Analysis of the advantages and disadvantages of ground breeding chicken and cage breeding chicken.

Generally speaking, there are two ways to raise chicken, one is flat-raising and the other is cage-raising. Flat-raised chicken and caged chicken can be subdivided. Each has its own advantages and disadvantages. Choose the breeding method for the specific conditions of the farm. Below, let’s take a look at the advantages and disadvantages of these two breeding methods.

1. Flat chicken
Flat raising means that the chicken move on a flat surface. Flat rearing can be divided into ground free-range rearing, online flat rearing and mixed ground rearing. The flat-raising chicken house has a small breeding density, a large construction area, and a relatively high investment. At present, the general broiler chickens in my country use this breeding method.
Ground free-range rearing is also called thick bedding ground rearing. Lay thick litter directly on the ground or cement floor. Chickens live on the litter. Broilers often use this form.
Advantages: simple equipment requirements and low investment.
Disadvantages: The stocking density is small, and the chickens are exposed to feces, which is not conducive to disease control.
The off-the-ground net flat raising means that the flock of chickens leave the ground and move on a mesh made of metal or other materials. On the mesh (grid), slatted floor such as plastic mesh, metal mesh or plastic-coated mesh, etc., the floor is generally about 1.2 meters above the ground (to facilitate the extraction of chicken manure).
Advantages: chickens live on slats, and their feces fall under the net, and the chickens do not directly touch the feces, which is conducive to disease control; the highest stocking density, 4.8 breeding chickens per square meter.

Disadvantages: relatively high investment, relatively inconvenient to dig out chicken manure.

Mixed ground breeding means that the chicken house is divided into two parts, the ground and the net. The ground part is bedding and the net part is a slatted scaffold structure. The ratio of the bed surface of the slatted scaffold structure to the litter floor is usually 6:4 or 2:1, and the layout of the house mainly adopts “two highs and one low” or “two lows and one high”. “Two high and one low” is currently the most widely used broiler breeder breeding method at home and abroad. Foreign layer breeders also mainly adopt this breeding method, that is, laying slats along the wall, half of the slats are laid against the front wall, and the other half is against the front wall. Laying the back wall. The laying boxes are on the outer edge of the slats, and the row direction is perpendicular to the long axis of the house. One end is framed on the edge of the slats, and one end is suspended above the litter floor, which is convenient for chickens to enter and exit the laying boxes and reduce the floor space.
Advantages: The egg production of chickens and the fertilization rate of breeding eggs are both higher than that of the full-slat type breeding method.
Disadvantages: The rearing density is slightly lower, only 4.3 broiler breeders per square meter can be raised.

2. Caged chickens
Cage raising means raising chickens in cages welded with wire. Different types of chicken cages are designed according to the type, gender and age of the chickens, including chicken cages, growing chicken cages, layer cages, breeder cages and rooster cages.

The main advantages of caged breeding:
(1) Increase the stocking density. The density of three-dimensional cages is more than 3 times higher than that of horizontal cages, and the laying hens can raise more than 17 per square meter.
(2) Save feed. The chickens are kept in cages, so the amount of exercise is reduced, the energy consumption is less, and the waste of material is reduced. The implementation of artificial insemination can reduce the proportion of roosters.
(3) The chicken does not touch the feces, which is conducive to the epidemic prevention of the chickens.
(4) The eggs are relatively clean, which can eliminate the eggs outside the nest.
(5) There is no litter problem.

The disadvantages of caged chicken:
(1) Egg production has been reduced compared with that of flat rearing.
(2) Investment has increased relatively.
(3) The proportion of blood-spotted eggs is high, the quality of the eggs is slightly poor, and the pass rate of breeding eggs is low.
(4) Cage chickens are prone to sudden death syndrome, which affects the survival rate and laying performance of chickens.
(5) The appearance of eliminated chickens is poor, the bones are more brittle, and the selling price is lower.
