Dry matter digestibility and apparent digestible and metabolizable energy of A. halimus were similar to those reported for other rodents consuming a vegetation diet. P. obesus reduces electrolyte intake by scraping off the outer layers of the leaves of A. halimus, particularly when dietary water content is low; in this study the rodents scraped off only 0.35-0.91% of the dry matter of the leaves, indicating that they had ample water. Water influx of P. obesus was 5.1-6.8 times that of other desert rodents, and water loss urine and feces was relatively high. Growing P. obesus consumed 64% of their body mass in fresh matter (13% in dry matter) each day. Consumption of A. halimus fulfils the energy and water needs of P. obesus. -from Authors
