| 摘 要： | 对大鼠进行正常饲料及低钙饲料中添加2%低聚木糖的喂养,喂养周期21d。测定大鼠钙摄入,粪钙、尿钙含量以及钙的吸收率。得出:低聚木糖能够有效提高大鼠对钙的吸收率,降低粪钙含量,并且,低聚木糖对低钙饲料组的影响比普通饲料组的影响大。在喂养1周之后低钙饲料+2%低聚木糖组的粪钙含量8.09mg,较相应对照组降低59.6%;普通饲料+2%低聚木糖组粪钙含量21.71mg,较相应对照组降低58.5%;低钙饲料+2%低聚木糖组的钙吸收率为94.84%;普通饲料+2%低聚木糖组的钙的表观吸收率为92.33%。另外,低聚木糖对尿钙影响不大。

| Abstract: | Feed on rats with normal diet,low calcium diet,normal diet(including XOS),low calcium diet(including XOS)for 21 days.Observed the calcium intake,the calcium concentration in faeces and urine,and surface absorption.Obtained:XOS can improve calcium absorption and reduce fecal calcium excretion in rats.And the effect of XOS in low calcium diet is huger than in normal calcium diet.After one week,calcium excretion in faeces reduced to 8.09mg and 21.71mg in low calcium diet(including XOS)and in normal diet(includ... |
