Key points of light control technology for laying hens
Light is one of the necessary environmental conditions for laying hens. The intensity, time and color of light are very important for chicken activities, metabolism, growth and productivity, especially for laying hens raised in layer battery cage equipment. Reasonable control of light can improve the production capacity of laying hens and the economic benefits of farmers.
1. The effect of light on laying hens
Light stimulates the hypothalamus directly through the skull or light through the nerve pathway of the nerve lobe. After the hypothalamus is stimulated, it secretes gonadotropin-releasing hormone, which reaches the anterior pituitary through the pituitary portal system, causing follicles The secretion of stimulating hormones and ovulation hormones promote the development of follicles and then ovulation. The developing follicles produce estrogen, which promotes the development and function of the hen’s fallopian tubes. At the same time, estrogen also promotes calcium metabolism to facilitate the formation of eggshells. Ovulation hormones Causes hens to ovulate. In a closed chicken house, no matter how nature changes day and night. The laying of eggs by hens is mostly concentrated in the first 2-7 hours of artificial light.
2. Control of lighting technology
1. Lighting time. The length of lighting time is closely related to the age of sexual maturity of chickens. Too short light time during the rearing period will delay sexual maturity, and too long time will lead to early sexual maturity.
2. Light intensity. Appropriate light intensity is conducive to the normal growth and development of chickens. Excessive light can make chickens irritable and cause severe pecking, prolapse or nervousness. The sudden increase in light intensity during the laying period can significantly increase the rate of cracked eggs, soft-skinned eggs, deformed eggs, and sudden death; low illumination can accelerate the deposition of body fat, but the illumination is too low. It will reduce the chicken's feed intake, reduce drinking water, hinder growth and development, and reduce egg production.
There are four ways to control the light intensity: one is to control the intensity by increasing or decreasing the number of bulbs; the other is to adjust the intensity by changing the bulbs of different power; the third is to control the intensity by adjusting the voltage; the fourth is to control the intensity by adjusting the spacing. But no matter how you adjust, each time you turn on and turn off the lights, you must gradually change from dark to bright, from bright to dark, to give the chickens an adaptation process to prevent frightening the flock. The distance between the bulbs should be 1.5 times the height of the bulb from the ground; the distance between the lamp and the wall should be half the distance between the bulbs, and the lamps between rows should be arranged in a staggered manner to obtain a more uniform lighting effect.
3. Light color. Laying hens are more sensitive to color. Chickens have better vision under red, orange and yellow light. Under red light, it tends to be quiet, with very few pecking habit, a little later in maturity, high feed reward, and egg production slightly increased; yellow light reduces feed reward, delayed sexual maturity, increased egg weight, decreased egg production, and increased pecking ; Green light can make sexual maturity earlier and weight gain faster; blue light can reduce hen egg production.
Treatment measures for laying hens and anus
Use a comprehensive and high-quality feed in your chicken cage for sale; 2 add methionine, vitamins and trace elements to the feed; 3 spray the body surface and environment with a 2.5% dilution of 2.5% bromide, use it for 2 days, or use internal and external. The anthelmintic drugs are mixed for 250 to 500 kilograms per bag for 3 to 5 days.
The chickens that are used to the individual habits of the feathers are only resolutely eliminated.
In order to prevent the occurrence of tubal inflammation, high levels of amoxicillin and doxycycline are added to the drinking water for 3 to 5 days. Add high quality quick fix in drinking water. Increase the amount of vitamin C used in the feed. Poultry farmers shouldn't ignore the importance of environmental control system.
The main points of the environmental temperature control of the battery layer hen cages
The right temperature of the chicken house can exert greater production potential for chickens. The quality of environmental control directly affects the success of breeding. Therefore, temperature control is an important factor in feeding. The following chicken breeding equipment manufacturers explain the main points of chicken house temperature control.
In the environmental control of the layer hen chicken house, the layer chicken can obtain a higher survival rate, weight gain speed and feed remuneration in the above-mentioned suitable temperature environment. Whether the specific temperature of each brooding is appropriate or not is determined by the dynamic performance of the chicks:
When the temperature is appropriate, the chicks are evenly distributed indoors, lively, with smooth feathers, and close to the body surface. They are relatively quiet during sleep and scramble to eat.
When the temperature is too low, the chicks will show low temperature performance. The chicks will be crowded near the heat source or in a certain corner, their feathers will be fluffy, the spirit will be wilted, and they will make continuous calls. This way for a long time, it is easy to cause the chicks to catch a cold or be crushed to death. It must be heated immediately and the crowded chicks must be dispersed.
