Prediction of Elemental Content in the Old-Field Mouse

Donald W. Kaufman and Glennis A. Kaufman



Elemental composition of laboratory-raised old-field mice was examined from birth to 6 weeks of age.  Correlations between live weight and live-weight concentrations of 14 elements and between dry weight and dry-weight concentrations of these elements were examined, as were correlations for data transformed to natural logarithms.  Equations for predicting the amounts of these elements present from both live-weight and dry-weight values were calculated.  The best estimate of elemental content for live 0- to 6-wee-old animals came from the prediction of the natural logarithm of the amount of each element computed from the natural logarithm of the live weight.  For live trappable-size mice (3 to 6 weeks of age), the average live-weight concentration was the best estimator of elemental content.  Elemental content from dry weight for both 0- to 6- and 3- to 6-week-old mice should be estimated from regression equations relating the logarithm of the amount of each element to the logarithm of dry weight.
