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.
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.
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.
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.
In the chicken raising equipment, what are the layer cage equipment?
Nowadays, laying hen farming has become a popular poultry farming industry. Layer cage equipment is also becoming more and more popular with poultry farmers. So what devices are commonly used? Today, the laying hen cage manufacturer will give you a brief introduction.
- Layer cage for sale. The use of chicken cages to raise laying hens can fully utilize the area ofthe chicken house to raise more chickens. Can increase the number of farmers breeding. And the cage covers a relatively small area. This can not only save the area of the chicken cagefor farmers, but also increase the number of farmers. When using laying hen equipment, the flock can be effectively isolated from manure. In this way, the chickens are prevented from contacting the feces and the spread of the disease is reduced.
- Automatic feeding system. The automatic feeder is specially designed for the construction of cages. The feeding machine has the advantages of strange layout, practical, time-saving and labor-saving, uniform feeding, low consumption, battery power supply, DC motor drive, low noise, convenient operation, flexible steering, small turning space, and convenient maintenance.
- Automatic manure cleaning system. The manure cleaner is widely used to remove the manure of poultry and livestock raised in poultry chicken cages in Ghana. It can realize unmanned management, automatic and timely cleaning of manure, arbitrary time setting, temporary manure removal, simple and fast operation, automatic manual conversion, convenient management and no need for many personnel. The chicken manure runs with the manure scraper to the end and falls into the manure removal belt and is sent to the manure truck to be pulled away, which can improve the environment in the house and reduce the occurrence of diseases.
- Automatic drinking water system. Water is an indispensable substance for raising chickens. From the point of view of saving water and preventing bacterial contamination, the drinking fountain is an ideal water supply building, which can realize automatic drinking water for laying broilers, and does not require farmers to manually feed water, which is highly efficient. Leaking drinking fountain.
Maintenance of laying hen breeding equipment in chicken farm
Nowadays, there are more and more chicken farms using farming equipment. Because the use of automatic poultry farm equipment price in ghana can reduce labor and increase the economic income of farmers, then we ca n’t just use unmaintained equipment, which will shorten the life of the farming equipment. So how should we maintain the breeding equipment?
First of all, in order to ensure the service life of the equipment, users are required to regularly fill the transmission box transmission sprocket and gears with lubricating oil when they are used once a month; Lubricate the manure system and the central egg delivery system. Clean the egg transfer roller and the surface of the manure roller in time to prevent the accumulation of debris to swell the manure belt or break the roller shaft.
Farmers should timely clean up the impurities in the soft and broken egg collection trays in the farm. The ventilation system should be adjusted appropriately for side wall ventilation and roof ventilation according to the season. The laying hens of the lighting bulbs should always be kept clean, and the maintenance of layer chicken cages price in nigeria should not affect the light intensity.
The dung cleaning system of the layered laying hen cages has a unique structure. A vertical decontamination belt is set under each layer of chicken cages, so that the chicken dung of each layer of chickens will be scattered on the decontamination belt. Under the action of vertical flowing air, most of the water in the chicken faeces Outside the house, the water content of chicken manure is greatly reduced. When the manure is cleaned, because the manure removal belt is flat and smooth, the chicken manure removed from the house is granular. Such chicken manure can be sold directly to farmers or processed into compound fertilizers, which not only improves economic efficiency, but also avoids Environmental pollution. The chicken manure has been air-dried in layers in the house without fermentation, and each time it is cleaned up, the ammonia concentration in the house is extremely low, and the air in the house is fresh. Reduced incidence of disease.
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.
Which Factors Affect Size of Eggs in Chicken Feed?
Studies have shown that within a certain range, the content of some trace components in eggs is significantly affected by chicken feed. The content of nutrients varies, which affects the quality and size of the eggs.
Protein and amino acid levels in feed, protein intake is the main nutritional factor that affects egg size. Adjusting the protein level of the diet can change the size of the egg. Each one increase or decrease in dietary protein levels, such as from 16% to 17% or 15%, can increase or decrease the weight of the egg by approximately 1.2 grams. In practice, it is best not to increase or decrease the protein by more than 1 percentage point each time. Amino acid nutrition is the essence of protein nutrition.
The effect of dietary energy levels on egg weight is mainly through feed intake. If the daily energy intake of layer hens is lower than the lower limit of the above values, the egg production and egg weight will be affected, and thus affect the protein's Food intake (or protein savings) allows hens to have higher protein levels for maintenance, egg production and increased egg weight.
Essential fatty acids play an important role in the factors that affect egg weight. Linoleic acid is involved in fat metabolism, so it affects the size of the egg through its effect on the yolk.

Reasons for the formation of battery chicken cages for laying hens
The most important thing in laying hens is the egg production rate. 60 years ago, the social demand for eggs increased rapidly, and the high mortality of free-range chickens and chickens could not meet the needs of the society. So the trend of using battery chicken cages for laying hens to breed chicken began.
With the advancement of technology, automatic chicken raising equipment is now very popular. Modern chicken cage systems in use today are clean, automated and efficient. Modern sheds include automatic feeding, drinking, climate control maintained at 23°C, ventilation, lighting, and manure and egg collection. This efficient system allows farmers to optimize conditions for bird health and produce eggs at relatively low cost.
In addition, the use of laying hen cages allows chickens to be well protected, not only to avoid the invasion of animals, but also to avoid the invasion of pathogens.
The length of the battery chicken cages is generally 1,800 square centimeters to 11,000 square centimeters. Chickens can move freely, drink water and eat in this space. Because the trough is next to the iron mesh of the chicken cage. And there are two drinking nipples in a chicken cage, which can supply sufficient water for chickens at any time.
Layer cages are sometimes referred to as battery hen cages. Because parallel rows in poultry cages using automated chicken equipment look a bit like rows of batteries within a battery. Over the years, caged egg farming has attracted the approval of most poultry farmers. The hens are well cared for in the chicken coop, and can achieve free drinking water, eating, and a good living environment brought by the automated manure removal system and automated environmental control system.
The technology of raising chickens in modern poultry cages is very mature. Its convenience is also recognized by many poultry farmers. If you are also interested or want to know more about automated chicken raising equipment, please follow me.
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.
