Prediction of Elemental Content in the Old-Field Mouse
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.
