Corn straw silage feed preparing technology

Abstract

The invention discloses a corn straw silage feed preparing technology. A corn straw silage feed is prepared through the steps of preparing a silage pond, collecting and sorting silage feed raw materials, performing cutting-up, adding a feed additive, performing loading, closing over dry substances, performing film coating pretreatment, and performing earth coating for sealed storage. According tothe corn straw silage feed prepared by the corn straw silage feed preparing technology disclosed by the invention, the content of a hazardous substance, namely flavatin, in the feed is reduced, the mildew and rot rate of the feed is reduced, and the mouth feel and the quality of the feed are improved; besides, the silage feed is not liable to decompose due to silage, the silage loading void content is reduced, and favorable anaerobic environment can be created for lactic acid bacteria fermentation, so that fermentation is facilitated; a layer of the dry substances are covered, so that the situation that a large quantity of nutrient components run off along with moisture is avoided, nutrient loss is reduced, and the fragrance of lactic acid of the silage is improved; and the feed additive is added, so that the quality of the silage feed can be improved, the food consumption of the feed is increased, and the palatability of the feed is strengthened.

Description

technical field [0001] The invention relates to the field of silage, in particular to a production process of corn stalk silage. Background technique [0002] Silage refers to the compaction and sealing of fresh plant varieties, so that the stored green fodder is isolated from the outside air, resulting in internal hypoxia and anaerobic fermentation, thereby producing organic acids, which can keep the fresh silage for a long time, and can reduce the A storage technique or method in which nutrient loss is beneficial to animal digestion and absorption. [0003] Most of the crops in northern my country are ripe once a season, so there will be a shortage of forage in autumn and winter, especially fresh green forage; most farmers feed on hay, which greatly reduces the forage In Northwest China, the climate is cold, the growth period is short, and the production of green fodder is limited. There is a lack of green fodder throughout the winter and spring seasons. The silage is prep...

Problems solved by technology

If the water content of the silage is too high during silage preparation, a large amount of nutrients will be lost with the water during the compaction process, resulting in a lot of waste, and the silage made has a high pH and a pungent sour smell; The number of lactic acid bacteria contained in the silage is limited, and it is difficult to quickly form lactic acid fermentation, which makes the spoilage bacteria active for too long, and the pH of the silage drops slowly, resulting in excessive nutritional loss of the silage, and even causing silage corruption; at the same time, the silage is in the fermentation process Parts are prone to mildew and rot, especially on the top, where the rot is serious, causing a large number of mold and spoilage bacteria to multiply. Due to the presence of a large number of miscellaneous bacteria, when the silage is opened, it is easy to form secondary fermentation. Mildew spots or moldy patches appear on the surface, and if the situation is not good, it will cause complete mildew and rot
