微贮对秸秆饲料主要营养成分的影响

Effects of Microorganism Disposal on the Straw’s Main Nutrient Ingredients

选用微贮王菌种和EM菌种分别对秸秆样品进行处理,通过对秸秆样品的营养成分指标吸附水、粗蛋白、粗纤维、粗脂肪、粗灰分、钙、磷、无氮浸出物进行测定和计算,结果显示:粗蛋白增加了8%～30%,粗脂肪增加了7%～18%,粗纤维减少了20%～30%,粗灰分减少了18%～25%,钙、磷含量变化不显著。经方差分析表明秸秆微贮后与微贮前的营养成分比较差异极显著(P<0.05),但用两种菌种处理后的营养成分差异不显著(P>0.05)。说明秸秆微贮饲料的品质明显提高。

We used Wei zhuwang and EM to treat different straw samples. We determined the main nutrient ingredients （for example the moisture （original moisture, adsorptive mature）, crude protein, crude fiber, crude fat, crude ash, calcium, phosphorus）of these straw samples in laboratory. The results showed that the crude protein was increased 8% - 30%, the crude fat was increased7% - 18%, the crude fiber was reduced 20% - 30%, the crude ash was reduced 18% -25% , the calcium and the phosphorus was not remarkable changed, as compared with the controlled samples. By analysis of variance, the results indicated that the difference of straws＇ nutrient contents after micro-stored were great remarkable than the control groups （p〈0.05） , but there was not great remarkable difference between the treatment groups by the two different bacteria （p 〉 0.05） , and the straws treated with microorganisms were better than the control.
