As part of a larger experiment, 31 young bulls, divided into three groups, were given different
diets containing either C3 plants or a combination of C3 and C4 plant‐based feeds in three …

This study was aimed at determining whether isotopic ratio mass spectrometry (IRMS)
enables us to discriminate between lambs fed herbage or concentrate, both obtained from …

This study investigated the effect of substituting grass silage (C3 photosynthetic plant
product) with maize silage (C4 photosynthetic plant product) on the natural abundance …

The use of stable carbon isotopes as a means of studying energy flow is increasing in
ecology and paleoecology. However, secondary fractionation and turnover of stable …

The stable carbon and nitrogen isotopic composition of urine and milk samples from cattle
under different feeding regimes were analysed over a period of six months. The isotope …

The 13C: 12C ratio of C4 plants differs from that of C3 plants. In pasture samples or extrusa
samples containing tropical grasses (C4) and legumes (C3), the proportion of legumes …

Naturally occurring stable isotope ratios can be a powerful tool in studies of animal nutrition,
provided that the assumptions required for dietary reconstruction are validated by studies …

A pilot study was conducted to evaluate the suitability of stable isotope analysis for inferring
the feeding histories of cattle fed known feeds. Stable isotope ratios of carbon and nitrogen …

The aim of this study was to examine the variation in carbon and nitrogen stable isotope
ratios in cattle tissues from different provinces in China, and to investigate the correlations of …

The relation between the ratio of the natural 12C and 13C isotopes of carbon in the feed and
resultant faeces of animals was studied to develop a technique for estimating the proportion …
