Composition for treating hen egg-drop syndrome

Abstract

The invention belongs to the field of veterinary medicines, and specifically discloses a composition for treating a hen egg-drop syndrome. The composition comprises the following components in parts by weight: 12-15 parts of senecio scandens, 8-11 parts of emilia sonchifolia, 4-7 parts of blackberrykiky rhizome, 4-7 parts of licorice, 2-3 parts of myrsinaceae Ardisia elegans and 0.1 part of herba aconiti. The laying rate of hens suffering from the egg-drop syndrome can reach more than 90% of that of normal hens.

Description

technical field [0001] The invention relates to the field of veterinary medicine, in particular to a composition for treating egg drop syndrome of laying hens. Background technique [0002] Egg Drop Syndrome is an infectious disease caused by avian adenovirus group III that can reduce the egg production rate of chickens. Sick chickens are characterized by decreased egg production, soft-shell eggs, shellless, brown or deformed abnormal eggs, and other aspects are normal. Epidemiology: Laying hens aged 25-35 weeks can develop the disease, mainly through egg-transmitted infection, and horizontal transmission and spread in the same cluster, flat breeding is faster than cage breeding. At first, the color of colored eggs disappears, and then thin-shelled, soft-shelled, or shellless eggs appear. Thin-shelled eggs often have rough shells, like sandpaper. In a few weeks, egg production will drop significantly. Eggs may be reduced by 40%, and the onset generally lasts 4-10 weeks. D...
