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.
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.
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.
What are the advantages of broiler cages?
Experiments show that the technical advantage of commercial broiler cages is significantly better than the flat to raise. Not only can increase the number of breeding, improve production performance, save production costs, bring significant economic benefits to farmers, but also save land resources, reduce environmental pollution, improve product quality, and create huge social benefits.
In recent years, a more advanced broiler breeding model, broiler cages, is quietly emerging. What advantages does broiler cages have?
The advantages of broiler cages are:
1. High level of automation: automatic feeding, drinking water, decontamination, wet curtain cooling, centralized management, automatic control, energy saving, reduced labor costs, greatly improving the breeding efficiency of farmers.
2. chicken flock prevention, effective prevention of infectious diseases: chickens do not touch the feces, can make the chickens grow stronger, provide a clean and warm growing environment for the chickens, the chickens are healthy and balanced.
3. Compared with the flat raise, the density of the stock is increased by more than 3 times, the utilization rate of the surface area of ??the house is improved, and the land can be saved.
4. Saving feed: meat cages increase the growth rate and feed conversion rate, chickens are kept in cages, the amount of exercise is reduced, energy consumption is less, and waste materials are reduced. According to the experiment, cage cultivation can effectively save more than 25% of the cost of farming. The ratio of feed to meat in net or flat chicken is generally between 1.75 and 1.8:1, while the ratio of caged meat to meat is at least 1.61:1 and the highest is 1.7:1.
5. Reduce the cost of medicines, at the same time can effectively control the occurrence of the disease, because the chicken does not touch the feces, and the use of closed houses, isolated from the outside, reduce the spread of disease; indoor comfortable environment is also suitable for the healthy growth of chicken.
6. Save time: It is convenient for breeding users to manage livestock and poultry, saving more time to deal with other things; using a fully enclosed and fully automated farming mode, two people can manage a chicken house with 3-4 million chickens, which is very economical. Artificial.
Therefore, on the whole, the advantages of cage farming benefit are more and more obvious. In the previous model of land raising and net broiler chicken, the profit of broiler farming was less and less, and many large-scale farming or group with funds, even small-scale Farmers have changed their own chicken houses into cages to further increase the scale and land utilization rate, and improve the breeding efficiency through scale effect.
Characteristics and dimensions of three tiers of broiler cages
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.
Broiler feeding management points of spring
1. Disinfection
The chicks are thoroughly cleaned and disinfected 5 days before entering the site, avoiding corrosive disinfectant such as caustic soda to prevent equipment damage, then fumigation with formaldehyde, and sealing the doors and windows. After 24 hours, the window is ventilated. Personnel must be strictly disinfected to avoid destroying the disinfection effect. The trough and drinking fountains are cleaned and disinfected. After the chicks arrive, the ground is cleaned every day to reduce the stimulation of the respiratory tract by dust and chicken fluff, and the chickens should be disinfected every other day. Several disinfectants can be used alternately, and the vaccination period should be avoided for more than 24 hours.
2. Temperature
There is a temperature difference between the three-layer chicken battery cages in the upper, middle and lower layers, and the lower the outdoor temperature, the greater the temperature difference. Brooding is generally at the highest level, because the highest temperature is the highest, which is conducive to saving heat. The chicks enter the field on the first day, the temperature is controlled at 33 ~ 34 ° C, but also according to the state of the chicks to adjust the temperature. When the temperature is suitable, the flocks are evenly distributed, active and active, and the appetite is strong; when the temperature is low, the neck is constricted and concentrated to the heat source. Squeeze each other, the body trembles; when the temperature is too high, the amount of drinking water increases, the appetite decreases, the breathing speeds up, and the neck feathers are soaked. In the first week, the temperature dropped to 30~C, and then decreased by 2°C every week. The density of three-dimensional culture was large, which was 1~2°C lower than the flattening temperature. It should avoid the heat stress and the food intake decreased.
3. Grouping
Three-dimensional cultured broiler chickens use the whole sports chicks. When the chicks are too dense, they should be grouped in time to ensure that the chicks are evenly weighted. The first group is usually 12 to 16 days old, and the group is too early. Because the body size is too small, it is easy to grow in the cage gap. Drilling also wastes space and wastes energy. The second grouping, at 25 to 28 days of age, adopts the principle of “remaining weak and not staying strong” when grouping, and the important young chicks are placed in the lower layer, and the weak chicks are left behind. In summer, due to high temperature, it can be properly caged in advance. In winter, due to the large temperature difference between the upper and lower layers of the cage, the poultry battery cages time can be appropriately postponed, and one more in the lower cage to reduce the temperature difference between the upper and lower layers.
4. Ventilation
The key to successful aquaculture is ventilation, reasonable ventilation, elimination of harmful gases, temperature control, and reduction of ascites, chronic respiratory diseases and colibacillosis. The density of the three-dimensional farming unit is large, so ventilation is more important. Within 24 hours after entering the farm, the chicks can be ventilated due to the large space of the whole sports. As the age of the chicken increases, the ventilation volume is gradually increased, and the position and size of the air inlet are adjusted. Day, night, cloudy, sunny, spring, summer, autumn and winter. It is necessary to constantly adjust in a timely manner to achieve the feeling of no smell, no glare, no oxygen deficiency and more comfort in the house, to create a good growth space for the chickens, enhance the body's disease resistance and reduce the occurrence of diseases.
