Corn silage is a kind of feed with good palatability, high digestibility and nutrient-rich feed, which guarantees a balanced supply throughout the year, through the anaerobic fermentation and chemical action of minced and fresh corn stalks under closed anoxic conditions. Effective measures for livestock feed. By using the silage method, the corn stalks that remain green or green after autumn harvest can be stored for a long period of time, and the nutrients can be well preserved, and the texture can be softened and scented. This can increase the appetite of cattle and sheep and solve the forage of winter and spring. insufficient. At the same time, the production of silage will save half the area of ​​land compared to stacking the same amount of hay, and it will also help prevent fire, rain, mildew, and eliminate crop pests on the straw. Compared with hay, corn silage has the following advantages:
1. Nutrient-enriched silage can reduce the loss of nutrients and improve feed utilization. Drying hay generally loses 20% to 30% of nutrients, sometimes up to 40%, while silage only loses 3% to 10% of nutrients, and is particularly effective in preserving vitamins. In addition, silage can also eliminate many parasites (such as corn borer, borers) and harmful bacteria that are carried by raw materials. It is determined that the nutritional value of the whole plant corn silage produced on the same unit area of ​​cultivated land is 30%-50% higher than the nutritional value of the corn grain plus dried corn stalk produced.
2. Good palatability The silage is soft and juicy, smells sweet and sweet, and palatability is good; especially in the dry season, livestock can eat green feed and naturally increase feed intake. At the same time, it also promotes the secretion of digestive glands and also has a good effect on improving the digestion of other feeds in livestock diets. Experiments have shown that the digestibility of silage has been improved compared with silage made from the same kind of grass and hay.
3. Contributing to the increase of milk production A large number of feeding experiments have shown that feeding silage can increase milk production by 10% to 20% for milk producing animals, and the increase is influenced by the nutrient content of silage materials and quality after silage.
4. Making Simple Silage is one of the most effective and inexpensive ways to keep green feed nutrients. Silage raw materials have a wide range of sources. Various green and green fodder, green crop stalks, melon and canola meal, high-moisture grains, and bad residue can all be used to make silage. Silage production is not affected by seasons and weather; the production process is simple. Less labor input; compared with preserving hay, making silage has a small footprint and is easy to store.
5. Preservation time The silage raw materials are usually fed for 40 days to 50 days after being confined. The silage that is properly stored can be stored for several years.
