不同地区大豆及其副产品微量元素的分析

Analysis of trace elements in soybean and its by-products from different regions

文章分别对不同地区大豆及其副产品饲料原料中的微量元素进行对比。研究供搜集了190份来自全国不同地区的玉米及其副产品样品。结果表明,大豆及其副产品饲料原料中铜、铁、锰、锌4种微量元素的平均含量分别为5.23、137.38、7.75、42.63mg/kg。不同大豆副产品饲料原料的铜、铁、锰、锌4种微量元素含量差异较大,差异系数分别为50%、17%、24%、27%。总体上看,不同地区大豆及其副产品饲料原料中微量元素含量差异较大。本研究结果对饲料营养配方优化,尤其是微量元素的合理分配有极为重要的参考价值。

In this paper,the trace elements in soybean and its by-product feed materials in different regions were compared and analyzed. This study is to collect 190 samples of maize and its by-products from different regions in China. The results showed that the average contents of copper,iron,manganese and zinc in soybean and its by-product feed materials were 5.23,137.38,7.75and 42.63 mg/kg,respectively. The contents of copper,iron,manganese and zinc in feed materials of different soybean by-products were significantly different,and the difference coefficients were 50%,17%,24% and 27% respectively. In general,the content of trace elements in soybean and its by-product feed materials varies greatly in different regions. The results of this study have very important reference value for the optimization of feed nutrition formula,especially the reasonable distribution of trace elements.
