Description

The effects of the amount of calcium intake during pregnancy on the contents of calcium, phosphorus and magnesium of the pregnant rats were investigated.<br>Just before the delivery, on 22nd day of gestation, the mother rats were killed and analysed, after their fetuses were removed.<br>From the analytical data of 20 rats of 4 groups we found that, average percentages of calcium, phosphorus and magnesium of rats of C group fed with the high calcium diet from the beginning were higher than those of the other groups, and also it was found that the percentages of minerals in the bodies were not in parallel with the amount of calcium intake.<br>It seemed that, in pregnancy, high calcium feeding in the early or the middle period is better on calcium retention and utilization than other ways.
