Problems solved by technology

In the silage process, there are many types of microorganisms, including some spoilage bacteria and molds that use the squeezed juice to reproduce in large numbers, which directly leads to the failure of the silage.
At present, there are more than 200 kinds of silage additives used in the world, including microbial additives and chemical additives. Therefore, in actual production, the choice of weight and usage of silage additives determines the quality of silage; chemical additives must be fully used Mix evenly, otherwise livestock will be prone to poisoning after eating, and at the same time will cause adverse effects on livestock products, so chemical additives are not easy to be the first choice for silage additives
[0003] At present, lactic acid bacteria are mostly used in sweet sorghum silage, but their strains are single, and it is difficult to adapt to the new environment. At the same time, the impact on the micro-ecosystem in the entire silage is extremely limited, which will cause fermentation instability and affect Fermentation qua

Example Embodiment

[0030] Example 2

[0031] A composite microbial additive to increase the quality of the silage is used as a fermentation accelerator in the preparation of high-quality silage. It is specifically based on sorghum straw as a silage raw material, and high quality silage is prepared as a fermentation promoter in Example 1 as a fermentation promoter. Feed, including the following steps:

[0032] (1) Material preparation:

[0033] Sorghum straw (strain): Provided by Hunan Longping Gaoke Cultivated Land Rehabilitation Technology Co., Ltd., various varieties of sorghum productivity, as shown in Table 1.

[0034] Table 1 Different varieties of sorghum productive

Abstract

The invention discloses a compound microbial additive for improving silage quality and application of the compound microbial additive. The compound microbial additive comprises pediococcus acidilactici liquid, lactobacillus plantarum liquid, bacillus natto liquid and candida utilis liquid in a volume ratio of 1:1:1:1. According to the application, the compound microbial additive is used as a fermentation accelerant for preparing high-quality silage. The compound microbial additive disclosed by the invention has the advantages of low cost, good fermentation stability, high safety and the like, can obviously improve the quality of the silage, has relatively high adaptive value and relatively good application prospect, and can obtain high-quality silage when being used as a fermentation accelerant for preparing the silage. The compound microbial additive has the advantages of simple process, convenience in operation, easiness in control, low raw material cost, low energy consumption, short time consumption, environment friendliness and the like, is suitable for continuous large-scale batch production, is convenient for industrial utilization, and shows a good application prospect.

Description

technical field [0001] The invention relates to a compound microbial additive for improving the quality of silage and its application. Background technique [0002] Silage bacteria agent, as a kind of microbial additive specially used for feed silage, its main function is to regulate the microbial population in the silage process, adjust the silage fermentation process, in order to achieve the purpose of preserving silage nutrients and improving silage quality. In the silage process, there are many types of microorganisms, including some spoilage bacteria and molds that use the squeezed juice to reproduce in large numbers, which directly leads to the failure of the silage. At present, there are more than 200 kinds of silage additives used in the world, including microbial additives and chemical additives. Therefore, in actual production, the choice of weight and usage of silage additives determines the quality of silage; chemical additives must be fully used Mix well, other...
