Problems solved by technology

[0004] Although vaccinated, there is no guarantee of 100% immunity
Unsuccessful laying hens are still likely to suffer from egg drop syndrome, affecting egg production
Although the laying hen treasure that is often used to treat egg drop syndrome has certain effects, the egg production rate can only reach about 70% of normal laying hens

Embodiment

[0018] Embodiment: Select 450 layer hens suffering from egg drop syndrome of the same age and divide them into three groups, namely blank group, control group and experimental group. Each group has 3 repetitions, and each repetition has 50 sick chickens. 150 normal laying hens of the same age were selected as the standard group, and the standard group was set up with 3 replicates, each with 50 chickens. The experiment was carried out for 5 days, and the egg production rate was counted. Except for the following processing differences, other conditions are the same as conventional techniques.

[0019] Standard group: feed only, no medicine added to the feed.

[0020] Blank group: only feed was fed, and no medicine was added to the feed.

[0021] Control group: add layer chicken treasure in the feed (the mass ratio of feed and layer chicken treasure is 500:1), the formula of layer chicken treasure is: calculate according to weight parts, including 1 part of Codonopsis pilosula,...

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...
