[0002] The body size parameters of giant pandas refer to the body length, height, hip height and other related parameters of giant pandas. The measurement of giant panda body size plays an important role in the healthy breeding of giant pandas. It not only reflects their growth and development, but is also closely related to their physical condition assessment. It also provides a reference for animal husbandry experts in physical condition assessment, environmental enrichment, breeding pairing, etc. Therefore, during the breeding process of giant pandas, it is necessary to regularly measure the body size parameters of giant pandas.

[0003] At present, the commonly used method for measuring the body size of giant pandas is the traditional contact measurement method, which uses tools such as measuring sticks, tape measures and tape measures to manually measure the body size of giant pandas. Because giant pandas are aggressive and easily stressful to people, manual measurement generally requires anesthesia for adult giant pandas. This method is difficult to measure, inefficient, and the measurement results are easily affected by human subjective factors.

[0004] Therefore, there is an urgent need to develop a simple and efficient method for measuring the body size of giant pandas that is harmless to the giant pandas. Summary of the invention

[0026] The present invention provides a non-contact method for measuring the body size of giant pandas. The body size data of giant pandas can be measured by measuring other points and calculating. This method has a revolutionary effect on the measurement of the body size of adult giant pandas. It can not only reduce anesthesia and ensure safe breeding, but also reduce labor, and the measurement method is simpler and more efficient.

[0027] The present invention mainly adopts a laser measuring instrument for rapid measurement, and any brand of laser measuring instrument can be selected. In particular, the present invention determines for the first time the measurement points of various body size-related indicators when the giant panda's body size is measured by a laser measuring instrument, namely: the key points corresponding to the trunk length are the parietal bone and the coccygeal vertebrae, the corresponding position of the coccygeal vertebrae is at the end of the giant panda, the middle position of the tail root, and the distance between the two points is the trunk length. The key points corresponding to the head length are the incisor and the parietal bone, the corresponding position of the incisor is the front end of the giant panda, the corresponding position of the parietal bone is the middle position between the two ears, and the distance between the two points is the head length. The body length is the distance from the head to the tail of the giant panda, that is, the sum of the head length and the trunk length. The key points corresponding to the body height are the scapula and the carpal bones, the corresponding position of the scapula is the highest point of the body, and the corresponding position of the carpal bones is the ground corresponding to the carpal bones in actual measurement, and the distance between the two points is the body height. The key points corresponding to hip height are the coccyx and tarsus. The position of the coccyx is at the very end of the giant panda, in the middle of the base of the tail. The position of the tarsus is the ground corresponding to the tarsus in actual measurement. The distance between the two points is the hip height.

[0028] The screening of the above-mentioned points in the present invention is also carried out through repeated deductions, and the measurement points are finally confirmed. The data of these points are used for measurement, which is most consistent with the data measured directly after anesthesia and has the highest accuracy.

[0029] The specific implementation modes of the present invention will be further explained below in conjunction with examples, but it does not mean that the protection scope of the present invention is limited to the scope described in the examples.

[0030] Example: Using the method of the present invention to measure the body size of adult giant pandas

[0031] The experiment was conducted at the China Conservation and Research Center for the Giant Panda. Three adult giant pandas were selected and their body sizes were measured using the method of the present invention and the existing method, respectively.

[0032] The steps of body measurement of the method of the present invention are shown in Figure 1 .

[0033] Take the giant panda to a standing position, choose a safe and measurable distance position, fix the laser measuring instrument in a horizontal position, measure the distance from the measuring instrument to the parietal bone, which is the middle part between the two ears, and record the distance between the two points as a1; measure the distance from the measuring instrument to the coccyx, the corresponding position of the coccyx is at the very end of the giant panda, which is the middle part of the base of the tail, and record the distance between the two points as b1; use a goniometer to measure the angle C1 between a1 and b1; record the relevant values. According to the cosine theorem, the third side can be calculated when the two sides and the angle of a triangle are known. Define the trunk length of the panda as L1, then like Figure 2 shown.

[0034] The position from the measuring instrument to the incisor, that is, the front end of the giant panda, is measured as a2; the position from the measuring instrument to the parietal bone, that is, the middle part between the two ears, is measured as b2; the angle C2 between a2 and b2 is measured with a goniometer, and the relevant values ​​are recorded. Define the length of the panda's head as L2, then like Figure 3 shown.

[0035] The body length of the giant panda is the length from the front to the end of the body. Due to its special body characteristics, its body length cannot be directly measured without anesthesia. In non-contact measurement, its body length is equal to the sum of the head length and the trunk length. The body length of the giant panda is defined as L, then L = L1 + L2, such as Figure 4 shown.

[0036] Measure the position of the measuring instrument to the shoulder blade, which is the highest point of the giant panda's body, and record the distance between the two points as a3; measure the position of the measuring instrument to the wrist bone, which is usually the ground, and record the distance between the two points as b3; use the goniometer to measure the angle C3 between a3 and b3, and record the relevant values. Define the height of the panda as H1, then like Figure 5 shown.

[0037] The distance from the measuring instrument to the coccyx is measured as a4, the distance from the measuring instrument to the tarsus is measured as b4, the angle between a4 and b4 measured by the goniometer is C4, and the hip height of the panda is defined as H2. like Figure 6 shown.

[0038] The existing determination method operates as follows:

[0039] The anesthetized giant pandas were weighed in advance and fasted for 12 hours. The required anesthetic drugs were sucked into a metal syringe for use. When the giant pandas were lured to the iron railings with food, the drugs were quickly injected into the muscles in front of the animal's shoulders or arms. The body size of the giant pandas was measured under anesthesia. A soft tape measure was used for contact measurement. The two points corresponding to the trunk length were the parietal bone and the coccygeal vertebrae; the two points corresponding to the head length were the incisor and the parietal bone; the body length was the distance from the head to the tail of the giant panda, that is, the sum of the head length and the trunk length; the two points corresponding to the body height were the scapula and the carpal bones; the two points corresponding to the hip height were the coccygeal vertebrae and the tarsal bones.

[0040] The body size data of the three giant pandas are shown in Table 1 below.

[0042]

[0043] It can be seen that the method of the present invention can more simply and efficiently measure the body size data of giant pandas, the measurement results are slightly different from those of existing measurement methods, the measurement results are accurate and reliable, and have important significance.
