Objective   To observe the effects of calcium taurinate on the content of serum calcium, iron and phospate and the weight of immune organs and brain of rats.

  Methods   The rats were assigned to four groups, low calcium diet group calcium taurinate group, calcium carbonate group and calcium lactate group.After 4 weeks, the countent of serum calcium, iron and phosphate were tested, the weight of rats, spleen, thymus and brain were weighted.

  Results   The content of serum calcium, iron and phosphate of calcium taurinate group were obviously different from calcium lactate group(P < 0.05), and serum phosphate content of calcium taurinate group was also different remarkably from that of calcium carbonate group(P < 0.05).Serum calcium content in calcium taurinate group was the highest among three groups, and serum iron content was the lowest.Every group showed high serum calcium content and decreased irom and phosphate levels.The weight of brain and spleen in calcium taurinate group were obviously heavier than those in other two groups(P < 0.05), and calcium carbonate group were the lightest.The weight of thymus in four groups had no distinct difference.

  Conclusion   Calcium taurinate can obviously increase the content of serum calcium, and different calcium agents affect absorption of phosphate and iron.Calcium taurinate not only has the effect of supplying calcium, but also can improve immune ability and promote brain development.
