Abstract

The invention provides a production method of silage. The method comprises the following steps: firstly, producing a fermented material, then reaping fresh pasture, cutting the pasture after being aired to contain proper water, mixing the fermented material with the pasture to be stored during cutting according to the ratio, putting the mixture into a silage pool, and fermenting for 25-50 days to acquire the silage. The production method is simple and easy to implement, low in cost, high in efficiency and strong in practicability; during the production, the dosage of lactobacillus is small; the produced silage is yellow green, obvious in smell of sour and fragrance, not pungent, wet, compact and easy to separate; most of stems and leaves of the silage keep the original state and veins are clearly visible; the tastiness is good, the content of lactic acid in the silage (fresh samples) can reach 1.6%, and the pH value is 3.8-3.9; the loss of main nutrients is smaller than 8%; the fermentation time is shortened while high-quality of the silage is ensured.

Description

technical field [0001] The invention relates to a production method of silage. Background technique [0002] Silage is obtained by chopping green feed with a moisture content of 65% to 75%, and then forming an acidic environment through the fermentation of anaerobic lactic acid bacteria under airtight and hypoxic conditions to inhibit 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 The carbon dioxide further removes the air, and the secreted lactic acid makes the feed weakly acidic (pH 3.5-4.2), ...
