Description

Technical Field

[0001] The present invention relates to the field of animal husbandry technology, and in particular to a device and method for analyzing genetic data of mutton sheep and selecting improved varieties based on machine learning. Background Art

[0002] In the animal husbandry industry, the physiological functions of domesticated animals such as livestock and poultry, or wild animals such as sheep, deer, musk deer, foxes, minks, otters, and quails are utilized to artificially feed and reproduce them, so that they can convert plant energy such as pasture and feed into animal energy to obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk, and medicinal herbs. Different from self-sufficient livestock breeding, the main characteristics of animal husbandry are centralization, scale, and profit-making as the production purpose. In the process of selecting and breeding meat sheep, the weight and body size of the meat sheep need to be measured.

[0003] Existing examples include an automatic weight and size measurement device for selecting and breeding new breeds of mutton sheep, for example, with Chinese Publication No. CN115014485A. Its description states, "The present invention discloses an automatic weight and size measurement device for selecting and breeding new breeds of mutton sheep, belonging to the technical field of animal husbandry equipment. The device comprises a guided weight measurement mechanism, comprising a rectangular base and a main body block. The main body block is located on one side of the upper surface of the rectangular base. Frames are provided at the upper edges of both sides of the outer wall of the main body block, and the two frames are at the same horizontal height. A plurality of side frames are linearly arranged at equal intervals on the lower side of each frame, and the lower end of each side frame is interconnected with the upper surface of the rectangular base. A multi-point photography and size measurement mechanism is provided within the inner cavity of the main body block."

[0004] The existing device can guide the sheep's line of sight, divert their attention, reduce the sheep's movement during measurement, and reduce the difficulty of measurement. At the same time, the camera can move around the sheep to take pictures and measurements from multiple angles and directions, greatly improving the accuracy of the pictures. However, there are the following shortcomings:

[0018] A method for using a device for analyzing genetic data of mutton sheep and selecting improved varieties based on machine learning, comprising the following methods:

[0019] Step 1: During the sheep introduction phase, the intelligent linkage access control mechanism is activated, the dual-axis motor runs, and the bevel gear transmission drives the rotating rod to rotate, so that the movable door is opened. At the same time, the connecting frame drives the step plate to be lowered, guiding the sheep to pass through the step plate and enter the fence mechanism. After the sheep enter, the dual-axis motor runs in the reverse direction to close the movable door and lift the step plate;

[0020] Step 2: During the weight and size measurement phase, after the sheep enter the pen, they will be attracted by the food in the food box and naturally walk to the scale. The scale automatically measures and records the sheep's weight data. According to the sheep's body shape, the electrical control cabinet controls the extension and retraction of the multi-stage electric push rod of the body size measurement height adjustment mechanism, adjusting the multi-point shooting body size measurement mechanism to the appropriate height. Then, the multi-point shooting body size measurement mechanism shoots the sheep from multiple angles, obtains body size data, and transmits it to the body size and weight measuring instrument for analysis and processing;

[0021] Step 3: During the sheep head posture adjustment and genetic sample collection stage, after the weight and body size measurements are completed, the second servo motor is used to control the winding roller to rotate, so that the tether moves downward and is suitable for the height of the mutton sheep. The collar is then placed on the lower jaw of the mutton sheep. Subsequently, the second servo motor is used to control the winding roller to rotate in the opposite direction, so that the collar slowly moves upward to lift the head. At the same time, the electric slide rail drives the electric slider to move, thereby driving the collar to move, so that the sheep's neck is tilted to one side for easy sampling. Then, the audio player is turned on to play specific sounds to soothe the mutton sheep's emotions and reduce the mutton sheep's stress response. The retractable robotic arm is operated to drive the sampling needle to the sampling position, and the sampling pump is started to collect genetic samples from the mutton sheep. The collected samples are transported to the mixing cylinder through the telescopic hose and the sampling pump;

