[0002] Multiple vertebrae traits are important economic traits of livestock, and as the number of vertebrae increases, the body length of livestock will naturally increase, which is beneficial to improve meat yield and wool yield. This phenomenon is particularly evident in pig breeding. The long white, big white and duroc pig breeds introduced by China all have larger body size due to multiple vertebrae, resulting in more excellent body type. Research data on Sichuan yaks show that for each additional vertebra, the body length of a yak increases by 7.6 cm, and the body weight increases by nearly 17 kg. Therefore, it is very meaningful to study the multiple vertebrae traits of yaks and use them as key characteristics for breeding.

[0003] The survey results of the multiple vertebrae traits of 2553 yaks from 6 yak breeds in the Qinghai-Tibet Plateau pastoral area show that the yak population generally has multiple thoracic and lumbar vertebrae variations that can increase body length and weight, with a proportion of 21.66%. This has the potential to select and breed new high-yield yak breeds with multiple thoracic and lumbar vertebrae, and is an extremely valuable breeding resource. Existing molecular screening technology can detect large groups of living organisms and can increase the proportion of multiple vertebrae in yak populations by 3 times. However, molecular screening technology can only be used for preliminary screening of multiple vertebrae breeding populations, and cannot guarantee that each individual in the basic population selected is a multiple vertebrae yak. The accuracy of molecular screening technology cannot reach 100%, which can seriously affect the breeding process. Molecular screening technology also has the problems of high cost and time consumption.

Therefore, how to detect the number of vertebrae in living yaks has become a technical obstacle to breeding multiple vertebrae yaks. Therefore, there is an urgent need in the art to develop a living detection technology that can ensure a 100% multiple vertebrae rate in the premise of molecular screening technology for large groups of yaks with multiple vertebrae traits.

[0034] In order to make the skilled in the art better understand the technical scheme in the utility model, the following will be further explained by several specific embodiments to realize the technical scheme of the utility model, and it is to be explained that the technical scheme of the utility model that the utility model claims includes but is not limited to the following embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the skilled in the art without making creative labor should belong to the scope of protection of the utility model.

[0035] Embodiment 1

[0036] DR (Digital Radiography, direct digital flat X-ray imaging system) refers to the technology of directly carrying out digital X-ray photography under the control of a computer, adopting an amorphous silicon flat panel detector to convert X-ray information penetrating a biological body into a digital signal, and reconstructing an image by a computer and carrying out a series of image processing. The DR system mainly comprises an X-ray generator, a direct conversion flat panel detector, a system controller, an impact monitor, an image processing workstation and the like, and the current DR is widely applied in hospitals and pet hospitals.

[0037] At present, the existing animal thoracic and lumbar spine number detection device generally uses a frame structure as the main structure of the restraint device, and then installs a rail or a crossbar around the frame to realize the restraint of the animal. Generally, such a structure can be reliably restrained for animals such as sheep and horses with gentle character, but for yaks which are smart and fierce, the restraint structure of the frame matched with the crossbar cannot realize reliable restraint. If the gap between the crossbars is too large when the yak enters the restraint frame body, the head horn and the lower hoof of the yak are likely to rush out of the gap between the crossbars, thereby causing a safety accident of bumping or kicking a staff on one side, resulting in injury of the staff, and the safety of the device is low. If the crossbar is encrypted to reduce the gap, the metal crossbar will affect the imaging effect of the DR equipment, and then affect the detection result of the number of thoracic and lumbar vertebrae of the yak.

