Embodiment 1
[0060] Preparation of Bacillus subtilis culture:
[0061] Obtain Bacillus subtilis fermentation broth by step-by-step expansion culture of slant strains;
[0062] (1) Primary seed culture: Inoculate the slant strain of Bacillus subtilis into a 500 ml shake flask, with a medium capacity of 100 ml, a rotary shaker at 180 rpm, a culture temperature of 40°C, and a culture time of 12 hours;
[0063] (2) Secondary seed cultivation: Put the first-grade seeds into 500 ml second-grade seed shake flasks according to the inoculation amount of 10%, and the cultivation conditions are the same as the first-grade seeds;
[0064] (3) Tertiary seed cultivation: Inoculate the secondary seeds with 10% inoculum volume into a 5000 ml tertiary seed shaker flask, with a medium capacity of 1000 ml, a rotary shaker at 100 rpm, and a culture temperature of 40°C. Time 12 hours;
[0065] (4) First-level seed tank cultivation: put the third-level seeds into the first-level seed tank with a total volume ...
Embodiment 2
[0072] A feed additive comprises the following raw materials in parts by weight: 11 parts of perilla extract, 9 parts of yeast cell wall extract, 25 parts of Bacillus subtilis culture, 7 parts of Astragalus extract; 4 parts of Codonopsis pilosula extract; 3 parts of fructooligosaccharide parts; the above-mentioned ratios are ratios by weight; the preservation number of Bacillus subtilis Li-2013-02 is CGMCC No.7926.
Embodiment 3
[0074] The production method of the feed additive product described in Example 2: the yeast cell wall extract and fructooligosaccharides are crushed through a 60-mesh sieve, and the above-mentioned crushed product is mixed with perilla extract, Bacillus subtilis culture, astragalus extract, and Codonopsis pilosula extract in proportion Mix to obtain the plant extract compound feed additive.
[0075] Preparation of astragalus extract:
[0076] Crush the raw material astragalus until the particle size is less than 2 mm, add 4 times the weight of water to the container and mix evenly, control the temperature at 80°C, keep it for 2.5h, adjust the pH value to 6.2 with lactic acid, cool down to 50°C, add mixed enzymes, After 3 hours of enzymatic hydrolysis, a mixture of ethanol and propanol 1.5 times the weight of the mixed material was added, the temperature was controlled to 70° C., kept for 3 hours, and filtered; the filtrate was concentrated in vacuum and then freeze-dried.
