Alfalfa silage agent and preparation method thereof

Abstract

The present invention discloses an alfalfa silage agent and a preparation method thereof. The alfalfa silage agent comprises the following components in parts by mass: 4.5 parts of lactobacillus plantarum, 3 parts of lactobacillus acidophilus, 2.5 parts of pediococcus acidilactici, 2.5 parts of lactobacillus reuteri, 2 parts of bacillus subtilis, 1.5 parts of bacillus coagulans and 1 part of cellulase. The alfalfa silage agent is successfully developed by screening high-performance lactic acid bacteria and carrying out scientific compatibility aiming at characteristics of nutritional ingredients of alfalfa, can realize rapid reduction of pH value of alfalfa silage raw materials, inhibits various infectious micro-organisms of acetic acid bacteria, yeasts, enterobacteria, clostridium, bacillus, mould, listeria, etc., and produces high-value high-quality alfalfa silage feeds.

Description

technical field [0001] The invention relates to an alfalfa silage agent and a preparation method thereof. Background technique [0002] Alfalfa is a perennial herbaceous plant of the leguminous family. It has high protein content, rich digestible fiber, and good palatability. It is a high-quality protein feed. Due to the need for large-scale production, alfalfa needs silage to reduce the loss of protein and other nutrients and maintain its green characteristics. However, the content of soluble carbohydrates in alfalfa is low. Compared with corn and grasses, the silage fermentation speed is slower and the pH value drops slower, so it is difficult to achieve the best fermentation state by conventional fermentation, and it is difficult to silage. Leguminous forage. [0003] Alfalfa silage management should pay attention to the following points: 1. The best cutting time; 2. Cutting length; 3. Dry matter content; 4. The silage is compacted into the cellar; However, although th...

Problems solved by technology

However, although the above points are implemented in the silage management process, the quality of silage will still be poor, or may fail. The main reason is that with environmental pollution, the types and quantities of lactic acid bacteria that naturally grow in plants are decreasing, and miscellaneous bacteria and spoilage bacteria The content of targeted lactic acid bacteria is relatively low, and it is impossible to quickly ferment the sugar in the raw material of alfalfa silage to generate lactic acid and quickly reduce the pH value to inhibit the growth and reproduction of other bacteria