[0022] Step 4: Gene sample processing and analysis stage, by starting the first servo motor, the sample is stirred evenly by the stirring shaft and the stirring rod, the metering pump is started to open the solenoid valve on the extraction tube, and the metering pump extracts a certain amount of sample and the corresponding proportion of diluent into the dilution cylinder. The rotating stirring rod will stir and mix the sample and the diluent to reach the predetermined dilution concentration, and the solenoid valve on the delivery tube is opened to allow the diluted sample to be transported to the reaction cylinder again, and the corresponding extraction pump is started and the solenoid valve on the corresponding extraction tube is opened. The specific binding buffer is extracted from the corresponding reaction liquid storage cylinder and added to the reaction cylinder, so that the magnetic beads can specifically bind to the target nucleic acid molecules in the gene sample. At the same time, the rotating stirring rod makes the magnetic beads fully contact with the sample during the rotation process, and the target nucleic acid molecules are combined with the magnetic beads. Subsequently, the electromagnetic coil is energized to generate a high-intensity magnetic field, which binds the target nucleic acid molecules to the magnetic beads. The magnetic beads of acid molecules are adsorbed on the inner wall of the reaction cylinder, while the impurities in the sample remain in the solution. The solution containing impurities is discharged by opening the solenoid valve on the drain pipe. Then, the corresponding extraction pump is started and the solenoid valve on the corresponding extraction pipe is opened. The washing buffer in the reaction liquid storage cylinder is added to the reaction cylinder. The magnetic beads are washed multiple times to remove residual impurities. Finally, the corresponding extraction pump is started and the solenoid valve on the corresponding extraction pipe is opened. The elution buffer in the reaction liquid storage cylinder is added to the reaction cylinder to separate the target nucleic acid molecules from the magnetic beads to obtain a purified gene sample. The solenoid valve on the discharge pipe is then opened to allow the processed sample to flow into the analysis tube through the discharge pipe and the mounting seat. The staff can rotate the analysis tube to remove it so that the analysis tube is located in the insertion slot of the analysis disk on the genetic data analyzer. The genetic data analyzer then performs genetic data analysis in combination with a machine learning algorithm.

[0023] Step 5: During the data integration and breeding stage, the genetic data analyzer transmits the analyzed genetic data together with the weight and body size data obtained by the weighing device and the multi-point body measurement mechanism to the electrical control cabinet. The machine learning algorithm is used to integrate and analyze multi-source data, build a comprehensive evaluation model, screen out individual mutton sheep with excellent genes and traits, and generate breeding recommendations. The operator then conducts subsequent mutton sheep breeding work based on the recommendations.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention uses a retractable mechanical arm in the collection and analysis mechanism to drive a sampling needle to collect genetic samples from mutton sheep. The sampling pump transports the sample to a mixing cylinder, and cooperates with a metering pump and a diluent storage cylinder to dilute the sample. The diluted sample is then sent to a reaction cylinder through a delivery tube. The extraction pump transports reaction solutions such as specific binding buffer, washing buffer and elution buffer to the reaction cylinder. The electromagnetic coil outside the reaction cylinder cooperates with magnetic beads to process the sample. The first servo motor drives the stirring shaft and stirring rod to stir the sample. Finally, the genetic data analyzer performs genetic data analysis on the processed sample, thereby realizing the collection and analysis of mutton sheep genetic data. This solves the problem that existing devices are inconvenient to collect mutton sheep genetic samples, lack the function of collecting and analyzing mutton sheep genetic data, and are difficult to accurately screen out mutton sheep individuals with excellent genes, thereby reducing the efficiency and accuracy of mutton sheep breeding.

[0026] 2. After the dual-axis motor in the intelligent linkage access control mechanism of the present invention is started, its two output ends drive the two drive shafts to rotate. Since the four bevel gears are engaged with each other, the two rotating rods rotate synchronously. When the rotating rods rotate, the movable door fixed on its outer surface rotates accordingly, realizing automatic opening and closing of the movable door. At the same time, during the rotation of the two drive shafts, the connecting frame fixedly sleeved on its outer surface also rotates accordingly. The connecting frame moves through the fixed shell, and the step plate fixed on its top will automatically lower and lift as the connecting frame rotates. That is, when the movable door is opened, the step plate is lowered, and the mutton sheep can enter and exit the fence through the step plate; when the movable door is closed, the step plate is lifted to prevent the mutton sheep from entering and exiting at will, thereby ensuring the orderly management of the mutton sheep in the fence.

