Problems solved by technology

However, just as all the achievements of industrial civilization have its negative effects, the long-term use of non-green feed additives such as antibiotics has caused the following problems: serious drug residues in livestock and aquatic products, which directly endanger human health; livestock and poultry and The quality of aquatic products has declined, lacking market competitiveness and trust; bacterial resistance has increased, and drug-resistant strains have increased, threatening human safety; destroying the ecological environment, etc.
However, the existing Chinese herbal medicine fermentation strains are normal temperature strains, and the activity of non-starch polysaccharide enzymes produced during the fermentation process will be completely lost in the process of product drying and high-temperature granulation of feed
Therefore, the fermented Chinese herbal medicine prepared by the existing Chinese herbal medicine fermentation technology can only exert the effect of Chinese herbal medicine in the animal body, and cannot exert the effect of enzyme preparation

Embodiment 1

[0026] Embodiment 1: the thermostable Bacillus subtilis ( Bacillus subtilis ) HL-2 was inserted into the LB liquid medium cooled after sterilization, and cultured at 55°C and 150r / min for 12h to prepare Bacillus subtilis ( Bacillus subtilis ) HL-2 seed solution for use. Grind Houttuynia cordata and pass through a 60-mesh sieve for later use. Weigh 100 kg of pulverized Houttuynia cordata, add 5200 g of bran, 380 g of calcium chloride, 390 g of ferrous chloride, 480 g of ammonium sulfate, 550 g of dipotassium hydrogen phosphate and 95 kg of water, mix well The fermentation culture that obtains after; Add 8 kilograms of bacillus subtilis ( Bacillus subtilis ) HL-2 seed solution, stirred and mixed evenly; the inoculated fermentation medium was divided into shallow fermentation pans that had been surface-sterilized with 75% alcohol. The thickness of the material in the shallow pan was 8 cm, and the surface of the material in the shallow pan was Cover the sterilized wet gauze, an...

Embodiment 2

[0027] Embodiment 2: the thermostable Bacillus subtilis ( Bacillus subtilis ) HL-2 was inserted into the LB liquid medium cooled after sterilization, and cultured at 55°C and 150r / min for 12h to prepare Bacillus subtilis ( Bacillus subtilis ) HL-2 seed solution for use. Glycyrrhizae and Radix Astragali are crushed and passed through a 60-mesh sieve for later use. Weigh 100 kg of crushed Chinese herbal medicine (70 kg of licorice + 30 kg of astragalus), and add 5600 g of bran, 490 g of calcium chloride, 460 g of ferrous chloride, 550 g of ammonium sulfate, and 560 g of dipotassium hydrogen phosphate and 90 kilograms of water, the fermentation culture obtained after mixing; add 9 kilograms of Bacillus subtilis ( Bacillus subtilis) HL-2 seed solution, stirred and mixed evenly; the inoculated fermentation medium was divided into shallow fermentation pans that had been surface-sterilized with 75% alcohol. The thickness of the material in the shallow pan was 6 cm, and the surface ...

Abstract

The invention discloses a method for preparing a compound type growth-promoting feed additive by fermenting Chinese herbal medicines. The method comprises the following main steps: crushing the Chinese herbal medicines and sieving with a 60-mesh sieve for later use; adding nutrients and water into the crushed Chinese herbal medicines, and uniformly mixing to obtain a fermentation culture medium; inoculating high-temperature-resisting bacillus subtilis HL-2 into the fermentation culture medium and carrying out solid-state aerobic fermentation at 50-55 DEG C for 48-60 hours; and drying, crushing and packaging a fermented product to prepare a feed additive finished product. With the adoption of the method disclosed by the invention, the fermentation effect of the Chinese herbal medicines can be improved, and the prepared fermented Chinese herbal medicines also contain rich high-temperature-resisting non-starch polysaccharide enzyme, so that antibacterial and growth-promoting performances of the fermented Chinese herbal medicine product are further improved, and an application prospect is good.

Description

technical field [0001] The invention relates to a method for preparing a compound growth-promoting feed additive by fermenting Chinese herbal medicine, and belongs to the technical field of feed additive preparation. Background technique [0002] Since the 1950s, antibiotics, chemically synthesized drugs, hormones, β-stimulants, heavy metals, sedatives and other growth-promoting health care agents have been widely used in animal feeding and feed. Antibiotics and other growth-promoting health-care agents have been used in feed for a long time. It has created a revolution in the breeding industry and feed industry, which has led to the rapid development of large-scale farming all over the world, and the production quantity and feed conversion rate of animals have been greatly improved. increase in magnitude. However, just as all the achievements of industrial civilization have its negative effects, the long-term use of non-green feed additives such as antibiotics has caused t...
