Animal husbandry mechanization in developed countries can be roughly divided into three development stages: the first half of the 19th century to the 20th century for part of the mechanical stage, first realized in individual heavy in animal husbandry production machinery, such as forage harvesting in the lawn mower machinery, feed processing of crushing machinery, mixing machinery, animal by-products of milking, shearing machine, etc. In the 1950s, it began to enter the stage of comprehensive mechanization. It not only used complete sets of mechanical equipment in the whole process of feed production and processing, but also began to replace manual operation with machinery in the whole process from feeding to defecation and collection and processing of livestock and poultry products in the livestock and poultry feeding yard. After the 1960s, due to the rise of the feed industry, the further improvement of livestock and poultry epidemic prevention and treatment measures, advanced breeding technology and the development of corresponding mechanization and automation equipment, animal husbandry production entered the factory stage. Inside the corral of factory, has formed the environment suitable for the growth of the livestock and poultry artificial control, with a higher rate of product of livestock and poultry quantitative feeding, new varieties and perfect compound feed to livestock and poultry further get rid of the dependence on the natural environment conditions, breeding density increased significantly, management for livestock and poultry directly contact time is greatly reduced, the quality and quantity of the livestock and poultry products began to be effectively controlled. After the 1960s, some large-scale animal husbandry machinery manufacturers formed cross-industry, cross-system and cross-country joint venture companies one after another. They not only manufacture equipment, but also carry out technical consultation, undertake the development, design and construction of grassland pastures and various livestock farms, provide breeding stock, breeding poultry and feed, and are responsible for guiding mechanized production and technical training. Convenient users, and expand the scope of business.
In the early 20th century, China began to introduce and use the draft mower and rake; From the mid-1950s began to develop and produce matching tractors forage harvester and small feed grinder and hay cutter; From the 1960s began to develop shearing machine and livestock and poultry disease control machinery; In the mid-1970s, the company began to develop and produce rotary lawn mower and finger-plate side rake, etc., and began to develop complete equipment for raising pigs and chickens. Since the end of 1970s, the mixed feed industry and the production of complete sets of feed processing equipment have also been gradually developed.
