牛羊预混料碘元素添加量对产品质量的影响

The influence of the content of iodide micro-element in compound premix for cattle and sheep on product quality

采用硫氰酸铁—亚硝酸催化法测定 1 %牛羊复合预混料中微量元素碘含量。结果表明 :实际投入量KI为 37 1 9g/t,抽样保证概率为 99%以上 ,KI的实际投入量比配方设计值多8 1 3g/t。如按配方设计值KI为 2 9 0 6g/t投料 ,抽样保证概率仅为 5 5 %。

Using the method of Fe(SCN) HNO 2 catalyze,the 1% content of iodide micro element in compound premix for cattle and sheep was menstruated.The results were showed that the sample statistical probability was 99% more under the reality KI to put into compound premix was 37 19g/t,which reality KI was 8 13g/t more than the design value for prescription.If it was conducted that design value KI for prescription was 29 06g/t,the sample statistical probability was only 55%.
