Reasons for low laying rate of laying hens
Farmers who raise layer hens in poultry chicken cages all want to allow chickens to lay more eggs, but some of them have low egg production rates due to some reasons. Today we will discuss the reasons.
First of all, there are two reasons for the lack of egg production rate: feed and management. Farmers need to check whether the feed formula is nutritionally balanced, and check whether the temperature and humidity of the poultry house are in line with the growth conditions of laying hens.
Farmers also need to reflect on the rapid change of feed after the peak egg production period. This will cause the chicken to have a greater stress response and affect the chicken's feed intake. As a result, the nutrients obtained by the chickens are reduced and the egg production rate is reduced.
The other reason is that the noisy environment of the chicken house causes the flock to be agitated. For example, loud noises can easily frighten chickens. Or suddenly change the breeding environment, etc. In response to the above problems, farmers should strengthen the management of the chicken house breeding environment and solve the problems in time.
Farmers need to consider whether the chicken house has sufficient light. Because light has a greater impact on stimulating the physiological functions of the gonads and laying eggs. Some chicken farmers only use natural light instead of lighting, so that the light is below 16 hours. Some have supplemented the light, but the light bulb is too small or the degree is too small. Although there are 15W light bulbs, they are not cleaned in time and are covered by dust, etc. And the light is not enough, which adversely affects the egg production rate.
The above is the summary of the reasons why laying hens lay fewer eggs. I hope that all farmers who raise layer hens can use the battery cages for layer hens to summarize the above experience to better raise chickens.
A Type Poultry Cages VS H Type Poultry Cages in Chicken Farm
With the increasing number of large-scale chicken farms, it is more contradictory for chicken farms to choose automated poultry cages for equipment, and they do not know how to choose. The following poultry equipment manufacturers will introduce to you how to make decisions on the selection of equipment for your reference
A Type Layer Cages
The laying hen equipment is a type A chicken coop. You can choose to install two types of manure cleaning: scraper cleaning and belt cleaning. It is a relatively early use of laying hen breeding equipment. If your coop can hold 5000-30000 birds. A-type battery layer cages are very suitable.
Advantage:
- The cost is low, and the breeding density is higher than that of flat breeding.
- The open area of each layer of chicken coop is large, even if it is an open chicken house, the ventilation effect is good.
- Reasonable design, easy to operate,
- Easy maintenance and long service life.
- The easy-to-open spring-loaded door makes it easy to observe and move the pullets.
Shortcoming:
- The area is relatively large, and the space utilization rate is low compared with the H-type chicken cages;
- The labor intensity of workers is high;
- The chicken manure on the upper tierof the chicken cage will fall to the chickens on the lower tier, which is not conducive to the health of the chickens and the integrity of the feathers.
H Type Poultry Cages
Chicken cages are tiered on top of each other like buildings. This kind of equipment was developed later, due to the increasing shortage of land resources, less and less land can be used for breeding. Therefore, more and more customers increase the stocking density, just to save land, and the degree of intensification is getting higher and higher.
Advantage:
- Vertically battery chicken cages save more floor space, increase the number of feeding, reduce labor and management costs, and ultimately bring considerable profits to chicken farmers.
- There is a manure removal belt at the bottom of each cage, which is clean and hygienic, allowing the chickens to grow healthily and less pollution to the environment.
- Small footprint, high space utilization, easy to achieve intensive and large-scale breeding;
- Sliding cage door, the opening is convenient and large, and it is easier to catch chickens.
Shortcoming:
- It adopts closed type and automatic temperature control, otherwise it is difficult to control the temperature inside the chicken house.
- There are at least tens of thousands of chickens in a chicken house, and the risk factor is relatively high.
Based on the above situation, I believe everyone knows how to choose. The chicken farmer still choose the equipment that suits them according to their total amount of laying hens and investment.
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.
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.
What is the Best Chicken Farming Density?
The number of chickens per square meter of feeding area in chicken layer cages for sale is called the stocking density. The feeding and drinking position occupied by each chicken is also an indispensable condition for mastering the stocking density. If the density is too large, the chickens are crowded, the environmental humidity is increased, the feeding is uneven, the chicks are not well-developed, the disease and convulsions are susceptible, the chicks are weakened, the mortality rate increases, and the growth rate decreases.
The low density of chickens raised in wire chicken cages for sale is beneficial to the survival and growth of the chicks, but it is not conducive to heat preservation and is not economical. The density should be adjusted according to the type, variety, brooding mode, season, age, ventilation status of the chicks. Automated farming equipment cage brooding should be correspondingly increased with age, the density should be reduced by about 30% at 3 - 4 weeks of age, and by about 15% at 5-6 weeks.
Why modern chicken farming equipment is becoming more and more important？
In recent years, with the vigorous development of the chicken industry, the improvement of the research and development level of livestock breeding equipment has greatly promoted the development of automation, and the technology of chicken farming equipment has also achieved rapid development.
Because of the sharp increase in labor costs, among the modern chicken raising equipment, the most widely used is the stacked chicken cage, which has been recognized by the majority of farmers.
