| 摘 要： | 利用植酸酶分别对6种植物性原料（豆粕、棉粕、次粉、啤酒糟、米糠、菜粕）进行处理。研究在不同浓度的植酸酶作用下，6种植物性原料中有机磷的转化情况。研究发现，植酸酶能显著降低6种原料中的有机磷含量（P〈0．05），提高无机磷的含量。通过对磷当量的测定，本实验中用1000U／kg植酸酶处理最为经济有效。

| Abstract: | The study was aimed at assessing effects of microbial phytase treatment on the organophosphorus content in six plant ingredients （ soybean meal, cotton seed meal, wheat - middlings, beer grains, rice bran and rapeseed meal ）. Graded levels of microbial phytase were dissolved and separately mixed with soybean meal, cotton seed meal, beer grains, rapeseed meal, wheat - middlings and rice bran. Studies found that the organophosphorus contents de- creased significantly （ P 〈 0.05 ） while the inorganic phosphorus levels increased along with the increasing doses of phytase. According to the analysis of phosphorus equivalency, the dose of 1000U/kg was most costefficient. |
