The characteristics and superiority of the stepped layer cage

Generally, the layer battery cages can be divided into full-step cages, half-step cages, stacked cages, step-mixing cages and flat cages according to the cage profile or assembly form.


In the full-step layer cage, the upper and lower cages do not overlap in the vertical direction, so that the feces of each layer can fall into the lowermost manure. The manure is then removed from the house by a ground scraper installed in the manure.


The semi-stepped layer cage has a partial overlap of the upper and lower cages, and the overlap can reach 1/2 to 1/3 of the depth of the cage. The top net of the lower cage is made into a beveled angle, which is convenient for installing the dung board, so that the accumulated feces in the upper layer will be dropped into the ditch below the cage under the action of gravity. Most of the currently produced broiler cages and breeder cages use this form. The semi-stepped chicken cage has a small footprint and a higher feed density than the full step.

In the battery layer cages, the chicken cages in each layer overlap in the vertical direction, and each layer of the chicken cage has a horizontal manure device under the bottom net. The chicken manure can be sent to one end of each row of chicken battery cages by a scraper cleaning machine or a conveyor belt type dehumidifier, and the chicken manure can be sent to the outside by a lateral spiral scraper. The small stacked chicken cage can be used for artificial defecation. Mechanization is easy to achieve by feeding, drinking, clearing, and collecting eggs. The advantage of stacked cages is that the density of stocking in the house is high, resulting in a lower average base investment per chicken and high labor productivity. The disadvantage is that the vertical direction ventilation between the layers is poor, the environmental conditions of each layer of the chicken cage are greatly different, and the environmental control requirements of the chicken house are high.


The stacking and mixing layer cages, the upper and lower chicken cages are staggered from each other, the middle and lower chicken cages are all overlapped, and the lower layer chicken cage top is provided with a manure board on the top. The feces can be manually removed from the feces, pushed in, or the feces are dropped or removed using a mechanical scraping board.


Flat-paneled layer cages with only one layer of chicken cages. Each two rows of cages are installed back to back, using a feeding trough, a sink and an egg belt. Chicken manure can fall directly to the ground, and drinking water and septic equipment are the same as stepped chicken cages. Flat cages do not require a corridor, so they have a higher feed density than a full ladder. However, feeding, drinking water, defecation and eggs must all be mechanized. Therefore, the mechanical equipment used must be reliable and depend on electricity. Once power is cut off, the consequences are unimaginable.
