Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of livestock appliances, and specifically to a rapid pig hip circumference measuring device. BACKGROUND

[0002] "Pig food makes the world, and good breeds lay the foundation stone". The pig industry is the pillar industry of China's animal husbandry and even agriculture and rural areas. Since the reform and opening up, China's pig industry has developed steadily and has become a truly world's first pig-raising country, but the overall production efficiency of pigs is still low. Specifically, taking 2023 as an example, in 2023, China's year-end inventory accounted for 58.16% of the world's pig inventory, contributing 54.89% of the world's pig inventory, but the pork production accounted for only 48.92%, the overall production efficiency was only 84.11% of the world's average level, 78.03% of Europe and the United States, and only 75.43% of the United States. The overall production efficiency needs to be improved. Meat production trait improvement is an important direction of China's pig breeding, and meat production capacity is an important indicator to evaluate the value of pigs.

[0003] The current direct evaluation indicators of pig meat production capacity mainly include carcass weight, dressing percentage, and lean meat percentage, etc. In breeding work, it is required to reflect the live measurement indicators for breeding, and hip circumference reflects the development of pig hip muscles, which is an important indicator to evaluate the meat production capacity of pigs. However, there is currently a lack of professional measuring tools, and soft rulers are mainly used for measurement. When measuring, the measuring personnel need to hold the soft ruler from the front edge of the left knee joint of the pig to the front edge of the right knee joint through the anus, and in most cases, the measuring personnel need to embrace the pig's hip to complete the measurement. First, the measurement accuracy is poor due to limited field of view, and second, the measuring personnel embracing the pig's hip and facing the pig's anus are extremely unfriendly to the measuring personnel. Therefore, a simple and rapid hip circumference measuring device is needed in the process of measuring the performance of breeding pigs. At the same time, high temperature, ultraviolet rays, formaldehyde fumigation and other means are widely used in current breeding production lines to disinfect instruments, and production line tools are required to have the characteristics of high temperature resistance, corrosion resistance, simple structure and not easy to be damaged.
