How to fully master the skills of controlling high temperature and high humidity in chicken houses?
Higher temperatures in summer can lead to reduced appetite and reduced feed intake. As a result, the metabolic capacity of the chicken in layer battery cage, the nutrient intake of protein, vitamins and minerals is seriously insufficient, resulting in a decline in production performance. Therefore, dietary formula must be adjusted to meet heat stress. To meet the nutritional needs of chickens.
The caloric content of various nutrients varies greatly during digestion. Protein produces the most heat, and fat produces the least amount of heat. In order to reduce the heat dissipation burden of the chicken, the crude protein level should be reduced as much as possible to ensure the essential amino acid content and amino acid balance. Avoid excessive protein and increase the proportion of fat feed by adding fat. Heat stress in laying hens leads to reduced feed intake, resulting in insufficient energy intake.
Adjust the paper feed mode and lighting time. In the summer, the temperature is higher at noon, the appetite of chicken is low, and the temperature is suitable in the morning and evening. Chicken has a strong sense of hunger. At this point, the feed stimulates appetite, increases feed intake, and has a lower peak heat production. Time, because the maximum heat production related to digestion is 3-5 hours after feeding, should be avoided after 9 am to meet the nutritional needs of chicken production or growth, improve its anti-stress ability, broilers can rest the lighting system at night , low light illumination for 1 hour, light off for 2-3 hours, and so on. Egg laying hens can turn on the lights around 1 am, let the chickens heat up, drink water and feed, and the chickens start laying eggs when they are bright, so as to avoid laying eggs at high temperatures at noon. And reduce heat stress. It is estimated that 80-90% of consumption is consumed when it is cool. For free-fed broilers, two feeds can be supplied at the same time, one material is normal, the other material has a low nutrient concentration, and the chicken can be selectively eaten as needed. Tests have shown that this method can improve weight gain and feed compensation. Reduce the cost of feeding and mortality of poultry farming equipment for sale.
During heat stress, 80% of body heat is dissipated by evaporation. Try to stimulate the chicken to drink plenty of water to ensure that the drinking water is adequate and cool. Since low temperature water can carry away more heat in the body, it can relieve heat stress and reduce heat stress. The adverse effects of heat stress on feed intake. However, drinking water must be hygienic, preferably deep well water. When the house is exposed to high temperature and high humidity (temperature exceeds 35 ° C, humidity exceeds 70%), the following measures should be taken to prevent acute death. Close the wet curtain and turn on all fans to remove moisture from the house. When the humidity exceeds 80%, the side windows and doors in the front half of the house should be opened immediately, so that the air inlet area is larger than twice the area of the air outlet to achieve rapid dehumidification for poultry farm equipment suppliers.
Environmental management of chicken farms
1. The chicken battery cages are not connected to each other to avoid cross-infection between the chickens and the chickens.
2. The farther away from other chicken-raising units, the better, thus reducing the risk of disease transmission;
3. All the houses must be thoroughly cleaned with high-pressure faucets. All tools in the house, such as electric fans, brooms, etc., must be cleaned;
4. Ensure that chicken farm personnel are not in contact with the outside flocks;
5. All chicken houses must be disinfected with a broad-spectrum cleaning agent that kills important pathogens;
6. Actively take measures to control rats, flies and stray animals. Once a mouse is present, use rodenticide or use a rodent-proof house to clear and control it;
7. When chickens of different ages are raised in the same chicken farm, the care of the chicken must start with the healthiest chicken feathers (usually the smallest chicken). Workers are not allowed to return to the chicken house from the big chicken house until the clothes and boots have been properly cleaned and disinfected;
8. If the dead chicken is found, the chicken house should be taken out immediately and disposed of immediately;
9. Workers must always wear clean clothes and boots when entering the house. Those who have been in contact with the big chicken-type laying hen must take a bath before entering the chicken house to save the person;
10. Non-essential personnel are not allowed to enter the chicken farm. Visitors must abide by the above rules;
11. Vehicles outside are not allowed to enter unless they are cleaned and disinfected.
How much do you know about layer cage equipment?
Layer cage equipment is an integral part of modern laying hen farms. Sometimes they are called chicken coops. But now "A" and "H" layer battery cages price are the newest laying hen cages for poultry farms! Stacked layer cages are mainly used in poultry farms.

Humidity conditions for laying chickens in laying hen cages
When using layer chicken cages to raise chickens, humidity is also an important condition for brooding, but chicken farmers generally do not pay enough attention. The humidity in the brooding house is generally expressed in relative humidity. The higher the relative humidity, the more humid the air; the lower the relative humidity, the drier the air.
