Abstract

High-quality silage is formed by carrying out silage fermentation of mixed forage grass composed of 50%-60% of dactylis glomerata, 20%-40% of setaria grass and 10%-20% of ramie according to the weight percentage. The prepared mixed silage is yellow green, has obvious sour and fragrant flavor, is not pungent, moist and compact, is easy to separate, has stems and leaves maintained with the original states, and has clear and visible leaf veins; the silage has good palatability, the lactic acid content in the silage (fresh sample) is high, the pH value can reach 3.8, and the maximum pH is not more than 4.2; the loss of main nutrients of the silage is 6% or less, the main nutritional quality is close to that of silage raw materials, and the silage has good palatability, has corresponding ruminant animal feed intake, digestibility rate of organic matters and the effective energy value all similar to those of the silage raw materials, and has good nutritional quality.

Description

technical field [0001] The invention relates to high-quality silage, in particular to mixed silage and a production method thereof. Background technique [0002] 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 removes the air, and the secreted lactic acid makes the feed weakly acidic, which can effectively inhibit the growth of other microorganisms, thereby effectively inhibiting spoilage bacteria, so that the nutrients in the silage can be preserved for a long time. [0003] In the process of silage production, it is difficult to quickly form the fermentation of lactic acid-dominant bacteria, which makes the spoilage bacteria active for too long, and the pH of the silage...
