Due to the development of broiler genetic breeding technology and the continuous improvement of broiler breeders' feeding technology, broiler breeding has increasingly become an important means for farmers to make a fortune. Broiler farming needs to be simple. For example, plastic greenhouses with small capital investment can be used for broiler farming, so the use of water, electricity and medicine should be reasonable. And all kinds of broiler breeding equipment should pay attention to maintenance to extend its service life, reduce unnecessary waste and reduce the cost of chicken breeding, thereby increasing the economic benefits of broiler breeding.

What should be paid attention to in broiler battery cage system?

1. Density

The density of broiler farming should not be too high, generally according to two-thirds of the actual farming amount.

2. Management

For broilers aged 5-9 days, 12-15 days, and 20-24 days, measures to improve immunity should be taken, and the infection of broiler bursal disease should also be controlled.

3. Expand the group

In the process of raising broilers, attention should be paid to expanding the group in time to ensure the freshness of the air in the chicken house.

4. Temperature

The editor suggests that broiler farmers can take the method of high temperature brooding, because high temperature is conducive to the absorption of the yolk of the young chickens to increase the maternal antibody, and the later
chickens are not prone to illness.

5. Drug addition

Drugs can be added when feeding broilers, which can effectively prevent the occurrence of certain diseases.

6. Light

Since the eyesight of the chicks is weak and the strong light is conducive to the feeding of the chicks, it is necessary to brood the chicks with strong light.

(1) Suitable temperature for layer cage system equipment: brooding temperature for egg chicks: 35-33℃ for 1-2 days, 33-32℃ for 3-7 days, and then decrease by about 2 to 3℃ every week, It is about 21-18℃ until 5-6 weeks old. Whether the supplied temperature is appropriate, in addition to observing the thermometer, the behavior of the chicks should also be observed. For example, when the temperature is normal, the chicks are active, have a good appetite, drink moderately, sleep quietly, and have a comfortable sleeping position, mostly lying prone. The chicks are evenly distributed throughout the brooding house; when the temperature is high, the chicks are far away from the heat source and their wings spread out When the temperature is low, the chicks are crowded and close to the heat source, crowded together, trembling, making bursts of cold-phobic noises, and appetite decreases. Chicks are more sensitive to cold and warm, so pay special attention to prevent the temperature from rising and falling, and try your best to keep the temperature balanced. When controlling the temperature, the temperature should be higher at night or in rainy and snowy days; during the day when the chicks are active, the weather should be warmer, and the temperature should be lower; the temperature of weak chicks should be higher, and the temperature of healthy chicks can be lower.

(2) Suitable humidity for layer breeding equipment: Humidity is closely related to the evaporation of water in the chicken body, body heat dissipation and the cleanliness of the chicken house.

① In the high temperature and low humidity, too much water will be lost in the chicken, which will easily cause the chicks to become dehydrated. In addition, due to the dryness, the dust in the house is flying, which can easily induce respiratory diseases.

②At low temperature and high humidity, the house is cold and humid, and the chicks are susceptible to colds, causing wet litter and gastrointestinal diseases and coccidiosis.

③When the temperature is high and humid, the heat in the body of the chicks is not easy to dissipate normally, sulking, decreased appetite, slow growth and weakened resistance. In general,

It is advisable to keep the chicken house dry for chicken layer cage to prevent bacterial reproduction and infection, but the relative humidity should not be lower than 40%. Suitable relative humidity: 60%-65% before 10 days of age, and 50%-60% after 10 days of age. When the humidity is insufficient, water can be sprayed on the corridor, ground, surrounding walls or flue in the house, or a water basin can be put on the heat source to evaporate water vapor to increase the humidity in the house; when the humidity is too high, a moisture-proof layer can be laid on the floor of the chicken house , Properly increase the temperature in the chicken house, strengthen ventilation, change the bedding frequently in the flat chicken house, remove the wet feces and bedding in the house in time, and prevent the drinking fountain from leaking.

