Lactic acid bacteria additive for silage for multiflora ryegrass and preparation method thereof

Abstract

The invention discloses a lactic acid bacterium additive for ensiling Lolium multiflorum and a preparation method of the lactic acid bacterium additive, wherein the lactic acid bacterium additive can be used for improving the fermentation quality and nutritional value of an ensilage. The additive is prepared by mixing a first strain and a second strain, wherein the first strain is lactobacillus plantarum (LP), the second strain is any one selected from lactococcus lactis (LL), Weissella confusa (WF) and Weissella cibaria (WB), and the volume ratio of the first strain to the second strain is 1: (1-3). The lactic acid bacterium additive is added into a Lolium multiflorum ensilage when Lolium multiflorum is ensiled, so that the fermentation quality and nutritional value of the ensilage can be greatly improved; the lactic acid bacterium additive is prepared by separating lactic acid bacteria which are high in acid productivity, vigorous in growing and capable of improving the fermentation quality and nutritional value of the Lolium multiflorum ensilage from lactic acid bacteria attached on Lolium multiflorum, is more suitable for ensiling Lolium multiflorum, and is also suitable for popularization and application in the ensiling field.

Description

technical field [0001] The invention belongs to the field of silage, and in particular relates to a lactic acid bacteria additive for silage used for ryegrass multiflora and a preparation method thereof. Background technique [0002] Silage is the process of converting the fermentation substrate in raw materials into acidic substances such as lactic acid through the proliferation of lactic acid bacteria, creating an acidic environment, inhibiting the proliferation of harmful microorganisms, and thus preserving the nutritional content of raw materials. High-quality silage not only maintains the fresh green color and most of the nutrients of green feed, but also increases the content of crude protein; at the same time, it has the characteristics of aromatic sour taste, soft and juicy, and good palatability. There are a variety of lactic acid bacteria in silage, including Lactobacillus, Enterococcus, Leuconstoc, Lactococcus and Pediococcus, etc. In order to improve the quality ...
