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.
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.
Is the chicken house disinfected way right?
We all know that if we want to raise chickens, this part of disinfection plays a decisive role in breeding. It is reasonable to reduce the incidence of disinfection, which greatly reduces the cost of breeding. If the disinfection is unreasonable, it will waste money and delay the disease. Increase the incidence of flocks and reduce our economic benefits. Today we will come together to see how disinfection is the most correct.
1. The general situation of the chicken battery cages is to disinfect twice a week, at least once a week, and more frequently in the summer.
2. Two or more disinfectant products must be used alternately in the farm.
3. It is very important to thoroughly clean the farm before disinfection. It is very important not to dust the house, the roof spider web layer is layered, the ground is not cleaned, and disinfection is started. The disinfection effect is very poor. It is the same as no disinfection. This is also a mistake that many farmers' friends tend to ignore and easy to make. Everyone must pay attention.
4. 3 days after the vaccination vaccine, do not disinfect the chicken farm, and do not disinfect the chicken farm equipment. Otherwise it will greatly reduce the effectiveness of the vaccine.
5. When disinfecting with disinfectant water, whether it is summer or winter, it is not possible to spray the disinfectant directly onto the chicken. Instead, it is sprayed on the top of the hall or above the chicken cage. It can fall naturally on the chicken body and cannot be sprayed directly onto the chicken. To prevent the chickens from catching a cold.
6. When disinfecting in winter, try to use the Chinese medicine disinfection to fumigation, which can effectively prevent the chickens from catching a cold.
7. When using disinfectant for disinfection, it should be disinfected strictly according to the ratio. Do not increase the proportion of disinfection at random, so that it will not increase the disinfection effect and increase toxicity.
In short, the disinfection of chicken farms is very rigorous. If we can properly disinfect, it will greatly reduce the incidence of chicken farms, reduce our farming costs, and thus improve our economic efficiency.
Three Effective Ways to Reduce Costs of Poultry Feed for Chickens
First of all, chicken can obtain higher economic benefits. Self-made feeds: At present, the prices of commercial compound feeds produced by the feed processing sector are relatively high. Farmers may purchase full set of chicken In order to reduce costs, it is best for farmers and chicken farmers to feed their own chicken. Use local produce or self-cultivated food and other agricultural and sideline products for food preparation and try to be as comprehensive as possible.
Secondly, purchase of finished feed and then re-preparation: In order to spend less to feed, you can buy a lower price of compound feed. However, due to its poor quality, in order to ensure the nutritional needs of chicken, you can add some homemade soybean cake, cottonseed cake, peanut cake and so on. You can also purchase more fish meal, blood meal, bone meal, amino acid, and other additives, and feed it evenly with the feed.
Thirdly, as the season changes, the feed intake of chickens will also change. In summer and autumn, where the temperature is higher, the feed intake of the chicken is reduced, and the protein feed and amino acid content of the diet should be appropriately increased. When the winter chickens are in season, the food intake will increase, the protein feed and amino acids in the diet should be reduced appropriately, and the amount of roughage should be increased appropriately to save costs.
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.
chicken house Construction Suggest
The construction of the chicken house is related to the breeding work of the chickens in the back. The scientific and reasonable chicken house can play a role in improving work efficiency and management convenience. Now I would like to
suggest the construction of the battery cage system for layer as follows:
layer chicken cage for ordinary window chicken houses
The chicken house has windows, which can use natural light and natural ventilation to save production costs. Generally, there is no mechanical ventilation device, and most of the brick and wood structure is used. The building form is
basically the same as that of common civil buildings, but it is often opened at both ends. Floor window and roof vent cap.
The construction cost of such a house is medium, and the environmental control efficiency is general. When the person controls the illumination, it is difficult to shorten the illumination time. Thorough disinfection is more difficult
and suitable for small-scale professional households.
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.
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.

Secrets of raising chicken management in winter
In the process of raising chickens, in addition to selecting reliable poultry equipment manufacturers. Experts believe that strengthening winter management is an important part of increasing egg production rate. Now let's talk about the management of chicken raising in winter.
In winter, the temperature is low, and the chicken consumes a lot of heat, so it is necessary to eat more feed. When the room temperature is lower than -5 °C, the chickens gather in a group, do not like activities, walk slowly, and the laying hens will also stop production. Below -10 ° C, the cockscomb will freeze. Other feeding and management conditions remain unchanged. If the room temperature can be raised to about 10 °C, the egg production rate can be increased. However, the room temperature is too high, and when the temperature difference between indoor and outdoor is very different, it is easy to cause a cold when the chicken is placed outside.
Therefore, the most suitable temperature in the room should be controlled at about 5 °C, so that the drinking water does not freeze, the chicken can disperse the activity, and the normal egg production is maintained. The method of heat preservation mainly makes the house tight, and there is no place for ventilation. It can also be densely fed and a windproof fence on the outside of the house and the playground. Thus, when the outdoor temperature is not lower than -30 ° C, the night temperature in the house can be maintained at 2 ° C - 3 ° C, 5 ° C - 7 ° C during the day, without burning fire for temperature. In areas where temperature is required, a fire wall can be built in the house to balance the temperature.
In winter, it is also important to keep the air fresh inside the house. Otherwise, due to lack of oxygen, it will affect the metabolism of the chicken and the egg production rate will decrease. Therefore, the vent should be opened frequently during the day. When the sun is sunny and the climate is warm, you can open the small window and then open the big window for ventilation. If the outdoor temperature is around 0 °C, the chicken can also be released from the house.
In winter, it is mainly based on house feeding, it is easy to accumulate manure, and the humidity in the house is high, which affects the health of the flock and the quality of the eggs. In order to keep the ground dry, a small amount of lime can be smeared when changing the grass.
In winter, not only should you pay attention to adequate nutrition, but also with a high-calorie grain feed. Long winter nights can increase the amount of feed when feeding the last pellets.
Drinking water should be kept warm, especially if you drink warm water in the morning to promote warming and promote exercise. In order to make the chickens exercise more, you can often feed the pellets in the sports field, or hang cabbage, radish, etc., so that the chickens can eat freely and run more. Conditional can be installed in the house to increase the light, one to warm, and the other to stimulate activities to promote egg production. Generally, the time between artificial lighting and daylighting is not less than 13 hours - 14 hours. Every other week, one-thousandth of potassium permanganate water is supplied in the morning, which can prevent chicken stomach and cornea from being ulcerated, and improve the rate of love and hatching.
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.
