When we use chicken farming equipment, there is a chicken house environment control device on the egg cage to achieve reasonable regulation of the temperature and humidity of the house. In order to ensure the growth of chicks, etc., the regulation of chicken house temperature should be within a reasonable range. The temperature control of the chicken equipment is different in the temperature requirements of the chicken at different growth stages: the chicken just out of the eggshell needs 32 degrees Celsius to 34 degrees Celsius. Later, as the age of the week increases, the temperature gradually decreases, that is, it decreases by about 2 degrees Celsius for every one week of increase, and is maintained at 21 degrees Celsius to 23 degrees Celsius by the sixth week. Temperature is related to the healthy growth and feed utilization of broilers. If the brooding temperature is too high or too low, it will affect the yolk absorption, which will reduce the immunity of the chick and cause infection. If the temperature is too high, the drinking water of the chicken will increase, the temperature of the feeding will be reduced too low, the chicken will increase the feed consumption to maintain the body temperature, reduce the feed compensation, raise the chicken, and raise the priority of the chicken equipment to the temperature.

1. The brooding method of heating equipment flue heating is more suitable for small and medium chicken farms. Bricks or adobes are used to form flue pipes. Larger brooding rooms can use long flue. Smaller brooding rooms can use field-shaped surrounding flue. When designing flue, the diameter of flue inlet should be larger. It should be gradually reduced to the outlet, so as to facilitate the circulation of heat and smoke, and prevent smoke from falling.

 
2. Ventilation equipment The enclosed house must be mechanically ventilated to solve the problem of ventilation and cooling in summer. There are two kinds of mechanical ventilation: air supply type and exhaust type. Air supply type ventilation is to use a fan to forcibly send fresh air to the house to form a positive pressure inside the house to remove the dirty air. The exhaust type ventilation is to use a fan. The dirty air in the chicken house is forcibly extracted, so that the negative pressure is formed in the house. The fresh air equipment will raise the chicken equipment and mainly introduce what enters the house through the air inlet.

3. Water supply equipment Flat chickens can use the hanging tower type automatic water drinker. The water drinker is suspended from the ceiling by a rope, and the water inlet hose is connected to the main water pipe. The incoming water flows through the control valve. Drinking trays are both hygienic and water-saving.

4. Egg laying equipment Breeding broiler breeders or flat laying hens can use double-layered egg laying boxes. In addition to flat net culture, bred chickens are often used in overlapping or stepped brooding cages. Laying hens are basically caged. Cultivating cages and caged chickens can make full use of space, increase feeding capacity, good sanitation, easy epidemic prevention, save feed, high cleanliness of eggs, and convenient management of chickens. Small group breeding cages can be equipped with curtain shade at one end of the cage to create a quiet environment for laying eggs for hens.

The most important thing to raise chickens is to pay attention to ventilation management in poultry cage equipment. The same is true for raising chickens. Some people raise chickens very well. Some people raise chickens and often have various problems. In fact, when the season changes, the external temperature difference is large. If you do not pay attention to ventilation management, the chickens are very prone to colds, which induce respiratory diseases. Therefore, chickens must pay attention to ventilation, otherwise there will be a lot of toxic gases in the chicken house. So how should we improve management?

1, Hazard

If the inside of the chicken house is not ventilated for a long time, if we walk inside, we will feel dizzy and lack oxygen when we wait for a long time. This is not only a problem of insufficient oxygen, but a lot of toxic gases are present in it. For example, if chickens pull feces, ammonia will be produced.

2, adsorption

For example, activated carbon, this is a certain adsorption. In addition, like lime, cinder is also adsorbent, you can use the net bag to install some hanging in the chicken house, in addition, you can also spread some directly on the ground of the walkway, can play a certain role in the adsorption of toxic gases. effect.

3, ventilation

In fact, the best way is to do ventilation, while taking some warming measures, while venting, neither affecting the temperature, but also make the air better. When burning charcoal, be sure to pay more attention to ventilation to avoid poisoning. There are also some heated stoves, the pipes should be discharged directly to the outside, and there should be no leakage.

4, clean up the feces

Many toxic gases come from the faeces, so it is very important to clean up the faeces quickly. The faeces will be discharged for too long and the toxic gases will be more.

