Some effects of bone meal supplemented diet on bone and teeth of growing rats

Bone meal (containing 500 ppm F) was added to the diet of growing rats in an amount corresponding to that recommended ingested by children. Addition of bone meal did not influence body weight increment, or growth and ash content of bone and teeth. Fluoride in bone and teeth increased as compared to control animals, but the increase was 2-4 times less than if fluoride had been given as NaF. Analyses of feces disclosed significantly increased values of Ca and F in animals fed the bone meal supplemented diet, indicating low absorption of these minerals from bone meal.
