At present, the weight of the dairy cows is indirectly estimated by means of body size measurement, and the body condition of the dairy cows is evaluated in the form of body condition score, which has a certain rationality, but since it is not directly measured, there is a certain error compared with the real weight, and it is difficult to accurately reflect the physical condition of the dairy cows.

[0003] According to the search, the disclosure (announcement) No. CN217716604U discloses a dynamic weighing device based on a pasture, which comprises a base and a platform scale body fixedly arranged on the base. The utility model discloses a height-adjustable universal wheel, which can be extended out of the support leg for movement, and can be retracted into the support leg for stable support of the equipment during weighing, thereby ensuring the stability during measurement. The cooperation of the movable plate, the electric push rod, the adjusting plate, the bottom plate, the screw hole and the fixed screw rod can form a slope, which is convenient for driving the dairy cow to stand on the platform scale for weighing. However, the application lacks a limiting mechanism for the cow, so that the cow will move during weighing, thereby affecting the weighing data.
