Traditional Chinese veterinary medicine (Natural Herb Extract) has the advantages of wide-ranging functions, two-way regulation, few side effects, low residue, no drug resistance, etc. It also has the characteristics of wide resources, easy planting and easy harvesting, simple production, low cost, and long-lasting effects. A gem of medical cultural heritage.
In order to enable the people to eat safe food and protect their health, my country has launched the "Pollution-Free Food Action Plan."
Units and individuals involved in the production and processing of livestock products must pass the certification of pollution-free livestock products to gain access to the sales market. At present, various provinces and cities across the country have successively implemented plans for green livestock and poultry products.
Promulgated production specifications for pollution-free animal products and green animal products, and guidelines for the use of veterinary drugs. The research and development of Chinese veterinary drugs and feed additives of Chinese veterinary drugs is precisely adapted to the national policy. In addition, it is also the need of an export-oriented strategy for animal products, opening up the international market, and participating in international market competition.
In recent years, many countries have adopted stricter technical measures to restrict the entry of products from other countries into their own markets. The usual measure in the animal husbandry industry is to implement "green barriers", that is, to set up barriers to keep foreign livestock products out of the country by borrowing that the import of livestock products involves consumer safety. At present, the "green barrier" measures implemented in some countries have formed an export barrier for my country's livestock and poultry products, and have become an important factor restricting the development of my country's livestock industry.
Some poultry products in my country have been rejected, detained, terminated contracts and even sealed customs because their technical indicators such as pathogens and veterinary drug residues exceed those of the European Union and major importing countries such as Japan. The EU prohibits the use of spiramycin, bacitracin zinc, virginithromycin and tylosin in chicken production. At the same time, it vigorously develops natural medicines, immunomodulators and other green natural plants as alternative products, and promotes them in breeding production.
Chinese veterinary drugs in our country have become the first choice for alternative chemical drugs and antibacterial drugs due to their profound theoretical foundation and the characteristics of low toxicity, no drug residues and no drug resistance.
Chinese herbal medicine and its additives have the following remarkable characteristics.
1.1. The naturalness is taken from the naturalness. After natural processing, the natural structure and activity are maintained. At the same time, they are a kind of food with special functions, natural products digested and absorbed by humans and animals.
1.2. Multifunctionality Each Chinese medicine is an organic complex with multiple structural components (some contain tens to hundreds of components), which can produce multiple effects, and each component can have a complex effect, such as hawthorn. There are more than 70 kinds of ingredients, which can help digestion and absorption, cure liver diseases, strengthen the heart, and replenish blood.
1.3. Non-residual toxicity Chinese herbal medicine is a kind of food with special effects and natural organic matter retained by humans and animals for a long time. Humans and animals have enzymes that make them catabolize, so they can be absorbed, decomposed and excreted normally. "It is a three-point poison" Chinese medicine is no exception, but compared with western medicine, Chinese medicine has lower toxicity and is relatively safe. In addition, Chinese herbal medicine can also be naturally processed to detoxify, and be matched with prescriptions, and detoxified by killing and fearing each other.
1.4. It will not cause microorganisms to produce parasites such as drug-resistant bacteria and viruses. They are a class of low-level organisms with simple structures, and they are also the most adaptable organisms in nature. They have powerful variant structures and metabolic methods. However, most of the antimicrobial chemicals used today have a single structure and pathway of action, and are within the mutability of microorganisms. Therefore, after multiple exposures, microorganisms develop resistance, and the resistance genes are inherited to produce new resistance. The population makes the human beings difficult to prevent and control diseases.
Chinese herbal medicine uses multi-function and modulates all anti-disease factors of the body, that is, non-specific immune factors (leukocyte phagocytosis, lysosome, enzyme, bactericide, interferon, complement, etc.) to kill microorganisms in all directions, making them unable to adapt to mutations , So it cannot produce resistance. The non-specific immune effects of the above-mentioned Chinese herbal medicines suggest that when screening the antimicrobial effects of traditional Chinese medicines, the in vitro antibacterial effect cannot be used as the only criterion.
1.5. Two-way regulation and adaptation. Two-way regulation refers to the effect that a single traditional Chinese medicine can adjust different states of the same organs (physiology and pathology, excitement and inhibition), that is, it can be adjusted to a normal state when it is hyperactive, and It can enhance its function to normal two-way regulation during inhibition. For example, Angelica sinensis contains two components that excite and inhibit uterine muscle, which can regulate uterine muscle in both directions. In addition, Ophiopogon japonicus, Shengdi, Scrophulariaceae, etc. have a two-way regulating effect.
