Methods and compositions for synchronizing the time of insemination in swine are described. More particularly, methods are described for synchronizing the time of insemination by administration of a composition comprising a hormone, wherein the swine is inseminated only one time after administration of the hormone, and wherein there is no heat detection.

The present invention relates in general to the improved containment of biological fluids. In particular, a method and apparatus for collection and preservation of fluid samples in accordance with the present invention results in collection of semen having improved viability both at the time of collection and after storage. The disclosed methods and apparatuses methods support a wide variety of applications for containment of biological fluids related to human and veterinary medicine including, but not limited to, human reproductive medicine and animal husbandry.

There are provided a microscopic mirror imaging device, a system and a method for calibrating a posture of a microneedle. The microscopic mirror imaging device includes a motion actuator, a mirror image former support and a mirror image former. The motion actuator is fixedly mounted on a microscope stage. One end of the mirror image former support is connected to the motion actuator. The mirror image former includes a plane mirror mounted on the other end of the mirror image former support. An angle formed between a mirror surface of the plane mirror and a horizontal plane of the microscope stage is equal to 45°, and an angle formed between the mirror surface of the plane mirror and a coronal plane of the microscope stage is equal to 45°.

The present invention provides a device and system for monitoring the accuracy of procedures in the course of the performance of a task, the task comprising at least one procedure to be performed, the device comprising: an input interface for receiving input data relating to the procedures; a data store for storing data relating to the procedures; a processor for: comparing the input data with the stored data; and generating a comparison result indicating the result of that comparison; and an output interface for outputting the comparison result.

An artificial propagation method of Sinocyclocheilus rhinocerous, comprising placing female and male parent fish in a sterilized culture container in which a black cave simulant is placed in advance, strictly controlling the environmental parameters of the parent fish culture. The method realizes natural spawning and sperm production of S. rhinocerous under artificial conditions without using oxytocin. There is no oxytocin used in the artificial propagation, thus not only obtaining a higher fertilization rate and incubating rate, but also reducing the aquaculture cost. The operation is simpler and faster. At the same time, different feeds are fed in different growth stages according to the different growth characteristics of each stage of S. rhinocerous fry, thereby increasing the survival rate and reducing the deformity rate of fries. Therefore, the method provided by the present disclosure realizes efficient artificial propagation method of S. rhinocerous.

A doll shaped as a female canine comprising a body coupled to a plurality of adjustable limbs and having a rear hole, a tubular insert that is removable and sterilizable, wherein the rear hole is a cylindrical hollow portion designed as a tubular channel to receive the tubular insert with a plastic lining that collects the semen flow into the hollow body of the tubular insert and after using the tubular insert is removed and disinfected for the next use.
