【摘要】：粗蛋白質(zhì)是飼料的重要指標(biāo),也是飼料產(chǎn)品的必檢指標(biāo)。本試驗(yàn)選擇采用傳統(tǒng)的半微量定氮法和兩種不同型號(hào)的全自動(dòng)凱氏定氮儀法對(duì)10種蛋白飼料原料中的粗蛋白質(zhì)含量進(jìn)行檢測(cè),分析不同方法的準(zhǔn)確度,為飼料質(zhì)量檢測(cè)分析檢測(cè)技術(shù)提供參考。試驗(yàn)結(jié)果表明,全自動(dòng)凱氏定氮儀更適合大批量樣品的檢測(cè),而且檢測(cè)精度更高。
[Abstract]:Crude protein is not only an important index of feed, but also a necessary index of forage products. In this experiment, the traditional semi-trace nitrogen determination method and two different types of automatic Kjeldahl nitrogen determination instrument were used to detect the crude protein content in 10 kinds of protein feed raw materials, and the accuracy of different methods was analyzed. It provides a reference for the detection and analysis of feed quality. The test results show that the automatic Kjeldahl nitrogen determination instrument is more suitable for mass sample detection and has higher detection accuracy.
