Rumen bacterial urease requirement for nickel.
TL;DR: Two collection periods with lambs fed a diet in which all the nitrogen was supplied as preformed protein (casein) indicated that ruminal urease activity was much lower in lambs feeding the low nickel diet, while 1% urea was added to the basal diet.

Enzyme use in kibble diets formulated with wheat bran for dogs: effects on processing and digestibility.
F. C. Sá,Ricardo Souza Vasconcellos,Márcio Antônio Brunetto,F. O. R. Filho,Márcia de Oliveira Sampaio Gomes,Aulus Cavalieri Carciofi +5 more
TL;DR: The enzyme addition did not result in improved digestibility of a diet high in non-starch polysaccharides; however, only ATTD was measured and nutrient fermentation in the large intestine may have interfered with the results obtained.
Journal ArticleDOI
Efeito da adição de níveis crescentes de polpa cítrica sobre a qualidade fermentativa e o valor nutritivo da silagem de capim-elefante
Paulo Henrique Mazza Rodrigues,Laura Maria Oliveira Borgatti,Rériton Weldert Gomes,Roberta Passini,Paula Marques Meyer +4 more
TL;DR: In this article, the efeitos da adicao de polpa citrica peletizada sobre a qualidade fermentativa e o valor nutritivo da silagem de capim-elefante were investigated.
Journal ArticleDOI
Dietary alteration of particle breakdown and passage from the rumen in lactating dairy cattle.
S.T. Woodford,Michael R. Murphy +1 more
TL;DR: Data suggested that small particle passage may be more closely related to ruminal fluid outflow and DM intake than large particle breakdown rate.
Journal ArticleDOI
Effects of supplemental fat and protein source on ruminal fermentation and nutrient flow to the duodenum in dairy cows.
TL;DR: Four lactating Holstein cows, fitted with ruminal and T-type duodenal cannulas, were used in a 4 x 4 Latin square design for four periods and yields of milk, milk protein, and SNF were increased by added fat and by high quality protein.

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.
