Description

Technical Field

[0001] The invention relates to the technical field of artificial insemination in animal husbandry, in particular to a fake alpaca for semen collection. Background Art

[0002] Alpacas are native to South America. Their wool is known as "soft gold" for its fineness, strength, elasticity, and non-allergenic properties. It holds great economic value. However, alpaca populations are expanding slowly, relying primarily on natural mating or assisted natural mating. The promotion of artificial insemination technology still faces numerous challenges:

[0003] 1. Limitations of existing semen collection methods

[0004] Currently, alpaca semen collection mainly adopts condom method, electrical stimulation method and false vagina method, but all of them have obvious shortcomings:

[0005] Condom method: It is easy to contaminate semen, has low collection efficiency, and may interfere with the natural mating behavior of alpacas;

[0006] Electrical stimulation method: The operation is complicated and can easily cause stress in animals, affecting semen quality;

[0007] Traditional artificial vagina method: Although widely used in cattle, sheep and other livestock, the unique reproductive physiological characteristics of alpacas make them less suitable.

[0008] Lying mating: Alpacas lie down during mating, and traditional artificial vaginas are difficult to stabilize;

[0009] Long mating time: on average, it lasts 20-25 minutes, and ordinary pseudovaginas cannot maintain constant temperature and pressure;

[0010] Deep ejaculation: The alpaca penis needs to pass through the cervix and ejaculate in the uterine horn. Traditional artificial vagina cannot simulate this physiological structure, resulting in a low semen collection rate.

[0011] 2. Technical defects of artificial vagina and artificial uterus

[0012] In the practice of alpaca artificial insemination, the existing equipment has the following problems:

[0013] The fake alpaca has low simulation: the appearance, smell and touch are not simulated enough, and the male alpaca is not willing to mount;

[0014] The temperature control of the artificial vagina is unstable: it relies on artificial water injection to adjust the temperature, which is prone to local overheating or overcooling, affecting sperm motility;

[0015] Unreasonable structural design: It is difficult to adjust the pressure inside the traditional artificial vagina, which cannot meet the long-term mating needs of alpacas, resulting in semen collection failure or deterioration in semen quality.

[0016] 3. Constraints on technology promotion

[0017] Despite years of research on alpaca semen collection technology abroad, a standardized approach has yet to be established. In China, the lack of adaptable semen collection equipment has limited the application of artificial insemination technology, severely hampering the large-scale development of the alpaca farming industry.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] The purpose of the present invention is to provide a fake alpaca for semen collection to solve the problems existing in the prior art. The angle of the fake vagina can be conveniently adjusted using an adjustment hole, and the angle and position of the fake vagina can be limited by a limiting structure. At the same time, the surface of the fake alpaca body is covered with fur, which can simulate the body structure and characteristics of a real female alpaca and improve the semen collection effect.

[0052] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] like Figures 1 to 12 As shown, the present invention provides a dummy for alpaca semen collection, comprising a dummy body 1, a false vagina 2, a limiting structure, and fur. A first placement groove 11 is provided at the tail of the dummy body 1. The first placement groove 11 extends from the tail of the dummy body 1 to the head. The first placement groove 11 may extend only partially, or may extend through the head to provide sufficient space for the installation of the false vagina 2. An adjustment hole 13 is provided on one or both sides of the tail of the dummy body 1. The adjustment hole 13 is connected to the first placement groove 11. The adjustment hole 13 allows hands or tools to enter so as to contact the false vagina 2 in the first placement groove 11. The false vagina 2 is installed in the first placement groove 11, and the adjustment hole 13 is used to adjust the angle of the false vagina 2. The limiting structure is used to limit the angle and position of the false vagina 2. The limiting structure can be in the form of a pin, a block, or other structure. The fur covers the surface of the dummy body 1 to simulate the touch, appearance, and smell of a female alpaca.