How to effectively prevent disasters such as epidemics in chicken farms is indispensable for disinfection in advance. There are three main disinfection methods for chicken farms: physical methods, chemical methods and biological disinfection methods. Today, I will introduce these three methods of disinfection for automated chicken farms.

One. Physical method

1. Clean up debris, feces and other attached organic matter, dust, remaining feathers, etc. for easy cleaning.

2. The cleaning method is to flush the site and equipment of the chicken house with a high-pressure gun, which can reduce or eliminate pathogenic microorganisms on the chicken house and poultry farming equipment, as well as remove bacteria-carrying organic matter, ensure thorough disinfection, and achieve the purpose of disinfection. Cleaning includes cleaning the ground, supplies (including drinking fountains, troughs), as well as cleaning lighting facilities, egg boxes and other ancillary facilities.

3. Use sunlight and ultraviolet light to irradiate, and use ultraviolet light in a somewhat confined space will have a better sterilization effect. Therefore, light sterilization is of great significance to the disinfection of chicken sites, utensils and objects.

4. High temperature disinfection is used, and the devices or pens or grounds that can be disinfected with high temperature can be treated with incineration.

Two. chemical method
In the process of disease control, chemical disinfectants are used to clean, soak, spray, and fumigate chicken farms and items to achieve the purpose of killing pathogens.

1. Selection requirements for disinfection drugs: choose one with strong disinfection power and long duration; one with wide disinfection effect; strong penetration; easily soluble in water; stable in nature; harmless to humans and chickens; economical and applicable.

2. To ensure the effectiveness of the disinfectant, the following points must be done: remove the dirt; the concentration of the disinfectant must be appropriate; use different disinfectants for different pathogenic microorganisms; choose the appropriate disinfection time, temperature and environmental humidity; PH.

3. Biological disinfection
Biological disinfection is mostly through the accumulation and fermentation of feces, sewage, bedding, etc., or biogas fermentation, so that the pathogenic bacteria in them are killed at high temperatures, and the effect of disinfection and sterilization is achieved.

Hope to help customers who use fully automatic chicken poultry farm equipment in nigeria

Today we will bring you how to adjust the temperature of chicken poultry farming equipment, and we hope that through our introduction, you can better understand breeding knowledge.

1. The brooding method of heating equipment flue heating is more suitable for small and medium chicken farms. The flue is built with bricks or adobe. The larger brooding room can use a long flue, and the smaller brooding room can be surrounded by a field-shaped flue. When designing the flue, the diameter of the flue inlet should be larger. The smoke outlet should gradually become smaller to facilitate the circulation of heating and exhaust smoke, and prevent smoke from falling down.

2. Ventilation equipment The airtight chicken house must adopt mechanical ventilation to solve the problems of air exchange and cooling in summer. There are two types of mechanical ventilation: aspiration and exhaust. Aspiration ventilation uses a ventilator to forcibly send fresh air into the house to form a positive pressure in the house and exhaust the dirty air; exhaust ventilation uses a ventilator to The dirty air in the chicken house is forcibly drawn out, so that negative pressure is formed in the house, and the fresh air equipment mainly introduces what enters the chicken house through the air inlet.

3. The water supply equipment can use the hanging tower type automatic drinking fountain. This type of drinking fountain is suspended from the ceiling with a rope through a loop. The top water inlet is connected with the main water pipe by a hose, and the incoming water flows in through a control valve. The drinking water tray is sanitary and water-saving.

4. Fully automatic drinking water equipment breeding equipment. mainly uses troughs. Cage-raised chickens use long troughs. Automated feeding uses feeders and chain feeders for feeding. This feeding method can be used for flat-raised chickens. Feed from the feed bucket. Chicks should use feed trays, and the shape of the trough affects whether the feed can be fully utilized.

5. Lighting equipment currently uses incandescent lamps for lighting. Many chicken farms have installed timers to automatically control the lights on and off instead of manually turning on and off the lights, ensuring the accuracy and reliability of the lighting time. Fluorescent tubes can also be used for lighting, and the tubes are directed toward the ceiling so that the light is reflected from the ceiling to the ground. This scattered light is soft and uniform.