Therefore, a modern-scale chicken farm cannot be separated from the use of modern intelligent chicken-raising equipment. Modern intelligent chicken-raising equipment can be said to be the core of the normal operation of modern-scale chicken farms, while fully automatic battery chicken-raising equipment is a modern layer chicken farm. Indispensable basic equipment for breeding.
The battery chicken cages are a product that solves chicken raising equipment at one time. The cascading brooding cage is a product equipment that can be used for brooding. There is no need to replace the chicken raising equipment during the chicken raising process, which avoids the stress reaction of the chicken during the transfer of the chicken, and also reduces the labor cost for the farmers. Laminated chicken cages are made of hot-dip galvanizing technology and have been treated with anti-corrosion treatment. It is necessary to pay attention to daily maintenance. The service life will be very long, and the multi-layer design can raise a large amount at the same time and does not occupy space. The cascading brooding cage can be raised in a centralized manner. There is a matching nipple drinking system, which can set different drinking water according to the size of the chicken, and the cage is convenient to wash and easy to disinfect.
The extensive use of modern chicken farming equipment has improved the efficiency of breeding, and farmers can more easily realize intensive chicken breeding because of their use.
Layer cage manufacturers share the habit of drinking water for laying hens
The layer cage manufacturers believes that in the process of feeding laying hens, it is necessary to clearly understand the drinking habits of laying hens, especially the laying hens in the laying period. Therefore, the editor will analyze the drinking habits of laying hens living in poultry cages.
First of all, when using automatic chicken raising equipment to feed laying hens, it can be mastered by observing the drinking habits of laying hens. Through daily observation, farmers should be able to clearly understand the daily drinking water peak of laying hens. Generally speaking, the peak drinking water of laying hens will be in the three time periods of 8:00 am, 12:00 noon and 6:00 pm every day. Therefore, it is necessary to ensure the adequacy of water according to the peak time of drinking water.
In addition, when using automated chicken raising equipment to feed laying hens, you should also know that the water intake of laying hens in different seasons is also different. Therefore, it is necessary to carefully observe the drinking water of laying hens in each season, so as to feed according to different water intake, which will also help to improve the egg production of laying hens. In addition, generally speaking, the water consumption of laying hens is about 200 ml in spring and autumn, about 280 ml in summer, and about 110 ml in winter.
The above content is the drinking habits of laying hens analyzed by the layer cage manufacturers. I hope it can help farmers to understand the habits of laying hens and better develop the poultry farming industry.
Suggestions for building a chicken house
The chicken house has two types: open house (common house) and closed house.
The common form of open house is that there are walls on all sides, large windows on the south wall and small windows on the north wall. All or most of these houses are naturally ventilated and naturally lit, and the temperature and humidity in the house vary substantially with the seasons. Ventilation and lighting equipment is often required in this type of house to supplement the lack of ventilation and lighting under natural conditions.
Closed house is also known as a windowless house. The roof of the chicken house is well insulated from the four walls, and there is no window on all sides. The interior environment is adjusted by manual or instrument control. Artificial ventilation and light are used in the house to control the temperature, humidity and air composition of the house by changing the amount of ventilation.
So what are the structural requirements of the various parts of the house?
The foundation should be deep and strong. The floor of the chicken house should be 20~30 cm higher than the outside, moisture-proof, flat, easy to clean and disinfect.
The material with good thermal insulation effect is selected, and the heat insulation performance is good, which can protect poultry farming equipment.
Roof: In addition to the single-sloping roof of the chicken house with a small span, the double-slope type is generally used.

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.
How to ventilate the chicken house manufacturers
Ventilation in the house is a daily and important thing, and now the chicken factory is a closed chicken house, so the farmers will use some ventilation chicken automated poultry equipment in nigeria to properly ventilate the chicken house, the chicken The harmful gases from the house are discharged, so that the flocks can breathe fresh air. How should the house be properly ventilated?
First, to ensure the tightness of the house: the premise of using the equipment for effective ventilation is that the tightness of the house is better, because only the closed house can use the equipment to let fresh air enter the house. Therefore, this requires farmers to pay attention to the inspection of the tightness of the house, for the poorly sealed house, to find the place where the air leakage is serious, especially the front and rear doors, the slab and the water curtain In other places, in addition to the high temperature period, the vertical ventilation system is mainly used, and the wet curtain cooling system is used.
Second, to ensure the matching of the chicken group demand and ventilation in the chicken house: the farmers will choose to use the chicken equipment fan equipment for equipment ventilation, and then use negative pressure ventilation to improve the wind speed inside the house and ensure the ventilation effect. When using longitudinal ventilation (especially when using a wet curtain), close the small windows of the house. If you open the small window, the wind speed will be unevenly distributed.
Third, the use of air inlets and water curtains should be matched with the fan: the number of fans and wet curtains for chicken equipment should match the house to obtain good ventilation and cooling effect. The size of the air inlet should be matched with the fan, the purpose is to make the chicken The ventilation is even and effective, and the static pressure inside the house is appropriate.
Fourth, create a suitable somatosensory temperature: farmers should pay attention to whether the ventilation management of the house is effective, whether the chicken is comfortable, not only the temperature displayed by the thermometer and the thermostat, must be judged according to the somatosensory temperature of the chicken and the performance of the flock : So farmers can go to the type H of bettery cage system to observe the flock and see how their mental state.