Adaptation effect refers to the role of traditional Chinese medicine that can adjust the physiological dysfunction of animals in harsh environments, and make them move in the direction that is beneficial to the body and continuously enhance the adaptive ability, such as acanthopanax senticosus, ginseng, astragalus, codonopsis , Licorice, etc. have the effect of adaptation. They can be used to prevent stress and prevent stress syndrome.
1.6 Hormone-like action Hormone is a kind of trace biologically active substance that adjusts animal balance. In animal husbandry production, exogenous hormones have been used to increase fecundity and weight gain and fattening, with good results. However, it has been eliminated or banned because of its residual toxic and side effects and affecting the human health of eating such animal products.
Chinese herbal medicine itself is not a hormone, but it can play a hormone-like effect and has no residual toxic side effects of exogenous hormones. Therefore, it is highly valued. Chinese herbal medicines with hormone-like effects, such as licorice, xiangfu, cranium, epimedium, evodia, Buffalo horn, medlar, etc.
The animal husbandry industry is developing in the direction of intensive and large-scale. The breeds of livestock and poultry are constantly increasing, and the types, scope and causes of livestock and poultry diseases have also changed greatly, especially the current epidemic is characterized by atypical viral diseases and various viruses. There are more and more diseases, chronic diseases and foreign diseases caused by bacteria, bacteria and bacteria mixed infections and secondary infections, causing great losses to the animal husbandry industry.
In this case, the addition of a large number of preventive drugs such as chemicals and antibiotics has even reached the increase in drug resistance caused by abuse. The result is that the drug residues are seriously exceeded, which does not meet the national pollution-free animal products and export animal products quality requirements.
The advantages of Chinese veterinary drugs are low toxicity, no drug residues, and no drug resistance. The holistic thought given when medication emphasizes the treatment based on syndrome differentiation, strengthening the righteousness and eliminating evils, balancing Yin and Yang, focusing on the root cause, and the development trend of its application:
2.1. Chinese herbal medicines are used to prevent and treat viral diseases in livestock and poultry. Chinese herbal medicines are generally used to clear away heat, detoxify, strengthen the body and eliminate evils. Chinese herbal medicines containing antiviral active factors such as Daqingye, Isatis root, honeysuckle, forsythia, shegan, and burdock are commonly used. Seed, Coptis, Andrographis, Scutellaria, Phellodendron, Polygonum cuspidatum, Wild Chrysanthemum, Indigo Naturalis, Parsnips, Dandelion, Houttuynia cordata, etc. to clear away heat and detoxify, and are matched with Chinese herbal medicines that enhance the body’s immune function such as Epimedium, Codonopsis, Astragalus, Atractylodes, Chinese yam, licorice, poria, angelica, acanthopanax senticosus, etc. are used to strengthen vitality and blood.
There are also a few Chinese herbal medicines such as astragalus which can both anti-virus and improve the immunity of the body. It enhances the phagocytic activity of mononuclear macrophages, releases immunologically active substances to somatic cells and natural killer cells, and induces interferons and interleukins. It has a variety of physiological activities.
2.2. Chinese herbal medicine is used to prevent and treat bacterial diseases of livestock and poultry. On the one hand, the antibacterial effect of Chinese herbal medicine is to act on microorganisms through Chinese herbal medicine containing antibacterial substances such as berberine, allicin, and houttuyfonate. On the other hand, it kills microorganisms by mobilizing the body and the immune system. Hu Gongzheng and others used Chinese herbal medicine Sophora flavescens, Dandelion, Andrographis paniculata to treat chicks artificially infected with E. coli with 0.75% mixture. The average cure rate was 95.3%, and the infection without drugs was 26.7%.
Wang Junhong and other studies have shown that Codonopsis pilosula has obvious inhibitory or killing effects on Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Leptospira. Gao Weiwei and other studies have shown that the water extract and alcohol extract of Forsythia suspensa, the alcohol extract of Sophora flavescens, and the water extract of Pulsatilla have a strong inhibitory effect on Salmonella pullorum and Salmonella typhimurium.
2.3. Chinese herbal medicines are used to prevent and control parasitic diseases of livestock and poultry. Many Chinese herbal medicines have anti-parasitic effects. Especially the application of Chinese herbal medicines to control coccidiosis is also a major development direction to be considered in the future. At present, coccidiosis, like viral diseases, has become another scourge of the aquaculture industry.
