Three sheep fitted with a ruminal cannula and an abomasal catheter were used to study water kinetics and absorption of VFA infused continuously into the rumen. The effects of changing VFA concentrations in the rumen by shifting VFA infusion rates were investigated in an experiment with a 3 x 3 Latin square design. On experimental days, the animals received the basal infusion rate of VFA (271 mmol/h) during the first 2 h. Each animal then received VFA at a different rate (135, 394, or 511 mmol/h…

Effect of increasing ruminal butyrate absorption on splanchnic metabolism of volatile fatty acids absorbed from the washed reticulorumen of steers.
TLDR
The capacity to metabolizebutyrate by the ruminal epithelium and liver is limited and if butyrate absorption exceeds the metabolic capacity, it affects rumen epithelial and hepatic nutrient metabolism and affects the nutrient supply of peripheral tissues.
Effects of ruminal ammonia and butyrate concentrations on reticuloruminal epithelial blood flow and volatile fatty acid absorption kinetics under washed reticulorumen conditions in lactating dairy cows.
The effect of reticuloruminal epithelial blood flow on the absorption of propionate as a volatile fatty acid (VFA) marker in 8 lactating Holstein cows was studied under washed rumen conditions. The…

TLDR
It is concluded that this study could not provide any evidence that ruminal VFA proportions are unrepresentative of the proportions of net production.
Total volatile fatty acid concentrations are unreliable estimators of treatment effects on ruminal fermentation in vivo.
TLDR
The varying relationship of [V FA] to VFAmol indicates that [VFA] is not an appropriate measure to evaluate the progress or effect of treatments onRuminal fermentation in vivo, and alternate evaluations for in vivo ruminal fermentation are needed.
Effect of butyrate infusion into the rumen on butyrate flow to the duodenum, selected gene expression in the duodenum epithelium, and nutrient digestion in sheep.
TLDR
The aim of the study was to determine the effect ofbutyrate infusion into the rumen on butyrate flow to the duodenum, expression of short-chain fatty acid (SCFA) transporters and receptors and G protein coupled receptor-41 and -43 in theduodenal epithelium and nutrient digestion in sheep.
Ruminal pH regulation and nutritional consequences of low pH
Fermentation of RUMINANT NUTRITION SYMPOSIUM : Role of fermentation acid absorption in the regulation of ruminal pH 1 , 2
Highly fermentable diets are rapidly converted to organic acids [i.e., short-chain fatty acids (SCFA) and lactic acid] within the rumen. The resulting release of protons can constitute a challenge to…
EFFECTS OF RUMEN EXPOSURE TO ANISE OIL ON RUMINAL FERMENTATION AND BIOHYDROGENATION OF N – 3 POLYUNSATURATED FATTY ACIDS
This study evaluated the effect of four weeks of microbial exposure to anise oil (ANO) on the fermentation activities of ruminal micro-organisms and the biohydrogenation of n -3 polyunsaturated fatty…
Mechanisms of acid absorption in the rumen and impacts on subacute sumen acidosis
A distinguishing feature of ruminants is that they rely on anaerobic fermentation of feeds in the rumen and reticulum (collectively termed the reticulo-rumen) to supply metabolizable energy in the…
Ruminant Nutrition Symposium: Role of fermentation acid absorption in the regulation of ruminal pH.
TLDR
It is suggested that the interacting transport processes for SCFA, urea, and ammonia represent evolutionary adaptations of ruminants to actively coordinate energy fermentation, protein assimilation, and pH regulation in the rumen.

Osmotic pressure, water kinetics and volatile fatty acid absorption in the rumen of sheep sustained by intragastric infusions
TLDR
Rumen OP seems to be important in defining water movement across the rumen wall and, hence, partitioning between absorption and outflow, and as rumen OP was increased there was also a decline in the absorption rate of V FA, resulting in the accumulation of VFA (especially acetate) in theRumen and a consequent fall in rumen pH.

Absorption of volatile fatty acids from the rumen of lactating dairy cows as influenced by volatile fatty acid concentration, pH and rumen liquid volume
TLDR
Results indicate that relative concentrations of VFA in rumen fluid might not represent relative production rates and that attempts to estimate individual VFA production from substrate digestion must take account of pH and VFA concentration.

Abstract Three rumen fistulated and catheterized sheep were used to study portal recovery of continuously intraruminally infused short-chain fatty acids (SCFA). Each sheep received six treatments: 0,…

Effect of undernutrition on the ability of the sheep rumen to absorb volatile fatty acids.
TLDR
The ability of the rumen to absorb the same quantity of VFA with 4 animals previously fed with 2 levels of intake was tested and VFA absorption rates (mmol/h) were significantly reduced after undernutrition.
Disappearance and passage of propionic acid from the rumen of the beef steer.
TLDR
There was insufficient evidence to conclude that fractional dilution rate or ruminal volume were similarly related to their in situ production rates, but the digestive tract distal to the rumen is likely an important site of propionate absorption in cattle when propionic acid production is high.
Short‐chain fatty acids in sheep: Portal appearance rates following high intraruminal loads
The portal recovery of SCFA (short‐chain fatty acids) infused intraruminally as a single load was investigated in sheep adapted to a hay (H) or a concentrate/straw (CS) diet. The treatments were…
Effect of composition of ruminally-infused short-chain fatty acids on net fluxes of nutrients across portal-drained viscera in underfed ewes
TLDR
Energetic summation of portal net release was not significantly different between the three SCFA infusions, although it tended to be lower with high-butyrate infusion, which may be related to the higher trophic effect of butyrate on the digestive mucosa.
