Problems solved by technology

[0004] The appearance score of sugarcane caudal leaves was higher after natural silage, but the aerobic stability was poorer after exposure to air, mainly due to the higher content of ammoniacal nitrogen and butyric acid in the feed of natural silage sugarcane caudal leaves, while ammoniacal nitrogen represented the The decomposition of protein and amino acid in the feed, the smaller the ratio of ammonia nitrogen to the total nitrogen, the better the nutritional value of the feed is preserved

Embodiment 1

[0027] A kind of lactic acid bacteria combination preparation for sugarcane tail leaf silage according to the present invention has the following 4 forms: (1) Lactobacillus plantarum+Lactobacillus casei+Lactobacillus fermentum, (2) Lactobacillus plantarum+cheese milk Bacillus + Lactobacillus rhamnosus, (3) Lactobacillus plantarum + Lactobacillus fermentum + Lactobacillus rhamnosus, (4) Lactobacillus casei + Lactobacillus fermentum + Lactobacillus rhamnosus.

[0028] For the 4 kinds of lactic acid bacteria combinations used in the lactic acid bacteria combination preparation, the test strains need to be activated and expanded, and the strains in the -80°C glycerol cryopreservation tube are activated, and transferred to the MRS liquid medium at a 3% inoculation amount. Lactobacillus plantarum , Lactobacillus casei, Lactobacillus fermentum and Lactobacillus rhamnosus are cultured at 37°C, and cultured at a static constant temperature for 24h-48h, until white flocculent floating ma...

Abstract

A lactic acid bacteria combination preparation for sugarcane tail leaf silage and its application. The lactic acid bacteria combination preparation is prepared by combining Lactobacillus plantarum, Lactobacillus fermentum, Lactobacillus rhamnosus and Lactobacillus casei in a certain proportion. The application of the lactic acid bacteria combination preparation in sugarcane tail leaf silage, that is, adopting the described lactic acid bacteria combination preparation to silage sugarcane tail leaves. The application of the lactic acid bacteria combination preparation provided by the present invention in silage sugarcane tail leaf can effectively improve the aerobic stability of sugarcane tail leaf silage, improve the dry matter recovery rate of sugarcane tail leaf silage, and reduce the ammoniacal nitrogen content of sugarcane tail leaf silage. Ratio of total nitrogen and butyric acid content.

Description

technical field [0001] The invention belongs to the technical field of silage production, in particular to a lactic acid bacteria combination preparation for sugarcane tail leaf silage and an application thereof. Background technique [0002] Guangxi is the main sugarcane planting area in my country. Winter is the harvest time of sugarcane. There are a large number of sugarcane tail leaves available. Silage is an effective storage method to preserve the feed nutrients of sugarcane tail leaves. [0003] The dry matter content of sugarcane tail leaves is 28.5%-36.60%, and the crude protein content is 5.13%-5.97%, which is a kind of roughage of medium quality. In Guangxi, the harvesting season of sugarcane lasts from November to April of the next year, which is a period of high humidity in Guangxi. Therefore, it is unrealistic to dry the tail leaves of sugarcane to make hay, and it is easy to cause mildew when stacked. Burning not only It pollutes the air and causes a waste of...
