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.
What are the main points of the laying period?
Do you know how many days of hatching an egg can produce a chicken? When does the chicken grow to start laying eggs? What is the peak period of laying eggs? do we need to care something?
A fertilized egg usually hatches the chicken after 21 days, the duck egg is 28 days, the goose egg is 30~33 days, the pigeon egg is 18 days, the pearl egg is 26 days, and the fire egg is 27~28 days. It takes these stages for a chick to go from hatching to final elimination.
Chicken raising, especially laying hens, determines the length of the egg production period. Why should limit light and limit materials before? Because, at the stage of 43~126 days, if the light is not limited, the chicken will lay eggs in advance, resulting in a shortened egg production period of 3 to 5 months, causing serious losses.
So the peak of egg production is so important, what should farmers pay attention to?
In addition to daily management, pay more attention to the condition of laying hens. Usually, in addition to packing eggs in egg packing system, clear dung, feeding, cleaning, you should also observe the status of the laying hens, see if there are sick chickens, etc. In short, pay more attention. Laying hens must ensure that nutrition is kept up.
Reduce stress and maintain environmental sanitation. High-yielding laying hens are easily frightened, resulting in less food for laying hens and lower egg production rates.
The problem to be paid attention to in raising chickens in summer: the optimum temperature for chicken adaptation is 13 to 25 degrees, and the production is customarily used for 21 to 25 degrees. In the hot summer, the chickens are fed in the cool morning.
Temperature control management of spring broiler breeding
The temperature difference between day and night in spring is large. It is necessary to pay attention to controlling the constant temperature. If the temperature is too high or too low, the weight of the broiler will be affected. The weight of the chicks should be 4 times of 7 days after entering the house. If this standard is not met, it will affect the growth and development of broilers. If the temperature exceeds 38 ° C for more than 3 hours in the first week of brooding, it will affect the growth and development of the chicks.
(1) Temperature control before chicks enter the poultry farming cages.
Be sure to fully pre-warm the brooding room, preferably more than 12 hours in advance, to keep the temperature of the air, floor and wall of the house consistent. In production practice, the temperature of brooding is not up to standard. Although the temperature in the air has reached the required level, the ground temperature is still relatively low. It is easy to appear cold on the second day after entering the chick. Although it can be adjusted, the late chicks tend to The intestinal tract is not good.
(2) Pay attention to temperature control during immunization.
Every immunization should control the temperature, preferably 2 ° C ~ 3 ° C higher than usual, due to the weak immunity of the body during immunization, it is easy to infect mycoplasma or E. coli disease, so during this period the house should be suitable temperature.
How to manage the battery hen cages before laying eggs?
Now that science and technology are advanced, people's breeding is becoming more and more standardized, and more and more chickens are raised using poultry chicken raising equipment. So how should we manage the use of battery hen cages before laying eggs?
First of all, we must feed scientifically, do not increase or decrease the feed at will. The main reason for the change of feed for laying hens is that the production chickens need calcium supplementation.
If calcium is supplemented too early, the growing chicken will not have the absorption function. If calcium supplementation is too late, it may cause poor egg shell quality. Some farmers are always blindly confident and increase or decrease feed at will. This may cause the egg production to not become a scientific curve and affect the income of farmers. Therefore, farmers must insist on scientific feed feeding.
Secondly, scientifically increase the light time. After entering the laying period, the light time should be extended in the chicken house, and the light time should be gradually increased according to the weight of the laying hens from 18 weeks to 20 weeks of age. After the longest exposure time is 15-16 hours, it remains unchanged. Some farmers always want to advance the egg laying time and increase the light time at will, which may affect the laying cycle, and the gains outweigh the losses. Therefore, farmers must follow the scientific rules and gradually increase the light time.
Finally, maintaining a quiet environment in the chicken house is crucial. As we all know, the harsh noise of chickens, especially the laying hens, must keep the chicken house quiet to avoid excessive reactions. After laying the first two eggs, the laying hens are extremely excited, and even behave a little nervously or move abnormally. At this time, it is necessary to keep the chicken house as quiet as possible to avoid disturbing the laying cycle.
