Inactivated lactobacillus micro-ecological preparation and preparation method thereof

The invention discloses an inactivated lactobacillus micro-ecological preparation and a preparation method thereof. The preparation comprises the following components in portion by mass: 10 to 60 portions of inactivated lactobacillus cell and lactobacillus fermentation product, and 30 to 50 portions of excipient, wherein the inactivated lactobacillus cell accounts for 10 to 10 cells per gram. The inactivated lactobacillus cell resists high temperature, gastric acid and bile, and has synergistic action with antibiotics; in addition, metabolic products produced in a lactobacillus fermentation process such as lactic acid, like bacteriocin and the like can effectively inhibit or kill enteric pathogenic bacteria of people or animals; and enzymes such as amylase, lactase and the like are helpful for digestion of the animals. The inactivated lactobacillus micro-ecological preparation effectively and economically solves the problem puzzling the prior viable bacteria micro-ecological preparation.
