Abstract

The invention belongs to the technical field of feed processing, and in particular relates to a preparation method of silage. The preparation method comprises the following steps: (1) preparing fermentation liquor; (2) preparing raw materials; (3) carrying out treatment of silage: covering the wall of a cellar with a film, then putting silage mixture into the cellar, firstly laying the silage mixture with thickness of 5-8cm over the cellar and then pouring liquid with the fermentation liquor, tamping next, then laying the silage mixture upward, repeating the previous steps until the cellar is fully filled, and then sealing the cellar. The method provided by the invention is simple and convenient in operation; the silage not only maintains the nutrient of a silage raw material, but is also good in mouth feel.

Description

【Technical field】 [0001] The invention belongs to the technical field of feed processing, and in particular relates to a method for preparing silage. 【Background technique】 [0002] Silage is obtained by chopping green feed with a moisture content of 65%-75%, and then forming an acidic environment through the fermentation of anaerobic lactic acid bacteria under the condition of airtight anoxic conditions, and inhibiting the reproduction of various bacteria. A kind of roughage. Silage has a sour and fragrant smell, is soft and juicy, has good palatability, is rich in nutrition, and is good for long-term preservation. Silage is made by anaerobic fermentation of green feed. Its production principle is to promote the proliferation of lactic acid bacteria in an anaerobic environment, so that soluble sugar can be converted into lactic acid and accumulate to a certain concentration; after lactic acid bacteria ferment and decompose sugar, the produced Carbon dioxide further remove...
