What are the factors affecting the efficiency of laying hens?
Under the premise of consistent species of laying hens and feed ingredients, the most important indicator affecting the efficiency of broiler breeders is the laying cycle, followed by the feed-to-egg ratio, and again the feed price, egg production rate, egg weight, and dead scouring rate.
Of course, these indicators are not completely isolated, but are interrelated. The effective way to increase the efficiency of laying hens should first be to prolong the laying cycle; second is to design a reasonable level of metabolic energy in order to reduce the ratio of feed to eggs and control feed unit price.
Strengthen feeding and management of your layer chicken cages for sale, reduce the incidence of laying hens The health of laying hens must focus on the laying period, because this period is the most important stage for laying hens to achieve a good economic benefit, and it is also a period when laying hens are susceptible to disease.
How to correctly understand the battery cages price list？
The production process and design type of chicken cages are designed according to different chicken breeds. Therefore, the most important thing for farmers to choose cages is to choose cages according to their chicken breeds. The cages and equipment widely used by farmers now include: layer cages, broiler cages, and brooding cages. Next, the poultry equipment manufacturer in Uganda will introduce three different types of chicken cage equipment to farmers in detail.
Chicken layer cages for sale: It is mainly composed of two types: A-type laying hen cage and H-type laying hen cage. If the farmer has more than 30,000 chickens, the H type is recommended. If the breeding volume is 5,000-30,000, A-type cages can be used.
Both cages are made of hot-dip galvanized material. Sturdy and durable, the service life can reach more than 20 years. The surface of the cage is smooth, which can effectively prevent foot injury and improve the survival rate. Moreover, the design advantages of the cage are mainly reflected in the front net and cage door, as well as the cage density and egg rolling, which also reflects the interests of the growth of laying hens.
Broiler cages: The main broiler cages currently on the market are sandwich broiler cages. This cage is also made of hot-dip galvanized material. According to the growth characteristics of broilers, in order to overcome the breast inflammation caused by the hard bottom of the cage, the cage is made of high-quality steel. During the growth of broilers, there is no need to transfer the cages from the chicks to the broiler market, reducing the trouble for farmers to catch chickens and avoiding some adverse reactions.
Brooder cage for sales: The chick cage is a kind of cage specially made for chicks. The brooding cage is made of galvanized low carbon steel wire, which has strong tensile and compressive properties. Using chicken cages to raise chicks can better observe the growth status of chicks and facilitate farmers to eliminate them in groups.
The above is the battery cages price list shared by poultry equipment manufacturers. Hope to be able to provide guidance for poultry farmers when choosing a cascading chicken cage system. If you are interested in chicken cages, please continue to pay attention to our website for more information.
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.
Maintenance and maintenance of automatic layer breeding equipment
If a breeding farm wants to be industrialized, large-scale breeding is inseparable from automatic layer breeding machinery and equipment. Automatic layer breeding machinery and equipment are good assistants to assist layer farmers in the breeding work. Nowadays, the chicken breeding equipment is very good. Mechanical automation can be applied for a long time. This requires farms to carry out timely maintenance and maintenance of machinery and equipment, so as to ensure that all machinery and equipment can be maintained for the long-term normal work of the farm. The working efficiency of the chicken farm is the maintenance and maintenance of the following automatic layer breeding machinery and equipment.
The key of automatic layer breeding machinery and equipment includes: automatic manure cleaning machine, automatic feeding machine, automatic egg picking machine, each of which will describe the key points of maintenance of machinery and equipment.
1. Automatic manure cleaning machine: After the farm has applied the manure cleaning machine for a period of time, the manure removal belt will increase and increase the slack. Maintenance of rolling bearings and rubber sticks. Rolling bearings should be added with unsalted butter on time. The glue sticks should be kept tight and not loose. In addition, many farms have a roll-up of manure removal opportunities. Farms will remove manure belts in passive rolling. The position of the barrel can be leveled.
2. Automatic feeder: When the feeder is in use, the farm must pay attention to the fact that no items can be placed on the feeder, otherwise it will cause the motor to withstand too much force and burn the motor. The application of the feeder Make sure that the transmission chain and gears have a certain level of lubrication, otherwise the lack of lubrication will destroy the equipment. The farm should pay attention to regular maintenance. The feeder is mainly produced by skin to transport concentrated feed, so the farm should be maintained regularly Is the transmission belt intact? Is the level of tightness moderate? The control cabinet of the feeder will have a lot of dust due to dust caused by the concentrate. In the long term, it will cause short-circuit failure of the internal power circuit. The farm should carry out the removal on time.
