layer chicken cage production requirements

Generally, the cage is started from 18 to 20 weeks old, and the cage is eliminated when it is raised to 72 weeks of age to complete a production year. Therefore, in the good environment of the chicken house, there must be a properly structured chicken cage to enable the laying hen to achieve its highest production efficiency.

The size and size must be able to meet its certain area of ​​activity, feeding position and height. At the same time, in order to allow the laid eggs to roll out of the cage in time, the bottom of the cage should have a certain inclination. According to the above requirements, the arrangement must consist of a number of small single cages. Each monomer cage has 2, 3 or 4-5 chickens.

The size of the single-cage cage is generally 445-450 mm from the front, 400 mm from the rear, the slope at the bottom of the cage is 9-10 degrees, the depth of the cage is 310-350 mm, and the egg collecting trough extending out of the cage is 120-160 mm. . The cage width depends on the feeding position. The feeding position of each chicken is 100-110 mm, the two chicken cages are 250 mm wide, the three chicken cages are 300 mm wide, and the 4-5 cages are 420-450 mm wide.

Monomer cages are manufactured and installed in two forms, integral and assembled. The monolithic structure is a unitary unit of several units, which is characterized by convenient installation, but consumes materials, is difficult to handle after being manufactured, and is easily deformed. The assembled type adopts an integral cage, and the single cage is manufactured and installed in two forms, namely, integral and assembled. The monolithic structure is a unitary unit of several units, which is characterized by convenient installation, but consumes materials, is difficult to handle after being manufactured, and is easily deformed. The assembled type adopts the whole cage frame. When the whole cage frame is installed, each cage net is hung on the ground. It is characterized by neatly installed, replacement and maintenance forces. In actual production, assembly is more common.

The cage nets of the single cage are generally made by cold drawn steel wire spot welding, but the functions of each cage net are different, and their material thickness and mesh size have different requirements.

The side net and the rear net are mainly used as the spacing of the cages, and the wires having a diameter of 2 to 2.5 mm can be distributed into a horizontal grid. The warp direction is arranged in the outer case with a spacing of 100 to 200 mm; the weft is arranged with the filaments on the inside with a spacing of 30 mm, which prevents the chickens from being trapped in the cage.

The bottom net not only has to bear a certain weight, but also has to drop the feces and not drop the eggs, and has a certain elasticity, so that the eggs are not easy to break when they are laid, and the chickens have a certain sense of comfort when they are active. Therefore, the straight diameter is 2.5~ 3.0 mm wire, distributed in vertical grid. The warp threads are arranged on the surface with a spacing of 22 to 25 mm; the weft threads are arranged under the bottom with a spacing of 50 to 60 mm, so that the eggs can smoothly roll out along the warp direction.

The width of the cage door depends on the width of the single cage. Generally, it is welded into a vertical fence with a wire of 3 mm in diameter with a pitch of 50 to 60 mm. The cage door is 400 mm high, and its lower edge should be 50-55 mm away from the bottom net to leave a gap for laying eggs; or a guard egg plate can be placed 50 mm from the lower edge to extend the cage to prevent the egg collecting tank from being inside. Eggs are eaten by chickens, and chicken manure is drained into the trough and sink.

In addition, in order to extend the service life of cold drawn steel wire cages, anti-corrosion measures such as galvanizing can be used.
