Energy metabolism and nitrogen balance in the fat jird (Meriones crassus) and the Levant mole (Microtus guentheri)

Abstract

Energy intake of fat jird when fed on alfalfa hay, amounted to 77% of that recorded for the Levant mole, whereas energy digestibility was similar in the 2 species. Metabolic rate (O2 consumption) in the fat jird was 60% that of the Levant vole. When fed Panicum grass, the gross and digestible energy intake and metabolic rate dropped only in the Levant vole. Low energy metabolism, together with a high capacity for digesting dry plant feed and low nitrogen requirements enables fat jird to cope with food shortage. Voles were unable to adjust to a low quality diet. -from Authors