[0054] The present invention provides a first placement groove 11 and an adjustment hole 13 on the fake alpaca body 1. The fake vagina 2 can be placed in the first placement groove 11, and the adjustment hole 13 can conveniently adjust the angle of the fake vagina 2. It also includes a limiting structure, which can limit the angle and position of the fake vagina 2. That is, after adjusting the angle of the fake vagina 2 through the adjustment hole 13, the limiting structure is used to limit the angle and position of the fake vagina 2 so that the position of the fake vagina 2 meets the requirements. At the same time, the surface of the fake alpaca body 1 is covered with fur to simulate the touch, appearance and smell of a female alpaca, so that the fake alpaca of the present invention can simulate the body structure and characteristics of a real female alpaca, attract male alpacas to mount, shorten the semen collection time, and improve the semen collection efficiency.

[0055] In one embodiment, a second placement groove 12 is provided on both sides of the artificial animal body 1 near the head. The second placement groove 12 extends from the top end to the bottom end of the artificial animal body 1. The second placement groove 12 can be set to an arc shape. The front legs of the male alpaca can be placed through the second placement groove 12, thereby improving the comfort of the male alpaca during semen collection, thereby improving the semen collection effect.

[0056] In one embodiment, the fake animal body 1 is made of wood, and the top of the tail of the fake animal body 1 is polished smooth to simulate the tail of a female alpaca, thereby improving the comfort of a male alpaca during semen collection and thereby improving the semen collection effect.

[0057] In one embodiment, the limiting structure includes limiting pins 5. Based on the principle that two points define a straight line, there are at least two limiting pins 5. Two or more limiting pins 5 cooperate to define the position of the artificial vagina 2. The tail portion of the artificial platform animal body 1 is provided with multiple through-holes 14 on one side or on both sides. The limiting pins 5 can be inserted into the through-holes 14. When through-holes 14 are provided on one side, the tail end of the limiting pin 5 can be inserted into the opposite wood for fixation. When through-holes 14 are provided on both sides, the positions of the through-holes 14 can be aligned so that the limiting pin 5 can simultaneously penetrate the through-holes 14 on both sides for fixation. By inserting limiting pins 5 into different through-holes 14, the angle and position of the artificial vagina 2 are limited.

[0058] In one embodiment, when designing the artificial vaginal body 1, the body length, back height, abdominal width, and hip height of different individual ewe alpacas when lying down are measured, and the average values ​​of each part are calculated. Solid wood is carefully polished to a smooth, free-standing surface. The middle and lower portions are hollowed out, and the ends are opened to form a first placement slot 11 for accommodating and securing the artificial vagina 2. In this example, the artificial vaginal body 1 is 82 cm long, 30 cm wide at the front, and 35 cm high. From 27 cm to the top, it is polished into an arc shape with an inner diameter of 18 cm high and 11 cm wide. The tail end is 20 cm high and 20 cm wide. The top of the tail end is polished to simulate the tail of an ewe alpaca. A square hole 13 is opened in the middle and lower side of the side, serving as an adjustment hole 13. Adjustment hole 13 is 10 cm long and 10 cm wide, used to adjust the angle of the artificial vagina 2. Adjustment hole 13 is 25 cm from the tail and 5 cm from the bottom. Arc-shaped notches are opened on the left and right sides of the top as second placement slots 12. The second placement slots 12 serve as sheep leg placement slots, providing a suitable position for the front legs of the male alpaca, simulating the natural mating environment of alpacas. Several holes are opened on the side of the tail end as through holes 14. The artificial vagina 2 is fixed with 16 cm long nails and the angle and position of the artificial vagina 2 are adjusted according to the size of the male alpaca and the position of the penis in the lying position by inserting different through holes 14. The exterior of the artificial livestock body 1 is fitted with the fur of the female alpaca, and the outer covering is 3 cm thick. It is fixed to the surface of the artificial livestock body 1 with long nails and gaskets to simulate the real touch, appearance and smell, and induce the male alpaca to climb.