[0027] 3. The present invention adjusts the posture of the sheep's head by using the second servo motor in the collection mechanism to drive the winding roller to rotate. The sheep's head can be pulled up and down by driving the ring. At the same time, the electric slide rail drives the electric slider to move, and then drives the U-shaped frame and the winding roller to move, so that the sheep's neck can be tilted to one side, and the sheep can be fixed in a posture that is convenient for blood collection, which facilitates the collection and measurement of genetic samples from meat sheep and improves the convenience of operation.

The meshing transmission of bevel gears 306 ensures the synchronous rotation of the two rotating rods 302, allowing the two movable doors 303 to open or close simultaneously, improving the consistency and stability of the door opening and closing. The connection frame 307 and the step plate 308 are arranged to realize the automatic lowering and raising of the step plate 308. When the movable door 303 is opened, the step plate 308 is lowered to facilitate the entry and exit of the sheep; when the movable door 303 is closed, the step plate 308 is raised to prevent the sheep from entering and exiting at will. This linkage design makes the entry and exit process of the sheep smoother and more orderly. In conjunction with the guided weight measurement mechanism 5, the sheep are guided to naturally walk to the scale 501 for weight measurement, reducing the sheep's resistance and improving the accuracy and efficiency of the measurement data.

[0046] like Figure 1 、 Figure 2 and Figure 3As shown, the guiding weight measurement mechanism 5 includes a weighing device 501, which is installed on the top of the base 1. The top of the base 1 is fixedly connected to a food placement frame 502. The four support columns 201 are provided with a multi-point shooting body size measurement mechanism 6. The top of the support platform 4 is provided with a body size weight measuring instrument 11. The top of the frame 203 is provided with a body size measurement height adjustment mechanism 7. The body size measurement height adjustment mechanism 7 includes two multi-stage electric push rods 701. The two multi-stage electric push rods 701 are fixedly installed on the top of the frame 203. The telescopic ends of the two multi-stage electric push rods 701 are movable through the frame 203 and are fixedly connected to two connecting blocks 702. The two connecting blocks 702 are fixedly connected to the multi-point shooting body size measurement mechanism 6. A sheep head posture adjustment mechanism is provided on one side of the support platform 4. The weight collection mechanism 8 can automatically and accurately measure the weight of the mutton sheep through the weighing device 501. The food placement frame 502 uses the foraging habits of the mutton sheep to guide them to actively stand on the weighing device 501, thereby improving the convenience of weight measurement. The multi-point shooting body size measurement mechanism 6 cooperates with the body size measurement height adjustment mechanism 7. The shooting height is adjusted by the multi-stage electric push rod 701. The mutton sheep can be photographed from multiple angles and different heights to fully obtain the body size data of the mutton sheep. The body size and weight measuring instrument 11 quickly analyzes and processes the measurement data to improve measurement efficiency. The sheep head posture adjustment collection mechanism 8 cooperates with the weight and body size measurement mechanism. After the measurement is completed, the posture of the mutton sheep can be quickly adjusted to prepare for the collection of genetic samples, optimize the overall operation process, and improve the comprehensive work efficiency of the mutton sheep breeding device.

