[0002] Fermented feed uses microorganisms and complex enzymes as biological feed fermentation agents to convert part of the feed raw materials into microbial bacterial protein, microbial active probiotics, and complex enzyme preparations as a biological fermented feed. Fermented feed is fermented with straw. The product can not only make up for the amino acids that are easily lacking in conventional feed, but also can quickly convert the nutritional components of other roughage raw materials to enhance digestion, absorption and utilization. Its product advantages and functions, straw fermentation is a straw processing method for crop straw to improve its nutritional value, and has made positive contributions to the rational development of feed resources and the full solution of forage and feed problems, and has achieved huge economic and social benefits, so its market demand is huge.

[0003] In the actual straw fermentation process, the accumulation of straw will lead to uneven fermentation. The straw at the bottom of the pile will be over-fermented while the straw on the surface will not be fully fermented, which will affect the overall quality and fermentation time of the fermented feed.
