Laying hen cage manufacturers analyze the causes of calcium deficiency in laying hens
In the process of raising chickens in automated layer cages, the comprehensiveness of feed nutrients is the basis for improving the high yield of layer hens. Sometimes the egg shell becomes thin and easy to break, and the color varies from light to dark. It means that the laying hens are lacking in calcium.
The first layer lacks calcium content in the feed. Farmers should know that calcium is an essential nutrient substance for laying hens to grow and lay eggs. It should be adjusted according to the growth of the laying hens and the laying situation. Therefore, farmers should pay attention to calcium supplementation for laying hens.
The nutrients of calcium and phosphorus in the feed are not balanced. Farmers should pay attention to whether the nutrients in the breeding are balanced. Too much phosphorus will affect the absorption of calcium. Calcium and phosphorus affect the strength of the eggshell.
Long-term cage breeding and lack of light: Most farmers now use the method of raising chickens in layer cages to raise layer hens. Most of the chicken houses are closed, so the layer chickens cannot get effective light. Farmers need to purchase lighting equipment for artificial lighting. But if the farmers do not perform the proper order, it will affect the absorption of calcium in the laying hens. At the same time, when the supplemented concentrate calcium is less, there will be a lack of calcium.
The above are the several reasons why layer cage manufacturers have summarized the calcium deficiency of layers for farmers. I hope that the above description can bring some help to farmers.
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.
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.
Advantages of layer battery equipment
The layer battery equipment manufacturers tells the advantages of the layer cage. Do you know any advantages of the layer cage? is that clear? It doesn't matter if it is unclear. Let's talk about the breeding advantages of layer cages.
Chicken farmers should know that chicken cages play a big role in the process of breeding. Especially the layer battery cages, it is a good protection for eggs, let's take a look at some of the advantages of laying chicken cages.
The equipment plays an important role in the breeding, especially in the laying of laying hens. The first part of the laying hen cage and the cage door show its advantages. The density of the cage and the angle of the egg are more and more manifested from these aspects. The benefits of chicken.
The benefits of the cage: the upper and lower cages are completely staggered, often seen in 2 to 3 layers. The advantage is that there is no need to set up a dung board at the bottom of the cage. For example, the manure pit may not have a clearing system. The structure is simple, and the ventilation and illumination areas of each layer are large.
1. The mesh of the egg cage is relatively smooth, which can prevent the chicken from being injured in the foot.
2. The egg cage and the bottom net are encrypted, which can effectively prevent the fatigue of the ankle and laying hens.
3. The mesh of the egg cage is galvanized, which can improve the service life of the chicken cage. Generally, it can be used for 10 or 15 years.
4. High-density feeding of egg cages is more economical, and is conducive to epidemic prevention, and can also reduce the incidence of poultry diseases.
5. The unique door reinforcement design of the egg cage can effectively prevent the chicken from wasting feed when eating. And because the cage door space is increased, it is more convenient to manage the chicken.
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.
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.
Is the cost of raising chickens in layer cages high?
Now caged laying hens have become the first choice for farmers. But for many novice farmers who raise chickens peacefully, they have this question. Is it that the cost of raising chickens with automated chicken farming equipment is high?
The answer is that the cost of breeding will be high. The following will introduce why high-cost farmers are still willing to use it.
First of all, the chicken cage equipment adopts a multi-layer cage method. The chicken coop has three, four or more layers. Therefore, farmers using chicken cages can raise three, four times or even more laying hens. Cage raising increases the utilization of chicken house area. As the number of chicken houses increases, so does the income of farmers.
Multi-layer chicken cages raise chickens. The area above the chicken coop is also effectively used. And the feces produced by the chickens in the cage can fall on the ground or on the conveyor belt. The flocks will not come into contact with feces. This reduces the number of fecal infections. This allows the chickens to lay eggs earlier.
Laying hens are raised in chicken cages. Laying broilers live in chicken coops for a long time. The stocking density is relatively large, so there is very little space for chicken activities. If the activity of broilers is less, the energy consumption will be reduced, and the feed required will be reduced. Cage can effectively save more than 20% of feed cost.
Farmers use chicken farming equipment to raise chickens. It is very convenient to drink and feed. Farmers can save a lot of space to manage the flock and deal with other things. Improve the labor efficiency of farmers.
The quality of the chicken coop is good. Chicken farming equipment can be used for more than ten years. Farmers choose the hot-dip galvanizing process when buying. Buy duplex, anti-aging. Numerous batches of chickens can be raised.
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 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.
Farming Points and Management For Free-range Chickens
Farmers can choose the right brooding season in order to facilitate the grazing of ecological chickens. The best season of farming is in March to May, when the survival rate of brooding is high. By the middle chicken stage, due to suitable temperatures and long hours of outdoor activities, it can be fully exercised and exercised, resulting in strong physique, which is very beneficial to natural grazing, feeding and prevention of natural enemies in the future. Spring chicks are sexually mature and have long duration of egg production, especially chicks hatching in early spring.
Feeds on ecological chickens must be organic feed. Therefore, when planting ecological chicken feed ingredients, it must comply with the requirements of organic foods, and animal feeding supplements that are artificially supplemented must also comply with the standards for the production of organic foods. It is forbidden to add chemicals during the production of artificial feed to ensure the quality of ecological chickens. The quality of natural feeds depends on the natural environment. There are natural forages, mature fruit and various natural insects. Only ecological chickens have enough natural feed and nutrition to produce high-quality products with high nutritional value and nourishing properties.
