Silage is good palatability, easy to digest, nutrient-rich, durable storage. Silage raw materials are abundant, and crop straws, weeds, weeds, sweet potato pods, etc. can all be used as silage materials. Silage is widely used in the feeding of ruminants and has been welcomed by farmers. The principle of silage Silage raw material requirements 1. The raw materials for sugar silage should have proper sugar content to ensure that lactic acid bacteria can multiply. After the increase of lactic acid, pH was adjusted to pH below 4.2. Sugar-rich feeds are most likely to be silage, such as red peony, marjoram, pumpkin, corn leaf poles, grasses, etc. Conversely, legumes containing more protein and less sugar content must be mixed with silage with high sugar content to ensure the silage quality. 2. The optimum moisture content for moisture is 65% to 75%. Simple judgment method: The silage raw material is crushed and squeezed by hand. The fingers have drops of water and do not drip, that is, suitable moisture content. Excessive moisture can be added or slightly drying, water shortage can be sprinkled water regulation. Silage production The production of silage requires continuous harvesting, transportation, short-term storage, cellar storage, step-up, and cell sealing, and the assault is completed at one time. Manpower, tools, silage equipment must be prepared in advance. 1. Timely harvesting When the water content is 65%~70%, the silage material without earth sand, hay, impurities and other foreign materials is of high quality. When the corn ribbon bar silage, the harvest time is the wax ripening period. When corn stalks are silage, more than two-thirds of the leaves are green and harvested in time after plucking the ear. The sorghum is in the milk ripening stage, the gramineous pasture is in the booting stage to the heading stage, the leguminous pasture is in the budding period to the initial stage of flowering, the sweet potato vine is in front of the frost or 1-2 days before the harvesting of the potato. 2. Timely transportation of chopped silage materials should be promptly transported to the silage site for harvesting after shredding and must not be piled up to avoid heating. The length of chopped raw material is generally 2~3cm, and the softer raw material is 3~5cm. 3. Adding nutrients To increase the nutritional value of silage, 5 kg of urea, 0.5 g of copper sulfate, 2 g of zinc sulfate, 1 g of cobalt oxide, 0.1 g of potassium iodide, and 500 g of sodium sulfate may be added per ton of silage material. 3 to 4 kg of urea phosphate, 0.5 L of lactic acid bacteria culture, or 450 g of lactic acid bacteria can be added per ton of raw materials. Mix thoroughly and dissolve in water. Spray evenly on the raw materials. 4. Quickly install the kiln sealing kiln In the process of modulating the silage, we must seize the time, shorten the exposure of raw materials in the air, reduce nutrient losses and prevent the contamination of bacteria. When loading, every 30cm thick should be compacted once, paying particular attention to the corners. Silage kilns not only need to be full, but also have to be 60 to 100 cm above the kiln mouth to seal the kiln. When covering the kiln, first cover a layer of straw or pasture, cover with a layer of plastic cloth, and then cover the soil 30 ~ 50cm into a bread-type. After sealing the kiln, it should be checked frequently and cracks or dents are found. Repairs must be made in time to prevent water and air leakage. The use of silage 1. After the kiln has been used for silage for 40 to 60 days, the fermentation can be started after the fermentation is completed. The area of ​​the open kiln should be based on the amount of feed used for the day and how much to eat. Pay attention to leveling out, do not dig out and pick it up. After the material is taken, the top of the kiln is covered with something to prevent rain and mud from entering. 2. The amount of feed fed to silage varies with the type of livestock, age, productivity, and silage material. Under normal circumstances, the daily feeding amount of dairy cows is 15~25kg. During the later period of pregnancy, the amount of feeding should be reduced and the feeding should be stopped 15 days before delivery. Serving cattle and fattening cattle, feeding 10 to 20 kg, 4 to 5 kg of sheep, and 6 to 8 kg of deer. 3. Feeding Precautions First, silage can not be used as a single diet for livestock, otherwise it is not conducive to the growth and development of livestock, should be used with carbohydrate-rich feed and hay, in order to increase the utilization of nitrogen in rumen microorganisms. Second, livestock has an adaptation process to silage and the dosage should be gradually increased from less. Third, the frozen silage will be fed to the room until it is melted. The silage that has deteriorated and deteriorated will be discarded to avoid causing poisoning or other diseases.

In silage, fresh silage materials are chopped into a silo, isolated from air, and fermented by lactic acid bacteria under anaerobic conditions to convert the sugar content of the raw materials to lactic acid. When the pH value of the lactic acid concentration reaches about 4.0, microbial activity can be suppressed, and nutrients in the raw materials are prevented from being further decomposed by the microorganisms, and nutrients in the raw materials are preserved to produce feeds rich in nutrients and having a special odor.
