Why are forage membranes stored?

- Dec 25, 2018-

Since ancient times, Chinese farmers have a tradition of using crop straw as fodder to feed livestock. However, with the rapid development of animal husbandry in China, the continuous adjustment of planting structure, the further implementation of the strategy of Western development and the gradual implementation of the National ecological Construction plan, as well But the ensuing storage problem is also becoming more and more prominent. The traditional method of storage is cellar storage or tower storage. However, the traditional method of preservation because of the lack of closeness, too much oxygen in the straw, the effect of preservation is not ideal.

Too much oxygen in the orange pole will prolong the oxygen demand stage, protein degeneration, a large number of soluble carbohydrates are consumed, digestible protein greatly reduced, thus greatly reducing the quality of the feed. With the development of science and technology, people have become more and more aware of the fermentation modulation mechanism of silage, and invented the special film of Silage. The principle is to harvest the fresh alfalfa, corn straw and other green plants with bundles of high-density compaction bundles, and then wrapped in silage special film, resulting in an optimal fermentation environment.

After such bundles and wrapped grass, in a sealed state, under anaerobic conditions, after 3-6 weeks, the ph value will be reduced to 4, at this time all microbial activities are stopped, and finally complete the biochemical process of natural fermentation of lactic acid, so as to achieve satisfactory silage effect, and can be stored in the wild for 1-2 years. Good forage film wrapped in alfalfa or straw, should meet the following criteria: ph value 4, moisture 50%-65%, lactic acid 4%-7%, acetic acid less than 2.5%, butyric acid less than 0.2%,N-NH3 accounted for total nitrogen 5%-7%, ash less than 11%.The use of this technology provides quality feed for livestock all year round.
