Journal ArticleDOI
Effect of the particle size of maize, rice, and sorghum in extruded diets for dogs on starch gelatinization, digestibility, and the fecal concentration of fermentation products.
Rodrigo Sousa Bazolli,Ricardo Souza Vasconcellos,L. D. de-Oliveira,F. C. Sá,Gener Tadeu Pereira,Aulus Cavalieri Carciofi +5 more
TL;DR: For dogs fed different particle sizes of the cereal starches in the extruded diets, the digestibility and fecal characteristics were affected, and this effect was ingredient dependent.
Journal ArticleDOI
Feeding Oscillating Dietary Crude Protein Concentrations Increases Nitrogen Utilization in Growing Lambs and This Response Is Partly Attributable to Increased Urea Transfer to the Rumen
TL;DR: The data indicate that feeding oscillating dietary CP concentrations improves N retention partly by increasing urea recycling to the rumen when animals are fed low-CP diets, but the greater rates of urea transfer cannot be attributable to upregulation of UT-B.
Journal ArticleDOI
Control of wheat-induced lactic acidosis in sheep by thiopeptin and related antibiotics.
TL;DR: Thiope leptin and thiopeptin-like antibiotics, but not penicillin, appear to provide prophylactic treatment against lactic acidosis in sheep.
Journal ArticleDOI
Influence of ionophore addition to roughage and high-concentrate diets on portal blood flow and net nutrient flux in cattle
TL;DR: In this article, the effects of ionophore addition to roughage and high-concentrate diets on net nutrient flux across portal-drained viscera were investigated using cattle with chronic hepatic-portal and arterial catheters.
Journal ArticleDOI
Effects of glycerin on receiving performance and health status of beef steers and nutrient digestibility and rumen fermentation characteristics of growing steers
Kristin E Hales,K J Kraich,R. G. Bondurant,B E Meyer,M. K. Luebbe,M. S. Brown,N. A. Cole,James C. MacDonald,James C. MacDonald +8 more
TL;DR: The decrease in the A:P ratio as GLY increased in the diet, coupled with the linear decrease in DMI and improvement in G:F with GLY addition up to 5% of DM in place of roughage, implies that GLY is a viable dietary ingredient in growing and receiving 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.

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.