After the chicks come out of the shell, they enter the brooder house. If the humidity of the air is too low, the moisture in the chicks will be exhaled through breathing, which is not conducive to the absorption of the remaining yolk in the chicks and the growth of the chicks' feathers. Once the chicks have been given a drink, the chicks often develop diarrhea due to too much water.
Appropriate humidity requirement: 60%-65% before 10 days of age, and then reduced to 55%-60%. In the early stage of brooding, due to the dry litter, the house is often hot and low humidity, which is easy to increase the water loss of the chicks, loss of appetite, frequent drinking, dry and brittle fluff, and dry toes.
In addition, too dry can easily lead to dust, causing respiratory and digestive diseases. Therefore, this stage must pay attention to the replenishment of water in the house. You can spray water on the aisle or wall of the house to increase humidity, or place a basin or kettle on the stove to burn water to generate steam to increase the humidity in the house.
After 10 days of age, the chicks developed quickly, gained weight, and their feed intake, water intake, breathing volume, and excretion volume increased with each passing day, and the temperature in the house gradually decreased. Especially in the midsummer and rainy seasons, it is easy to have excessive humidity. The chicks are not well adapted to the humid environment. The low temperature and high humidity in the brooding house will exacerbate the adverse effects on the chicks at low temperatures. The chicks will feel colder and even tremble with cold, at this time susceptible to various respiratory diseases. When the high temperature and high humidity in the brooding house, the water evaporation and heat dissipation of the chicks are hindered, and they feel more sultry and uncomfortable, and the chicks are prone to coccidiosis and aspergillosis.
Therefore, during the period when laying hens cages are used to raise chickens, it is necessary to change the litter frequently and strengthen ventilation. When adding drinking water, prevent water from spilling onto the ground or litter.
About the layer battery cage feeding mode
Under the development of breeding automation, the layer battery cage breeding mode has been widely recognized by the majority of layer farms. This breeding method has a small area and high space utilization. The layered cleaning of chicken manure can not only improve the utilization rate of chicken manure, but also It also reduces the degree of environmental pollution. At the same time, labor intensity is reduced and productivity is improved. Although stacked cages have many advantages, the premise is to know how to use them and how to manage them.
Due to the inconvenience of layer battery cages, it is inconvenient to catch the chickens. The laying time for laying hens can be appropriately extended. Vaccines that require immunity, such as Newcastle disease, infectious bronchitis, avian influenza, and egg drop syndrome, should be completely immunized before being basketed. over. When the egg production rate reaches 5%, the prenatal feed should be replaced with peak feed. The refueling will take one week for the transition. At this time, the feed should maintain high quality and stable nutritional content, and do not change the finished feed and raw materials at will.
In addition to the conventional power system, a generator that matches the chicken farm must be required and can be automatically switched. To ensure uniform light in the house, light bulbs can be installed on a staggered level or row of lights can be used. In order to ensure the service life of the equipment, lubricate the transmission parts such as the transmission sprocket and gears of the transmission box once a month when in use. Clean the surface of the egg roller and fecal roller in time. Clean up the impurities in the soft and broken egg collection tray in time. The ventilation system should be adjusted appropriately for side wall ventilation and roof ventilation according to the different seasons. Always keep the lighting bulb clean to prevent affecting the light intensity.
Feeding nutritional requirements when using broiler cages to raise chickens
Many broiler farm cage manufacturers believe that the main task in the rearing period is to cultivate healthy, well-balanced chickens with a body weight that conforms to the normal growth curve to ensure timely production. Therefore, in production, we must pay full attention to the dietary coordination of growing chickens. The content of crude protein in the diet should be appropriately reduced, which can be gradually reduced from 18% to 19% during the brooding period to 16% to 15%.
At the same time, reduce the energy concentration in the diet. When compounding diets, low-energy feeds such as rice bran and wheat bran can be used to replace part of high-energy feeds such as corn to help exercise the stomach and intestines, improve the digestion of the feed, and make the growing chickens have a good body condition. Pay attention to supplementing vitamins and minerals. The content of calcium, phosphorus, selenium, zinc, etc. and the ratio of calcium to phosphorus in the diet should be appropriate.
During the rearing period, the feed should be changed at least twice at the age of 6-7 weeks and at the age of 16-18 weeks. There must be a transitional period for each refueling. It is not possible to change all suddenly, so that the chicken has a process of adaptation. Especially from the brooding period to the rearing period, the replacement of feed is a great turning point. The nutrient content of feed, such as crude protein content, has dropped from 18% to 19% to 15% to 16%. Changes in feed ingredients can easily change the palatability of chickens and reduce feed intake. If they are not managed well, chickens are prone to disease.