[0047] like Figure 7 As shown, the sheep head posture adjustment and collection mechanism 8 includes an electric slide rail 801, which is installed on one side of the support platform 4. An electric slider 802 is slidably connected to the electric slide rail 801, and one side of the electric slider 802 is fixedly connected to a U-shaped frame 803. The inner side of the U-shaped frame 803 is rotatably connected to a winding roller 804. The outer surface of the winding roller 804 is provided with a tether 805. The end of the tether 805 away from the winding roller 804 is fixedly connected to a ring 806. The combination of 02 enables the U-shaped frame 803 to move flexibly in the horizontal direction. The winding roller 804 cooperates with the tether rope 805 and the ring 806. The rotation of the winding roller 804 can realize the up and down movement of the ring 806, so that the sheep's head posture can be adjusted quickly and accurately according to the body shape of the meat sheep and actual sampling needs, and the sheep can be fixed in a posture convenient for blood collection, reducing the direct contact between the operator and the meat sheep, reducing the operation risk, and at the same time improving the efficiency and success rate of genetic sample collection, ensuring the quality of sample collection.

[0048] like Figure 1 、 Figure 2 and Figure 7As shown, a second servo motor 807 is fixedly connected to one side of the U-shaped frame 803, and the output end of the second servo motor 807 is movable through the U-shaped frame 803 and fixedly connected to the winding roller 804. An electrical control cabinet 10 is installed on one side of the multiple side frames 202, and the wiring terminal of the electrical control cabinet 10 is connected to the internal wiring port of the device. The second servo motor 807 provides stable and accurate power for the winding roller 804, and the rotation angle and speed of the winding roller 804 can be accurately controlled according to actual needs, thereby accurately adjusting the length of the tether 805 and achieving fine adjustment of the sheep's head posture. The electrical control cabinet 10 serves as the control core of the entire device. Through wiring connections with various internal components, it can uniformly control and coordinate the operation of various parts such as the intelligent linkage access control mechanism 3, the guided weight measurement mechanism 5, the body size measurement height adjustment mechanism 7, the sheep's head posture adjustment and collection mechanism 8, and the collection and analysis mechanism 9, thereby realizing automated and intelligent operation of the device, improving the stability of the device operation, and facilitating the centralized control and management of the entire mutton breeding process by the staff.

[0049] The usage and working principle of this device: During the preparation stage, the operator first checks whether the various components of the device are operating normally, ensures that the electrical control cabinet 10 is connected normally, that there is sufficient liquid in each storage cylinder (dilution liquid storage cylinder 909, reaction liquid storage cylinder 913) in the collection and analysis mechanism 9, and that the intelligent linkage access control mechanism 3, the guide weight measurement mechanism 5 and other equipment are in standby mode, and places food that attracts meat sheep in the food placement frame 502.

[0050] During the sheep introduction stage, the intelligent linkage access control mechanism 3 is started, the dual-axis motor 304 is in operation, and the rotating rod 302 is driven to rotate through the bevel gear 306, so that the movable door 303 is opened. At the same time, the connecting frame 307 drives the step plate 308 to be lowered, guiding the sheep to enter the fence mechanism 2 through the step plate 308. After the sheep enter, the dual-axis motor 304 runs in the reverse direction to close the movable door 303 and lift the step plate 308.

[0051] During the weight and size measurement stage, after the mutton enters the fence, it will be attracted by the food in the food placement box 502 and naturally walk onto the scale 501. The scale 501 automatically measures and records the mutton weight data. According to the body shape of the mutton, the multi-stage electric push rod 701 of the body size measurement height adjustment mechanism 7 is controlled by the electrical control cabinet 10 to extend and retract, and the multi-point shooting body size measurement mechanism 6 is adjusted to the appropriate height. Then, the multi-point shooting body size measurement mechanism 6 shoots the mutton from multiple angles, obtains body size data, and transmits it to the body size and weight measuring instrument 11 for analysis and processing.

[0052] During the sheep head posture adjustment and genetic sample collection stage, after the weight and body size measurements are completed, the second servo motor 807 controls the winding roller 804 to rotate according to the height of the mutton sheep, so that the tether 805 moves downward and is suitable for the height of the mutton sheep. The collar 806 is then put on the lower jaw of the mutton sheep. Subsequently, the second servo motor 807 controls the winding roller 804 to rotate in the opposite direction, so that the collar 806 slowly moves upward to pull up the head. At the same time, the electric slide rail 801 drives the electric slider 802 to move, thereby driving the collar 806 to move, so that the sheep's neck is tilted to one side for easy sampling. Then, the audio player 929 is turned on to play specific sounds to soothe the mutton sheep's emotions and reduce the mutton sheep's stress response. The retractable robotic arm 902 is operated to drive the sampling needle 904 to the sampling position, and the sampling pump 908 is started to collect genetic samples from the mutton sheep. The collected samples are transported to the mixing cylinder 905 through the retractable hose 928 and the sampling pump 908.

