Recently, in Linze County, Gansu Province, the technology is to send the smashed straw from the straw expansion processing machine to the machine, and then send the packaged feed. In just a few minutes, the dry yellow straw can be cut. Crushed, mixed water, puffed, added lactic acid bacteria, packaging, coating and other processes. Through the puffing and processing technology, the corn stalk has changed from a hard roughage to a bio-feed that is easily digested and absorbed, and the traits have undergone tremendous changes, realizing a “gorgeous turn” from discarded straw to biological feed.

According to relevant experts, straw-expanded biological feed as a microbial storage feed has higher nutritional value than dry storage, and has lower price than silage, and is the most cost-effective production, quality and income-increasing feed. This technology can not only produce certain social, economic and ecological benefits, but also improve soil and reduce environmental pollution. It is a good measure to benefit the country and the people.