6. The egg laying equipment can be used to raise broiler breeders or flat laying hens using double-layer laying boxes. In addition to flat net rearing, breeding chickens often use overlapping or stepped breeding cages. Laying hens are basically caged. The implementation of cage breeding and caged chickens can make full use of space, increase breeding capacity, good sanitation, easy epidemic prevention, save feed, high egg cleanliness, and convenient management of chickens. Small group breeding cages can be equipped with special curtains at one end of the cage to shade chickens. How to adjust the temperature of the chicken breeding equipment can create a quiet environment for the hens to lay eggs.

Chicken and eggs are becoming the necessities of the masses day by day. The nutritional value of chicken and eggs is very high. If farmers want to obtain high benefits through chicken raising, they must improve the production performance of the chicken flock and improve chicken raising. Benefit, achieve reasonable and scientific breeding methods.

1. The use of Broiler Cage System to breed broilers: Intensive and large-scale breeding models are popular in the chicken industry nowadays. The use of cage-raising is the basis for intensive chicken raising, and the use of cages to raise chickens can also be Farmers increase the number of chickens raised. Chicken cages are a multi-layer breeding mode, so the area of ??the chicken house can be used well, and the chicken cages are easy to manage, which can improve the number and cost of the farmers. Increase the benefit of chicken breeding.

2. Preparing a well-balanced feed: Whether the feed is formulated properly or not will directly affect whether the nutrition in the chicken group can be balanced. Only when the nutrition is balanced can the layer and broiler chickens perform normal growth and production performance. The farmers need according to different chicken groups. Varieties, various nutrients required for different growth stages to prepare a reasonable feed, so that the layer broiler can get a nutritionally balanced feed at each growth stage.

3. Scientific feeding and management: Whether the health and growth and production performance of the chickens can be brought into full play is closely related to the feeding and management of the farmers in all aspects. Therefore, doing a good job in feeding and management is to increase economic benefits for yourself. Laying a foundation, there are many aspects of feeding management: environmental management, feeding work, feed nutrition, disease prevention and regular disinfection work, etc. are all tasks that need to be done by farmers.

4. Do a good job of Fully automatic poultry farming equipment for chicken disinfection and immunization: Disease is a killer that hinders the health of chickens and hinders farmers from obtaining high benefits. Therefore, preventing the occurrence of various diseases has become a work that farmers must do. At present, disease prevention is relatively Good means are frequent disinfection and memory vaccination of chickens. Therefore, these two tasks cannot be ignored by farmers and must be carried out scientifically and reasonably.

5. Reduce the stress of beak cutting and immunity: Beak cutting and immunization are the work that must be done in the process of breeding layer broilers, but these two kinds of work are more irritating to the layer broiler and easily cause the stress response of the layer broiler. The growth and production performance of laying hens and broilers will be affected by nutrition. Therefore, farmers must add antibiotics and vitamins to the feed during beak cutting and vaccination to reduce the effect of stress factors. The time for choosing beak cutting and immunization is also selected After dark or before dawn, do not disturb the chickens to prevent them from exploding.

Farmers who use stacked chicken cages to raise chickens also have a lot of worries. Not only do they need to use immunization vaccines in the chickens, but also to maintain the chickens’ time for basketing. However, it is very difficult to change materials when using stacked chicken cages to raise chickens. It is important to ensure that the nutrition of the flock is sufficient and stable, and do not neglect the change of feed.

Under the development of breeding automation, the layer chicken battery cage mode is widely recognized by the majority of layer farms. This breeding method has a small area and high space utilization. The layered cleaning of chicken manure can not only improve the utilization rate of chicken manure, but also It also reduces the degree of environmental pollution. At the same time, it reduces labor intensity and increases productivity. Although stacked cages have many advantages, the premise is to know how to use them and how to manage them. In addition to the conventional power system, a generator that matches the chicken farm must be required and can be automatically switched. Ensure that the light in the house is even, and you can install light bulbs on a staggered level or use row lights.

