A device and method for preventing and treating dairy cow tuberculosis by drug intervention

Abstract

In the device for preventing and treating dairy cow tuberculosis provided by the present invention, an injection mechanism is provided on the fixing mechanism, and the injection mechanism includes a syringe, a limiting plate, a driving motor, a pullback spring and an injection spring, and a syringe is arranged inside the injection mechanism. There is a pull-back spring on the side, one end of the pull-back spring is connected to the middle of the injection mechanism, the other end of the pull-back spring is connected to the limit plate, a guide rail is set at the end of the syringe, a screw rod is set at the output end of the driving motor, and a slider is set on the screw rod. One end of the slider is arranged in the guide rail, a push rod is arranged in the syringe, an injection spring and a limit rod are arranged at the tail of the push rod, and the other end of the injection spring is connected with the guide rail. The use of the present invention makes it possible for the drug to intervene in scale farm intensive and high-density cattle herds for bovine tuberculosis, calves, the ratio of skin difference reduction in one course of treatment is 47%; young cattle have 76.7% positive cowhide difference reduction in one course of treatment ; After a course of treatment for adult cows, 42% of the positive cowhide differences are reduced, and the effect is more obvious.

Description

technical field [0001] The invention belongs to the field of animal husbandry quarantine, and in particular relates to a bovine tuberculosis prevention and quarantine device and its use. Background technique [0002] Cow tuberculosis is a zoonotic infectious disease caused by Mycobacterium tuberculosis. Mycobacterium tuberculosis is divided into three serotypes: human type, bovine type and avian type. The bovine type and human type can be transmitted to each other. In order to prevent bovine type Mycobacterium tuberculosis is transmitted to humans through milk, beef, cow respiratory tract, feces, etc. It is very important to control tuberculosis in dairy cows from the source. [0003] At present, the prevention and control method for dairy cow tuberculosis is mainly to quarantine dairy cow tuberculosis every year. According to the national regulations on the prevention and control of dairy cow tuberculosis, dairy cows are quarantined twice a year. The quarantine method is in...

Problems solved by technology

[0008] In view of the error in the PPD test and quarantine method in the prior art, it is difficult to control the prevalence of dairy cow tuberculosis only by quarantine-culling, and the difficulty of culling is large. There is no preventive measure for sub-healthy cows or threatened dairy cows, so that it develops into a Positive cows caused the technical problem that the dairy herd could not be thoroughly purified for a long time. The applicant provided a device and method of using drugs to prevent and treat tuberculosis in dairy cows. Dairy cows are subject to secondary quarantine, and the positive cattle that have been quarantined are culled, and on this basis, the threatened cows, suspicious cows, and sub-healthy cows are intervened with drugs

Use the intervention effect of drugs to control the spread of dairy cow tuberculosis, reduce the infection rate of dairy cows, further purify the cows, achieve the goal of controlling human tuberculosis from the source, and solve the problem of difficult drug application during drug intervention, no longer It is necessary to catch cattle every day for intramuscular injection one by one, which greatly reduces manpower, enables effective use of drug intervention programs, and has wide applicability in the field of agriculture and animal husbandry