[0038] Based on this, the embodiment discloses a yak thoracic and lumbar spine number detection device based on DR, which can not only improve the restraint reliability of the device for yaks, but also will not affect the imaging effect of the DR equipment. Referring to the structural diagram of the detection device shown in the specification Figures 1-3 The device is composed of a shed 1, a lane 2 and a restraint frame body 3 connected in sequence, the entrance and the exit of the lane 2 are connected with the exit of the shed 1 and the entrance of the restraint frame body 3 respectively; the restraint frame body 3 is a frame structure with open front and back sides, the open back side is the exit of the restraint frame body 3, and the open front side is the corresponding entrance, and the internal space of the frame from the entrance to the exit is a detection area, the yak to be detected is restrained in the detection area and completes the photographing of the DR equipment, so the structure of the restraint frame body 3 is crucial to realize the safe and reliable restraint effect of the yak. In the embodiment, referring to the structural diagram of the detection device shown in the specification Figure 4 and Figure 5The fixing frame body 3 is composed of a bottom plate 31 and stand columns 32 arranged at four corners of the bottom plate 31, adjacent stand columns 32 are connected through upper tie rods 4 arranged at the top of the stand columns 32, the main body frame is fixed and tied to form a whole; further, two stand columns 32 on the left and right sides of the fixing frame body 3 are respectively provided with a lower cross bar 5, at least two upper baffles 6 are arranged between the lower cross bar 5 and the upper tie rod 4, and at least one upper baffle 6 is arranged close to the exit of the fixing frame body 3 and used for shielding the head of the yak in the detection area; the upper and lower ends of the upper baffle 6 are provided with hooks 7, and the hooks 7 at the two ends are respectively hung on the upper tie rod 4 and the lower cross bar 5; further, the lower cross bar 5 is fully paved with a lower baffle 8 which is fixedly connected with the stand columns 32 on the two sides; the outer sides of the left and right sides of the fixing frame body 3 are respectively provided with a transmitter 9 and a receiver 10, and the transmitter 9 and the receiver 10 are respectively connected with a controller of a DR system; a horizontal guide rod 11 for driving the yak to the side close to the receiver 10 is arranged in the detection area of the fixing frame body 3.

[0039] In the embodiment depicted in the utility model, the shed 1 and the lane 2 are composed of commonly used guardrails, and the utility model does not specially limit the structure of the shed 1 and the lane 2. In addition to arranging the lane 2 at the entrance, the lane 2 structure can also be correspondingly arranged at the exit of the fixing frame body 3, and the yak is discharged through the lane 2 after detection.

[0040] In the embodiment depicted in the utility model, it can be understood that the lower cross bar 5, the stand column 32 and the upper tie rod 4 arranged on the left and right sides of the main body frame of the fixing frame body 3 form an upper baffle frame on the left and right sides of the frame body, the upper baffle 6 is installed in the upper baffle frame, and in order to ensure safety, the gap between adjacent upper baffles 6 in the upper baffle frame and the gap between the upper baffle 6 at the edge and the stand column 32 are very small, so as to avoid the horn of the yak from passing through the gap and injuring the staff on one side.

[0041] In addition, the upper and lower ends of the upper baffle 6 are provided with hooks 7, the upper end hook 7 is hung on the upper tie rod 4, and the lower end hook 7 is hung on the lower cross bar 5, so that the lower end of the upper baffle 6 is also fixed, and the non-moving end can avoid the upper baffle 6 from being kicked over by the yak from the lower part.

[0042] Similarly, for the lower horizontal bars 5 and the columns 32 on the left and right sides, they can also be combined with the bottom plate 31 to form a lower baffle frame on the corresponding side, and the lower baffle 8 is installed in the lower baffle frame. And because when detecting the yak thoracic and lumbar spine, it is usually to shoot the image of the position from the abdomen to the back of the yak, there is no requirement for the photographing of the lower part of the cow foot, so the lower baffle 8 can be fully paved in the lower baffle frame to prevent the cow foot from sticking to the staff from the gap, but there can also be a gap, and similarly if there is a gap, the gap needs to be very small to avoid the cow foot from passing through the gap and injuring the staff on one side.

[0043] It should be emphasized that only one yak (i.e. only one yak is allowed in the detection area) is allowed in the holding frame 3 during detection, and the rest of the yaks are waiting in the shed 1 or the waiting area.

[0044] In the embodiment depicted in the utility model, the yak to be detected is driven from the shed 1 into the lane 2, and then from the lane 2 into the detection area of the holding frame 3. After entering the holding frame 3, the yak is closer to the receiver 10 and farther away from the transmitter 9 under the action of the lateral guide rod 11 on one side. Then the yak horn is tied to the column 32 with a rope, and the yak is fixed in the holding frame 3. The transmitter 9 and the receiver 10 are operated to take a photo of the area from the abdomen to the back of the yak, and then the photo is sent to the back-end processing device such as a computer, and finally the number of thoracic and lumbar spines of the yak is obtained.

[0045] It can be understood that the two ends of the horizontal lateral guide rod 11 are fixedly connected with the two columns 32 on the side where the transmitter 9 is located, and are arranged in the extension direction from the entrance to the exit of the holding frame 3. The lateral guide rod 11 increases the distance between the yak and the transmitter 9, so that after the yak enters the holding frame 3, it is driven to the side close to the receiver 10 under the action of the lateral guide rod 11.

