Chickens are the earliest domesticated animals of humans. The number of chickens being bred in the world today exceeds that of humans. It has been reported that the earliest history of human domestication of chickens dates back to 5400 BC. Although domestic human chickens are used for purposes such as watching and cock fighting, the main purpose is to enrich people's meat and to obtain cheap animal protein such as eggs. In the late 1920s and early 1930s, the United States established and developed the world's first automated egg-raising equipment.
In the 1950s, some developed countries have also successively created many modern chicken-raising machines. At the same time, they have made great progress in nurturing improved varieties, full-rate fodder, bird disease prevention, environmental control, and feeding and management. Economic benefits. Since hens have a significant advantage in preventing infectious diseases, lowering production costs, and reducing the occurrence of flock fights, they have been promoted and applied in Europe immediately thereafter. After the 1980s, the United States and the Nordic countries strengthened the research and development in chicken engineering technology, environmental regulation, manure treatment and utilization, aquaculture facilities and equipment, welfare and healthy breeding technologies.
Since the 1970s, China introduced mechanized technology and equipment for caged laying hens. By the 1990s, the model of large-scale caged laying hens has been rapidly promoted. After the reform and opening up, China’s mechanized broilers started to develop and mature, and livestock and poultry breeding Equipment and related environmental control technologies have made progress, such as nipple drinking water equipment, automatic feeding equipment, wet curtain evaporation cooling equipment, livestock large fan and vertical ventilation equipment. There have emerged such ethnic enterprises as Yanbei and Guangxing that can produce a full range of automated chicken-raising equipment. Today, the intensive, large-scale, and mechanized farming industry has contributed its own strength.
Egg cage equipment mainly consists of cage system, feeding system, drinking water system, lighting system, waste disposal system, automatic egg collection system, and environmental control system. Mechanized egg cages can be used to cycle production from hatching, brooding to the final commercial chicken or commercial eggs. Most of the houses are enclosed or semi-enclosed, and the automatic climate control system is used to control the microclimate and lighting inside the house. This allows the house to be balanced throughout the year for high mechanization and automation. Under this mechanized farming method, the breeder can automatically complete the feeding of chickens, the collection of eggs, the removal of feces, the ventilation and ventilation, the temperature and humidity in the house, the time of light intensity, the spraying of disinfectant and the Add soluble drugs to drinking water.
In addition to manual picking up of dead chickens, sperm insemination, daily quarantine, and injection vaccination, all processes can be automated using machines. In the broiler breeding equipment in the past two years, equipment and conveying equipment capable of batching the chickens in the entire house have even appeared, which is a major breakthrough in the broiler rearing technology field in which the feeding period is short.