When the temperature is too high, the chicks stay away from the heat source, spread their wings and lie down, panting, and rush to drink water. There is often no water in the drinking fountain, but the fluff is wet. Over time, the physique of the chicks will be weakened, growth will be hindered, and even heat death will be caused. When the temperature is too high, the temperature should be gradually lowered, but be aware that a sudden drop in temperature can cause a cold.
Therefore, attention must be paid to the temperature control of the chicken house during the entire feeding period of the laying hens. A thermometer can be placed in an appropriate place in the house for observation, and certain measures can be taken to cool down or adjust the temperature. In the hot season, when the temperature in the chicken house is high, you can open the doors, windows and vents, turn on the fan or exhaust fan, increase the ventilation in the house, and lower the temperature in the house. When necessary, cold water can be sprayed on the ground or sprayed on the roof to cool down.
The use of poultry battery layer hen cages to raise chickens requires more attention to the living environment of the chickens in the hen house. Provide a suitable temperature environment for the chickens so that they can grow healthier.
Why Chicken immune failure
When we raise chickens in poultry farming equipment, it is common to vaccinate chickens to prevent disease, but sometimes it is still vaccinated. Why is this?
The first is that immunization is unscientific. The time of inoculation is not appropriate. Therefore, there is an inaccurate possibility of immune effect.
The second is that no antibody detection is performed. If the flock is in a special period, it is prone to immune failure without antibody testing.
The third is that the dose used for the vaccine is not accurate. It is not good for chickens to use large doses of vaccines.and is to cause adverse reactions after inoculation.
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.
Factors that need to be learned in layer cage breeding
As the breeding industry using layer chicken cages in Ghana continues to expand, the scientific nature of breeding technology is becoming more and more important. The selection of chicken coop equipment, reasonable design of chicken coops, the control of chemical dosage, air circulation, and disease prevention are becoming more and more professional and scientific, which requires a group of high-tech breeders. So what aspects should be paid attention to in laying hen breeding?
1. suitable environment
Proper temperature, proper humidity, proper ventilation, proper stocking density, proper light
2. Sufficient drinking water
Ensure that the laying hens have proper drinking water, effectively ensuring the healthy growth of the laying hens.
3. Standard weight
Overweight or underweight will affect the laying rate of laying hens.
4. Reduce all kinds of stress
Suitable environmental factors are one of the key factors affecting the growth of laying hens.
5. Strengthen disinfection
Strengthen disinfection in the house and cleaning outside the house to ensure the cleanliness of the breeding environment and reduce the occurrence of diseases.
6. Immunization vaccine
Use vaccines correctly and reasonably to effectively control and reduce the derivation of poultry diseases.
Four key points for raising chicken to supplement light
In the process of raising chickens in laying hens, the farmers know that the hens need reasonable illumination, and the natural light often does not achieve good results. Therefore, when the chickens are illuminated, they need to use artificial lighting equipment for artificial replenishment. Reasonable illumination is beneficial to the growth and production performance of laying hens, so it is a very important task. The author reminds farmers to pay attention to the following four points in addition to the time to light and the number of lighting equipment:
1. The chicken farming equipment illumination should be stable: the time for the average farmer to choose to supplement the light for the laying hens starts from the age of 19 weeks. When the light setting time is set, the light should be slowly increased from short to long, increasing by half an hour every week. It is appropriate. Farmers should pay attention to the fact that when the light is increased to 16 hours a day, it should be kept in stable light, and then the daily light can not be long and short. The best way is to add light every morning and evening.
2. The intensity should be suitable: the farmers should pay attention to the light intensity of the lighting equipment. For normal laying hens, the required light intensity is generally 2.7 watts, but the multi-layer culture mode of the egg cage culture, so the bottom layer The flocks are not easy to feel the light, so it should be improved when setting the light intensity, generally 3.3 to 3.5 watts per square meter.
3. The illuminance should be uniform: the farmers should pay attention when installing the lighting equipment. We suggested that the bulbs installed in the chicken houses of the farmers should be 40 to 60 watts, and then the height of the lamps should be set at about 2 meters. The distance between the bulbs is recommended to be about 3 meters. In addition, the farmer should pay attention to the fact that if your house needs to install more than two rows of bulbs, you should cross them so that the light is even, the distance between the wall and the wall. Should be half of the bulb spacing, should also pay attention to replace the broken bulb at any time, wipe the bulb once a week to maintain the proper brightness in the house.
