97 Can Fecal Volatile Fatty Acids be Used as an Indicator of Ruminal Volatile Fatty Acids?

Journal of Animal Science, 2023
Abstract For in vitro digestibility experiments addressing both horses and cattle, feces have long been thought to be an equivalent surrogate for ruminal or cecal inoculum that would eliminate the need for fistulated animals. However, this assumption requires similar microbial and chemical properties among inoculum sources. Validation of

Volatile Cuprous and Silver Salts of Fatty Acids

Nature, 1948
IN a communication in Nature1, one of us (F. K.) reported on a volatile copper compound obtained by thermal decomposition of cupriformate. J. G. Maltby2 directed attention to the work of A. Angel and A. V. Harcourt3, according to whom cuprous acetate forms as a white sublimate when cupriacetate is heated.

Volatile Fatty Acids in Portal Blood of Sheep

Nature, 1949
VOLATILE fatty acids—chiefly acetic, propionic and butyric acids—are formed as a result of the fermentation processes in the rumen of sheep and are absorbed through its wall. With the purpose of investigating the concentration of these acids and other constituents in the portal blood during a digestion cycle, that is, the 12-hour period after feeding ...

The rates of production of volatile fatty acids in the rumen. IV. Individual and total volatile fatty acids

Australian Journal of Agricultural Research, 1967
(1) In sheep fed at 12-hr intervals on roughage diets (lucerne and wheaten hay) total volatile fatty acid production in the rumen has been measured by an isotope dilution procedure based on the infusion of a single 14C-labelled volatile fatty acid.

Pretreatment of macroalgae for volatile fatty acid production

Bioresource Technology, 2013
In this study, a novel method was proposed for the biological pretreatment of macroalgae (Laminaria japonica, Pachymeniopsis elliptica, and Enteromorpha crinita) for production of volatile fatty acid (VFA) by anaerobic fermentation. The amount of VFA produced from 40 g/L of L.

Pseudo catalytic transformation of volatile fatty acids into fatty acid methyl esters

Bioresource Technology, 2016
Instead of anaerobic digestion of biodegradable wastes for producing methane, this work introduced the transformation of acidogenesis products (VFAs) into fatty acid methyl esters (FAMEs) to validate the feasible production of short-chained fatty alcohols via hydrogenation of FAMEs.

Production and Metabolism of Volatile Fatty Acids, Glucose and CO2 in Steers and the Effects of Monensin on Volatile Fatty Acid Kinetics

The Journal of Nutrition, 1983
A study was conducted to determine effects of monensin supplementation on production and interconversion rates of rumen acetate, propionate, and butyrate and plasma acetate. Measurements were made by isotope dilution techniques in four Holstein steers fed a 70% alfalfa hay, 30% corn ration.

The rates of production of volatile fatty acids in the rumen. II Measurements of production of volatile fatty acids in the rumen

Australian Journal of Agricultural Research, 1965
(1) The production of acetic, propionic, and butyric acids was measured in an artificial rumen of the dialysing type: (a) by direct analysis, and (b) by the isotope dilution technique with 14C-labelled fatty acids. Estimates of production by the latter method agreed closely with the direct measurements when due allowance was made for small losses of ...

Origins of the Volatile Fatty Acids in the Rumen

Nature, 1952
MEMBERS of the saturated fatty acid series C1–C7 are formed during the fermentation of wheaten hay or lucerne hay in the rumen of the sheep1,2, and these acids, together with the methane and carbon dioxide also produced, account for a large part of the carbon of the digestible fraction of the fodder.
