Body temperature of C57BL/6J mice with age.
On the basis of a study of rectal temperature in a group of 180, C57BL/6J male mice, ranging in age from 3 months to 30 months, the following conclusions were drawn: 1) The positive correlation between body weight and body temperature typical for rodents was found only for young adults of the C57BL/6J strain; 2) body temperature of male C57BL/6J did not appear to decline until about 23.5 months, after which there was a significant negative correlation (r = -0.53) between age and temperature.
