Effects of the rearing temperature on the temporal feeding pattern of the staggerer mutant mouse

The temporal feeding pattern of the staggerer mutant mouse was tested under two thermal rearing conditions, 28 degrees C and 22 degrees C, and compared to that of the normal mouse. At a temperature of 28 degrees C, the mutants were observed to eat more than the normal mice did although they showed a drastic body weight deficit. At 22 degrees C, this peculiarity was still observed, but with an altered feeding pattern, wherein the mutants ate as much during both the dark and light phases.
