复合L-氨基酸螯合钙对大鼠骨密度增加的影响

Effects on the Raising of Bone Density by Calcium Complex L-Amino Acid Chelate Compound in Weaning Rats

研究复合L-氨基酸螯合钙对SD大鼠骨密度的影响。将SD大鼠随机分成6组,分别喂养复合L-氨基酸螯合钙,"乐力"氨基酸螯合钙和低钙饲料,通过测量相应饲料喂养大鼠身长、体重、钙表现吸收率,股骨长度、质量、骨密度和股钙含量等指标,观察复合L-氨基酸螯合钙对SD大鼠骨密度的影响。结果表明:2种剂量的复合L-氨基酸螯合钙和"乐力"氨基酸螯合钙对大鼠的身长和体重、股骨质量、骨密度、钙含量和钙表观吸收率显著高于低钙饲料组(P<0.01),两种剂量水平的氨基酸螯合钙对大鼠骨密度、股骨钙含量和钙表观吸收率差异显著(P<0.01),复合L-氨基酸螯合钙具有增加大鼠骨密度的功能。

In order to study the effect of calcium complex L-amino acid chelate compound on the bone density of SD rat, SD rat were randomly divided into six groups and fed with feedstuffs containing calcium complex L-amino acid chelate compound, calcium amino acid chelate compound of ＂Osteoform＂ at different doses and feedstuff of low calcium. The length, weight of the rats, apparent absorptivity of calcium, length weight, density and calcium content of femoral bone were measured. The results showed that the length and weight of rats, weight, bone density, calcium content of femurs and apparent absorptivity of calcium were significantly increased in the calcium complex L-amino acid chelate compound and calcium amino acid chelate compound of ＂Osteoform＂ than in the low calcium feedstuff group （p〈0. 01）. The bone density, calcium content of the femurs and apparent absorptivity of calcium were significantly increased in the high calcium group than in the low calcium group （p〈0.01）. The calcium complex L-amino acid chelate compound was able to increase the bone density.
