poultry layer cages

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 have no shortage of 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 commercial ladder egg-feeding equipment.

In the 1950s, some developed countries also successively created many modern chicken-raising machines. At the same time, they also made great progress in nurturing good breeds, full-rate feed, poultry disease prevention, environmental control, and feeding and management. Economic benefits. Since hens have a significant advantage in preventing infectious diseases, reducing production costs, and reducing the occurrence of flock fights, they have been applied and promoted in Europe immediately afterwards. 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.

With the promotion of mechanization of the chicken industry throughout the country, stepped and stacked layer cages have been improved and promoted, and the level of mechanization has been greatly improved, while other types of cages have gradually been eliminated from the market. In the current industry, semi-stepped styles are also called stepped or A-type cages, and stacked styles are also called overlapping or H-type cages. The semi-stepped cage has certain advantages in ventilation and lighting, and the equipment can realize the combination of mechanical automation and manual operation, so it can also deal with emergencies such as power outages. The stacked cages have a significant effect on breeding density. Its superiority, with the improvement of rural power facilities and the development of automation equipment, has also been widely used.

At present, the common stepped egg cage forms: the angle between the bracket bracing and the ground is reduced to 650-750. The larger central area of the cage system facilitates the vertical and vertical flow of the air, so the ventilation effect is better; the lower cages are offset more outwards in the vertical direction, so that the chickens in the next two cages more fully reach the aisle. Light source, so the lighting effect is good. Remove the shroud from the top of the middle cage cage. The overlap of cages in the vertical direction is only 1/3 of the depth of the cage, and 1/3 of the cage near the front net is the feeding area for chickens. The possibility that chickens will produce droppings of feces in this area will fall to the lower layer. Smaller, a small amount of feces will fall off the front of the cage block, so do not need to install the dung.

Ladder type egg culture equipment cage type consistent. As the lower layer is not installed with a shroud plate, the top net of the middle and lower layer cages can be designed to be horizontal, so that the chicken cages in each layer are exactly the same, which leads to the standardization of the cage net and the assembly of the cage system.
