切除７０日龄雌性大鼠双侧卵巢后，分别饲以低钙饲料（含Ｃａ０．０３３％）和标准饲料（含Ｃａ０．５２％），并与假手术组（ｓｈａｍ组）比较，于术后第２、４、６周末进行３次代谢试验。结果：低钙饲料组大鼠体重、股骨指数、钙吸收率和储留率、鼠体钙及钙利用率均明显低于其余组。标准饲料组大鼠体重及股骨指数与ｓｈａｍ组差异无显著性（Ｐ＞０．０５）。提示：低钙膳食严重影响去势雌鼠对钙的吸收和利用能力，妨碍大鼠生长及骨骼发育，补钙可在一定程度上消除去势大鼠钙代谢的障碍，有利于机体对钙的吸收利用
After ovariectomized 70-day-old female rats, they were fed with low-calcium diet (Ca0.033%) and standard diet (Ca0.52%), respectively, and compared with sham-operated group Metabolism tests were carried out on the 2nd, 4th and 6th weekend. Results: Body weight, femoral index, calcium absorption rate and retention rate, calcium and calcium utilization rate of rats in low calcium diet group were significantly lower than the other groups. There was no significant difference in body weight and femoral index between sham group and standard diet group (P> 0.05). Tip: low calcium diet seriously affect castration female calcium absorption and utilization ability, hinder the growth of rats and bone development, calcium to a certain extent, eliminate calcium disorders in ovariectomized rats, is conducive to the body of calcium Absorption and utilization
