Problems solved by technology

At this time, it is necessary to use artificial insemination for soft-shelled turtles to increase the fertilization rate of soft-shelled turtles. Common insemination devices can inject multiple individuals at a time, which will inevitably lead to cross-infection and reduce the fertilization rate.

Embodiment 1

[0018] Such as Figures 1 to 2 As shown, an insemination device for softshell turtles includes a main body 1, an enlarged part 2, a first vas deferens 3, a second vas deferens 4 and a plunger 5, the main body 1 is provided with an insemination channel 11, so The plunger 5 is located in the insemination channel 11, and the rear end of the enlarged part 2 is provided with a shunt chamber 6 with a three-way function, and the shunt chamber 6 includes a first port 61, a second port 62 and The third port 63, the first port 61 is connected to the first vas deferens 3, the second port 62 is connected to the second vas deferens 4, the outer wall of the third port 63 is connected to the The inner wall of the insemination channel 11 is in contact, and the shunt chamber 6 is movably connected to the main body 1 .

[0019] The plunger 5 is used to push the enlarged part 2 out of the main body. The rear end of the expansion part 2 is provided with a shunt chamber 6, and the third port 63 ...

Embodiment 2

[0026] The main body 1 is provided with a snap ring 8 at the end far away from the enlarged part 2, and the use of the plunger is cancelled. Then inject the semen into the cloaca of the female Chinese soft-shelled turtle through the insemination gun. After the injection is completed, unscrew the main body by rotating to separate the enlarged part from the main body, so that the enlarged part remains in the cloaca. The other parts are the same as in Example 1. .

Abstract

The invention discloses a trionychidae animal semen delivery device. The trionychidae animal semen delivery device comprises a device body, an expanding unit, a first semen delivery pipe, a second semen delivery pipe and a plunger, wherein inside the device body is provided with a semen delivery channel, the rear end of the expanding unit is provided with a distribution chamber with a three-way function, the distribution chamber comprises a first orifice, a second orifice and a third orifice, the first orifice is connected with the first semen delivery pipe, the second orifice is connected with the second semen delivery pipe, the side wall of the third orifice is in contact with the inner wall of the semen delivery pipe, and the distribution chamber is movably connected with the device body. The trionychidae animal semen delivery device has the advantages that the expanding unit is used for expanding the cloaca of a female pelodiscus sinensis; along with further inward pushing of the plunger, the expanding unit can be expanded off the device body and then retained inside the cloaca of the female pelodiscus sinensis to serve as a plug for preventing sperm inside the cloaca from overflowing; every female individual correspond to one expanding unit to avoid cross infection among the female individuals and improve the fertility rate.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a stress-reducing semen collection device for softshell turtles. Background technique [0002] Animal reproduction is a key link in animal production and plays an important role in increasing the number and quality of animals. It is of great significance in the field of animal reproduction technology to study the regulation and improvement of animal reproductive performance and to explore the reproductive potential of animals. [0003] Under natural conditions, soft-shelled turtles grow slowly, with low egg production, fertilization rate, and hatching rate, and long incubation time. Therefore, in order to meet the current development needs of the soft-shelled turtle industry and improve the economic benefits of breeding, artificial breeding has become a key link to provide a large number of seedlings and ensure the sustainable development of the industry. At this time, it is nec...