[0059] In one embodiment, the artificial vagina 2 comprises a main body 21 and an outer shell 22 wrapped around the main body 21. The main body 21 comprises a tube 211 and an inner tube 212. The tube 211 is made of a metal material such as iron or aluminum, while the inner tube 212 is made of a flexible material such as rubber or plastic. The inner tube 212 comprises an interlayer 2121, which is a closed space. The tube 211 is provided with a water injection and pressure valve, which is connected to the interlayer 2121. By connecting the water injection and pressure valve to a water source, water can be injected into the interlayer 2121 of the inner tube 212, causing the central cavity of the inner tube 212 to shrink inward, simulating a vaginal structure. The tube 211 is connected to a first temperature control device, which maintains the artificial vagina 2 at a suitable temperature. The inner tube 212 is connected to a semen collection device, which is connected to the central cavity of the inner tube 212 and can collect semen.

[0060] In one embodiment, the first temperature control device includes a heating resistor wire wrapped around the tube 211. The heating resistor wire is wrapped with insulation material. The heating resistor wire heats the tube 211, transferring heat to the water inside and the inner tube 212, thereby controlling the temperature of the prosthetic vagina 2. The insulation material prevents heat dissipation and maintains the prosthetic vagina 2 within a suitable temperature range. To secure the insulation material, tape can be wrapped around the outside of the tube 211. A thermocouple is also included, located between the tube 211 and the insulation material, or between the inner tube 212 and the tube 211. The thermocouple can monitor the temperature of the prosthetic vagina 2. When the temperature exceeds a threshold, heating is stopped or the heating power is reduced. When the temperature falls below the threshold, heating is resumed or the heating power is increased.

[0061] In one embodiment, if Figure 10 As shown, a limiting portion 222 is provided at the end of the shell 22. The limiting portion 222 can be a metal block welded to the shell 22. When the limiting pins 5 are used to limit the position of the artificial vagina 2, one of the limiting pins 5 is clamped between the limiting portion 222 and the shell 22 to limit the height of the artificial vagina 2 and form a rotation support for the artificial vagina 2. At the same time, since the artificial vagina 2 is placed at an angle, the above-mentioned limiting pins 5 can be used to limit the forward and backward movement of the artificial vagina 2. Of course, the limiting portion 222 can be set to a ring shape, and inserting the limiting pin 5 into the ring-shaped limiting portion 222 can also play a limiting role. The other limiting pin 5 is used to limit the deflection angle of the artificial vagina 2, so that at least two limiting pins 5 are used to cooperate to achieve the limitation of the angle and position of the artificial vagina 2.

[0062] In one embodiment, if Figure 7As shown, the semen collection device includes a detachably connected semen collection cup 3 and a semen collection tube 4. The semen collection cup 3 is open at both ends, with one end connected to the inner tube 212 and the other to the semen collection tube 4. Alpaca semen flows through the semen collection cup 3 and into the semen collection tube 4 for collection. The semen collection tube 4 can be a small test tube. The semen collection cup 3 can be tapered, with the end connected to the inner tube 212 having a larger diameter and the end connected to the semen collection tube 4 having a smaller diameter. This facilitates collection of alpaca semen into the relatively smaller semen collection tube 4. The semen collection cup 3 and semen collection tube 4 are detachable, facilitating cleaning and disinfection. The artificial animal body 1 and artificial vagina 2 have a simple structure, making maintenance easy, reducing operating costs, and promoting widespread application.

[0063] In one embodiment, if Figure 11 As shown, the shell 22 includes two half shells 221 separated along the axial direction. The two half shells 221 are hingedly connected and provided with a locking structure 223. The half shells 221 can be locked by the locking structure 223 to connect into an integral shell 22.

[0064] In one embodiment, a second temperature control device is also included, connected to the semen collection device. The structure of the second temperature control device is similar to that of the first temperature control device. However, since the semen collection device lacks a housing, an inner shell can be provided within the second temperature control device. This inner shell is used to wrap a heating resistor to prevent direct heating of the semen collection cup 3 and semen collection tube 4, which could cause thermal damage. By configuring the first and second temperature control devices, the artificial vagina 2 and semen collection device are kept within a reasonable temperature range, reducing the risk of external influences on semen and ensuring semen quality and motility.

