Veterinary medicine for preventing and treating chicken bursal disease and its preparation method and application

Abstract

The invention discloses a veterinary medicine for preventing and treating chicken bursal disease and its preparation method and application. The veterinary medicine comprises the following components in parts by mass: 100-300 parts of astragalus, 100-300 parts of white peony, wheat 50-250 parts of winter, 50-200 parts of Epimedium, 50-200 parts of Ligustrum lucidum, 50-150 parts of Radix Isatidis, and 30-80 parts of freeze-dried fruit powder of Sorbus nigra. The preparation method of the veterinary drug is as follows: (1) weighing the traditional Chinese medicines except the freeze-dried fruit powder of Aronia nigricarpa according to the mass fraction, pulverizing them, adding enzymes for enzymolysis to obtain the enzymolysis solution; (2) ultrasonically extracting the enzymolysis solution , solid-liquid separation, adding water to the solid, ultrasonic extraction, filtering, to obtain the filtrate; centrifuging the filtrate while it is hot, to obtain the supernatant; (3) heating the supernatant, lyophilizing after vacuum concentration, pulverizing, and adding to it Add Sorbus nigra, mix well, and serve. Compared with the prior art, the present invention can effectively improve the activity of veterinary medicine by adding Aronia nigra at the end.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a veterinary medicine for preventing and treating chicken bursal disease, a preparation method and application thereof. Background technique [0002] The demand of the market has enabled the rapid development of animal husbandry. In order to promote the growth of animals, shorten the growth cycle of animals, and improve the economic benefits and production efficiency of farming, more and more feed additives have been developed and widely used in animal husbandry. German researchers added aspartic acid to sheep feed, which is a synthetic non-protein nitrogen substance, and found that the nitrogen content in sheep blood increased significantly. Some antibiotics are used as additives in animal feed to prevent livestock and poultry diseases to a certain extent, but long-term use leads to serious consequences, and the disadvantages are becoming more and more obvious. Since chemic...

Problems solved by technology

[0017] However, traditional Chinese veterinary medicine powder is often crushed (low-speed pulverized) in a conventional way in the prevention and treatment of poultry diseases. Because chickens have a short intestine, the passage time of drugs in the digestive tract is very short compared with livestock, and the digestion of cellulose Low capacity, the digestive enzymes in the digestive juice can only extract a small part of the active ingredients in the drug under the influence of the drug cell wall, the absorption and utilization rate of the drug is low, the dosage per unit weight is large, and the effect is slow, resulting in a lot of waste