The above is the summary of how the layer cages should be managed before the laying hens lay eggs. Hope that the farmers can manage the chicken coop well.
How to solve the problem of broken eggs
Egg breakage has become a headache for many laying hen farms. Nowadays, farming equipment and chicken battery cages are use to raise chickens and collect eggs. According to statistics, the breakage rate of eggs in many laying chicken farms is above 2%. Especially in the early stage of the chicken and egg production, the performance is relatively serious, generally between 1-3%, and some chicken farms have a higher damage rate, even more than 6% in poultry farming cage equipment
Once the egg is damaged, its economic value will drop by more than 60%, severely lose its economic value, and it will pollute normal eggs due to the outflow of egg liquid, and even cause pathogen reproduction pollution. The economic loss caused by broken eggs can account for more than 0.5% of the farming income. According to statistics from relevant departments, the direct economic loss caused by eggshell damage to the laying hens industry is as high as 500 million yuan per year, which has become one of the main factors affecting the efficiency of laying hens.
Especially with the change of breeding mode, the feeding cycle is prolonged, the application of mechanical egg collection is promoted, and the eggshell quality problem has attracted much attention. One of the most important reasons why eggs are damaged is that they lack vitamin D3, specifically 25-hydroxyvitamin D3. Some people think that it is calcium and phosphorus deficiency, and the test proves that there is no calcium deficiency in the feed. The broken egg indicates that the chicken has problems, that is, it is not healthy enough. At this time, supplementing “25-hydroxycapsule” to improve the health of the chicken and strengthening the eggshell is a smart choice.
When the calcium and phosphorus in the feed are not balanced, supplementation with 25-hydroxyvitamin D3 can increase the absorption of calcium and phosphorus. In the hot summer, the phytase added to the feed is prone to failure due to high temperature, resulting in insufficient phosphorus and imbalance of calcium and phosphorus. In the case of calcium and phosphorus imbalance, the addition of 25-hydroxyvitamin D3 is more significant. High temperature in summer can easily cause heat stress in chickens. Heat stress can affect the quality of eggshells (the eggshells become thinner and brittle). The reason is that the blood calcium reduction of laying hens is also lower than the reduction of carbonic anhydrase and vitamin D activity in laying hens. The important reason. Supplementing 25-hydroxyvitamin D3 can increase the egg production rate, reduce the egg breaking rate, reduce the egg-to-egg ratio, especially increase the eggshell hardness and reduce the egg breaking rate.
How to maintain automated poultry farming equipment
Automatic poultry farming equipment plays a very important role in the modern breeding industry. They are also widely used by farmers. It is very necessary to do a good job of maintenance during the use of breeding equipment, so that they can work better. Effective maintenance and maintenance can extend the use time of the equipment, so how should we pay attention to maintenance during use?
The content of maintenance and maintenance of automated chicken breeding equipment generally includes daily maintenance, regular maintenance, regular inspection and precision inspection. In addition, for some exciting equipment, equipment lubrication and cooling system maintenance is also an important part of maintenance. Generally speaking, daily maintenance is the basis of equipment maintenance work. Therefore, farmers need to be standardized and institutionalized to maintain and manage.
Periodic inspection is a planned, targeted and preventive inspection. In addition to the human senses, the inspection means must also have certain inspection tools and instruments. Farmers should observe and inspect the operation of chicken battery cages, automatic feeding systems, automatic drinking water systems, automatic ventilation systems, and automatic manure removal systems on a regular basis.
The maintenance of breeding equipment needs to be carried out on a regular basis, so that the operating conditions of the equipment can be grasped in real time, and problems and failures can be discovered in time and solved immediately. We usually maintain effective maintenance at any time during use, so as to effectively extend the service life of the equipment and save time and effort.
Pay attention to the feed configuration of chickens in layer cages
Battery chicken cages to raise chickens live in cages, and the source of nutrition is feed. In order to ensure that the laying hens get balanced nutrition, farmers can choose and feed according to a series of nutrients to achieve balanced nutrition in the laying hens and ensure the laying hens Good egg production performance.
