Description

Technical Field

[0001] The invention relates to a plant essential oil-based hoof bath emulsion composition and a preparation method thereof, and belongs to the field of veterinary antibacterial disinfection. Background Art

[0002] Hoof diseases mainly include hoof warts, interdigital dermatitis, foot rot, and interdigital skin hyperplasia. It is a common surgical disease in animals, with the highest incidence in horses and cattle. It can cause draft animals to lose their labor force and significantly reduce milk production in dairy animals.

[0003] In order to effectively prevent and control hoof diseases, ranches often use hoof baths for prevention and treatment. The main principle is to kill the pathogens of hoof diseases, such as Treponema, Fusobacterium necroticum, and Bacillus tuberculosis, and to prevent and treat hoof diseases by curbing the source.

[0004] At present, traditional hoof baths on the market mainly include formalin (formaldehyde solution), copper sulfate, antibiotics and Chinese medicinal materials. For example, Chinese patent CN116115707A discloses a concentrated foam bath for preventing and treating cow hoof rot, which is made of the following components by mass fraction: 1-8% polyhexamethylene biguanide hydrochloride, 1-2% o-phthalaldehyde, 12-20% Chinese medicinal extract, 5-10% cooling agent, 5-10% foaming agent, 1-3% foam stabilizer. %, antifreeze 10-15%, pigment 1-3%, pH regulator 0.1-0.3%, the balance is purified water; Chinese patent CN118178530A discloses an ointment for treating cow foot rot, the ointment raw materials are as follows: matrine 2-10 parts by weight, total flavonoids of wolfsbane 8-20 parts by weight, zeuraminol 5-15 parts by weight, copper 1-5 parts by weight, chelated zinc 1-5 parts by weight, glycerol 0.5-3 parts by weight, Tween 80 0.5-3 weight parts, 2-5 weight parts of ichthyol, the copper is copper sulfate, and the chelated zinc is amino acid chelated zinc; although it has a good inhibitory effect on necrotic Fusobacterium and nodular Bacteroides, and has a good therapeutic effect on the treatment of cow foot rot; but there are many problems in the use process; for example, although formalin is cheap and effective, it requires an environment above 13°C and has a strong odor, which is harmful to the respiratory tract and skin of humans and animals; although chemical reagents such as copper sulfate and chelated zinc have good effects and little irritation, they can cause serious chemical pollutants such as heavy metals, are easy to be accidentally ingested and poisoned, and have environmental risks; the use of antibiotics to prevent and treat hoof diseases is very popular at home and abroad, but excessive use can lead to the development of drug resistance. Summary of the invention

[0005] [Technical issues]

[0006] Traditional hoof baths on the market mainly include formalin (formaldehyde solution), copper sulfate, antibiotics and Chinese medicinal materials. Formalin (formaldehyde solution) often causes damage to the respiratory tract and skin of humans and animals. Although chemical reagents such as copper sulfate and chelated zinc are effective and less irritating, they can cause serious chemical pollutants such as heavy metals, which can easily cause poisoning through accidental ingestion and pose environmental risks. Although the use of antibiotics to prevent and treat hoof diseases is very popular, excessive use can lead to drug resistance.

[0007] Based on this, the purpose of the present invention is to provide a plant essential oil-based hoof bath emulsion composition and a preparation method thereof. The emulsion composition product can effectively kill hoof disease-related pathogens, does not contain heavy metals, is environmentally friendly, is non-corrosive, harmless to humans and animals, is easily soluble, and is easy to operate; can effectively prevent and treat animal hoof diseases, and can be sprayed on the lesion site of the animal, has a good preventive and therapeutic effect, and has a broad market prospect.

[0115] Results Analysis

[0116] 1. In order to evaluate the preventive effect of plant essential oil-based hoof bath lotion on hoof disease, Fusobacterium nucleatum, a typical pathogen of hoof disease in dairy cows, was selected as a representative for bactericidal test. The mass percentage of culture medium components required by the strain is as follows: 1.5% tryptone, 0.5% soy peptone, 0.5% sodium chloride, culture conditions: 37°C, anaerobic environment (80% N2-10% CO2-10% H2). The control group was not added with hoof bath lotion, and the results are shown in Table 1.

[0117] Table 1 The killing effect of hoof bath lotion on Fusobacterium nucleatum

[0118]

[0119]

[0120] From the results in Table 1, it can be seen that the plant essential oil-based hoof bath lotion prepared by adding thymol, compounding or not compounding carvacrol and cinnamaldehyde has a good killing effect on the pathogen Fusobacterium nucleatum, indicating that it can effectively kill the pathogen of hoof disease Fusobacterium nucleatum.

[0121] When the amount of plant essential oil added is less than 10% (Comparative Example 1), the killing effect of the hoof bath lotion on Fusobacterium nucleatum is significantly weakened. When the amount of plant essential oil added is 24%, it cannot be mixed evenly during the preparation process, demulsification occurs, and no hoof bath lotion can be obtained.

[0122] When thymol was not used and other essential oils (F, G, H) were used, the killing effect of the hoof bath lotion on Fusobacterium nucleatum was significantly weakened, indicating that the plant essential oil-based hoof bath lotion formed by thymol has a better killing effect on Fusobacterium nucleatum.

[0123] When carvacrol and cinnamaldehyde were not used and other essential oils were used in combination with thymol (I, J, K), the killing effect of the hoof bath lotion on Fusobacterium nucleatum was significantly weakened, indicating that the effect of compounding other essential oils in the formula of plant essential oil-based hoof bath lotion was not as good as carvacrol and cinnamaldehyde.

[0124] 2. To verify the actual efficacy of plant essential oil-based hoof bath lotion in the prevention and treatment of animal hoof diseases, 300 dairy cows with hoof diseases were selected, and lameness was used as an indicator. They were observed once a week, and the score system was used. The higher the score, the more severe the lameness. A score of 3 or more was considered severe lameness, that is, severe hoof disease. Formalin was used as the control group, and the results are shown in Table 2:

[0125] Table 2 Actual test of hoof bath

[0126]

[0127]

[0128] The results in Table 2 show that after using the plant essential oil-based hoof bath lotions of Examples 1 to 4, the lameness rate of dairy cows was greatly reduced, and the scores were all lower than that of the formalin control group, indicating that the plant essential oil-based hoof bath lotion prepared by the present invention has a better effect on the prevention and treatment of hoof diseases.

[0129] In summary, the plant essential oil-based hoof bath lotion prepared by the present invention does not contain heavy metals and is environmentally friendly; it has no irritating odor, is non-corrosive, is harmless to humans and animals, and can effectively kill hoof disease-related pathogens, and can effectively prevent and treat animal hoof diseases.
