Maize straw silage fermentation technology

From July to October, it is the season when corn is harvested in different regions, and it is also the season for silage feed, a large harvest of corn stalks. Silage has a reputation of “canned grass”, succulent, savory and acid-smelling, high digestibility, and nutritious, and it is a superior feed for livestock such as cattle and sheep. Silage method is simple, low cost, as long as the slush material is shipped back in a short period of time, grasp the appropriate moisture, smashing and pressing, mixing Gem silage starter strains, compaction seal, without a lot of investment can be successful . Especially in autumn and winter seasons where green feed is lacking, silage is the best feed for cattle and sheep. The main technical points of corn straw fermentation silage are as follows:
1. Timely harvesting: Corn stalks should be harvested 7 days to 10 days before the grain is sufficiently ripened, and the stalks harvested in time. The yield and quality of the grains are hardly affected, and the nutritional value of the straw is greatly increased. Harvesting too late results in difficulty in compaction of silages, poor quality of fermentation, short shelf life, poor digestibility of various nutrients, and the need to add some green sweetpotato vines or other juicy grass to regulate water and nutrient content.
2. Silage Note: Clean up the area around the silo, place a good hoe machine at a suitable location, and prepare compaction tools to prevent the mud from flowing into the silo. Silage corn stalk cutting length is generally about 2 to 3 cm is appropriate. If it is too short, it will lead to reduction of effective fiber that stimulates the chewing of cattle, which will affect its digestion and absorption. If it is too long, it will affect the compaction density of the pits and cause the quality of the silage to decline or deteriorate. The size of the silo should be determined according to the speed of the farmer (at least 15 cm per day). Fill the silage with fast loading and tight compaction (when 15 cm to 20 cm thick, squeeze with a compaction tool).
3, the use of microbial fermentation agent to improve the quality of silage: The principle is to add fast-growing pure lactic acid bacteria to achieve control of fermentation, improve the success rate of silage, and then produce high-quality silage. In silage, a certain proportion of Jinbao silage starter (5 tons of Jinbao starter for silage materials, one kilogram) was added. The functional microorganisms in Ginba silage starter digest and decompose the plant cell walls to produce soluble sugars. Lactic acid bacteria use these sugars to ferment, thereby reducing the silage pH, promoting silage fermentation, improving fermentation quality, and reducing dry matter loss. The digestibility of animals and the degree of silage utilization. And some functional microbial populations in silage fermentation have a strong ability to inhibit fungal activity, which can effectively inhibit the production of harmful bacteria and prevent silage mildew. Silage after fermentation also increases bacterial protein, and it is more suitable for palatability, nutrition, and digestibility, which can effectively reduce the total cost of feeding.
4. Management after opening the pit: Take out enough silage for feeding every day to keep the receiving surface clean and reduce the loss. After taking the material, seal it quickly to reduce air retention and prevent aerobic deterioration.
