In recent years, China's livestock machinery has been widely developed, the status quo and development strategy of livestock machinery is particularly important.

1.1 grassland construction and herbage harvesting machinery

At present, the technical content of grassland construction machinery and herbage harvesting machinery in China is relatively low, and the equipment for grass seed processing is backward. Generally, it can only reach or approach the level 3 stipulated by the national standard, and the circulation machinery outside the system is often lower than the level 3. It lags far behind foreign countries in the technology of air separation and screening accuracy, awn removal performance, specific gravity separation of grass seeds, coating and pelletization. Subsurface cryptomatic grassland improvement equipment is a necessary equipment for grassland construction and improvement, and a development and promotion tool urgently needed for grassland maintenance and improvement. In recent years, domestic research and development have been carried out successively. The reliability of herbage harvesting and processing machinery is poor, and the cost has not been reduced to the lowest point, which cannot meet the needs of users. Especially after returning farmland to grassland, high-quality forage grass and alfalfa grass are planted in large quantities. The domestic production quality of urgently needed cutting and conditioning equipment, rapid drying and dehydration equipment, picking and pressing square baling and round baling equipment is still not up to standard. For example, the key technology of picking and tying machine is backward, which restricts the use of grass machinery.
