Veterinary medicine for animal's epidemic disease and its preparation process and application

Abstract

The present invention relates to veterinary medicine for preventing and treating animal's epidemic disease. The veterinary medicine is prepared with triperygium wilfordii, hairystalk loosestrife herb, aniseed, forsythia, clove and other materials, and through alcohol solution extraction, distillation of the extract liquid, adding beta-cyclodestrin and starch through stirring and spray drying. The veterinary medicine can inhibit flu virus, prevent diseases and kill pathogenic microbes, and is added into farm animal feed to prevent and treat diseases.

Description

technical field

[0001] The invention relates to veterinary medicine, in particular to a medicine for preventing and treating livestock and poultry epidemic diseases, as well as a preparation method and application of the medicine. The invention is particularly suitable for avian influenza. Background technique

[0002] Epidemic diseases of livestock and poultry, such as bronchitis, laryngotracheitis, and influenza, are common and frequently-occurring diseases of livestock and poultry. Most of them are caused by climate change or poor feeding management, which lead to the decline of livestock and poultry physique and the invasion of cold viruses. Such diseases can usually cause large-scale epidemics through airborne or contact infection. Due to the large number of breeding and the concentration of livestock and poultry in general farms, once such a disease occurs, it can affect the entire livestock and poultry group within a few days. If it cannot be controlled and treated i...

Examples

Embodiment 1

[0027] Take selected and cleaned Tripterygium wilfordii 26Kg, Pai Caoxiang 21Kg, star anise 20Kg, forsythia 16Kg, clove 17Kg, grind into 60 mesh fine powder, put into extraction tank, add 70% ethanol 351kg, 70 ℃ preheat for 40min , heat up to 90°C, heat and reflux for extraction for 6 hours, filter the extract, send the filtrate into a distillation pot, distill under reduced pressure and recover ethanol to obtain 33Kg of concentrated extract. 1Kg beta-cyclodextrin and 80Kg starch are added to the concentrated extract, mixed and stirred evenly, and the product is obtained after spray drying.

[0028] The product of this embodiment is used as a livestock feed additive, and the addition amount is 0.5% of the weight of the livestock feed.

Embodiment 2

[0030] Take selected and cleaned Tripterygium wilfordii 22Kg, Pai Caoxiang 25Kg, star anise 20Kg, forsythia 16Kg, clove 17Kg, grind into 80 mesh fine powder, put into extraction tank, add 60% ethanol 360kg, preheat at 60°C for 60min , heat up to 85°C, heat and reflux for extraction for 6 hours, filter the extract, send the filtrate into a distillation pot, distill under reduced pressure and recover ethanol to obtain 31Kg of concentrated extract. Add 0.8Kg β-cyclodextrin and 65Kg starch into the concentrated extract, mix and stir evenly, and obtain the product after spray drying.

[0031] The product of this embodiment is used as a livestock feed additive, and the addition amount is 0.5% of the weight of the livestock feed.

Embodiment 3

[0033] Take selected and cleaned tripterygium wilfordii 20Kg, Pai Caoxiang 27Kg, star anise 20Kg, forsythia 16Kg, clove 17Kg, grind into 50-mesh fine powder, put into extraction tank, add 95% ethanol 300kg, preheat at 60°C for 60min , heat up to 85°C, heat and reflux for extraction for 6 hours, filter the extract, send the filtrate into a distillation pot, distill under reduced pressure and recover ethanol to obtain 35Kg of concentrated extract. 1.2Kg beta-cyclodextrin and 80Kg starch are added to the concentrated extract, mixed and stirred evenly, and the product is obtained after spray drying.

[0034] The product of this embodiment is used as a poultry feed additive, and the addition amount is 0.3% of the poultry feed weight.
