A comparison of stomach and faecal samples for diet analysis of grey kangaroos [Australia].
1988
Norbury G.L.
In an experiment with four captive eastern grey kangaroos, Macropus giganieus, microscopic analysis of both stomach contents and faeces did not reflect the ingested dry weight proportion of most plant species in a fed diet. However, close agreement was obtained by correcting for unidentifiable microscopic fragments of plants. This suggests that differential digestion may not be as important an artefact of microscopic diet analysis as previously reported. Provided corrections are made, faecal analysis may be as reliable as stomach content analysis for describing relative proportions of plant species in the diet of macropodids.
