【摘要】：旨在探讨钼镉联合诱导对鸭组织器官中微量元素含量的影响。选取120羽11日龄"江南2号"麻鸭随机分成对照组、低钼组、高钼组、镉组、低钼镉组和高钼镉组,每组20羽,以(NH_4)_6Mo_7O_(24)·4H_2O和3CdSO_4·8H_2O作为钼源和镉源,对照组饲喂基础日粮,其余各组分别在每千克基础日粮中添加Mo 15 mg、Mo 100 mg、Cd 4 mg、Mo15mg+Cd 4mg和Mo 100mg+Cd 4mg,试验期120d。于试验60、120d每组随机选10羽鸭剖杀,采集相应组织器官,用原子吸收分光光度法测定心脏、肺脏、大脑、气管、肌肉中Mo、Cd、Cu、Fe、Zn、Se含量。结果表明:钼镉及其联合诱导使各组织器官中Mo、Cd含量升高(P0.01),Cu、Fe、Zn、Se含量降低(P0.05或P0.01),且钼镉联合组比单独组下降更明显,钼镉呈协同作用。
[Abstract]:The aim of this study was to investigate the effect of molybdenum and cadmium combined induction on the content of trace elements in duck tissues and organs. 120 11-day-old "Jiangnan No.2" ducks were randomly divided into control group, low molybdenum group, high molybdenum group, cadmium group, low molybdenum cadmium group and high molybdenum cadmium group with 20 in each group. (NH_4) 6Mo7O24 4H_2O and 3CdSO_4 8H_2O were used as molybdenum source and cadmium source. The other groups were fed with Mo 15 mg,Mo 100 mg,Cd 4 mg,Mo15mg Cd 4mg and Mo 100mg Cd 4 mg per kg basal diet for 120 days. Ten ducks of each group were selected randomly for 60120 days in the experiment. The Mo,Cd,Cu,Fe,Zn,Se contents in heart, lung, brain, trachea and muscle were measured by atomic absorption spectrophotometry. The results showed that the content of Mo,Cd in tissues and organs increased (P0.01) and decreased (P0.05 or P0.01) after molybdenum and cadmium and its combined induction, and the content of Mo and CD in the combined group was more obvious than that in the single group, and there was a synergistic effect of Mo and CD.
