Embodiment 1

[0035] This embodiment provides the preparation process of inactivated Lactobacillus salivarius and its fermentation product:

[0036] (1) Take Lactobacillus salivarius, use the conventional Lactobacillus culture medium (liquid MRS medium) in the field to make fermentation broth through conventional fermentation, centrifuge the fermentation broth, separate Lactobacillus salivarius cells and post-fermentation culture fluid ;

[0037](2) Take 4kg of Lactobacillus salivarius cells obtained after centrifugation, add 16L of sterile saline at about 40°C, stir well (do not stir violently) and mix evenly to make a suspension, heat it with steam, and pass it through Stir while steaming, and control the steam flow, so that the heating rate is controlled at about 1.5°C / min. After 20 minutes, the temperature rises to 70°C. Reduce the steam supply and start timing to keep warm. After 10 minutes, stop steaming and heat the bacterial suspension. Pour into 20kg of crushed ice, mix evenly so ...

Embodiment 2

[0042] (1) Get Lactobacillus salivarius, adopt conventional culture medium (liquid MRS culture medium) to make fermented bacterial liquid by fermentation;

[0043] (2) Concentrate 1000L of the fermented bacteria solution prepared in step (1) directly by thin film evaporation, lose 80% of water to 200L, then cool down to below 40°C, add 43kg each of maltodextrin and soluble starch, stir and mix evenly . Set the inlet temperature of the spray dryer to 170°C, the outlet temperature to 68°C, the feeding flow rate to be constant, and the compressor pressure to be 0.4Mpa. After drying, collect Lactobacillus salivarius and its fermented products, and check the number of lactic acid bacteria unit cells with a staining microscope.

[0044] Then carry out staining microscopic examination counting by the method for embodiment 1, compare the impact of two different methods in embodiment 1 and embodiment 2 on the integrity of Lactobacillus salivarius cells in Lactobacillus salivarius and i...

Embodiment 3

[0047] (1) Get Lactobacillus casei, adopt conventional culture medium to ferment and make fermented bacterial liquid (tomato juice culture medium), fermented bacterial liquid is centrifuged, isolates Lactobacillus casei thalline cell and cultured liquid after fermentation;

[0048] (2) Take 4kg of Lactobacillus casei cells obtained after centrifugation, add 14L of sterile saline at about 35°C, stir well (do not stir violently) and mix evenly to make a suspension, heat with steam, and pass through Stir while steaming, and control the steam flow, so that the heating rate is controlled at about 1°C / min. After 15 minutes, the temperature rises to 65°C. Reduce the steam supply and start timing to keep warm. After 10 minutes, stop steaming and heat the bacteria suspension. Pour into 20kg of crushed ice, mix evenly so that the temperature quickly drops below 30°C to obtain a cooled Lactobacillus casei suspension;

[0049] (3) Take 1000L of the fermented culture fluid separated in ste...

Abstract

The invention discloses a synbiotic feed additive. The synbiotic feed additive is composed of the following components in proportion by mass: 10-30 parts of inactivated Lactobacillus and its fermentation product, 60-80 parts of Bacillus natto bacteria powder, 60-80 parts of low Fructose 5-10, auxiliary materials 30-40, in which the cell density of inactivated Lactobacillus and its fermentation product is 108-1010 / g, and the total number of colonies of Bacillus natto powder is 108-109 CFU / g. It also discloses feed for weaned piglets containing the above-mentioned synbiotic feed additive, and the application of the synbiotic feed additive to partially or completely replace antibiotics in feeding weaned piglets. The synbiotic additive in the invention can enhance the immunity and growth performance of piglets, can effectively inhibit and control diarrhea, can partially or completely replace antibiotics, and is used in feed for weaned piglets.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a synbiotic feed additive and its application. Background technique [0002] With the improvement of the scale and intensification of the breeding industry, the production performance of animals and the output of livestock and poultry products have been significantly improved, but many problems have also followed. As the breeding density increases, the stress level of animals also increases, the immune function of the animal body decreases, and the resistance to various harmful microorganisms is also getting lower and lower. Make animals in a sub-healthy state for a long time, it is easy to be infected with various diseases. In actual production, adding antibiotics to feed can prevent diseases and improve economic benefits, but the continuous use of antibiotics will lead to many problems such as bacterial resistance and drug residues in animal products. With the enhancem...
