Journal ArticleDOI
Comparison of warm season and cool season forages for dairy grazing systems in continuous culture.
TL;DR: Overall, fermentation of warm-season grasses was similar to the cool-season Grasses and legumes which indicate dairy producers may use warm- season grasses without concerns about negative impact on rumen health.

TL;DR: The effects of Taiwan grass cutting interval and partial substitution with duckweed on dry matter intake, in vivo DM digestibility, and digestibility of organic matter, crude protein, neutral, NDFD, neutral and acid detergent fiber, as well as on nitrogen balance, ruminal pH, production of volatile fatty acids (VFA) and ammonia nitrogen (NH 3 –N), was evaluated.
Journal ArticleDOI
Effect of Different Silages for TMR on In vitro Rumen Simulative Fermentation
TL;DR: It can be concluded from the present study that WCBS and IRGS are of almost an equivalent nutritional value when incubated in a TMR form, however WCBS resulted in lower A/P ratios than IRGS-TMR, which is indicative of a more energy efficient diet.
Journal ArticleDOI
Effects of the Brown Seaweed Residues Supplementation on In Vitro Fermentation and Milk Production and Composition of Lactating Dairy Cows
TL;DR: It could be summarized that BSR may stabilize rumen pH, and it could improve milk yield and CLA content in milk with more than 4% of diet, and could be beneficially used in dairy diets.

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.
