This study is to find out how the 4 types of calcium salt such as calcium carbonate, calcium phosphate, calcium lactate and calcium citrate in soy protein diet, the vegetable protein source, affect the calcium utilization in the body. To do so, calcium, phosphate and creatinine concentration and ALP activity in blood as well as the content of calcium and ash, the length, weight, strength, and the calcium utilization in the bone were measured. Four groups of Sprague-Dawley male rats with the weight of around 180g were fed for 3 weeks with the experimental diet. Each group was fed with the isolated soy protein containing 14% of the diet and the above mentioned 4 types of calcium salt as the calcium source. The results are as follows;
1. There were no differences of the feed intake, weight gain, and feed efficiency among groups.
2. ALP activity in blood was sinificantly high in calcium lactate group(P＜0.05), but there were no differences of concentration of calcium, phosphates, and creatinine in blood among groups.
3. The weight, calcium content, calcium ratio in ash and the strength of bone were low when calcium lactate was provided(P＜0.05).
4. The content of calcium in the liver was high in calcium lactate group and calcium citrate group(P＜0.05).
5. The exceretion of feces was low in calcium lactate group(P＜0.05) and the excretion of urine was also relatively low. In addition, the ratio of absorption and the retention of calcium were high(P＜0.05).
In summary, out of four types of calcium salt such as calcium carbontate, calcium phosphate, calcium lactate and calcium citrate when calcium lactate was provided the ALP activity in blood was high and the weight, calcium content, calcium ratio in ash and the strength of bone were low. In calcium utilization, the ratio of absorption and retention of calcium were high, however it has lower effect than 3 other calcium types in improving weight, the content of calcium and the strength of bone.
