Reasons for dyspepsia in chicken houses
Nowadays, most farmers raise broiler chickens by using battery cage for broilers. It is convenient and quick to use automatic feeding equipment, and it also saves feed waste. But now, as the summer is about to pass, the autumn will follow, and the rain will be wet. Sometimes there will be a state of indigestion. In fact, there are many factors to consider for this problem.
Feed mold infection, mycotoxins can cause digestive diseases such as oral cavity, intestinal tract, causing indigestion, mycotoxin contamination including feeding mildewed feed, and pollution in processing, transportation and storage. Due to the hot weather, the oil is corrupted due to improper preservation, causing broilers to cause glandular gastritis, muscle erosion and enteritis. Free radicals or reactive oxygen molecules produced by fatty acids can affect their immunity, slow down growth, cause poor pigmentation and cause enteritis. Excessive fat addition can cause lubricative diarrhea.
The nutritional requirements of broilers are relatively high in chicken battery cages . The low content of crude fiber in the feed will result in unbalanced nutrition and excessive crude fiber, resulting in large feed intake of broilers and confusion of gastrointestinal function, which may also cause indigestion. Insufficient energy in the feed The broiler is eating for energy, not enough energy, increasing the feed intake of the broiler, causing other nutrients not directly absorbed and directly excreted, thereby causing indigestion.
It is necessary to know that broilers grow fast, especially the growth of internal organs is 35 days ago; because of the low anti-stress ability of broilers, the environmental requirements are higher. There is no regularity in broiler cage feeding, overeating, or stressing the chicken, or causing the chicken to experience low temperatures at a constant temperature, which can cause indigestion. 60% of broiler chickens are made of water, so there must be sufficient drinking water to meet the needs of the chickens, while some farmers do not pay attention to drinking water sanitation, drinking polluted water or degraded water, causing chicken indigestion.
Main points of construction of broiler chicken cages
With chicken market increasingly competitive, and farmers modernization consciousness gradually improve, more and more farmers to standardization, scale breeding mode, build the henhouse chicken farming became the caged equipment now farmers choose mode of breeding, so farmers in the building of the hen house should be how to build?
1. Site selection: avoid intensive farming areas with better water quality.
2. Feeding mode: cage raising in two stages: "raising young" and "laying eggs".
3. Chicken battery cages construction: it is recommended to raise 15,000 to 20,000 chickens per chicken coop, adopt closed chicken coop and broiler cage feeding equipment, cement floor, wall white cement batch white, automatic drinking water, feeding, ventilation, manure cleaning, etc.
First, the overall layout of the chicken farm:
1. General principles: from the perspective of facilitating epidemic prevention and organizational production. The divisional layout of the field area is the production area, office area, living area, auxiliary production area, and sewage treatment area.
2. Arrangement principle: According to the dominant wind direction, the topography and the flow direction are the living area, office area, auxiliary production area, production area and sewage treatment area. If the terrain is inconsistent with the wind direction, the dominant wind direction is dominant.
Second, the layout of the chicken farm: the overall plan should consider the factors such as the orientation of the chicken house, the spacing of the house, the road, sewage, fire prevention and epidemic prevention. The recommended design of 100,000 large-scale chicken farms is recommended to be arranged in 6 single or double row chicken houses. The single chicken house is 16,000 closed chicken houses. It is equipped with four rows of four aisles and three-tiered ladder cages. Curtains, ventilated windows, mechanical cleaning, mechanical feeding and automatic lighting, automatic drinking water system.
1. Single-roof house orientation: It adopts east-west or east-north (or west) 15 degrees, which is conducive to improving the winter temperature and avoiding summer solar radiation, using the dominant wind direction to improve the ventilation conditions of the house.
2. Chicken house spacing: two types of single-row houses and double-row houses. The spacing of the chicken houses is 10 to 20 meters for brooding and 10 to 15 meters for laying hens.
3. Chicken farm road: The chicken farm road is divided into two types: clean road and dirty road. The clean road is used for transporting feed, chicken and eggs in the field. The dirt is used to transport manure, dead chicken and sick chicken. The two must not be used interchangeably.
What is the Most Important Thing When You Raise Broilers?
In early spring, it is easy to bring discomfort to the chickens in the broiler farms. At this time, the farmers must pay special attention to the rearing and management of the chickens in the broiler farms, and master the necessary broiler breeding techniques to achieve the guarantee of broiler farms. The healthy development of the broilers can lead you a bright feature.
The chickens should ensure that they can drink water within 2 hours after entering the house. For some weak seedlings, artificial drinking can be used to make them drink water. The purpose is to let the chicks learn to drink as soon as possible. The first time the chicks use water at 25°C, add 5% dextrose and 0.1% vitamin C to the water. The waterer should be washed frequently. During the entire brooding period, the drinking water should not be interrupted. From the second day of the brooding, the drinking water should be added. drug.
