Journal ArticleDOI
Influence of the novel urease inhibitor N-(n-butyl) thiophosphoric triamide on ruminant nitrogen metabolism: II. Ruminal nitrogen metabolism, diet digestibility, and nitrogen balance in lambs.
TL;DR: The results suggest that although NBPT is capable of inhibiting ruminal urease short-term, the ruminal microflora may be capable of adapting to chronic NBPT administration, thereby limiting its practical use in improving the utilization of dietary urea.
Journal ArticleDOI
Influence of ration on morphology, histology, and trace mineral content of sheep rumen papillae.
TL;DR: The sequential changes in rumen epithelial development and micromineral content were studied in 15 wethers initially fed a ground control ration and changed to a pelleted feed known to induce ruminal parakeratosis.
Journal ArticleDOI
Effects of Ruminal Versus Duodenal Dosing of Fish Meal on Ruminal Fermentation and Milk Composition
TL;DR: Results from this experiment suggest that effects of fish meal on milk composition are due to postruminal alterations in metabolism, which are similar to those associated with dietary fish meal.
Journal ArticleDOI
The effects of diet supplements and gamma irradiation on dissimilation of low-quality roughages by ruminants: I. Studies on the terylene-bag technique and effects of supplementation of base ration
TL;DR: The terylene-bag technique was evaluated as a means of establishing the rate of intra-ruminal degradation of the following test materials: nassella (Nassella trichotoma), wire grass (Aristida sp.), rice straw, lucerne chaff and cotton lint.
Journal ArticleDOI
Effects of crude glycerin on milk composition, nutrient digestibility and ruminal fermentation of dairy cows fed corn silage-based diets
Pablo Gomes de Paiva,T.A. Del Valle,Elmeson Ferreira de Jesus,Vitor Pereira Bettero,Gustavo Ferreira de Almeida,Ives Cláudio da Silva Bueno,Barry J. Bradford,Francisco Palma Rennó +7 more
TL;DR: The authors evaluated the effects of increasing levels of crude glycerin on dry matter intake, nutrient digestibility, ruminal parameters, blood metabolites, milk yield and composition of dairy cows fed corn silage-based diets.

Journal ArticleDOI
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.
