Background
Antibiotics refer to a class of substances produced by bacteria, fungi, or other microorganisms that have anti-pathogenic or other activity. Due to the abuse of antibiotics in recent years, pathogenic bacteria develop resistance to antibiotics and antibiotics may remain in animal products. With the increasing emphasis on food safety in recent years, the focus is on finding antibiotics for feeding, and solving the problem of animal-derived food safety. The Chinese herbal medicine additive has unique advantages in promoting animal growth and improving immunity, so that research strength of the Chinese herbal medicine as the feed additive is further increased, and the Chinese herbal medicine anti-cancer additive has a wide application prospect in development and application of a reliable curative effect, small toxic and side effects, convenience in application and low cost.
Mangosteen, originally named mangosteen, is a plant of the genus garcinia of the family garciniaceae, and is mainly distributed in southeast Asia countries such as Thailand, Vietnam, Malaysia, Indonesia, Philippines, and the like. The pericarp of the mangosteen is always used as a traditional medicine in southeast Asia countries for treating diseases such as abdominal pain, diarrhea, dysentery, cholera, infected wounds, suppuration, chronic ulcer and the like, and modern scientific researches find that the pericarp of the mangosteen contains various active ingredients including bispyridone, phenolic acid, polysaccharide, pigment and the like, has pharmacological activities in various aspects such as anti-inflammation, antibiosis, malaria prevention, blood fat reduction, antioxidation, HIV resistance, immunoregulation and the like, is a plant resource with multiple effects, and is worthy of deep research and wide popularization. The xanthone compound is considered as a main active ingredient of mangosteen shell with drug effect and health care value, and the main active ingredient of the xanthone compound is mangostin (mangostin), so that the xanthone compound has good effect in the field of antibiosis and antiphlogosis.

The patent methods adopt conventional extraction processes such as leaching, thermal reflux, ultrasonic and the like, and are difficult to completely break firm cell walls of the mangosteen shell powder raw material, so that effective components in plants cannot be well extracted and utilized, not only is resource waste caused, but also the prospect of the mangosteen extract as an antibacterial raw material is influenced. In fact, many polyphenols and polysaccharides exist in the mangosteen besides antibacterial substances such as mangostin, and substances with low application value in mangosteen shells are further converted into substances with high application value by a fermentation method, so that the application value of the mangosteen extract is improved. Based on the background, the invention further researches the physical and biotransformation extraction method of the mangosteen, so as to further obtain the process technology of the mangosteen extract which is more comprehensive and more suitable for being used as a feed additive for replacing antibiotics than the common extract, and particularly obtain the application method of the extract.

The experimental results show that: the number of dead chicks in the experimental group is 6, and the weight of the chicks is increased by 2.08kg in 15 balances; the number of dead chicks in the control group is 25, and the average weight is increased by 1.77 kg.
Experiments show that the mangosteen extract prepared by the invention has a certain antibiotic effect on broiler chickens, has a growth promoting function, and can be used as a natural extract feed additive for replacing antibiotics to be used for poultry breeding. Although aquatic and mammalian studies have not been conducted, it is anticipated that the mangosteen extract prepared by the present invention may also have antibacterial and growth promoting effects in other animal breeding fields.

Claims (6)

1. A mangosteen fermentation extract is characterized by adopting the following preparation steps:
1) drying or baking fresh mangosteen, crushing the raw materials, and sieving the crushed raw materials with a 20-mesh sieve to obtain a mangosteen shell crushed material;

3) adding activated composite microbial strain culture solution into the homogenate, and performing fermentation culture at 32-36 deg.C and 160 r/min; the formula of the culture medium for activating the strains is 10.0g/L peptone, 10.0g/L yeast extract, 2.0g/L diammonium hydrogen citrate, 0.6 g/L magnesium sulfate, 2.0g/L dipotassium hydrogen phosphate, 0.3 g/L manganese sulfate, 1.0mL of Tween-80 and the pH value of the culture medium is 6.2-6.6;
the activated composite microbial strain is prepared by culturing lactobacillus plantarum powder and saccharomyces cerevisiae powder in a ratio of 1:3 in a liquid culture medium until the number of bacterial colonies reaches 108Liquid spawn of CFU/ml; the inoculation mass of the composite microbial strain culture solution is 15-20% of the mass of mangosteen homogenate, and the fermentation time is 72 h;
4) filtering the fermented substance; adding 60-80% ethanol into the filter residue according to the mass ratio of 1:5-1:7, performing ultrasonic extraction for 30min, filtering, and repeating the above operation once; mixing the three filtrates, vacuum concentrating under reduced pressure to more than 10 Baume degree, stirring, homogenizing, adding appropriate adjuvants, and spray drying to obtain powdery mangosteen extract rich in mangostin, polypeptide, polyphenol, and probiotic.
2. Use of the mangosteen extract of claim 1 in animal feed stocks.
3. Use of the mangosteen extract according to claim 1 in a poultry farming feed.
4. Use of the mangosteen extract of claim 1 in broiler breeding feed.
5. Use of the mangosteen extract of claim 1 in the replacement of antibiotic feed additives and feed additive raw materials.
6. Use of the mangosteen extract of claim 1 in growth-promoting feed additives and feed additive raw materials.
