1. It is possible to maximize the maintenance of nutrients in green feed. Generally, the nutritional value of green feed is reduced by 30% to 50% after maturation and drying. However, in the silage process, due to anaerobic sealing, the oxidative decomposition of substances is weak, and the nutrient loss is only 3% - 10%, so that most of the nutrients are preserved, especially in the preservation of protein and vitamins (carotene) is far superior to other preservation methods. 2. Good palatability, high digestibility, fresh green feed, and silage to preserve water. Silage moisture content up to 70%. At the same time, due to the fermentation of microorganisms in the silage process, a large amount of lactic acid and aromatic substances are produced, which further enhances its palatability and digestibility. In addition, silage also has a good effect on improving the digestibility of other feeds in livestock diets. 3. Unbalanced supply of adjustable feedstuffs in Jinan Due to the short growth period of green fodder and the fast aging, it is greatly affected by the season and it is difficult to achieve a balanced supply throughout the year. Once the silage is made, it can be stored for a long period of time, and the storage period can be as long as 2 to 3 years or more. This can make up for the lack of time difference in the use of green feed and achieve a balanced supply of nutrients throughout the year. 4. Purifying feedstuffs and protecting environmental silage can kill pathogens and eggs in green feed and destroy the regenerative ability of weed seeds, thereby reducing the harm to livestock, poultry and crops. In addition, straw silage has greatly improved the phenomenon of straw burning for a long time, turning this resource into a waste, reducing the environmental pollution. Based on these characteristics, silage as a basic feed for beef cattle has been increasingly valued by countries. Anesthesia Medical Co., Ltd. , https://www.honestymed.com