- The content of salt should not be too high: Salt is a raw material and must be added in the process of preparing feed. It can increase appetite and prevent feathers and anus pecking. However, if the farmers add too much salt to the chicken feed, it will cause the laying hens to be thirsty and then need a lot of water, which will lead to excessive drinking water and frequent intense diarrhea. In addition, farmers should pay attention to the rich salt in fish meal, so farmers must control the amount of salt when adding, so as to avoid excessive salt in the feed, causing diarrhea in laying hens.
- The amount of stone powder should not be too high: stone powder is also a raw material that farmers often add when preparing feed, but it should be noted that if the amount of stone powder in the diet is too high or increase too fast, it will cause excessive blood calcium in laying hens and increase The kidneys are burdened, causing the kidneys to swell. This will eventually lead to diarrhea. When preparing the feed, the editor reminds farmers that the amount of stone powder should be gradually increased with the increase in laying rate of laying hens, and should not be added too much at once.
- Prevent mildew of raw materials: High temperature and high humidity can easily lead to mildew of feed, so moldy feed farmers should not feed them to laying hens, because moldy feed contains some toxins, which can stimulate and destroy the intestinal mucosa of laying hens. , Which in turn leads to increased intestinal mucosal permeability of laying hens, leading to diarrhea in laying hens.
Automatic poultry chicken equipment manufacturers here remind farmers to pay attention to the nutritional balance of the feed to ensure that the chickens receive adequate nutrition and grow healthier.
What to do with soft shell eggs
For laying hens, egg production rate and egg quality are very important, and it is also directly related to the economic benefits of laying hens. If too much soft shell egg will affect the income, how should it be improved?
In fact, the main reason for the appearance of soft shell eggs is that the intake of calcium in the laying hens is insufficient. The lack of calcium leads to the thinning of the eggshells, so there will be soft shell eggs or even shelless eggs, so it must be in daily breeding. Pay attention to the calcium supplementation of laying hens. The calcium required for eggshell formation is mostly derived from feed, so feed is an important factor.
For calcium supplementation in laying hens in poultry farming equipment for sale, it is necessary to choose a suitable calcium material. Usually, when calcium is added to the laying hen, two or more kinds of calcium materials can be selected for calcium supplementation,which is better.
The best time for calcium supplementation is mainly 2-4 pm, which is most suitable because only the calcium absorbed in the afternoon or evening will participate in the formation of the eggshell at night, and the afternoon is the peak of the feeding of the hens in the afternoon. At this time, the appetite is high and the food is eaten, so the effect of calcium supplementation at this time is the best.
The higher the calcium content of the feed, the better, otherwise it will be unfavorable for laying eggs. Timely calcium supplementation for laying hens will have a good benefit. If the calcium content is insufficient, it will lead to an increase in the production of soft shell eggs and a certain loss.

Breeding equipment manufacturers share prevention and control measures for laying hens
There are more and more farmers raising hens, and they are all using battery cage for chickens and breeding equipment to raise chickens. How should the hens prevent the stress reaction in the chicken cage and Poultry Rearing Equipment? Here are some suggestions.
1. Farmers should start from the growth characteristics of laying hens to provide a good, quiet and comfortable growing environment for the laying hens. The control of temperature and humidity, as well as the management of ventilation should be scientific and reasonable, avoiding the sheds caused by poor ventilation. Moisture and air pollution, etc., to avoid the stress of environmental failure.
2. Farmers must ensure that the stability of feeding during the whole breeding process, such as laying water, feeding, disinfection and other environments, must be in order, time is regular, farmers should pay attention to not being able to break water, lack of materials .
3. During the breeding process, the farmers should control the environment of the chicken house, such as fixing the time of the switch lights, cooling the work in the summer, keeping warm in the winter, and preventing the adverse effects of high and low temperature on the laying hens. In the autumn when the temperature changes greatly, timely prevention and control measures should be taken. In the rainy season, work to prevent storms is also needed.
4. In the farm where the laying hens are raised, the farmers should be careful not to yell and scream, and pay attention to the chicken houses not to be built in noisy places.
5. The feed ingredients required for different growth stages of laying hens are different. Therefore, the farmers must change the feed at a fixed stage, and there must be a transitional stage in the process of replacing the feed, so as to ensure the smooth adaptation of the chicken.
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.
