Abstract
Feeding a low Ca diet to growing dogs resulted in gross abnormalities of the long bones but had very little effect on the development of the permanent teeth. Three dogs were weaned and placed on Ca-deficient diets; 2 on a diet containing 0.027% Ca and 0.153% P, and the other on a diet with 0.196% Ca and 0427% P. The diets were adequate in other nutrient factors and the animals were continued on these diets throughout the period of the development of their permanent teeth. Gross skeletal abnormalities occurred, including bowing of the legs, spon- taneous fractures, etc., but the teeth showed little, if any, structural modification. The results indicate that the teeth are more resistant to the effects of the Ca deficiency during the period of rapid development than are the long bones.
