钙是人体所必需的重要营养成份之一。各地营养调查情况表明,我国人民特别是儿童膳食中钙的来源和摄取量都还有些不足,因而钙质营养仍是我国营养学界所关切的重要向题。
The absorption and utilization of active ionic calcium powder in animal body was experimentally stu ied. The calcium powder was produced by the Dalian ionic calcium factory from the oyster shell which was abun- dant in the coastal area.The results indicated that the behaviors of active ionic calcium powder approximated to those of whole milk powder and calcium carbonate in rates of utilization of calcium in the feeds by the an imals,of absorption and retention in the calcium metabolism experiment,of retention of calcium in the femurs of the animals,etc.The active ionic calcium powder can therefore be used widely as a kind of nutritional addi- tives in food
