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.
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.
The efficient breeding of broilers can not be separated from the rich chicken breeding experience of broiler farmers, but also can not be separated from the scientific use of broiler breeding techniques, and the efficient feeding of broilers is an important guarantee for the success of broiler breeding.
Insist on the advanced breeding method to leave the ground chicken, can be raised on a net bed. The nets are raised flatly, and the meshes are of a moderate size, so that chicken eyes can't leak through the mesh, and chicken droppings can be leaked. You can make or purchase a commercially available plastic net bed. As a result of leaving the ground, the pathogen has lost a breeding hotbed and can effectively control the occurrence and spread of chicken coccidiosis and ferret disease. The implementation of off-site feeding is mainly used to prevent ground infection, convenient and feasible, and strong operability.
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.
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.
A reasonable structure of the chicken house can provide a good living environment for the chickens including of equipment used in poultry farming, so that they can fully exert their production potential. Therefore, in addition to understanding the physiological characteristics of the chicken itself, the chicken house must be reasonably planned and constructed.
First, chicken layout considerations
1. The site should be chosen away from the residential area, convenient transportation, and far from the road.
2. The terrain is dry and sunny. As far as possible, it is not blocked in winter, no wind in summer, and no water after rain. Large area, leaving room for development
3. Rich in water resources, no pollution, easy to access, sufficient power and protection
4. The structure of the house is practical and economical. It not only saves funds but also saves energy as well as about chicken cages for sale. Its orientation is in line with local natural and physiological conditions. It is well lit, easy to ventilate and easy to operate. It is good for summer heatstroke and cool, and winter is good for heat preservation and cold protection.
5. The layout of the premises should be reasonable, so that the production area is separated from the non-production area. The non-production area and the water source are in the upwind direction of the chicken farm. The dirty road and the clean road are separated and do not cross. The manure field is located in the downwind direction of the chicken farm, and the brooding Separated from the breeding house, the brooding house is located in the upwind direction of the chicken farm.
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.
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.
① Production performance: The higher the production level, the greater the water requirement of the chicken. For example, adult chickens drink more water than chicks; among chickens of the same weight, young chickens develop water deficiency faster than adult chickens; laying hens drink more water than non-laying hens.
② Feed structure: Some feeds such as rye, bran and certain minerals such as table salt can cause chicken loose stools, so the water requirement increases. Excessive protein levels in the diet can increase drinking water. Because too much nitrogen in the chicken must be excreted from the kidney, and the chicken has the worst concentration of urine, it is necessary to increase the drainage to excrete more nitrogen, thereby increasing the water requirement. The increase of crude fiber content in the feed and the increase in the amount of feces in the chicken also increase the water requirement.
③ Ambient temperature: Under the production conditions of broiler cages, due to changes in the ambient temperature, the amount of water consumed by the chicken has changed significantly. High temperature (above 30℃) usually increases the amount of drinking water. When the ambient temperature increases by 1°C, the amount of drinking water can increase by about 7%; when the temperature is low (below 10°C or less), the amount of drinking water decreases. When the temperature of laying hens is increased from below 10℃ to above 30℃, the drinking water volume can be doubled. In addition, the temperature of drinking water can more affect the amount of water consumed by chickens. Chickens like to drink cold water instead of drinking water above ambient temperature, and refuse to drink water above 45℃.
④Water quality: When using broiler cages to raise chickens, chickens have strict requirements on water quality. There are fewer impurities in the water, and the pH is between 6.0-8.5. If there are more impurities in the water, especially when the water contains more soluble minerals, it will cause the chicken's palatability to the water to be reduced, thereby reducing the amount of drinking water. In addition, the use of certain drugs in water can also reduce the amount of water consumed by chickens. Therefore, chickens should be given fresh, cool and clean drinking water.
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.
