Background

At present, most of farms carry out swine immunity detection and epidemic disease diagnosis by a method of detecting antibodies and pathogens of epidemic diseases through blood, the stress of blood collection on animals is large, and sampling personnel consume time and labor and have certain dangerousness (particularly when boar sampling is carried out). Blood sampling cannot meet the requirements of large sample volume and frequent sampling for epidemic disease purification monitoring, and blood samples are not suitable for pathogen detection due to short time of a plurality of pathogenic bacteria (toxemia). Currently, the eradication and purification of swine plague is developed comprehensively, a large number of samples need to be monitored, and the requirements of different monitoring stages and monitoring items on detection samples are different.

The liquid sample is the mixed liquid of saliva and serum exudate in the oral cavity of a pig, has wide biological functions, can be used for antibody detection and pathogen detection by methods such as PCR and the like. The liquid sample can be used for detecting various pathogens which affect the health and economic benefits of swinery, such as foot-and-mouth disease virus, swine fever virus, influenza virus, porcine reproductive and respiratory syndrome virus, circovirus type 2 and the like. The sample collecting and monitoring technology has the characteristics of convenient sample collection, small stress on organisms, rich detectable content, relatively stable components in samples, low protein and lipid content and the like. Since the pigs raised in groups always share feeders, drinkers, living areas and the like, the sample collection does not cause spread of epidemic diseases. Sample testing has been used in some pig farms to replace the original tissue and blood sample testing.

At present, the collection of the liquid sample is mainly carried out by adopting the method of extracting the sample left after the pig chews the rope, the pig is full of curiosity and interest to the surrounding environment and likes chewing, the method is very favorable for the collection of the sample, when the sample is collected, the sample on the rope needs to be manually twisted out and then subpackaged in a simple self-sealing bag for temporary storage, and in the process, the sample pollution is easily caused, and the operation is troublesome.

How to solve the above technical problems is the subject faced by the present invention.
