At present, the world's advanced silage technology is coated silage technology. After shredding the harvested corn straw, fresh forage, etc., the strapping machine is compacted and bundled with high density, then wrapped in silage plastic tensile film, The grass bundle is in an optimal sealed fermentation environment. Under anaerobic conditions, the biochemical process of natural fermentation of lactic acid type was finally completed after 3-6 weeks. The crude protein content of the finished product increased, the ph value decreased, the total soluble sugar content increased, and the livestock feeding rate reached 100%.
As the world's most advanced silage technology packaging products, forage film in Europe, the United States, Australia and other countries and regions have been widely used and has more than more than 10 years of mature use experience.
