[Composition of milk and electrophoretic analysis of milk casein in herbivorous voles (Microtus montebelli)].

Milk samples were collected from herbivorous voles (Microtus montebelli) and their compositions were analyzed. Total solids, fat, protein and ash concentrations of vole's milk were very higher than those of cow's milk. The lactose concentration was very lower than that of milk of cow or mouse. The electrophoretic patterns of milk casein of vole were different markedly from those of bovine, but resembled to those of mouse.