[0046] It should be noted that when taking a photo, the upper baffles 6 on both sides of the position of the yak tail can be removed, and then the photo can be taken, and then the upper baffles 6 at the middle position can be moved to the tail along the upper draw-in rod 4 and the lower horizontal bar 5 (the upper draw-in rod 4 and the lower horizontal bar 5 serve as the track of the upper baffles 6 during movement), and then the transmitter 9 and the receiver 10 are moved to continue taking photos, and finally the whole image acquisition work is completed. It should be noted that only the upper baffles 6 at the middle and tail positions are removed during photography, and the upper baffles 6 at the position of the yak's head and neck cannot be removed to avoid safety accidents caused by the yak's horn attacking the on-site operator.

[0047] Embodiment 2

[0048] The embodiment discloses a yak thoracic and lumbar spine number detection device based on DR, and the specific description is as follows Figure 2 andFigure 3 As shown, based on Embodiment 1, slide rails are respectively provided on the outer sides of the left and right sides of the Baoding frame 3, and the transmitter 9 and receiver 10 are slidably mounted on the corresponding slide rails by sliders.

[0049] In the embodiment described in this utility model, the transmitter 9 and the receiver 10 are slidably mounted on a slide rail. When taking pictures of yaks, by continuously moving the positions of the transmitter 9 and the receiver 10, a complete image of the yak from neck to tail can be captured, which is used to identify the number of thoracic and lumbar vertebrae in the yak.

[0050] Preferably, the exit of the Baoding frame 3 is provided with an exit door 12, the exit door 12 includes a door frame, the door frame is connected to the column 32 at the exit; a central crossbar is provided in the middle of the door frame, several railings are provided above the central crossbar, and a door panel is provided below the central crossbar.

[0051] In the embodiment described in this utility model, the structure of the exit gate 12 is divided into upper and lower parts by a horizontal bar in the middle. The area above the horizontal bar is provided with multiple railings from top to bottom. The railings can be used to tie the yak's horns and fix the yak in the yak frame 3. Then, the blank area from the middle horizontal bar to the bottom plate 31 is fully covered with door panels. The door panels are used to block the yak's feet and prevent it from kicking and injuring the staff.

[0052] Preferably, a waiting area is provided between the alleyway 2 and the enclosure 1, and an isolation door is provided between the waiting area and the alleyway 2.

[0053] In the embodiment described in this utility model, a waiting area is added between the alleyway 2 and the pen 1. In actual operation, a yak can be driven into the waiting area in advance to wait. After the previous yak has been inspected, the yak in the waiting area can be quickly driven into the saddle frame 3 for inspection, which significantly improves the inspection efficiency of the device.

[0054] It is understood that the waiting area can also be a tunnel structure.

[0055] Preferably, in order to avoid affecting the DR equipment's photography, the upper baffle 6 is made of wood, and in order to ensure the safety of the device, a high-strength board such as hard fiberboard is used to prevent the yak from breaking or cracking the board.

[0056] Preferably, to further improve the strength of the wooden board, a reinforcing frame is provided around the upper baffle 6, which can be made of metal. Since metal materials can affect the DR equipment's imaging, during photography, one section of the upper baffle at the yak's tail can be removed, and then the middle upper baffle can be moved so that the metal structure of the upper baffle does not obstruct the transmitter and receiver, ensuring image quality. However, it is important to emphasize that the upper baffle 6, typically located at the end of the frame and used to shield the yak's head, cannot be disassembled or moved to prevent the yak from realizing it has a chance to escape and charging at the device, causing unnecessary safety accidents.

[0057] Preferably, the base plate 31 of the Baoding frame 3 is equipped with a detection platform for supporting yaks, and lifting mechanisms are provided at the four corners of the detection platform, making the height of the detection platform adjustable. During detection, the yak stands on the detection platform, and the entire detection platform can be moved up and down by operating the lifting mechanisms. Therefore, it is possible to increase the height of yaks with shorter body sizes, ensuring that yaks of all sizes can achieve good photographic results.

[0058] It is understood that the lifting mechanism can typically be a hydraulic cylinder, which is fixed on the base plate 31 and its movable end is connected to the testing platform to drive the testing platform to rise and fall.

