Study on Feed Processing and Application of Renewable Plant Humulus Scandens

In order to study the feed processing and development technology of the renewable plant Humulus scandens, Humulus scandens were collected, dried and comminuted at the stage of leaf unfolding, flower opening, flower blooming and yellow withering, and processed into direct raw material group, silage natural fermentation group and silage plus bacteria fermentation group. The contents of main nutrients and total flavonoids in Humulus scandens feed were determined and compared. The microbial quantity and fermentation quality of Humulus scandens in withered and yellow period in silage natural fermentation group and silage plus bacteria fermentation group were detected. The results showed that there was no significant change in calcium and phosphorus content in the three groups. The other nutrients in silage natural fermentation group and silage plus bacteria fermentation group were slightly lower than those in direct raw material group. The content of total flavonoids in silage plus bacteria fermentation group was significantly higher than that in other groups. In terms of fermentation quality and microbial quantity, the fermentation of silage natural fermentation group was not obvious, the pH value was on the high side, the fermentation of silage plus bacteria group was obvious, and the quality was also higher. In conclusion, if Humulus scandens is directly used as feedstuff, the best collection time is the blooming period of flowers. If silage and lactobacillus fermentation are used, the value of feedstuff is the highest, but the value of silage natural fermentation is the lowest, so it is not recommended to choose.
