Making silage technical points

Keeping raw materials containing proper amounts of water and sugar, chopping, compacting, and sealing are some basic conditions for good silage. Moisture: The proper moisture content of the silage is generally 70%-75%. After the raw material is shredded and held in the hand, the hand feels moist, but it is not suitable for dripping. The minimum is not less than 55%. When legumes are used as raw materials, the water content is preferably 60%-70%. Insufficient water can be sprayed with water, and high water content can be mixed with hay powder, bran, etc. Sugar: The lowest content of soluble sugar in raw materials is 2%. When the sugar content is insufficient, the green plant mixed silage with a high sugar content may be incorporated, or the sugar beet strip may be added to the silage material. Or add appropriate amounts of bran, starch, etc. Temperature: The optimum temperature is 20°C and the highest temperature is 37°C. Shredding: The length of raw materials should generally be within 2 centimeters, which is convenient for compaction and exhaust. Generally rough raw materials should be cut properly. The soft raw materials can be appropriately longer. Feeding cattle and sheep can be lengthened as appropriate. Feeding pigs can be shortened. After the silage is chopped, it is required to be loaded on the same day. Packing cellar compaction: When the raw materials are stored in the cellar, they must be cut and stored while being solid. Small-scale operations can be stepped on layers, such as a large silo, tractor compaction can be used. Pay special attention to the corners without any gaps. After the raw materials are filled, they must be more than 50 cm above the ground to ensure that they do not leak or seep into the rain after sinking. Sealing: After the raw materials are filled and compacted, cover with a layer of plastic film, tightly sealed, and cover about 50 cm. After 2-3 days of capping, it is necessary to observe at any time. It is found that the sinking of raw materials should be filled in the subsidence. After 30-45 days, the silage can be successfully modulated.
