Glucose metabolism in a kangaroo (Macropus robustus erubescens) and a similar size eutherian herbivore, the feral goat.
1. Glucose pool size, space, entry rate, and turnover time were estimated from the specific radioactivity vs time curves of [3H] and [14C]glucose administered as a single injection in the euro (Macropus robustus erubescens) and the sympatric feral goat (Capra hircus). 2. Digestible energy intake was greater (P < 0.05 +/- SE) in the goat than in the euro (798 +/- 64 vs 624 +/- 31 kJ/kg0.75 x day). 3. However, there were no significant differences between the two species in parameters of glucose metabolism. 4. The use of an implantable osmotic infusion pump to deliver isotropic glucose showed promise as a means of avoiding the stress involved with the single injection technique.
