Analysis on the Law of Laying Eggs in Laying Hens
The morning and evening of the peak of egg production is related to the feeding and management conditions in chicken farm equipment for sale. The higher the limit of feeding during the breeding period, the faster the peak appears. In the flocking period, the flocks that restricted the light, the peak of laying eggs appeared earlier than the flocks that did not limit the light during the breeding period. After reaching the peak of egg production, the egg production rate can generally reach 93% to 94%, and the highest can reach 95% to 97%, maintaining 3-4 weeks, and then decreasing by 0.5% to 1% per week, which is a steady decline; The egg production rate at 72 weeks of age can still be maintained at 65% to 70%. The extent of the new comprehensive technology for large-scale safe chicken raising is affected by genetic factors, and there are certain differences in varieties or strains. Poor feeding management, flocks suffering from stress, disease or high ambient temperature, the actual egg production rate declines weekly.
This period of final production is quite short. Although the pituitary gland still produces gonadotropin, the egg production rapidly declines until it can not form an egg. The laying of the female poultry has a certain periodicity, that is, a certain egg laying pattern can be repeated. It is manifested by the fact that the female produces an egg or produces several eggs in succession, and then stops production for one day or more in poultry battery cage.
The key points of epidemic prevention that chickens need to know in layer cages
Laying hen cages raise chickens. The growth cycle of laying hens is short and the stocking density is high. Farmers should pay special attention to the prevention of chickens. Doing a good job of disease defense can reduce the incidence of disease.
Farmers should develop immunization procedures. Farmers should be based on the local disease epidemic status. Find out what diseases have occurred in the area before or now. Farmers must focus on prevention. Develop a reasonable immunization program.
Buy high-quality vaccines. Whether the immunization is effective has a lot to do with the vaccine selected by the farmers. The quality of the vaccine is related to the effectiveness of the vaccine. Farmers should buy regular biological manufacturers. Also need to pay attention to the production date, shelf life and so on.
Note that sick chickens cannot be vaccinated. When farmers are conducting epidemic prevention, sick chickens cannot be immunized. If the farmers vaccinate the sick chickens, it will accelerate the death of the sick chickens. So vaccinate the sick chickens when they recover.
Avoid immune stress. In order to avoid stress during vaccination. Farmers should pay attention to the use of anti-stress drugs 4 to 5 hours before immunization when vaccinating with eye drops and nose drops. Avoid catching stress that causes the flock to die.
The above are some things that farmers should pay attention to when immunizing chickens in the process of raising chickens with the automatic chicken breeding equipment shared by the farmers.
Light management of chicken flocks
Light is an important environmental factor affecting chickens. It is necessary to know that suitable light can stimulate the secretion of sex hormones in hens, enhance the activity of ovaries and fallopian tubes, accelerate the formation and discharge of eggs, and the development of fallopian tubes, thereby improving the production capacity of hens. We should pay attention to these techniques when using chicken poultry cage equipment to raise chickens.
Do not reduce the lighting time during the laying period. The first time of adding light is 18 to 19 weeks old, and the light is generally started by the standard weight of 18 weeks old. For example, the standard weight of 18 weeks of age is 1.55 kilograms, that is, the light stimulation is started with the weight of 1.55 kilograms, but no later than the end of 19 weeks. The addition period is determined according to the weight of the chicken group, and it is generally preferred once a week. The time for adding light shall not exceed 1 hour, and the period of addition shall not be more than twice a week, nor less than two weeks. According to the light cycle to determine the duration of the light, generally the first two light stimulation is better, if the light is applied once a week, it is recommended to add light for the first two times, and then increase by half an hour every week until 14~16 hours; If you add twice a week, split the one-week addition time into two. The peak lighting time must not be less than 15 hours. The upper limit of the illumination time is 16 hours, and constant illumination is applied when the upper limit is reached.
Be sure to consider the consumption and increase of the flock before adding light. The increase in illumination is mainly due to the fact that the chicken population does not meet the standard and needs to stimulate the flock to feed, thereby increasing the weight of the chicken population. Lighting management must take into account the effects of natural light length and seasonal factors to develop a reasonable lighting program. When supplementing the light, the power supply should be stable, and the floor area should be about 3 watts per square meter.
Brooding period. Both chicks and broiler chickens are in a growing period. At this stage, light management should promote the healthy growth of chicks and have a high survival rate, but prevent hens from reaching sexual maturity prematurely. Chicks can grow well under low light intensity, but in order to make them eat and drink as early as possible, the first week of light can reach 12 hours per day, and the light intensity can be larger.
