Five Broiler Breeding Technology Models And Their Advantages And Disadvantages

We know that the breeding cycle of broiler chickens is short and short-term profits can be achieved. Therefore, many domestic farmers invest in the breeding of broiler chickens or broiler breeder chickens. However, there are many production technology models for broiler chickens. How to choose for breeding?

1. Thick bedding ground free-range culture technology model

Because the breeding period of broiler chickens is relatively short, thick bedding is often used in the breeding method, that is, thick bedding is laid on the ground, and the bedding and feces are removed at once after being put out of the slaughterhouse. The advantages of free-range farming on the ground are simple equipment requirements and low investment. The disadvantages are that the breeding density is small and the chickens are not conducive to disease prevention and control if they come into contact with animals. Generally, the feeding density should be controlled at a body weight of 25kg/㎡.

2. Online flat cultivation technology model

Online flat farming means that the chickens are off the ground and move on mesh sheets made of metal or other materials. It is also called full-slat farming. A manure leakage floor of plastic mesh, metal mesh or plastic-coated mesh is laid on the F mesh (grid). The floor is generally about 20 meters above the ground.

60cm. The chickens live on the slats, and the feces falls under the net. The chickens are not in direct contact with the feces, which is beneficial to the prevention of disease in the chicken farm. This kind of breeding method has the highest breeding density among flat breeding, and 4.8 breeder chickens can be raised per square meter, so the production capacity per unit space is high.

3. Mixed ground feeding technology model

The so-called mixed ground breeding means that the chicken house is divided into two parts: the ground and the net. The ground part is padded with thick bedding. The online part is Slatted trellis structure. The ratio of the bed surface to the litter floor of the rice strip scaffolding structure is usually 6:4 or 2:1, and the layout of the house mainly adopts "two high and one low" or "two low and one high". "Two high and one low" means laying slats along the wall, with half of the slats laid against the front wall and half against the back wall. 

This is the most commonly used broiler raising method at home and abroad. The egg-laying boxes are placed on the outer edge of the slats and are arranged perpendicularly to the long axis of the house. One end is placed on the edge of the slats and the other end is suspended above the litter ground, making it easier for chickens to enter and exit the egg-laying boxes and reducing the floor space. Using this mixed breeding method of slatted scaffolding litter and ground, the egg production and egg fertilization rate of breeder chickens can be higher than that of the all-slat type breeding method, but the stocking density is slightly lower. Meat breeds are raised per square meter. 4.3 chickens.

4. Cage technology model

Broiler chickens and broiler breeders rarely use cages abroad, but in some domestic enterprises, many people use cages to raise broiler breeders. In particular, it is common for yellow-feathered broiler breeders to use cage technology. The production of broiler breeders adopts cage technology. Its advantages are:

1. Increase stocking density. The breeding density of three-dimensional cages is more than three times that of flat cages, and the number of laying hens per square meter can reach more than 17.

2. Save feed. When chickens are raised in cages, the amount of exercise is reduced, less energy is consumed, and waste of materials is reduced. Artificial insemination of breeder chickens allows fewer roosters to be raised.

3. Chickens do not come into contact with hard manure, which is conducive to epidemic prevention of chickens.

4. The eggs are relatively clean and eggs outside the nest can be eliminated.

5. There is no litter problem.

However, there are many disadvantages to using cage technology:

1. The number of eggs produced may be less than that of flat-rearing animals.

2. The investment in breeding equipment is relatively large.

3. The proportion of blood-spotted eggs is high, the egg quality is slightly poor, and the hatching egg qualification rate is low.

4. Sudden death syndrome in caged chickens affects the survival rate and egg production performance of chickens.

5. The appearance of culled chickens is poor, the bones are brittle, and the sales price is lower.

6. Cage-raised broilers are prone to breast cysts and have low slaughter rates.

For commercial broiler chickens, due to their rapid growth and development, breast cysts are easily caused, so this breeding technology is rarely used in recent years.

5. Application of all-in, all-out system in broiler production

The so-called "all in, all out" means that chicks of the same age are raised in a chicken coop or farm and sold in the same batch after they are raised to a certain age. The advantage of this production process is that after the chickens are raised at the same time, the chicken house can be thoroughly cleaned, cleaned and disinfected, and the chicken house can be left empty for a certain period of time to cut off the circulating infection of the source of the disease, which is conducive to the epidemic prevention of the entire chicken farm. , reduce the occurrence of diseases. Because the breeding time is relatively concentrated and the feeding volume is large, a high level of feeding and management technology is required to ensure that the growth and development status of the entire chicken flock is basically inconsistent.

Otherwise, the individual weight differences of broiler chickens will be too large, affecting the simultaneous slaughter. For large-scale broiler chicken farms that implement all-in, all-out, there are often a large number of chickens on the market at the same time, and the working capital takes a long time, so the market risk is greater. In addition, due to the short breeding period of broiler chickens, it usually only takes 6 to 8 weeks to raise modern broiler chicken varieties to reach slaughter weight. Even if local broiler chickens are raised, the growth period generally does not exceed 120 days. 

Therefore, in the production of broilers, the "all in, all out" production process model is mainly selected. For large-scale broiler farms, in order to reduce the pressure on capital turnover and achieve a balanced launch of products, it is recommended to adopt partitioning or building all in and all out. , that is, the chicks are introduced in batches and the products are put on the market in batches.
