The utility model discloses a culture dish for microbial cells, belongs to the technical field of culture dishes, and solves the problem that when an existing device is used for flora inoculation, a certain opening and closing angle is formed between a bottom box and a cover inconveniently with a single hand, and consequently strain lineation is inconvenient, the culture dish comprises a dish body and a dish cover, the dish cover is clamped to the upper portion of the dish body, and the dish cover is clamped to the lower portion of the dish body. A rotating assembly is arranged on the outer side of the dish body and the outer side of the dish cover and comprises a rotating ring, a lug plate, a threaded rod, a nut, a rotating rod and a connecting block, the rotating ring is rotationally arranged on the outer side of the dish body, and the positions of the dish body and the dish cover can be limited by arranging the rotating ring, the lug plate, the threaded rod, the nut, the rotating rod and the connecting block; the situation that the dish cover falls off from the dish body is avoided, the dish cover can incline with the rotating rod as the axis so that microbial cells can be conveniently inoculated into the dish body, the purpose that the dish body and the dish cover can conveniently form a movable opening and closing angle to facilitate inoculation is achieved, and use is easy and convenient.

The utility model discloses a kind of for yak breeding young cattle breeding device, it is related to young cattle breeding technical field, including drive assembly, the drive assembly is composed by drive mechanism and blocking mechanism.Just injection mechanism can reserve a large number of vaccine liquid for use, avoid the action of repeatedly pumping liquid when injecting, drive mechanism can control injection mechanism to realize the function of automatic pumping and injecting liquid, it is convenient to inoculate and inject operation to more young cattle vaccine, and blocking mechanism can adjust and control the pumping amount and injection amount of medicament when injection mechanism single injection, dose control accurate, when injecting vaccine to young cattle currently, still using traditional syringe to inject, when needing to inoculate and inject vaccine to more young cattle, it needs repeatedly pumping vaccine liquid and injection operation, very cumbersome, and pumping amount and injection amount each time need artificial visual judgment and control, the problem of poor accuracy.

The invention relates to the field of animal health. The present invention provides an attenuated infectious bronchitis virus (IBV). The attenuated infectious bronchitis virus can protect chickens from IBV infection.
