Abstract

The invention discloses a complex microbial inoculant as well as a preparation method and application thereof, belongs to the technical field of animal husbandry, relates to silage, and solves the problems that corncob silage is severe in dry substance loss and is low in fermentation quality. The complex microbial inoculant is prepared from lactobacillus rhamnosus ZXY7 with a preservation number of CGMCC NO.11849 and a preservation date of December 9, 2015 and pediococcus ethanolidurans NO.1 with a preservation number of CGMCC NO.11850 and a preservation date of December 9, 2015. The complex microbial inoculant can remarkably reduce generation of alcohol or volatile substances, is high in dry matter storage rate, and can be widely applied to other silages with high sugar content.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and relates to silage, in particular to a compound microbial agent, a preparation method thereof and an application in corn cob silage. Background technique [0002] Silage additives are an important part of the silage production process, which determines the quality of silage, and the quality of silage determines the quality of livestock products. [0003] About 50% of the silage in the domestic dairy farming industry is used in the form of TMR, and herbivores such as beef cattle and sheep are mainly fed separately. Whole plant corn silage is widely used in various dairy and breeding enterprises in my country. In order to achieve the purpose of effective feed utilization, secondary fermentation inhibitors are usually added to corn silage, acid agents and bacterial agents are added to alfalfa silage, etc. . Yeast can cause aerobic spoilage while relatively increasing the protein of silag...
