Fructooligosaccharides and Lactobacillus acidophilus Modify Bowel Function and Protein Catabolites Excreted by Healthy Humans
Kelly S. Swanson,Christine M. Grieshop,Elizabeth A. Flickinger,Laura L. Bauer,Bryan W. Wolf,Jomay Chow,Keith A. Garleb,Jennifer A. Williams,George C. Fahey +8 more
TL;DR: FOS and LAC modified several metabolites associated with gut health, with FOS tending to be beneficial (decreased fecal protein catabolites) and Lactobacillus being negative (increased bowel function and fermentative end-product concentrations in feces of healthy humans).
Journal ArticleDOI
Addition of sodium bicarbonate to rations of pre- and postpartum dairy cows.
TL;DR: Compared to controls, cows fed sodium bicarbonate adapted to rations more rapidly postpartum as indicated by increased feed intake during the first 2 wk and by increased milk production During the first 4 wk of the trial.

Effects of Saccharomyces cerevisiae fermentation products on dairy calves: Ruminal fermentation, gastrointestinal morphology, and microbial community
Jianxin Xiao,Gibson Maswayi Alugongo,R. Chung,S.Z. Dong,S.L. Li,I. Yoon,Zhaohai Wu,Zhijun Cao +7 more
TL;DR: In conclusion, Saccharomyces cerevisiae fermentation products improved gastrointestinal morphology, possibly due to increased Butyrivibrio and decreased Prevotella richness of the rumen fluid, which resulted in an increase in butyrate production, and the effect was slightly greater with the higher dosage of SCFP in the starter.

A Novel Resistant Maltodextrin Alters Gastrointestinal Tolerance Factors, Fecal Characteristics, and Fecal Microbiota in Healthy Adult Humans
Nathaniel D. Fastinger,Lisa K. Karr-Lilienthal,Julie K. Spears,Kelly S. Swanson,Krista E. Zinn,Gerardo M. Nava,Kazuhiro Ohkuma,Sumiko Kanahori,Dennis T. Gordon,George C. Fahey +9 more
TL;DR: Resistant maltodextrin supplementation was well tolerated, resulted in favorable fermentation characteristics in the large bowel, and also resulted in a change in bacterial populations.

Gas-liquid partition chromatography: the separation and micro-estimation of volatile fatty acids from formic acid to dodecanoic acid
A. T. James,A. J. P. Martin +1 more
TL;DR: Modifications necessary to the theory of Martin & Synge (1941) to allow for the compressibility of the mobile phase are presented and the application of the gas-liquid partition chromatogram to the separation of volatile fatty acids is described.
Journal ArticleDOI
The utilization of acetic propionic and butyric acids by fattening sheep.
D. G. Armstrong,K. L. Blaxter +1 more
TL;DR: Guggenheim, K. & Bichowsky, L. (1948).
Journal ArticleDOI
Studies on the volatile fatty acids of sheep blood with special reference to formic acid.
Journal ArticleDOI
Gas chromatography of unesterified fatty acids using polyester columns treated with phosphoric acid.
TL;DR: Gas chromatography of unesterified fatty acids is extended to higher fatty acids (C12 and higher) using silicone oil plus β-anthraquinone carboxylic acid and ‘Apiezon L’ grease as liquid phases and considerable tailing of the peak occurs and extremely high column temperatures are required.