3. Fully automatic egg picker: When the farm uses an automatic egg picker, it is necessary to pay attention to the detailed learning and training of the appropriate operation steps of the machine equipment. If the wrong operation is very easy to cause damage to the machine and equipment, use the egg picker After that, you must pay attention to frequent disinfection and sterilization, because some chicken excrement, feather dusters and other items containing pathogens are inevitably left in the whole process of application of machinery and equipment. If you have been using a machine that carries pathogens and does not often clean up If the equipment is available, the quality of the eggs will be reduced.
How to ensure the laying rate of laying hens in summer?
The high temperature in summer will affect the laying rate of laying hens to varying degrees. Here are some practical methods to ensure the high yield and stable production of laying hens raised in automatic chicken battery cage density through the summer.
Implement strict sanitation and disinfection measures
Summer spray disinfection can not only kill germs and purify the air in the house, but also lower the temperature of the house. It should be carried out at 10 am and 3 pm, but attention should be paid to the spray speed and the height should be appropriate. The spray diameter should be moderate. The disinfectant used must be efficient, non-toxic and side-effects, strong adhesion, and low irritating odor. So as not to induce respiratory diseases in chickens. Cause unnecessary losses.
Protect the chicken's own cooling and heatstroke prevention behavior
In order to adapt to hot weather conditions. Chickens often have some instinctive behaviors. If you open your mouth to breathe in order to dissipate heat, spread your wings. Increasing the contact area between the epidermis and the air and facilitating conduction and heat dissipation are all instinctive responses of chickens to adapt to high temperatures. Should be protected.
Use automatic ventilation system
When the temperature exceeds 30°C. The ceiling fan can be turned on to cool down the open type chicken house, and the closed type chicken house can adopt the longitudinal ventilation method to cool down. That is, an energy air outlet is set at the front door of the chicken house, and an exhaust outlet is set at the back door. A certain number of high-power exhaust fans are reasonably and evenly set up according to the size of the chicken house, and the west side windows are closed when the wind is active to prevent hot air from being injected. After the fan is turned on, the discharge of dirty air in the house and the injection of outdoor fresh air can be accelerated, effectively reducing the temperature of the house.
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.
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.
Four key points for raising chicken to supplement light
In the process of raising chickens in laying hens, the farmers know that the hens need reasonable illumination, and the natural light often does not achieve good results. Therefore, when the chickens are illuminated, they need to use artificial lighting equipment for artificial replenishment. Reasonable illumination is beneficial to the growth and production performance of laying hens, so it is a very important task. The author reminds farmers to pay attention to the following four points in addition to the time to light and the number of lighting equipment:
1. The chicken farming equipment illumination should be stable: the time for the average farmer to choose to supplement the light for the laying hens starts from the age of 19 weeks. When the light setting time is set, the light should be slowly increased from short to long, increasing by half an hour every week. It is appropriate. Farmers should pay attention to the fact that when the light is increased to 16 hours a day, it should be kept in stable light, and then the daily light can not be long and short. The best way is to add light every morning and evening.
2. The intensity should be suitable: the farmers should pay attention to the light intensity of the lighting equipment. For normal laying hens, the required light intensity is generally 2.7 watts, but the multi-layer culture mode of the egg cage culture, so the bottom layer The flocks are not easy to feel the light, so it should be improved when setting the light intensity, generally 3.3 to 3.5 watts per square meter.
3. The illuminance should be uniform: the farmers should pay attention when installing the lighting equipment. We suggested that the bulbs installed in the chicken houses of the farmers should be 40 to 60 watts, and then the height of the lamps should be set at about 2 meters. The distance between the bulbs is recommended to be about 3 meters. In addition, the farmer should pay attention to the fact that if your house needs to install more than two rows of bulbs, you should cross them so that the light is even, the distance between the wall and the wall. Should be half of the bulb spacing, should also pay attention to replace the broken bulb at any time, wipe the bulb once a week to maintain the proper brightness in the house.
4. It is advisable to use red light: there are many kinds of light colors in the lighting equipment. Farmers should pay attention to the different light colors of the lighting equipment when they choose, and the wavelengths are different. Tests have shown that hens under red light have higher egg production rates than hens under other light conditions when other conditions are the same, so it is recommended that farmers choose red light equipment.

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.
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.