[0065] The artificial alpaca body 1 and artificial vagina 2 of the present invention are based on the traditional artificial vagina method for semen collection of livestock, combined with the reproductive physiological characteristics of alpacas, to construct the lying posture of the alpaca during real mating, to construct a continuous constant temperature environment in the artificial vagina 2, and to construct an ejaculation environment in the alpaca artificial vagina 2, which can truly simulate the natural mating environment of alpacas to collect high-quality alpaca semen.

[0066] In one embodiment, the outer tube 211 (e.g., an aluminum tube) of the prosthetic vagina body 21 has a circular hole 5 cm from the edge, and a water injection and pressure valve is installed using a gasket. Inside the tube 211, an inner tube 212 is installed. The inner tube 212 is made of natural latex, which is non-toxic to semen. A thermocouple is placed around the tube 211. The heating resistor wire is 220V, 50W, and the thermocouple is CU50. The thermocouple and the heating resistor wire are connected via wires to a digital temperature controller (XH-W3002 model), with a temperature measurement range of -50°C to 110°C and a control range of -50°C to 110°C, with a control accuracy of 0.1°C. The digital temperature controller is set to a temperature and powered on. When the temperature of the inner tube 212 is below the set temperature, a circuit is established, and the heating resistor wire operates. When the temperature of the inner tube 212 is above the set temperature, a circuit is established, and the heating resistor wire does not operate. This ensures that the temperature of the inner tube 212 of the artificial vagina 2 remains constant for extended periods. The body 211 of the artificial vagina 2 is 28 cm long and 6.5 cm in diameter. It is wrapped in aluminum foil for insulation. The inner tube 212 is 41 cm long, 5 cm in inner diameter, and 0.1 cm thick. 550 ml of warm water can be filled through a water injection valve and stored in the space between the inner tube 212 and the body 211. A first temperature control device maintains the temperature at 39°C ± 1°C. The rear section of the artificial vagina 2 is detachably connected to the semen collection cup 3 and the semen collection tube 4. The semen collection cup 3 is 15 cm long, with a front diameter of 6.5 cm and a rear diameter of 1 cm. The semen collection tube 4 is a 5 ml test tube with a 1 cm diameter. Semen collection cup 3 and semen collection tube 4 are equipped with independent heating and insulation sleeves as a second temperature control device. This sleeve is an aluminum tube with an inner tube 212 installed inside. A 220V, 50W heating resistor wire and a CU50 thermocouple are placed around the outside of the aluminum tube. The thermocouple and heating resistor wire are connected via wires to a digital temperature controller (XH-W3002 model). The temperature range is -50°C to 110°C, and the control range is -50°C to 110°C with a control accuracy of 0.1°C. The temperature is maintained at 36°C ± 1°C. This sleeve encloses semen collection cup 3 and semen collection tube 4, ensuring that semen is always at the appropriate temperature for collection and storage.

[0067] The installation and debugging process of the artificial vagina 2 of the present invention is as follows:

[0068] Clean the body 211 and inner tube 212 of the prosthetic vagina main body 21 with disinfectant. Autoclave the sperm collection tube 4 and set aside. Connect the sperm collection tube 4 to the inner tube 212 using the sperm collection cup 3. Place the inner tube 212 of the prosthetic vagina main body 21 into the body 211 of the prosthetic vagina 2, turning both ends outward onto the body 211 and securing them with rubber rings. Inject 550ml of water through the water injection and pressure valve until the inner tube 212 collapses into a "Y" shape. Connect the thermocouple and heating resistor to the digital temperature controller and set the temperature. Turn on the power and, after several minutes, check that the temperature and pressure of the inner tube 212 of the prosthetic vagina main body 21 are appropriate. At this point, assembly and commissioning of the prosthetic vagina main body 21 are complete. After wrapping the outer shell 22 around the prosthetic vagina main body 21, the prosthetic vagina 2 is assembled and secured to the first placement slot 11 of the prosthetic vagina main body 1.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
