The Breeding Density of Broilers

Farming baby chickens for baroilers adopts a combination of whole-house brooding and upper cage brooding. The number of broods per cage is only 25, and there is no problem of crowding. The rearing density of caged broiler chickens is related to the season. The summer stocking density is low, and the winter stocking density can be appropriately increased. Generally, 8-9 pigs are fed in each cage.

Under the conditions of adopting ground litter and keeping the animals online, chickens should be divided into several small groups within the house. The number of chickens per group should be between 200 and 300. When divided into groups, they should be weighed according to their size, physical strength, and public health. The mother carries on, the individual characteristic in each small group must be basically similar. The characteristics of individuals in the group are similar, which is conducive to the even development of the group and helps to increase the survival rate of the chicks.

The use of broiler chicken cage equipment is the development trend of broiler breeding. More and more chicken farmers have begun to try to adopt the mode of broiler cage breeding, which is currently one of the advanced production methods in the broiler breeding industry. It has the advantages of saving land resources, improving breeding conditions, improving production performance, and reducing disease incidence. However, in order to achieve greater economic benefits, it is necessary to overcome its existing problems and maximize the benefits of broiler cages.

The main technical characteristics of broiler cages are as follows: First, the three-layer overlapping cage technology is adopted. The second is to be equipped with an automatic manure removal conveyor belt to clean manure in time and reduce harmful gases such as ammonia and sulfur dioxide in the house. The third is that the entire cage is made of hot-dip galvanized metal anticorrosive materials, and the bottom of the cage is covered with wear-resistant and corrosion-resistant plastic nets, which can effectively reduce the incidence of breast cysts and leg diseases in broilers. Fourth, the chicken house is fully enclosed, relying on air intakes and exhaust fans on both sides of the house to maintain air quality in the house. The staggered installation of incandescent lamps reasonably realizes artificial lighting, and the use of water heaters, wet curtains, and automatic spray devices to achieve temperature and humidity control in the house.

Experiments show that the technical advantages of commercial broiler cages over online breeding are very significant. Not only can increase the number of breeding, improve production performance, save production costs, and bring significant economic benefits to farmers. It can also save land resources, reduce environmental pollution, improve product quality, and create huge social benefits. In line with the development requirements of "scale, standardization, industrialization, and ecologicalization" of the broiler breeding industry, the widespread promotion and application will help accelerate the process of standardization and transformation of livestock and poultry farms, and effectively promote the upgrading of the livestock industry.

Although cage breeding has significant technical advantages over online breeding, there are still some problems with cage breeding technology, mainly in the following three aspects. One is that the initial investment of cage culture is larger than that of online culture, but because the profit rate of cage culture is much higher than that of online culture, the return is quick. Second, the technical requirements of cage breeding are higher than that of online breeding. Because cage houses are closed and fully automated, technicians must not only master breeding management techniques, but also be familiar with the operation of modern equipment. Third, the ventilation requirements of cage breeding are higher than that of online breeding. Because cage breeding is multi-layer breeding, it is more dense than online breeding, which easily causes poor air circulation in the house. Therefore, the above three points are the problems that farmers who use broiler farming cage equipment to overcome.

In the process of developing poultry farming projects in broiler chicken cages, it is hoped that the nutrients contained in each feed that chickens eat are balanced. Otherwise, the flock will suffer from malnutrition, nutrient deficiency or poisoning. Therefore, the feeding formula of the chickens in the automatic broiler cage can be stirred evenly to meet the nutritional needs of the chickens.

 

There are two methods of feed mechanical mixing and manual mixing. As long as it is used properly, satisfactory results can be obtained.

 

  1. The broiler cage feed is mechanically mixed, using a broiler cage mixer. Commonly used broiler cage mixers are vertical and horizontal.

 

The vertical mixer is suitable for mixing powdered feed with a water content of less than 14%. If the water content is too high, it is difficult to mix evenly. This kind of broiler cage mixer requires small power and is easy to maintain, but the mixing time is long (generally 10-20 minutes per batch), which is suitable for chicken farmers and small chicken farms.

 

The horizontal mixer can mix the broiler cage feed evenly in areas with relatively humid climates or when strong viscous ingredients (such as grease) are added to the feed. The machine has a short mixing time, 3-4 minutes per batch, and is mainly used in some feed processing plants. No matter what kind of broiler cage mixer is used, in order to stir evenly, the charging amount must be appropriate. Too much or too little charging cannot be uniform. Generally, 60%-80% of the capacity is suitable for charging. The mixing time is also an important factor related to the mixing quality. The mixing time is too short, but it is not the longer the better. If the mixing is too long, the feed will be mixed evenly and then cause stratification due to excessive mixing.

