【摘要】 本试验采用了０．２％、０．４％、０．６％、０．８％四种不同浓度的硫酸钠（Ｎａ＿２ＳＯ＿４）给１０天龄的肉用鸡连续自由饮水７天后，再正常饲养７天，测定其增重、饲料转化率、肉料比等各项生产性能指标。结果表明：各试验组之间、试验组与对照组之间均无显沓性差异（Ｐ＞０．０５）。临床上观察，０．８％Ｎａ＿２ＳＯ＿４组粪便较其他试验组和对照组稀，但色泽无明显改变，而０．２％、０．４％、０．６％Ｎａ＿２ＳＯ＿４组与对照组之间无明显变化。各组鸡在整个试验过程中精神状态均良好，米发现不同浓度的Ｎａ＿２ＳＯ＿４饮水对鸡的生长发育有任何不良影响。更多还原

【Abstract】 In this trial,let the 10 day broiler;freely drink the 0.2%、0.4%、0.6%and 0.8%concentration of Na₂SO₄ respectively for seven days,rear them normally for seven days again,then evaluateseveral targets of Derformance about the increasing weight, feed conversion rate and meat/feed etc.The result show that there is no significant difference among the test group and between the test groupand the control group（P>0.05） In clinical examination,the faeces of the 0.8%Na₂SO₄ group aremore watery than others of the test and control group, but the color and lustre have no significant change, There is no significant change between the 0.2%,0.4% ,0.6% concentration of Na₂SO₄groups and the control group. During the trial the state of chickens in each group is good.No affect was found to the chickens’ growth in the drinking of different concentration of Na₂SO₄.更多还原