5, density

Be sure to pay attention to the density when raising chickens, not too crowded. If you are raising it in a cage, don't put it too tightly, pay attention to proper ventilation, so that the air can be better.

6, Greening

If you are around the chicken house, you must pay attention to greening. In this case, the improvement of the air can also help to make the ecological environment better. Ventilation is very important for chicken farmers to ensure that the air inside the house is fresh and the bacteria are not so fast. But in the winter, many chicken farmers will worry about the problem of ventilation and insulation. If there is too much ventilation, the temperature will drop, but it will not be ventilated. The taste inside is very unpleasant. There are many toxic gases, such as ammonia. , carbon dioxide, methane, etc.

If the chicken lives in such an environment for a long time, the physical condition is not good. As long as you master the above six points, the ventilation of the chicken house can be solved.

In recent years, many diseases have been found to be associated with the use of chicken layer cages, also known as cage disease. The following are common:

1. Cage laying hens fatigue (tiredness) The symptoms of this disease are increased bone fragility, muscle relaxation, sagging wings, difficulty standing, and finally dehydration and weight loss. This disease occurs mostly during the peak of egg production, and the incidence rate is related to various factors. The cause is mostly related to the metabolism of calcium. Take the afternoon to supplement the granular calcium, and ensure that the daily intake of 3.3-4.2 grams of calcium, can effectively prevent the disease.

2. Fatty liver syndrome is also called fatty liver hemorrhagic disease. This disease is the result of excessive fat deposition in the liver of sick chickens. According to the study, it is a metabolic disease, which is closely related to nutrition, but it occurs mostly in cage chickens. The mortality rate is about 1.7%, and the hot area is about 4.6% or even higher. The main loss is a significant drop in egg production. The incidence is mostly in the peak period of egg production, stress period and high ambient temperature. When the disease occurs, the egg production rate can be reduced by 10%-40%, or the high-yield chicken with good body condition suddenly dies. Limiting feeding and reducing energy intake, while increasing the levels of choline, vitamin B::, vitamin B: biotin, methionine and selenium in the diet will help prevent this disease. At the time of onset, vitamin E10000 international unit, vitamin B, 12 mg, choline chloride 1000 g, and inositol 908 g were added to each ton of feed, and the condition was relieved even after feeding for 2 weeks.

3. Panic disorder is also called hysteria. When the disease occurred, the flocks were stunned in the cage and panicked. Initially, a few chickens developed symptoms and eventually spread to the entire flock. The incidence of light chickens is generally higher than that of medium-sized chickens, and is not affected by chicken age, but the loss of laying hens is the largest. The onset time of the laying period is mostly 36-37 weeks old or the peak of egg production. There are many factors causing the disease, such as noise, flashing lights, broken water, excessive density, poor ventilation, clothing of the breeder, and excessive magnesium in the diet. The mitigation measures are to first relieve the cause, followed by 200 grams of niacin per ton of diet, with red light.

With the rapid development of the chicken industry, poultry farming equipment is also becoming more and more perfect. Although chicken equipment saves us a lot of time and energy, we also need to pay careful attention.

1. Prevention and control measures for chicken Newcastle disease

Newcastle disease virus is ubiquitous. As long as there is a Newcastle disease virus in the place where chickens are raised, the chickens can still perform very healthy and have good production performance under poisonous conditions. However, as long as the climate is mutated, management is extensive, malnutrition, fright, crowded, transferred, broken, vaccination and other stress factors appear; the body's resistance is reduced, the flock will immediately develop symptoms, with mild or no respiratory symptoms. The egg production rate is slowly decreasing or rapidly decreasing, ranging from 10% to 60%, or even more. Despite the intensive intensive immunization measures taken by Newcastle disease in the country, including the repeated use of attenuated live vaccines and oil-inactivated vaccines, and even the use of imported vaccines, the incidence of Newcastle disease has remained high, especially atypical. Newcastle disease is still one of the major infectious diseases currently affecting the healthy development of the chicken industry.

