Dactylis glomerata-containing silage and preparation method thereof

Abstract

The invention discloses dactylis glomerata-containing silage. The dactylis glomerata-containing silage is formed by fermenting mixed pasture which serves as raw silage and is prepared from the following components in percentage by weight: 50 to 60 percent of dactylis glomerata, 10 to 20 percent of ramie and 20 to 40 percent of Leshi broomcorn-sudangrass hybrid pasture. The mixed silage prepared by the preparation method is yellow-green, obvious in sour fragrance, wet, close, easy to separate, and is not pungent; stems and leaves are mostly kept in original states; leaf vines are clear and visible; the palatability is high; the lactic acid content in the silage (a fresh sample) is high; the pH value can reach up to 3.6; the maximal pH does not exceed 4.0; the loss of main nutrients of the silage is 6 percent or below; the quality of the main nutrients is close to that of silage raw materials; the silage has high palatability; the feed intake, the organic matter digestibility and the effective energy value of ruminants are all similar to those of the silage; the nutritional quality is good.

Description

technical field [0001] The invention relates to the preparation of silage, in particular to a method for rapidly fermenting and preparing silage. 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] At present, in most silage preparation processes, it is difficult to quickly form the fermentation of lactic acid dominant flora, which makes the spoilage bacteria active for too long, ...

AI Technical Summary

Problems solved by technology

The growth of many high-quality forages such as alfalfa promoted in China cannot achieve the expected results. Therefore, it is imminent to dig out the resources of forage varieties and find high-quality, high-yield and silageable forages that meet the balanced development of forage and livestock.
