Medicament for preventing and controlling infectious bronchitis

Abstract

The invention discloses a medicine for preventing and curing the infectious bronchitis of chicken (IBV). The medicine is prepared by mixing the following Chinese herbal medicines in certain proportion: radix isatidis, pyrrosia leaf, double blossom, radix scutellariae, bulbus fritillariae cirrhosae, apricot, common clubmoss herb, ephedra, angelica dahurica, raw white alum, fructus aristolochiae, gypsum, rhizoma anemarrhenae, forsythia, fried radish seed, fried pepperweed seed, fried perilla-seed, mongolian snakegourd root, inula britannica chinensis, rhubarb, gardenia and raw liquorice. The materials are dried, separated from impurities, crushed, milled, mixed and then evenly stirred. During the clinical use, the powder is immersed in boiled hot water for 30 to 60 minutes, so that the effective drug ingredients are fully dissolved and separated out. The medicine is helpful for the internal absorption of the sick chicken. Meanwhile, the addition of a little bit of sugar and VC into the medicine liquid can improve the effect of the medicine. The medicine has high cure rate clinically, no adverse reaction, no hidden risk of drug residue and drug resistance. The invention has simple preparation and convenient usage and can be widely used in the chicken raising industry.

Description

Technical field: [0001] The invention belongs to the technical field of medicine and medical engineering, in particular to a medicine for preventing and treating chicken infectious bronchitis (IBV). Background technique: [0002] my country's large-scale chicken farming mostly adopts cage feeding and house feeding, especially in the brooding stage, when the density of chicken flocks is relatively high. In view of the physiological characteristics of chicks, the appropriate temperature (33-35°C in the first week, then lowered by 2-3°C per week) ℃) is the main condition to improve the survival rate of brooding, and the fresh air in the room is also indispensable. In brooding production practice, ventilation and heat preservation often contradict each other, and there is a phenomenon of heavy heat preservation and light ventilation, which can easily induce the occurrence of chicken infectious bronchitis (IBV), and the mortality rate of chicks can reach 25-40%, resulting in grea...

Problems solved by technology

In brooding production practice, ventilation and heat preservation often contradict each other, and there is a phenomenon of heavy heat preservation and light ventilation, which can easily induce the occurrence of chicken infectious bronchitis (IBV), and the mortality rate of chicks can reach 25-40%, resulting in great economic loss

At present, the drugs to prevent the disease are mainly corresponding vaccines, such as commercially available H120, H52 and other vaccines, which have a certain immune protection effect after correct immunization, greatly reducing the large-scale occurrence and prevalence of the disease, but in production practice Due to many problems such as imperfect immunization procedures or insufficient immunization doses, improper immunization methods, missed immunization or even unavoidable, the disease occurs locally and sporadically every year, especially in some rural areas where the amount of breeding is dominant. so so

In addition, the IBV virus has multiple serotypes, 10 have been confirmed, and there may be 18 serotypes. Moreover, there is a lack of or only partial cross-immunity between different types of strains, which shows that single-use vaccines can prevent the disease. Th