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.
How to use broiler cages to raise chickens to reduce mortality
Layer cage manufacturers talk about every stage in the process of broiler breeding, and the later breeding of broilers also needs attention. The growth rate and survival rate of broilers in the later period are directly related to the economic benefits of the farmers, so the fattening work of broilers in the later period must be paid attention to to reduce the mortality of the flock.
1. Ensure proper temperature: When raising broilers in the late stage, the breeder should pay attention to the temperature of the chicken house not to be set too high. The proper temperature is that the chickens are evenly evacuated, the body stretches, and some chickens open their mouths to breathe as an indication, and leave. Near the heat source, the breathing rate is too fast, mostly caused by the high indoor temperature, adjust the temperature in time. In summer, the temperature is too high and the feed intake of chickens cannot increase. Therefore, a suitable temperature can ensure the best conversion function of the feed. In summer, the focus is on heatstroke prevention and cooling. Adequate ventilation: In the later stage, the chicken house is mainly ventilated to improve the small environment in the house and ensure sufficient oxygen circulation to ensure the normal metabolism of the chicken body and the absorption of nutrients. When ventilating, avoid cool breeze blowing directly on the chicken body. Relying on the water curtain to cool down in summer is not very stressful for the chickens that gradually adapt to the wind speed, but the existence of the wind speed will more or less affect the chicken's mobility.
2. Ensure reasonable light management: light work is a very important task in chicken breeding. Farmers know that broiler chickens have a short growth cycle and high feed remuneration. For farmers, excessive weight gain is feed intake. Speed, especially light, is directly related to feed intake, so farmers must control the light in the chicken coop during the later stage of broiler breeding.
3. Pay more attention to the flock of chickens: When the flocks are resting at night, the farmers can observe the flocks frequently, listen to the breathing of the chickens, whether there are snoring, hiccups, or sneezing. If you have the above symptoms, you should think of the respiratory tract. Disease, observe whether there are respiratory symptoms, walk slowly in the chicken coop and listen after turning off the light for about half an hour.
4. Choose reasonable disinfection drugs in broiler cages : Disinfection with chickens is a must to ensure the health of the chicken coop and flocks. When choosing disinfection drugs, farmers are advised to choose a broad-spectrum, efficient, strong, non-toxic and harmless , Low-irritating and non-corrosive disinfection drugs, and disinfect according to scientific and reasonable steps to avoid disinfection errors that affect the health of the chickens.
5. The correct method for disinfection of chickens: When disinfecting, the farmers first prepare the liquid medicine in the disinfection container, start the disinfection from one end of the chicken coop, and walk towards the other end while spraying. The spray nozzle should be upward to make the sprayed liquid drop slowly like a mist. The ground, walls, cages, and ceilings should be sprayed with liquid liquid, and the action should be gentle. Do not disinfect the chickens to prevent the chickens from breathing. To drugs that cause diseases of the respiratory tract.
6. the late-stage medication should be prescribed to the symptoms: in the later stage of raising broilers, the late-stage medication is the stage where the drug cost of the whole batch of chickens rises the fastest, so the medication must be stable and accurate at this stage, and do not blindly administer the medication. In the later stage of administration, you must prescribe the right medicine on the premise of a clear diagnosis. If you miss the best treatment opportunity, the flock may lose control, which is very likely to cause disastrous consequences.

How should the odor of broiler equipment in chicken farms be treated?
If the chicken farm does not clean the chicken manure in the chicken battery cages in time, the odor in the broiler equipment will be very serious, and it will affect the living environment of the chicken. Seriously, it will cause the chicken to become sick and affect the economic benefits. So what should we do?
1 padding deodorization
The sulphur is mixed into the litter to make the pH of the litter less than 7, which can inhibit the generation and emission of ammonia in the feces, reduce the ammonia content in the air of the house, and reduce the odor of ammonia. The specific method is to mix into the litter according to the amount of 0.5 kg of sulfur per square meter of ground, paving the ground.
2 ground odor
Sprinkle a layer of superphosphate on the ground in the house. The superphosphate reacts with the ammonia gas produced in the chicken manure to form an odorless solid ammonium phosphate salt, which can reduce the emission of ammonia in the feces of the house and reduce the odor of the house. The specific method is to evenly spray 350 grams of superphosphate on the ground of every 50 chickens.
3 air odor
The odor in the air is adsorbed by a substance having adsorption such as charcoal, activated carbon, cinder, or quicklime. The method is to use the net bag to load the charcoal and suspend it in the chicken house or properly sprinkle some activated carbon, cinder, lime, etc. on the ground, and the odor in the air can be eliminated to different extents.
The above is how to deal with the odor in the air of broiler breeding equipment. I hope that can help the chickens to better raise their chickens, and they clean up the chicken farm equipment in time to give the chicken a good environment.
Do you Know What’s the new Concept of Broiler Rearing Management?
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.
