Effect of Ovariectomy on Basal Metabolic Rate of the Albino Rat

Conclusions

Following the removal of the ovaries in young rats (26th day of age) the animals will gain weight much faster than the control rats for the first few weeks and will remain heavier at least up to 800 days of age. During the growing period when the rate of growth of the ovariectomized rats is significantly greater than the controls the metabolic rate is significantly higher in the former than the latter. The metabolic rate of the normal and ovariectomized rat will be higher at 800 days of age than at 200 days of age, but less at either of these ages than at 90-105 days when growth is taking place most rapidly.
