Intestinal glucose absorption but not endogenous glucose production differs between colostrum- and formula-fed neonatal calves.

J Steinhoff-Wagner, Solvig Goers, +4 authors Harald M Hammon
The Journal of nutrition
2011

Glucose supply markedly changes during the transition to extrauterine life. In this study, we investigated diet effects on glucose metabolism in neonatal calves. Calves were fed colostrum (C; n = 7)… (More)

Gas chromatography/combustion/isotope ratio mass spectrometric comparison of N-acetyl- and N-pivaloyl amino acid esters to measure 15N isotopic abundances in physiological samples: a pilot study on…

Cornelia C. Metges, Klaus Jürgen Petzke, Ulf Hennig
Journal of mass spectrometry : JMS
1996

There is evidence that in animals and also in humans, non-specific nitrogen is used for de novo synthesis of indispensable amino acids by the microflora of the gastro-intestinal tract. Gas… (More)

Metabolic changes and net portal flux in dairy cows fed a ration containing rumen-protected fat as compared to a control diet.

Harald M Hammon, Cornelia C. Metges, +6 authors Hélène Lapierre
Journal of dairy science
2008

Feeding rumen-protected fat (RPF) is an alternative to increase energy density of the diet and therefore energy intake in dairy cows. To investigate metabolic and endocrine changes in dairy cows fed… (More)

Limited and excess dietary protein during gestation affects growth and compositional traits in gilts and impairs offspring fetal growth.

Charlotte Rehfeldt, Iris S. Lang, +9 authors Cornelia C. Metges
Journal of animal science
2011

The aim of this study was to investigate whether dietary protein intake during gestation less than or greater than recommendations affects gilts growth and body composition, gestation outcome, and… (More)

Carbon and nitrogen stable isotopic composition of hair protein and amino acids can be used as biomarkers for animal-derived dietary protein intake in humans.

Klaus Jürgen Petzke, H. Böing, Susanne Klaus, Cornelia C. Metges
The Journal of nutrition
2005

The stable nitrogen (15N) and carbon (13C) isotopic composition of tissues reflects the isotopic pattern of food sources. We investigated whether the isotopic composition of human hair can be used as… (More)

Measurement of 15N/14N isotopic composition in individual plasma free amino acids of human adults at natural abundance by gas chromatography-combustion isotope ratio mass spectrometry.

Cornelia C. Metges, Klaus Jürgen Petzke
Analytical biochemistry
1997

We describe a high-precision methodology to determine the 15N/14N isotopic composition of 13 plasma free amino acids out of 500 microliters plasma, measured as N-pivaloyl-i-propyl amino acid esters… (More)

Medium- and long-chain triglycerides labeled with 13C: a comparison of oxidation after oral or parenteral administration in humans.

Cornelia C. Metges, Gunther Wolfram
The Journal of nutrition
1991

The special physical properties of medium-chain triglycerides (MCT) result in some substantial differences in their metabolism compared to that of long-chain triglycerides (LCT). Administering MCT is… (More)

Ileal losses of nitrogen and amino acids in humans and their importance to the assessment of amino acid requirements.

Claire Gaudichon, C. Ulrike Bos, +7 authors Cornelia C. Metges
Gastroenterology
2002

BACKGROUND & AIMS Irreversible amino acid losses at the human ileum are not taken into account when tracer-derived amino acid requirements are calculated because the data available are scarce. We… (More)

Differences in milk production, glucose metabolism, and carcass composition of 2 Charolais x Holstein F2 families derived from reciprocal paternal and maternal grandsire crosses.

Harald M Hammon, Cornelia C. Metges, +7 authors Christa Kuehn
Journal of dairy science
2010

Two F(2) Charolais x German Holstein families comprising full and half sibs share identical but reciprocal paternal and maternal Charolais grandfathers differ in milk production. We hypothesized that… (More)

Postprandial kinetics of dietary amino acids are the main determinant of their metabolism after soy or milk protein ingestion in humans.

C. Ulrike Bos, Cornelia C. Metges, +6 authors Daniel Tomé
The Journal of nutrition
2003

Soy proteins have been shown to result in lower postprandial nitrogen retention than milk proteins, but the mechanisms underlying these differences have not been elucidated. To investigate this… (More)
