Problems solved by technology

[0002]Currently, the extensive use and abuse of antibiotics has brought a series of problems to animals, livestock products and the environment: animal pathogens have developed resistance to antibiotics, leading to an increase in the amount of antibiotics used; Long-term use of antibiotics causes the microecology of animals in the digestive tract to lose balance, causing infection; antibiotic residues in animal products lead to changes in human immunity and health effects
[0004] Lactobacillus paracasei is a kind of lactic acid bacteria, however, the existing Lactobacillus paracasei ( Lactobacillus paracasei ) The production process of fermented feed is relatively complex, requiring multiple sets of process equipment to cooperate with each other, cumbersome operation, large equipment investment, and low production efficiency. Ineffective

Embodiment 1

[0028] A preparation method of Lactobacillus paracasei fermented feed of the present invention comprises the following steps:

[0029] (1) Liquid fermentation of Lactobacillus paracasei: put the MRS liquid medium into the chamber of the fermentation equipment (the fermentation equipment can be a fermentation tank, a fermentation tank or a plastic container, and the fermentation equipment in Example 4 is selected in this embodiment) In the process, the liquid volume of the MRS liquid medium accounts for 20% of the volume of the cavity, and 115°C high-temperature steam is passed into the container for 20 minutes to complete the sterilization of the MRS liquid medium. After the sterilization is completed, cool down and sterilize the MRS The liquid medium is inoculated with Lactobacillus paracasei (strain preservation number: CICC 20296), the inoculum amount is 3%, the container is sealed after inoculation, and the paracasei milk is obtained after static culture at a temperature of...

Embodiment 2

[0038] A preparation method of Lactobacillus paracasei fermented feed of the present invention comprises the following steps:

[0039] (1) Liquid fermentation of Lactobacillus paracasei: put the MRS liquid medium into the chamber of a fermentation equipment (the fermentation equipment in Example 4 was selected in this embodiment), the liquid volume of the MRS liquid medium accounts for 25% of the volume of the cavity, inject high-temperature steam at 115°C into the container for 20 minutes to complete the sterilization of the MRS liquid medium, cool down after the sterilization is completed, and carry out Lactobacillus paracasei (strain preservation) on the MRS liquid medium No.: CICC 20296), the inoculum amount is 6%, the container is sealed after inoculation, and the liquid of Lactobacillus paracasei is obtained after static cultivation at a temperature of 37°C for 48 hours, and the fermentation liquid of Lactobacillus paracasei is obtained. The number of bacteria contained ...

Abstract

A Lactobacillus paracasei fermented feed and its preparation method, fermentation equipment and application. The preparation method includes the steps of liquid fermentation of Lactobacillus paracasei and solid fermentation of Lactobacillus paracasei. High efficiency, low energy consumption and other advantages. The fermentation equipment includes a support seat, a fermentation tank and a stirring assembly installed in the fermentation tank. The fermentation tank includes a tank body with a material inlet and outlet and a sealing cover for sealing the material inlet and outlet. The sealing cover is movably connected with the tank body, and the tank body can be The swinging device is installed on the support seat, and the support seat is equipped with a swing drive assembly for driving the tank to tilt and discharge. It has the advantages of compact structure, small footprint, simple operation, beautiful appearance, convenient cleaning, good mixing effect, and can greatly reduce the Labor intensity and other advantages. The Lactobacillus paracasei fermented feed and its use have the advantages of being able to significantly reduce the incidence of post-weaning diarrhea in piglets, increase the growth rate of pigs, and improve the efficiency of feed conversion and utilization.

Description

technical field [0001] The invention relates to the field of microbial fermentation, in particular to a Lactobacillus paracasei fermented feed and a preparation method, fermentation equipment and application thereof. Background technique [0002] At present, the extensive use and abuse of antibiotics has brought a series of problems to animals, livestock products and the environment: animal pathogens develop resistance to antibiotics, leading to an increase in the use of antibiotics; long-term use of antibiotics causes the microecology of animals in the digestive tract to lose balance, causing infection ; Antibiotic residues in animal products cause changes in human immunity and affect health. People gradually realize the potential harm of antibiotics to humans and animals. Therefore, in animal nutrition research and animal breeding, people spend a lot of effort on researching antibiotic substitutes and their application promotion. [0003] The development of green, safe an...
