Embodiment

[0015] The present embodiment purifies the method for laying hens Salmonella, and this purifying method comprises the following steps:

[0016] (1) Selection of original grandparent chickens: select 2,200 sets of Hailan brown original grandparent chickens, conduct a general inspection on the 100-130-day-old hens among the original breed grandparent chickens, and re-examine after 30 days if the general inspection fails to meet the standard. 280-310 days of age for a second general inspection; if the detection rate is less than 0.1% for two consecutive times, random inspections will be performed every 3 months thereafter, and each random inspection should not be less than 20%, if the random inspection does not meet the standard, another general inspection is required; Cocks are checked once a month, and all antibody-positive chickens are eliminated; Among them, the test results of the grandparent cock are shown in Table 1, and the test results of the grandparent hen are shown in ...

Abstract

The invention relates to a method for purifying salmonella of laying hens. The purification method comprises the following steps that firstly, stock progenitor chickens are selected, and all antibody positive chickens are weeded out; secondly, parent chickens are bred, infectious disease sources are prevented in the breeding process, a conventional chicken salmonella vaccine is used for water drinking, finally, the bred parent chickens are detected, and all the antibody positive chickens are weeded out; thirdly, a chicken house needs to be thoroughly cleaned before hatching of commercial chickens, and the hatching environment needs to be disinfected strictly in the hatching process, wherein the hatching environment is disinfected once a week under the normal condition, disinfected twice a week in the case of diseases and not disinfected three days before and after immunization. The method has the advantages that the disease source of the salmonella of the laying hens can be effectively purified, and the purification degree of the laying hens can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of Salmonella purification, in particular to a method for purifying Salmonella in laying hens. Background technique [0002] Salmonella not only causes poultry infection, but also human bacterial infection, which in turn leads to food poisoning, acute gastroenteritis and other diseases. At present, the European Union, the United States, the United Kingdom, France, Japan, etc. stipulate that Salmonella in meat, eggs, and dairy livestock and poultry products must not be detected. China's first national standard for eggs - the National Standard for Pollution-Free Eggs was introduced in 2006. The new standard for pollution-free eggs is very strict, requiring that no salmonella, chloramphenicol, etc. be detected in eggs. [0003] About 70% of foodborne enteritis and poisonings are caused by Salmonella, whose cycle of infection is: an infected hen lays an infected egg, from which an infected chick hatches, which ...
