Alkali Treatment of Cereal Grains. II. Digestion, Ruminal Measurements and Feedlot Performance
TL;DR: No treatment effect was apparent for any carcass characteristic measured except yield grade, which was lower for steers fed NaOH-treated HMC, while both NaOH treatments produced lower fecal pH values than the other treatments.
Journal ArticleDOI
Dietary Supplementation of Fat Increased Milk Fat Percentage without Affecting Ruminal Characteristics in Holstein Cows in a Warm Tropical Environment
TL;DR: Diet supplemented with fat can improve milk yield and milk fat percentage without resulting in disadvantages of ruminal characteristics in cows at early lactation and under warm climate.
Journal ArticleDOI
Response of Fumaric Acid Addition on Methanogenesis, Rumen Fermentation, and Dry Matter Degradability in Diets Containing Wheat Straw and Sorghum or Berseem as Roughage Source
TL;DR: It was concluded from the study that fumaric acid addition in diets varying in roughage to concentrate ratio significantly reduced the methane production without affecting dry matter digestibility and maximum reduction was noticed at 5 mM concentration.
Journal ArticleDOI
Popcorn, Sweet Corn, and Sorghum as Alternative Silage Crops
J. E. Kurle,Craig C. Sheaffer,R. K. Crookston,R. H. Peterson,Hugh Chester-Jones,W. E. Lueschen +5 more
TL;DR: Fodder dry matter yields of popcorn and sweet corn were similar and averaged 42% lower than those of dent corn and sorghum, and returns over production costs of the four crops were lower than expected.
Journal ArticleDOI
Effects of oligosaccharides in a soybean meal-based diet on fermentative and immune responses in broiler chicks challenged with Eimeria acervulina
TL;DR: A SBM-based diet resulted in greater weight gain, feed intake, and short-chain fatty acid production regardless of infection status, and also greater duodenal cytokine expression in E. acervulina- infected chicks, which is hypothesized to be related to the nutrients and oligosaccharides found in SBM.

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.
