Abstract
The nitrogen requirements of some female euros (Macropus robustus) were
determined by means of nitrogen balance feeding trials. The average minimum dietary
nitrogen requirement for the maintenance of nitrogen equilibrium was 1.99 g/day
or 309 mg/day per kgW*0.73. The metabolic faecal nitrogen output of the euros, determined
indirectly, was estimated to be 0.27 g/100 g dry matter intake.
The minimum digestible nitrogen requirements of the euros were 160 mg/day per
kgW*0.73, equivalent to approximately 1 g digestible nitrogen per day. The minimum
urinary nitrogen excretion of the euros, at dietary nitrogen intakes of approximately
1 g/day, was an average of 34 mg/day per kgW*0.73.
Comparison of the results obtained with data for eutherian species reported in the
literature indicates that the nitrogen requirements and urinary nitrogen excretion of this
species is markedly less than that of eutherian species. The results are briefly discussed
in relation to survival of the euro in the arid environment of the Pilbara district of Western
Australia.
