Four functions of silage fermentation feed Silage fermentation has obvious advantages over direct drying and feeding of straw:
1. Preservation of nutrients: In the course of storage, feed must have a certain amount of nutrient losses. However, the method of storage is different, and the type and amount of nutrient losses are also different. For example, during the haying process, the loss of nutrients is 30-40%. However, silage is fermented with silage starter. Since there is no influence of sunlight and rain, the loss of nutrients is less, and the loss of dry matter is generally 10%. %about.
Second, extend the green feeding season: Although the green feed is very good, the seasons that can be used normally throughout the year are limited. For example, in the northwest of China, the green feeding season is less than half a year. There is a lack of green feed for livestock throughout the winter season. The use of silage fermentation agent fermentation silage approach can make up for the shortcomings of green feed in the use of time. In other words, using the silage method to modulate the feed is beneficial to the balanced supply of nutrients throughout the year.
Third, the palatability is good and easy to digest: in the process of silage fermentation produces large amounts of lactic acid, so the smell is fragrant, soft and juicy, good palatability, all kinds of livestock are fond of food, and stimulate the secretion of digestive glands in domestic animals, experiments have shown Silage can improve the utilization of digestibility, see Table 1

Silage 74 73 70 75 72
Fourth, the modulation is convenient and durable. Tibet: It is convenient to use Jinbao to ferment silage, it is used for one time, it is used for a long time, and it is not limited by the weather conditions in the process of modulation. After the silage fermentation is completed, if it is used up for the year, as long as it does not leak, long-term preservation will not deteriorate. When silage is stored, it is twice as small as hay, which saves storage space and is safe to store.