 

 

  1. Manual mixing is the main method of feed mixing when raising chickens at home.

 

When mixing, be careful and patient to prevent some trace ingredients from clumping and agglomerating. Uneven mixing will affect the feeding effect.

 

When manually mixing chickens in battery cages for broiler, special attention should be paid to some trace components that account for a small proportion in the diet but will seriously affect the feeding effect. Such as salt and various additives. If the mixing is not uniform, the feeding effect will be affected in the light, and the chickens will be poisoned or even die in serious cases.

 

For such trace components, the broiler cage feed must be fully crushed when mixing, and there should be no agglomeration. The agglomerates may be poisoned after being eaten by the chickens. Secondly, due to the small amount of such ingredients, they cannot be directly added to bulk feed for mixing, but should be pre-mixed.

 

The method is: take 10%-20% of the concentrate (which is a large proportion of energy feed, such as corn) as a carrier, and stack it in addition, and press the feed of the next shovel on the feed put down by the previous shovel, that is, go all the way to the feed. The feed is placed on the top, and the feed flows around the center point to form a cone, so that various broiler cage feeds have the opportunity to mix. Repeat this 3-4 times to achieve the purpose of mixing evenly, and the premix is ​​ready. This premix is ​​then added to the whole feed and mixed 3-4 times in the same way to achieve the purpose.

Humidity is closely related to evaporation of water in the chicken body when they are raised in poultry equipment cages, body heat emission and cleanliness of the house are very important. 

When the temperature is high and low humidity, the water in the chicken is not dispersed too much, which may lead to dehydration of the chicks. In addition, due to drying, the dust inside the house is flying, and it is easy to induce respiratory diseases.When the temperature is low and high humidity, the house is cold and humid, and the chick is prone to cold, causing the litter to be wet, and the gastrointestinal disease occur. In general,when the temperature is high and high humidity, the heat in the chicks is not easy to be emitted normally, suffocating, appetite is falling, growth is slow, and resistance is weakened. 

The laying house of the laying hens should be kept dry to prevent bacterial growth and infection, but the relative humidity should not be lower than 40%. Suitable relative humidity is 60% -65% before 10 days old and 50%-60% after 10 days old in your poultry farm equipment house.

The number and size of broiler chickens raised in broiler battery cages is growing at an alarming rate. The density of cultivation per unit area is large, and the management level of the breeders is higher than that of the net culture. In fact, no matter what farming mode and breeding conditions, we manage. The primary task is to manage the chickens so that the chickens have a comfortable living environment so that the chickens do not get sick or get sick.

 

1. Strict control of temperature, ventilation and humidity

Appropriate temperature, light and good ventilation are especially important for the growth of caged broilers. Therefore, in the actual feeding process, it must be strictly controlled. About temperature control. The demand for temperature varies during the different stages of broiler growth. Generally speaking, before brooding, it is necessary to keep warm in advance, and raise the temperature in the house to 26 °C; in the brooding period, the method of high temperature brooding is adopted, and the temperature usually needs to be controlled at about 33 °C, and then it is lowered by 0.5 per week.

 

Control about ventilation. During the brooding period, because the temperature in the house is relatively stable, we usually realize the ventilation and ventilation in the house by controlling the opening and closing of the fan. About the control of humidity. The humidity control in the brooding period is preferably 60-65%. Increasing the humidity in the house can be achieved by placing several water-filled basins in the house and increasing the humidity in the house by evaporation. Increase the humidity inside the house. It is not recommended to sprinkle water on the ground or install nozzles to increase the humidity in the house. The humidity in the breeding house should be kept at 40-60%, and the suitable humidity is conducive to the normal growth of broilers.

Humidity should not be too high or too low. If the humidity is too low, it will cause dehydration of broilers, poor growth of feathers, dry skin, and dust in the air, which may easily induce respiratory diseases. If the humidity is too high in summer, it will cause the evaporation and heat dissipation of the chicken body to be blocked, the feed intake will decrease, the drinking water will increase, and cause heatstroke. If the humidity is too high in winter, the chicken body will lose heat too much, the feed intake will increase, and the feed consumption will increase. This leads to an increase in the ratio of meat to meat and increases the cost of farming.


 
2. Do a good job of cleaning and disinfecting caged houses

The cleaning and disinfection of the chicken house and the chicken battery cages should be thorough, without leaving a dead angle. In particular, it is recommended that the caged broiler has a high breeding density. It is recommended to use spray or fumigation to disinfect. When disinfecting, pay attention to the use of disinfectant. Strictly control the dosage of the disinfectant. In addition, after the disinfection is completed, it is necessary to open the doors and windows in time, and do a good job of ventilation.