2. Prevention and control measures for avian influenza

Avian flu can occur all year round, but the incidence rate is higher in winter and spring, which is related to the strong resistance of the pathogen of the disease under low temperature conditions. In immune stress, the virulence gradually increases, new The strain has been increasing. Highly pathogenic avian influenza generally has no characteristic symptoms. The acute hemorrhage changes accompanied by high mortality, up to 100%. The acute onset is yellowish thin feces, cocks are bright red, malformed eggs are increased, and wetness Voice, tracheal ring bleeding, pancreatic marginal bleeding, glandular papillary hemorrhage, green skin infection of the stomach and stomach, severe intestinal bleeding, rectal collateral cord hemorrhage, severe follicular necrosis, milky white sticky secretions or yellow in the fallopian tube Cheese-like, young chickens can see bursal bleeding. The main symptoms of low pathogenic avian influenza: no significant increase in mortality, cough, sneezing, tearing, edema of the head and face, cockroach cyanosis, loss of appetite, mental disorder, diarrhea, decreased egg production rate, the most common lesion is ovarian degeneration , follicular congestion, congestion, rupture and manifested as yolk degeneration, follicular congestion, hemorrhage, rupture and manifested as yolk peritonitis. Because of the widespread presence of avian flu infections and the mutability of viruses, it becomes very difficult to control.

3. Daily considerations

In daily management, we must strictly sterilize chicken houses, venues and all means of transport and drinking utensils, 1 or 2 times/d; strengthen immunization, establish monitoring systems, strictly implement immunization procedures, and take precautionary measures to prevent or Emergency immunization. Regular antibody testing, by detecting antibodies, can know the vaccine immune effect, determine the immunization time, whether the flock is infected with wild poison and so on. In the end, in daily life, the flu virus that lives in the poultry house will be killed.

A reasonable chicken battery cages house can provide a good living environment for the chickens to make full use of their production potential, so in addition to understanding the physiological characteristics of the chicken itself, the chicken house must be reasonably planned and constructed.

address

It should be chosen away from residential areas, convenient transportation, far away from the road, sunny, large area, leaving room for development, rich in water resources, no pollution, good lighting, easy to ventilate, easy to operate, summer is good for heatstroke prevention, winter is good for heat preservation Cold weather avoids urban polluted areas and adopts appropriate environmental protection measures to minimize environmental pollution.

The building type of the chicken house is divided into closed and open type. The enclosed chicken house has no windows around it. It is artificially illuminated and mechanically ventilated. It is an energy-consuming chicken house. The climate is easy to control and easy to manage. The open house is a window house, an energy-saving house that uses the natural resources of the outside world. Generally, no power ventilation is required, and artificial lighting is fully utilized. The disadvantage is that it is greatly affected by the outside world.

The purpose of ventilation is to exclude the dirty air in the house as much as possible: the introduction of fresh air, keeping the air inside the house fresh, cooling, dispersing and reducing the body temperature of the chicken, which is the first factor to measure the environment of the house. There are two kinds of natural ventilation and mechanical ventilation.

Natural ventilation: no special equipment, no power, low capital cost, low maintenance cost, simple and easy to operate, if it can be reasonably designed, installed and managed, it can receive better results, and the cold season is limited by heat preservation. good.

Mechanical ventilation: used in enclosed chicken houses and semi-enclosed chicken houses. It relies entirely on forced ventilation of fans. Ventilation and ventilation are thorough and rapid. The disadvantages are large investment and high cost.

The cage mode of broilers has long been common and is growing in size. The breeding risk of caged broiler chickens has also changed from the original disease prevention and control to the epidemic prevention and control, focusing on market changes and turning into focus on feeding management, environmental protection and food safety. So what can we do to minimize the risk of farming?

Broiler battery cages are essential in daily production and feeding management. The nuances are effective, and the owners of the farms have paid great attention to them. For example, the first week of temperature, humidity, temperature difference, ventilation, food, boiling water, Salmonella prevention and control management; the second week of temperature, ventilation, temperature difference, respiratory disease prevention and control, control of light control materials, etc.; third week Ventilation, intestinal health, control and light control management; ventilation and control management in the fourth week; ventilation and fattening management in the fifth week. However, it is not enough to raise caged broilers. It is necessary to pay attention to the following points:

1. Weekend weight determines the growth potential of the flock, and whether the weight is good or not at the weekend is determined by the following aspects.

