose: studies in normal and diabetic sujbjects.
TLDR
In the noninsulin-requiring maturity-onset diabetic, the glycemic insulinogenic stimulus for a given oral glucose load is significantly greater than in normal subjects and accounts for the excessive plasma insulin responses observed late in the course of an oral glucose tolerance test.