 
3. Equipment use

Large and medium-sized chicken farms have advanced equipment, but with advanced equipment, it is not always possible to raise chickens. With the scale and automation, the failure of farming is not uncommon. The key lies in the organic of people and equipment. In combination, the operator must not only be familiar with the principle of the equipment, but also observe it carefully. Because the temperature of the thermostat and the temperature of the house have a certain error, the error value should be adjusted to the minimum, so that the temperature of the house can be adjusted. The temperature at which the chicken is most suitable for growth. In addition, the operator must be proficient in the use of the equipment and the feeding procedures of the chicken at various stages, and can promptly discover and repair the failure of the equipment. Once the equipment is used improperly or the equipment fails, it will Caused huge economic losses.

Analysis of the causes of chicken cold

Cooling is one of the main causes of chicken sickness. There are many cold spots. It is not only the temperature control level or the ventilation of the chickens, but the factors that can cause the chickens to be cold are as follows.


1. During the brooding, the water line is too low, the water pressure is too large, the chicks are drilled into the water cup, the nipple leaks, causing the chicken feathers to be wet; the spray equipment is damaged, the nozzle dripping seriously or the spraying time is long, causing the chicken feathers to be wet.

2. Improper humidification method, only pay attention to humidification, does not consider the temperature of the flock, when the flock performance temperature is low, humidification with a humidifying tube will make the flock cold.

3. The chicken house is not tightly sealed, causing side windows, sewage outlets, chicken outlets, water curtains, exhaust fan outlets, etc., resulting in thief winds, so that the chickens in this area are cold due to low temperatures.

4. After the wind enters the chicken poultry farming equipment from the air inlet, there are obstacles blocking during the pre-warming process, causing the breeze to rebound, and the chickens are swollen.

5. The temperature control is unreasonable; the cooling rate is faster, especially in the cold season, which makes the chicken's cold is more common.

6. Only rely on the temperature indicated by the thermometer, but the chicken's physiological behavior is not taken seriously, resulting in the chickens being cold.

With the progress of the times and the development of science and technology, the genetic breeding technology of broilers has been greatly improved, and the nutritional formulation of chicken feed has also undergone new changes. Broiler breeds are constantly being optimized, and the feeding and management viewpoints of broiler chickens are no longer practical. The broiler breeders at this time need to understand some new ideas for the early feeding and management of broilers.

Do a good job of early feeding chicks, so that the chicks get even and good development in the first week. Changing the way that chickens were fed before drinking water for a period of time before they were fed will become better when the chicks arrive. Change the practice of distributing drinking fountains according to the number of chickens in the past, and increase the number of drinking fountains accordingly so that the chicks can easily find the water in the column after entering the house. If the chicks do not use the trays within the first day of arrival, use clean plastic cloths on the net or spread clean and hard papers to spread the material on the chicks for feeding. The effect is much better than using the trays alone.

In the past, farmers raised broilers in flat greenhouses, and the number of breeding was small. It has been difficult to meet the market demand for chicken product quality. Moreover, the simple raising equipment may cause the disease to be difficult to control, which will inevitably affect the meat output of broilers. However, the broiler cage raising equipment vigorously promoted by the breeding industry can implement automatic fecal removal, so that the broiler is separated from the fecal sewage, achieving less incidence, fast growth, good quality and good benefits. Now the author will talk about the characteristics and dimensions of broiler cages.

Characteristics of broiler cages:

1. The stacked broiler cages produced by high-quality poultry equipment suppliers use a full set of hot-dip galvanizing technology, which is corrosion-resistant and has a service life of more than 20 years.

2. The material of Q235 has great elasticity and is not easy to bend.

3. The high-density breeding saves land, which is about 70% less than the stepped land.

4. Centralized management, save energy and resources, adopt advanced ventilation system, lighting system and automatic control system to fully save energy consumption and improve labor productivity.

5. Save space and increase the feeding density to more than 60 animals/m2.

6. The unique cage door design effectively prevents the chicken from shaking its head up and down when it is eating.

7. The use of conveyor belt to clean the manure to dry the chicken manure into granules, reduce environmental pollution, and high reuse rate of chicken manure.

8. Eco-environmental protection is the most ideal feeding equipment for green chicken and environmental protection egg products.

Broiler cage size:

The cascading broiler cages have three layers and two doors. Each group has a length of 140cm, each group spans 200cm, the number of units is 6, the unit length is 70cm, the unit depth is 70cm, the cage height is 38cm, and the feeding amount is 60.

Stacked broiler cages with four layers and two doors, each group length 140cm, each group span 200cm, unit number 8, unit number 70cm, unit depth 70cm, cage height 38cm, feeding capacity 80.

Each poultry farming equipment supplier provides different sizes of chicken cages, so when buying, you only need to buy according to your own needs, and you don't need to be constrained by the size of the chicken cage.