Therefore, the following methods can be adopted for feed transition. From the first 1 to 2 days of the 7th week of age, 2/3 of the breeding period feed and 1/3 of the breeding period feed are mixed and fed. For 5-7 days, use 1/3 of the brooding period feed and 2/3 of the rearing period feed to be mixed and fed. From the 8th week of age, they are completely fed with feed during the growing period.
The first kind of feed change method is relatively detailed, and it is often used when the composition of the chicks and feed species changes greatly. The third refueling method is relatively crude, and experienced farmers and broiler cage manufacturers believe that it is generally used when the composition of adult chickens and feed species changes little. The second refueling method lies between the two and has a wide range of applications.
The above are the precautions when using broiler cages to raise chickens. I hope that the above content will be useful for novice farmers.
Harmfulness of Ventilation in Poultry Houses
Because broilers grow fast, metabolism is high, and they are high-density breeding, as the chickens continue to grow, more and more fresh air is needed, and more feces are discharged, and the more harmful gases are produced. The more gases that are most harmful to chickens, the ammonia and hydrogen sulfide for battery cage system in poultry.
Ammonia is a colorless gas with a strong pungent odor. It has a small specific gravity and generally rises to the top in a warm house. However, since ammonia is produced on the ground and around the chicken, the content of the ground in the chicken house is also high, especially When the house is wet and poorly ventilated, the concentration of ammonia in the house is higher. Chicken is particularly sensitive to ammonia. Ammonia has a stimulating effect on the mucous membrane of chickens, which can cause mucosal congestion and edema of the conjunctiva and upper respiratory tract. Pathogens fly through the upper respiratory tract and lung infections to the chest and abdominal airbags, causing respiratory disease in chickens, and the feed intake is reduced, which not only affects the growth and development of chickens, but also reduces the resistance of chickens to diseases, chickens and diseases. The incidence of chicken venomosis is increased and the production performance is greatly reduced in battery cage for layers.
Details to be concerned during the breeding process
When using poultry farm cage to raise chickens in the farm, pay attention to many details. The water supply must be normal in the whole process of chicken feeding, no water leakage, no blockage, no pollution. This requires thorough cleaning of the water line before cleaning the chicken, wiping the cup, checking the nipple installation and water leakage. A simple leak phenomenon is not the result of management slack. This shows that we have fewer visits to and from the house, and the work in the house is not fine enough. If the water leaks too much on the ground, it will cause a chain reaction, which will increase the humidity in the house. Under high temperature, the chicken manure is mixed with the feed and fermented rapidly to produce a thick ammonia gas. Excessive concentration of ammonia will damage the respiratory mucosa of the chick, the respiratory tract. The mucous membrane is the first barrier against the invasion of foreign evils. Once damaged, the chicks are completely filled with pathogens, and the immune system is overwhelmed by a variety of pathogens. The end result is a mixed infection in poultry cage equipment.
The fully automatic material line saves labor and improves work efficiency, which does not mean that you no longer pay attention to the feeding problem. In the process of breeding, there must be no leakage, no material, no mold. For example, there is only one reason for the missing material problem, that is, the tray is not installed. If the breeder's work is done with enough care, check the number of times before loading, and fix the position probe after each expansion. The above problems will be solved. If the most basic water and materials in the house are insufficient, it can be imagined that other equipment in the house can operate smoothly.
Temperature, humidity and ventilation. Those who are engaged in farming know that temperature, humidity and ventilation are closely related and contradictory. Especially in the winter and spring seasons, the temperature is low, the humidity is relatively small, and at the same time, enough fresh air is supplied to the house. If the ventilation is too large, the temperature and humidity will decrease greatly; if the ventilation is too small, the air quality in the house will be poor. In summer, the temperature and humidity are too high, and it is often necessary to increase ventilation to reduce the humidity in the house and the somatosensory temperature of the chicken. As far as the current season is concerned, although it is a beautiful season for spring blossoms, the temperature difference between day and night is large, and there are many windy weathers. So how to adjust the fan and small window, adjust the temperature inside the house evenly, and the humidity and sufficient oxygen in the house. It has become a key task.