[0059] As another implementation method, pads or blocks can be set on the base plate 31 of the Baoding frame 3 to increase the height of yaks with shorter body size, thereby ensuring that photos of the yak's abdomen and back can be taken.

[0060] Example 3

[0061] This embodiment discloses a diaphragm-based device for detecting the number of thoracic and lumbar vertebrae in yaks. The usage and working principle of the device are as follows:

[0062] The first step is to drive all the yaks that need to be tested into pen 1.

[0063] The second step involves moving the yak to be tested from pen 1 into the waiting area. Once the previous yak has been tested, the isolation door of the waiting area is opened, and the yak to be tested is moved into passageway 2, and then from passageway 2 into the testing area of ​​the yak enclosure 3. After the yak enters the testing area, its horns are tied to the railing of the exit gate 12, thus securing the yak inside the yak enclosure 3.

[0064] The third step is to visually observe the size of the yak to be tested, and then adjust the parameters of the DR machine, including voltage and current, and adjust the height of the restraint frame 3 according to the height of the yak so that the upper part of the transmitter 9 is basically level with the back of the yak.

[0065] Fourthly, clamp the clamps on the back of the yak. Specifically, touch the junction of the neck and back of the yak with the hand, and find a round protrusion as the starting point. From the protrusion, clamp the clamps at an interval of one palm. Clamping is continued until the tail vertebrae of the yak is reached.

[0066] When clamping the clamps, attention should be paid to clamping to the deep part of the hair and as close to the root as possible. If the clamps are clamped at the end of the hair, the clamps will be displaced relative to the body when the yak shakes, thereby affecting the positioning effect of the vertebrae by means of the clamps.

[0067] Fifthly, move the transmitter 9 and the receiver 10 to take pictures of the yak. Generally, 6 pictures are taken for small calves, and 10 pictures are taken for large calves. After the shooting is completed, the clamps are recovered and removed.

[0068] It should be noted that when taking pictures, the upper baffle 6 on the left and right sides of the fixing frame 3 is generally made of wood, which does not generally affect the shooting of the DR device. However, if a reinforcing frame made of metal material is installed around the upper baffle 6, the upper baffle 6 at the corresponding position can be removed before shooting. It should be noted that the upper baffle 6 at the position of the head and neck of the yak cannot be removed, so as to avoid safety accidents caused by the yak horn colliding with the on-site operator.

[0069] Sixthly, after the shooting is completed, the images are uploaded to the computer, and then the number of thoracic and lumbar vertebrae of the yak is directly obtained by counting the pictures.

[0070] Based on the images, the process of identifying the number of thoracic and lumbar vertebrae of the yak is as follows:

[0071] Firstly, the position of the first thoracic vertebra is found. The thoracic vertebra is very long, and the cervical vertebra is very short. The difference between the two is very obvious. Then count to the junction of the thoracic and lumbar vertebrae to determine the number of thoracic vertebrae. The difference between the thoracic vertebra and the lumbar vertebra is that there are long ribs on the thoracic vertebra, while there are no ribs on the lumbar vertebra. Count from the lumbar vertebra to the tail vertebra to determine the number of lumbar vertebrae.

[0072] The difference between the lumbar vertebra and the tail vertebra is that: (1) the first tail vertebra is basically triangular, with a narrow left side and a wide right side; (2) there is a spinous process on the lumbar vertebra, and there is no spinous process on the tail vertebra.

[0073] Only a few vertebrae can be seen in each image, so it is necessary to look at the images one by one, and the positioning of the vertebrae between the front and back images is realized by means of the clamps simultaneously imaged on the images, so as to avoid counting errors and improve the speed.

[0074] In the description of the utility model, need understanding is, the orientation or position relation that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate is based on the orientation or position relation shown in the drawing, just is for the convenience of describing the utility model and simplifying the description, and is not indicate or imply that the device or element referred to must have a particular orientation, is constructed and operated in a particular orientation, therefore can not be understood as the restriction to the protection scope of the utility model.

[0075] In the description of the utility model, need to explain further is, unless another explicit provision and limitation, the terms "arrangement", "installation", "connection" should be broad understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through the intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0076] The above, only is the preferred embodiment of the utility model, and does not limit the utility model in any form, and any simple modification, equivalent change of the above embodiment according to the technical essence of the utility model, all fall within the protection scope of the utility model.
