Abstract: | Concentrations of lactose in milk of Microtus montebelli were measured with the method using with the methylamine reaction. In this method, a small amount of sample (0.5 g) was sufficient for assay, and reproducibility and sensitivity were excellent. This method was very useful for measuring of lactose concentrations in experimental small animals. The average lactose concentration in milk of Microtus montebelli was 1.57g/100g, considerably low in comparison with the value of ICR mice (2.70g/100g). The low concentration of lactose in milk was considered to be one of metabolic characteristics of Microtus montebelli as a herbivorous animal. |