Broiler Breeding Technology in Chicken Farm
More and more farmers are beginning to develop the breeding industry. Large-scale breeding of chickens requires the use of Poultry Rearing Equipment, such as broiler cages, dung removal equipment and feeding equipment. However, in addition to these breeding equipment, if you want to raise chickens well and bring economic benefits to yourself, you still need certain breeding technology. The following are the key points of broiler breeding technology.
First of all, large-scale farming requires a farm. We need to know where is the best place for chicken farm construction. The selection of chicken farm site is directly related to the epidemic prevention status and economic benefits of chicken farms. According to the size of the breeding scale and the resource conditions, it is necessary to have a clear view of the convenient transportation of the chicken coop, sufficient water resources and guarantee the power supply. Electricity is required for lighting, water supply, temperature supply, ventilation, etc. in the chicken farm, so the chicken farm requires sufficient power supply. Environmental conditions are good and there is room for development.
Chicken coops are places where chickens live healthily. When building chicken coops, attention should be paid to the performance of heat preservation, heat insulation, ventilation and lighting, moisture prevention, ease of production and operation, disinfection and epidemic prevention, etc. At present, there are many types of buildings in chicken coops, which can be divided into two categories: open type and closed type according to different building structures and performances. Closed henhouse is also called windowless henhouse, because it is relatively closed to the outside world, has the function of temperature isolation and shading, and can adjust and control the internal environment of the henhouse. It has greater advantages than open henhouse, but it has high cost and large infrastructure investment.
Broilers for meat are more suitable for high-density feeding, and the feeding amount depends on the effective feeding area of the chicken house and the appropriate feeding density in battery cage for chickens. However, in actual production, the amount of breeding is restricted by many factors. The first is the number of breeders, the second is the feed supply capacity and the source of chickens, and the third is the area of chicken houses. Under the condition that there is no problem with the first two, the feeding amount depends on the area of the chicken coop.
There are two types of ventilation in chicken coops: mechanical ventilation and natural ventilation. There are mainly two types of mechanical ventilation in closed chicken coops, namely, horizontal ventilation and vertical ventilation. These are the key points of raising chickens in the poultry house, hoping to help farmers build a suitable chicken farm.
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.
Method of mixing feed for broiler chicken breeding in broiler cage
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.
- 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.
- 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.
Problems to be overcome in using broiler cage equipment to raise chickens
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.
Advantages of broiler cage equipment
The use of broiler cage equipment is common in many large and medium-sized chicken farms. Except for some farms that are used to free-range, most chicken farms choose to use broiler cage equipment as a device for raising chickens. The broiler cage manufacturers said that the use of broiler cage equipment can collect and manage chickens, save energy, and effectively reduce the incidence of poultry diseases. Let's talk about the advantages of broiler cage equipment.
1. High degree of automation: automatic feeding, drinking water, clearing dung, wet curtain cooling, centralized management, automatic control, saving energy, improving labor productivity, reducing the cost of artificial breeding, and greatly improving the breeding efficiency of farmers.
2. The flock is well-prevented and effective in preventing infectious diseases: chickens do not touch the feces, which can make the chickens grow healthier and provide a clean and comfortable growing environment for the chickens.
3. Save space and increase stocking density: The cage density is more than 3 times higher than the flattening density.
4. Saving farmed feed: caged chickens can save a large amount of farmed feed, chickens are kept in cages, the amount of exercise is reduced, energy consumption is small, and waste materials are reduced. The data show that cage farming can effectively save more than 25% of farming costs.
5. Rugged and durable: The caged broiler complete set of equipment uses hot dip galvanizing process, corrosion resistance, aging resistance, and the service life can be as long as 15~20 years.

Analysis on the feeding management of broilers
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.
How to Scientifically Avoid the Early Death of Chicks?
In many cases, because farmers do not properly grasp the knowledge of scientific feeding and management of chicken farms, it is easy to cause the early death of chicken farms, thus affecting the survival rate of chicks and further affecting the ultimate chicken efficiency. How do you scientifically avoid the early death of a chick when raising in poultry cages for sale.
Drinking water must be timely: especially after long-distance transportation of chicks, be sure to drink water in time, otherwise it will cause dehydration. Take a free drinking method and drink 5% of sugar water for the first time.
The temperature should be appropriate. The chicks are sensitive to temperature and maintain a 35-32 reduction trend within 1-3 weeks after hatching, increasing with age, and decreasing 2-3 times per week thereafter.
The density should be appropriate. if the brood density is too high, there will be more harmful gases in the house, and it will produce worms; the brood density is too small, the brooding area and equipment are not fully utilized, resulting in waste. The average density for flat raising is 20 per square meter, and 40-50 per square meter for cage raising.