When the temperature is high during the day, ventilation can be increased, and the ventilation time is twice or even greater at night. Sufficient fresh air is clearly beneficial to alleviate the symptoms of respiratory diseases. In the evening, everyone eats and rests. When everyone is most relaxed, the temperature begins to decrease. At this time, the small window should be adjusted in time to prevent the cold air from being fully warmed up on the chicken. This way the chicken will only feel more comfortable and there is no feeling of quenching. In the windy weather, whether the small windows of the north and south walls have been adjusted accordingly to avoid inconsistent air intake in the north and south walls. Try your best to minimize stress, and the chicken will naturally not catch a cold. Stress is the source, and viruses such as colds are fueling the waves. When you have not responded in time, they will push the flocks to the abyss step by step.

Methods for raising chickens in layer cages to prevent egg breakage
Farmers are in the daily process of raising chickens. There are some broken eggs caused by careless management. Eggs are affected by the health of the chicken, and the hardness of the eggshell will also vary due to the health and quality of the chicken flock. Here are some methods for farmers to prevent egg breakage.
After laying hens begin to lay eggs, they increase with age. The surface of the egg will also increase. The strength of the eggshell is reduced. Therefore, the older the laying age, the higher the breakage rate. In laying hen cages, the higher the egg breakage rate of standing or squatting laying hens is lower. Laying hens lying prone or squatting have lower egg breakage rates.
Laying hens lack the light required to absorb calcium at night, and the eggshells formed are thinner. Therefore, the breakage rate of eggs laid in the afternoon is lower than that of eggs laid in the morning. The health of the chicken also affects the quality of the eggs. Many diseases have an impact on the quality of eggshells. Such as infectious bronchitis, etc. will make the egg structure abnormal, irregular shape, and increase the egg breakage rate.
Among the nutrition, calcium, phosphorus and vitamin D have a greater impact on the quality of eggshells. Under normal circumstances, the amount of calcium required in the diet of laying hens should be 2.7-3.75%. This is 3-4 times larger than the 0.9% calcium requirement of non-laying hens. The phosphorus requirement of the laying hen's diet should be 0.5%. Vitamin D can promote the absorption of calcium and phosphorus. Such as in the absence of vitamin D. Even if the laying hens are fed rich calcium and phosphorus, they will produce soft-shelled eggs.
Environmental changes and the temperature of the chicken house have a greater impact on the eggshell. The higher the shelf temperature, the more broken the eggs. In summer, the eggshells of eggs laid by chickens are usually about 5% thinner than eggs in other seasons. This is mainly because high temperature will reduce the feed intake of chickens, and the intake of calcium will be reduced accordingly. In addition, in a high-temperature environment, if the relative humidity is high, the heat dissipation of the chicken is not good, and the egg will be damaged even more.
Farmers can purchase automated chicken raising equipment. It contains an automatic egg collection system. The chicken coop has a slightly inclined angle. After the laying hen lays the egg. The eggs roll along the conveyor belt. This reduces the egg breakage rate.
How to determine the proper temperature of the house
In the process of raising chickens, the temperature of the chicken battery cages is one of the important factors that can affect the health of the entire flock. Regardless of the type of chicken, the demand for temperature is very high, and a slight inadvertent disease can occur. The temperature required for different breeding stages of the flock is also different. Chicken farmers are required to breed according to this standard, and the flock can grow better and produce higher benefits. And the majority of chicken farmers can set the temperature from the performance of the flock, what is it?
1, group performance
The proper temperature is that the chickens are evacuated and even, the body is stretched, and some chickens breathe as evidence. If they are piled away from the heat source, the respiratory rate will increase, especially if the chest breathing is increased, and the temperature is too high; if it is near When the heat source is piled up and the respiratory rate is lowered, the temperature is too low. However, the premise of this testimony is that the humidity is appropriate and the flock is healthy. If these two premises are lacking, they cannot be fully referenced.
2, individual performance
If we enter the chicken cages for sale, we find that many chickens are stretched, and the neck hair is reversed, the head is tied down or the neck is lowered, and the pneumonia is caused by low humidity and high temperature. If the hand is under the wing and the abdomen is hot, then the relatively low temperature needs to be supplied. Conversely, if the hand feels cold and the legs are blue, it is necessary to provide a higher temperature.
When the temperature of the house is within the set temperature range, according to the temperature table of the chicken, normal ventilation should be carried out in the house to ensure that the air in the house is fresh. The proper temperature in the house can make the body better. Stretching, if you find that the flock is breathing too fast or too slow, there is a problem with raising the house. In addition, if the flock is low or the neck is stretched, the chicken farmers should pay attention. The temperature that is too high or too low will cause discomfort in the flock and pneumonia. In addition, the chickens can be removed and the cause of the disease can be found. The majority of the chicken farmers can judge according to the actual situation of their own breeding.