People use Chinese herbal medicine to prevent and treat coccidiosis, which has shown certain effect and good momentum. There are individual compound preparations that are more effective than diclazuril, and, like other diseases such as viral diseases, can prevent and cure veterinary drug residues and drug resistance, so they also have good development prospects.
2.4. Chinese herbal medicines are used in livestock and poultry immunomodulators and immune adjuvants. Modern research has shown that Chinese herbal medicines can regulate the body's nerves, body fluids and cellular molecular levels in all directions, thereby playing a regulatory role. The righteousness of Chinese veterinary medicine is actually the body's immune function.
Since many Chinese medicines and prescriptions contain glycosides, alkaloids, polysaccharides, organic sugars, volatile oils and other immunologically active substances, it can activate the body's cellular and humoral immune system, improve the body's ability to resist diseases, and achieve the purpose of preventing and curing diseases.
Recipes that have been proved to have this function include strengthening the body and strengthening the body, nourishing yang, nourishing yin, promoting blood circulation and removing blood stasis, clearing away heat and detoxification, astringent, and hemostasis. Among these prescriptions, some can promote the development of immune organs, some can enhance the activity of immune cells, and some can regulate the body's cellular immune function and humoral immune function.
Immune adjuvants, also known as immune enhancers, are substances that non-specifically change or enhance the body's specific immune response to the antigen or antigens injected into animals at the same time. It is often accompanied by a variety of vaccine effects, which can reduce the production cost of livestock and poultry vaccines and improve the protection of vaccines.
At present, domestic and foreign research on Chinese herbal immunological adjuvants has just started and some progress has been made. For example, some people in China use astragalus polysaccharide to enhance the serum antibody titer of Marek's vaccine; use corn pollen polysaccharide to enhance the immunity of swine fever attenuated vaccine; Liaoning Yikang Biological Products Factory uses Chinese herbal medicine to make vaccine adjuvants to study the immunity of E. coli vaccine Effect, the test results show that the immune effect of Chinese herbal medicine adjuvant chicken E. coli is better than the vaccine effect of oil and aluminum gel adjuvant.
Solvay Company of the United States used aloe extract acetyl mannan as an adjuvant for chicken Marek vaccine, showing a good adjuvant effect. Therefore, Chinese herbal immune enhancers have become a major trend in future research and development.
2.5. Chinese herbal medicines are used in livestock and poultry feed additives. Chinese herbal medicine feed additives are developed in the production of modern and intensive aquaculture production with the advantages of Chinese medicine for disease prevention and health care, promotion of production performance, and low toxic and side effects.
In recent years, its research and application have received extensive attention, and great progress has been made. From livestock and poultry, aquatic products to bees and silkworms and other animals, from single prescriptions to compound prescriptions, from gaining weight and accelerating growth to preventing various diseases, There are developments in all aspects.
In China, Zhejiang Agricultural University has developed sugar terpenoid feed additives, which can enhance animal immunity, antibacterial and antiviral functions; abroad, Dutch researchers prepare oregano oil premix with volatile oil extracted from oregano grass. Other livestock and poultry have the effect of antibacterial, stopping diarrhea and promoting growth.
Not long ago, a commercial pig heat stress Chinese herbal additive was developed in China, which has the functions of appetizing and strengthening the spleen, clearing away heat and detoxification, and reducing heat and summer heat. Adding to the diet can reduce the impact of high humidity and heat on pig performance. Experiments show that the additive in summer can increase the weight of test pigs by 8.7% and increase the feed utilization rate by 12.4%.
China is the first country to use Chinese herbal medicines in livestock and poultry production. We have precious Chinese veterinary theories and abundant Chinese herbal medicine resources. We should seize the opportunity and make full use of our resources and technological advantages to develop animal husbandry with Chinese characteristics.
2.6. Chinese herbal medicines are used in dogs and cats and aquaculture. With the development of the pet industry, pet hospitals have emerged throughout the country. The demand for medicines mainly for dogs and cats will also increase. Foreign countries have accounted for 34% of animal medicine. %, while most of the medicines for dogs and cats in my country are western medicines for humans, there are very few Chinese medicines in clinical application, and there is no animal prescriptions for dogs and cats. The veterinary medicine market can see such as Shuanghuanglian oral liquid, Bupleurum injection, fishy Herbal injection and other Chinese medicines are used concurrently. Therefore, Chinese herbal medicine preparations for dogs and cats have a lot of room for development and promising prospects.
Aquaculture medicine started late and management is weak, but its development space is large and it accounts for a large share in the veterinary medicine market. However, there are few Chinese herbal medicines, which is also the direction of Chinese herbal medicine research and development.