1.1 Temperature, temperature difference, humidity, ventilation and other indoor environment control and management.

1.2 The control of Salmonella must be controlled by the most sensitive drugs in the area.

1.3 Control of mold and mycotoxins. The broiler liver in one week is most afraid of mycotoxin damage, and it will be damaged for a lifetime. Within a week, broiler control molds must not use inferior mold remover. Be sure to use a powerful fungus that can kill mold, protect the liver, and relieve the effects of mycotoxins.

1.4 Promote the growth of the chicken's immune system within a week, which determines the health of the broiler for 38 days.

1.5 Adenomy gastritis and intestinal health care. It can directly affect the feed intake and growth rate in the middle and late stages. So caged broilers, the first week of feeding is very important, just like the foundation of a high-rise building.

2. Feeding management of broiler in the middle

The management of broilers in the middle of the period is based on the health of the liver and intestines. However, cage broilers have some areas of concern in specific practices.

2.1 Must be strictly controlled

There is no loose space for caged broiler chickens. Strict control not only gives the gastrointestinal emptying time, but also the chickens will compete for feeding when concentrated feeding. This is the only opportunity for caged broiler chickens to exercise.

2.2 Vertical high-density cage mode requires higher quality feed and greater ventilation to ensure stable liver function

Cage broilers must pay attention to liver care by periodically activating liver tissue activity and improving liver function. People who used to breed in the past know that "cultivating chicken is to raise the intestines, management is to control ventilation." Now caged broilers must not only raise the intestines, but also raise the liver. This is one of the key points in the cage broiler to make money.

In order to truly achieve the expected economic benefits, caged broilers must pay attention to the following issues:

1. Try to use three layers of overlapping cages to raise broiler chickens in large scale. Specifically, it is guaranteed to be in the cage from the first day until the slaughter. This will not only facilitate uniform feeding management, but also increase the density of feeding. To improve the efficiency of land use.

2. The phased expansion of cages is especially critical. Specifically, in the first 21 days of the breeding period, the method of brooding in a small area should be adopted. After 21 days, the group should be gradually expanded.

3. Pay attention to the enhancement of the changes to the cage material and the corresponding structure, which can greatly reduce the incidence of broiler cysts.

4. Special attention should be paid to the design of the cage front net during the brooding period. In general, the pear-shaped design is used to provide an adjustable baffle to facilitate the feeding needs of the broiler.

5. Scientifically design feed formula based on the nutritional needs of caged broilers. The feed formula of caged broiler chickens should be scientific and reasonable, especially to pay attention to the vitamin content in the feed formula to meet the nutritional needs of caged broilers.

6. Cage broiler houses must be fully enclosed, so an exhaust fan should be installed to facilitate the discharge of air from the house and enhance the air circulation of the house.

In addition, since artificial lighting is not used for natural lighting in chicken houses using broiler battery cages, special attention should be paid to temperature control. Once the temperature in the house is too high, the wet curtain should be installed in time to reduce the temperature. If the temperature is too low, especially in the cold winter, the temperature in the house should be controlled within a suitable range by artificial heating.

In our daily chicken raising process in poultry farming equipment, we are always afraid of insufficient nutrition. If the laying hens are malnourished, the egg production will decrease, or soft shell eggs and thin shell eggs will appear. However, only a very small number of farmers have learned that if the laying hens have excess nutrients, they will also cause their egg production to drop, and even cause the death of laying hens, and how to prevent overnutrition in laying hens.

Laying hens can cause fatty liver disease if they are over-nutrition, also known as fat syndrome. This condition often occurs in caged flocks. Due to long-term feeding of high-energy feeds containing protein and carbohydrates, and lack of methionine and choline in the feed, the performance of fat metabolism is reduced. Insufficient exercise, neutral fat is precipitated in the liver, so overnutrition leads to the development of fatty liver disease.

For this kind of fatty liver disease caused by overnutrition in the laying hens, the farmers should take prevention as the main factor. In the usual feeding, in order to increase the green and succulent feed, improve the diet formula, reduce the supply standard of high-energy feed containing protein and carbohydrates, balance the nutrition and prevent excess.