Breeding period (7-20 weeks old). The main purpose of light management is to control growth and development, and to achieve sexual maturity at the appropriate age. Premature sexual maturity, not only the egg weight is small at the time of opening, but also due to insufficient maturity, it will be discontinued shortly after the start of production, and then it will not be stable and high yield. From the stage of young chicks to 10 weeks of age, the length of light duration does not have much effect on sexual maturity, while the age of 10-18 weeks is critical.period. The lighting time is short during this time. Chickens raised in closed houses are completely artificially illuminated, and the duration and intensity of light can be controlled.
Laying period. The principle of light management during laying period is to enable hens to start production and reach a peak at the right time, giving full play to their egg production potential. Therefore, the illumination time should be long, and it should not be gradually shortened, and the illumination intensity should not be weakened. During the laying period, it is generally used with increasing or constant illumination, but not less than 14 to 17 hours of light per day. Laying hens are very sensitive to light hours. Generally, they start from 21 weeks of age, and give chickens 13 to 14 hours a day. After that, they increase by 30 minutes per week and increase to 17 hours to maintain the peak of egg production.
After determining the addition period, do not change it at will. In the process of adding light, if there is a large difference between the actual body weight and the standard body weight, the lightening interval can be appropriately extended, but it must not be longer than two weeks at the latest. From the beginning of the light to the peak of the egg production, it is generally better to stimulate it continuously for more than eight times. The light intensity should not be arbitrarily changed during the addition of light, which has an effect on the growth and development of the chicken in the automatic poultry farming cage.
Three characteristics of automatic layer cage breeding
Until now, the chicken industry is still deeply loved by farmers. There are more and more farmers using modern equipment to raise chickens, so let's take a look at its characteristics.
-
Reduce manpower and reduce breeding costs. Use automatic layer cages to raise chickens. All equipment can work automatically. In this way, the farmers can save labor costs. The use of mechanized equipment increases labor productivity and reduces labor costs.
-
The automatic egg collection system can collect eggs efficiently. Its use will not only reduce the breakage rate of eggs, but also reduce labor costs.
-
It is easy to manage and reduce the risk of breeding. The use of automatic chicken farming equipment can ensure the environment of the chicken house. For example: automatic manure removal system regularly cleans manure. The chicken manure is cleaned out in time to provide a good environment for the growth of chickens.
-
Conducive to disease prevention work. The use of modern equipment for breeding reduces the mobile contact of staff in the chicken coop, which is conducive to the prevention and control of chicken diseases.
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.
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.
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.
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.

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.
Feeding nutritional requirements when using broiler cages to raise chickens
Many broiler farm cage manufacturers believe that the main task in the rearing period is to cultivate healthy, well-balanced chickens with a body weight that conforms to the normal growth curve to ensure timely production. Therefore, in production, we must pay full attention to the dietary coordination of growing chickens. The content of crude protein in the diet should be appropriately reduced, which can be gradually reduced from 18% to 19% during the brooding period to 16% to 15%.
At the same time, reduce the energy concentration in the diet. When compounding diets, low-energy feeds such as rice bran and wheat bran can be used to replace part of high-energy feeds such as corn to help exercise the stomach and intestines, improve the digestion of the feed, and make the growing chickens have a good body condition. Pay attention to supplementing vitamins and minerals. The content of calcium, phosphorus, selenium, zinc, etc. and the ratio of calcium to phosphorus in the diet should be appropriate.
During the rearing period, the feed should be changed at least twice at the age of 6-7 weeks and at the age of 16-18 weeks. There must be a transitional period for each refueling. It is not possible to change all suddenly, so that the chicken has a process of adaptation. Especially from the brooding period to the rearing period, the replacement of feed is a great turning point. The nutrient content of feed, such as crude protein content, has dropped from 18% to 19% to 15% to 16%. Changes in feed ingredients can easily change the palatability of chickens and reduce feed intake. If they are not managed well, chickens are prone to disease.
Therefore, the following methods can be adopted for feed transition. From the first 1 to 2 days of the 7th week of age, 2/3 of the breeding period feed and 1/3 of the breeding period feed are mixed and fed. For 5-7 days, use 1/3 of the brooding period feed and 2/3 of the rearing period feed to be mixed and fed. From the 8th week of age, they are completely fed with feed during the growing period.
The first kind of feed change method is relatively detailed, and it is often used when the composition of the chicks and feed species changes greatly. The third refueling method is relatively crude, and experienced farmers and broiler cage manufacturers believe that it is generally used when the composition of adult chickens and feed species changes little. The second refueling method lies between the two and has a wide range of applications.
The above are the precautions when using broiler cages to raise chickens. I hope that the above content will be useful for novice farmers.