[0053] During the gene sample processing and analysis phase, in the mixing cylinder 905, the first servo motor 925 is activated, and the sample is stirred uniformly by the stirring shaft 923 and the stirring rod 924. Then, the metering pump 910 is activated to open the solenoid valve 920 on the liquid extraction tube 911. The metering pump 910 extracts a certain amount of sample and a diluent of a corresponding proportion into the dilution cylinder 906. The rotating stirring rod 924 stirs and mixes the sample and the diluent, so that the sample and the diluent are fully and uniformly mixed to reach a predetermined dilution concentration. After the sample concentration requirement of the gene data analysis instrument 926 is met, the solenoid valve 920 on the delivery tube 912 is opened to allow the sample to be diluted. The diluted sample is then transported to the reaction cylinder 907, and three reaction liquid storage cylinders 913 are used to store specific binding buffer, washing buffer and elution buffer respectively. The corresponding extraction pump 914 is started and the solenoid valve 920 on the corresponding extraction tube 915 is opened. The specific binding buffer is extracted from the corresponding reaction liquid storage cylinder 913 and added to the reaction cylinder 907. The surface of the magnetic beads 917 is specially modified and coated with a layer of polyethylene glycol, so that the magnetic beads 917 can specifically bind to the target nucleic acid molecules in the gene sample. At the same time, the rotating stirring rod 924 rotates during the rotation process, so that the magnetic beads 917 are fully in contact with the sample. The target nucleic acid molecules are combined with the magnetic beads 917. Subsequently, the electromagnetic coil 916 is energized to generate a high-intensity magnetic field, which adsorbs the magnetic beads 917 combined with the target nucleic acid molecules on the inner wall of the reaction cylinder 907, while the impurities in the sample remain in the solution. The solution containing impurities is discharged by opening the electromagnetic valve 920 on the drain pipe 918. Subsequently, the corresponding extraction pump 914 is started and the electromagnetic valve 920 on the corresponding extraction pipe 915 is opened to add the washing buffer in the reaction solution storage cylinder 913 into the reaction cylinder 907. The magnetic beads 917 are washed multiple times to remove the remaining impurities. Finally, the corresponding extraction pump 914 is started and the electromagnetic valve 920 on the corresponding extraction pipe 915 is opened to add the washing buffer in the reaction solution storage cylinder 913 into the reaction cylinder 907. Take the pump 914 and open the solenoid valve 920 on the corresponding extraction tube 915, add the elution buffer in the reaction liquid storage cylinder 913 into the reaction cylinder 907, so that the target nucleic acid molecules are separated from the magnetic beads 917 to obtain a purified genetic sample. Then, by opening the solenoid valve 920 on the discharge tube 919, the processed sample flows into the analysis tube 922 through the discharge tube 919 and the mounting seat 921. The staff can rotate the analysis tube 922 to remove it so that the analysis tube 922 is located in the insertion slot of the analysis disk on the genetic data analyzer 926, and then the genetic data analyzer 926 combines the machine learning algorithm to perform genetic data analysis.

[0054] During the data integration and breeding stage, the genetic data analyzer 926 transmits the analyzed genetic data together with the weight and body size data obtained by the weighing device 501 and the multi-point body size measurement mechanism 6 to the electrical control cabinet 10, and uses machine learning algorithms to integrate and analyze multi-source data, build a comprehensive evaluation model, screen out meat sheep with excellent genes and traits, and generate breeding recommendations. The operator then conducts subsequent meat sheep breeding work based on the recommendations.
