Compound microbial feed additive, preparation process and use thereof

Abstract

The invention relates to a composite microbe forage additive and relative production, wherein said additive comprises Saccharomyces cerevisiae, Lactobacillus plantarum, and Lactobacillus casei subsp.casei, which are processed via slope cultivation, first-stage seeding, second-stage seeding, and mixture cultivation ferment, to optimize the ratio between composite bacterial. The effective viable bacterial number of said additive is more than 2*109cuf / mL. The inventive forage additive can improve the forge utilization and immunity ability, with reduced cost.

Description

technical field

[0001] The invention relates to a compound microbial feed additive, its production method and use as an animal feed additive. technical background

[0002] Microbial feed additives are preparations made by selecting normal microbial strains and growth-promoting substances in animals according to the theory of micro-ecological balance, micro-ecological imbalance, micro-ecological nutrition and micro-ecological control. my country's feed additives are divided into 12 categories such as feed-grade amino acids, enzyme preparations, microbial additives, antioxidants and stabilizers.

[0003] Among them, microbial preparations and enzyme preparations are widely used because of their obvious use effects and no antibiotics, hormones and pesticide residues, which conform to the current food safety concept.

[0004] At present, there are varieties of microbial feed additives on the market at home and abroad. Foreign products include "Probios" "Biomaax40 TM ""Primala...
