Abstract:

In order to detect the essential amino acid of the forage. In this study, Lys, Try, Pro and reducing sugar of the CHE feed were extracted and the assay of their variation were carried out. The results showed that the maximum of Lys was 1.82 μg/g; and the maximum of Try was 309.26 μg/g; and the maximum of Pro was 428.61 μg/g. At the same time, the content of reducing sugar was stabilized at 3.03%. Fermentation period was optimized between 108 h. At this time, the content of amino acid WAS maximum, and the content of reducing sugar was stabilized.
