title: Protein turnover in two kangaroo sub-species (Macropus robustus robustus and M. r. erubescens) from divergent habitats and the sympatric feral goat (Capra hircus).
abstract: 1. Whole-body protein turnover was measured by a single-injection [15N]glycine method in the euro (Macropus robustus erubescens), wallaroo (M. r. robustus) and goat (Capra hircus). 2. Dietary nitrogen (N) intake was greater (P < 0.05) in the goat (1.17 g N/kg 0.75 x day) than in the kangaroo sub-species and greater (P < 0.05) in the wallaroo (1.07 g N/kg 0.75 x day) than in the euro (0.93 g N/kg 0.75 x day). similar (0.29-0.34 g N/kg 0.75 x day) among the species. 3. Crude protein (CP) turnover was similar in the euro (14.8 g CP/kg 0.75 x day) and goat (13.8 g CP/kg 0.75 x day) and less (P < 0.05) in the wallaroo (10.4 g CP/kg 0.75 x day).
