摘　　要：将１８０只１９周龄健康伊莎笼养蛋鸡随机均分为对照Ａ和低钙Ｂ、Ｃ、Ｄ四组，分别饲喂钙含量为３．５５％、２．５０％、２．０５％、１．２７％的日粮。不同时间进行骨骼病理组织学检查和活体骨矿含量（ＢＭＣ）测定。结论：低钙日粮诱发的蛋鸡骨质疏松除具有典型的骨质疏松病理变化外，骨矿含量也明显减少。：180 19－week old age ISA cage layers were equally divided into control group（A）、low calcium B，C and D at random and fed separately with 3．55％，2．50％，2．05％ and 1．27％ calcium in their dietary．Pathological examination of bone and measurement in vivo of bone mineral content （BMC）were carried out at certain interval．In conclusion，the cage layer bone loss induced by low calcium dietary was characteristic of osteoporotic pathological change and significant decrease in BMC．