4. It is advisable to use red light: there are many kinds of light colors in the lighting equipment. Farmers should pay attention to the different light colors of the lighting equipment when they choose, and the wavelengths are different. Tests have shown that hens under red light have higher egg production rates than hens under other light conditions when other conditions are the same, so it is recommended that farmers choose red light equipment.
Spring management of the chicken house environment
The use of chicken cages to raise chickens is a popular chicken raising method in the chicken industry. The chicken cages are raised in a multi-layer cage. The breeding density is large and the number is large. It is very popular among farmers, using chicken cages to raise chickens, and which are Need to pay attention to the chickens to pay attention to the matter, only pay attention to all aspects of feeding points, scientific and reasonable breeding can be able to raise the higher yield of the chickens, the following authors to tell the majority of farmers to use the chicken battery cages in spring Chicken's precautions.
1. Humidity
Relative humidity is preferably 60% to 70%. Higher humidity is beneficial to the survival and reproduction of microorganisms. If accompanied by low temperature, it will increase the risk of low temperature. When the humidity is low, the chicken house is dry, which is easy to induce respiratory diseases of the chicken. Especially when the chicken is in a dry environment for a long time, it may cause dehydration and weakness. Therefore, we must pay attention to the adjustment of the humidity of the house. In winter, the litter is relatively dry and should be sprinkled or spray disinfected frequently.
2. Temperature
The suitable temperature for laying hens is about 20 °C, and the minimum should not be lower than 13 °C. If the temperature inside the house is not up to the required temperature and the temperature difference is too large, it is necessary to manually increase the temperature and keep it as relatively stable as possible.
3. Harmful gas
The most harmful gas to chickens is ammonia, which stimulates the sensory organs of chickens, induces respiratory diseases, and reduces feed efficiency. When you enter the house, you can smell the smell of ammonia, indicating that the ammonia in the house has already exceeded the standard. Chicken houses that are warmed by coal stoves should be protected against carbon monoxide poisoning. When the harmful gas is excessive, take appropriate measures immediately, such as increasing the ventilation volume and changing the litter, so as to reduce and eliminate the harm to chickens.
4. Ventilation
When the air in the morning is relatively dirty, if it is necessary to increase the ventilation, it should be gradually increased. It is best to carry out at a high temperature at noon. It is better to use a shorter ventilation time and multiple passes. If the chicken is found to be disease-free, snoring and breathing, the dust in the house is full and the odor is very strong, indicating that the air in the house is extremely dirty, and ventilation should be strengthened immediately. However, to prevent thieves, it is common to install elbow-type ventilation on the leeward wall to prevent the chickens from being directly exposed to the wind.

What are the advantages of raising chickens in layer cages?
Now most farms have widely used layer battery cages to raise chickens, and automatic chicken raising equipment has become an indispensable chicken raising equipment for the majority of chicken farmers. In recent years, the market demand for laying hens has not expanded. In order to improve breeding efficiency, Raising chickens in layer cages has become a trend, so what are the advantages of raising chickens in layer cages?
- High level of automation: automatic feeding, drinking water, cleaning manure, wet curtain cooling, centralized management, automatic control, saving energy, reducing artificial feeding costs, greatly improving the breeding efficiency of farmers.
- Poultry prevention is good and effective prevention: the chicken does not touch the feces, which can make the chicken grow more vigorously and provide a clean and warm growth environment for the chicken, and the slaughter time is much earlier.
- Save the space and improve the stocking density: the cage density is more than 3 times higher than that of the flat stocking density.
- Frugal breeding feed: egg hencages can save a lot of breeding feed. Chickens are kept in cages, so the amount of exercise is reduced, the energy consumption is low, and the waste of feed is reduced. The materials indicate that cage breeding can effectively save more than 25% of breeding costs.
- Consolidation and durability: The complete set of caged chicken equipment uses hot-dip galvanizing technology, which is corrosion-resistant and aging-resistant, and its service life can be as long as 15-20 years.
6.Time saving: It is convenient for breeding users to manage chickens and save more time to deal with other things.
How to Adjust the Nutrition of Laying Chicken in Summer?
In summer, the temperature is getting higher, and the chicken's condition will be affected as the temperature rises. For poorly broiled chickens, feed intake will drop significantly, greatly affecting chicken health and egg production. How to adopt a reasonable method in the summer and adjust feed nutrition so that the health of the chicken and bring more production is a topic of concern for many farmers.
The addition of oils and fats in feeds can change the palatability of feed, prolong the stay of feed in the digestive tract, and increase the feed intake and digestion and absorption of laying hens. When adjusting the feed formulation, the protein content should not be increased but rather reduced. The content in the feed should be increased accordingly in accordance with the reduction in dietary intake.
