Abstract

The invention belongs to the technical field of biological fermentation and in particular relates to a feed microecological preparation and a preparation method thereof. The preparation method comprises the following steps: (1) preparing lactobacillus acidophilus, saccharomyces cerevisiae and bacillus subtilis; (2) preparing a solid culture medium by uniformly mixing the following raw materials: bran, apple pomace, corn meal, brown sugar, dipotassium phosphate and ammonium sulfate according to certain amounts; sterilizing and adding water for adjusting the content of the water; (3) inoculating twice and fermenting stage by stage. According to the feed microecological preparation, the growth state of a large quantity of microbial strains is good, and a fermentation culture medium is sour and fragrant in taste, good in palatability and favorable for being used in a feed. According to the preparation method, the process of inoculating twice and fermenting stage by stage is adopted and good material conditions and growth environments are provided.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a feed microecological preparation and a preparation method thereof. Background technique [0002] The research and application of animal microecological preparations can be traced back to 1947. Mollgaard first discovered that feeding piglets with Lactobacillus can effectively increase body weight and improve health. However, the middle and latter part of the last century was the golden age of antibiotic research, production and use, which made the research and development of probiotics at a low ebb. In recent years, due to the extensive use of antibiotics and synthetic drugs in the aquaculture industry, the safety hazards of animal-sourced food and environmental pollution have been caused, causing serious social, economic and ecological problems, and microecological preparations have become a research hotspot again. [0003] Feed probiotics are probi...
