摘要
以硼酸的形式在鸡的饮水中添加不同质量浓度的硼 ,添加量 ( ρ)分别为 0、 1 0 0、 2 0 0、40 0mg/L ,比较其增重、成活率和料肉比 ,观察对鸡生长的影响。结果表明 ,饮水硼含量 ( ρ)在1 0 0mg/L时 ,有提高雏鸡成活率和饲料转化率的作用 ;而当饮水硼含量 ( ρ)大于或等于 2 0 0mg/L时 ,对雏鸡的生长有不利的影响。
Several different concentration(0 mg/L,100 mg/L,200 mg/L,400 mg/L)of boron have been added in the form of boron acid into drinking water of the chicken.The liveweight increase rate,food conversion rate and effects of boron for the chicken growth have been observed.The result showed while the concentration of boron at 100 mg/L in water,there were advanced for the survival rate and conversion rate,but there were badly influences when the concentration of boron is or more than 200 mg/L.It has been provided a lot of valuable date for studies of boron.
