The invention relates to the technical field of veterinary devices, and discloses a veterinary sick pig manure inspection apparatus in a laboratory, including a casing. A baseplate is fixedly connected to a right side of the casing, and during sampling, squeezes a rubber ball to complete automatic sampling, and a degree of squeezing the rubber ball remains the same. Therefore, quantification is ensured every time a sample is taken. By eccentric rotation of a third rotating rod, stirring is more sufficient relative to ordinary vertical rotation, and a manual stirring operation is not required,thereby improving work efficiency. Through a function of a support plate, when a beaker is used for sampling, displacement of the support plate is driven to change, thereby linking a subsequent mechanical movement, increasing linkage of the entire apparatus, and having a simpler operation. Through design of a baffle, the casing is kept in a sealed state in a stirring process, to prevent an odor ofa pig manure sample from affecting an experimental environment, and the baffle can be automatically opened during sampling, thereby increasing practicality of the entire apparatus.