In order to ensure the service life of the equipment, lubricate the transmission parts such as the transmission sprocket and gears of the transmission box once a month during use. Clean the surface of the egg roller and the fecal roller in time to prevent the accumulation of debris from swelling the fecal belt or breaking the roller shaft. Clean up the impurities in the soft and broken egg collection tray in time. The ventilation system should be appropriately adjusted for side wall ventilation and roof ventilation according to the different seasons. Always keep the lighting bulb clean to prevent affecting the light intensity.

First, if only the driving roller rotates when cleaning manure, the manure conveying belt does not move, it may be stuck in the manure removal belt due to excessive chicken manure. The manure conveying belt should be run regularly and the expansion bolts at both ends of the driving roller should be tightened to remove foreign matter. If the chicken manure on the manure belt is thin, it may be that the drinking fountain is leaking, the connection of the water tank is not sealed well, and the chicken is diarrhea. To replace the drinking fountain, apply sealant to the joint.

Second, if the material cart does not move, it may be that the driving wheel turns, the pull rope does not move, the positioning plate on the driven wheel does not contact the travel switch, the track wheel and the guide rail are squeezed, and the motor is damaged. At this time, it is necessary to rotate the ratchet wheel of the feeder, tighten the rope, adjust the position of the travel switch to make it contact, correct the guide rail to make it parallel, and replace the motor.

Three. If the egg breakage rate is high, it may be due to the chicken pecking the eggs, the egg shell is thin, the claws on the automatic egg collecting machine are broken, the eggs falling from the cage net and the eggs on the egg belt collide, from the automatic egg collecting machine The egg that came out collided with the egg on the central egg line. You can use the electric shock line to change the feed formula, find the broken egg claw and replace it, use the egg blocking line to adjust the height of the egg picker to make it buffer or  customers who raise chickens in Ghana or Nigeria.

In laying hen breeding, it is important to ensure that the egg production of the laying hens is increased. Only when the egg production is increased, can the farmers' economic benefits in the later period be improved. Therefore, in the process of breeding laying hens, farmers are looking for effective poultry breeding equipment for breeding. In recent years, the effective layer breeding equipment recognized by farmers is the layer chicken cages. So what kind of help does the layer cage provide to the farmers in breeding?

1. When farmers use layer farming cages to raise chickens, the number of breeding per unit area will increase. After the breeding number of farmers increases, the egg production of their flocks will increase accordingly, which increases the economic benefits of farmers in the later period.

2. The bottom net of the layer cage and the angle of the egg sliding are designed reasonably, and the eggs will not be jammed or rolled out and broken. In this way, the damage to the eggs of the farmers can be reduced and the economic benefits of the farmers in the later period can be increased.

3. When using layer cages to raise chickens, the amount of activity in the flock will be greatly reduced, the feed conversion rate will be correspondingly improved, and the laying performance of the laying hens will also be improved, and the egg production benefits will be increased accordingly

4. When using layer cages to raise chickens, farmers can always observe the living conditions of the chickens. In this way, if there are special circumstances in the flock, timely measures can be taken for treatment to prevent the spread of the disease or the aggravation of the disease, and reduce unnecessary troubles for the farmers in the later period.

5. When using layer cages to raise chickens, new and old layers can be raised separately. This can improve the breeding efficiency of farmers and reduce feed costs.

The above is the help that the poultry farming battery cages can provide in the breeding process. I hope that through today's description, farmers can have a more comprehensive understanding and understanding of the layer cage tools currently used.

Poor feeding and management in summer can easily lead to an increase in the amount of broken eggs, and the broken eggs are not easy to store, resulting in certain economic losses. Therefore, layer farmers should take comprehensive measures to prevent the increase in damage to eggs in summer.

Under high temperature conditions, the feed intake of laying hens decreases, the egg production rate decreases, and the amount of damage increases. Therefore, nutrition control should be strengthened to maintain the heat balance of the chicken body. The calcium in the feed determines the thickness, strength and quality of the eggshell. Under normal circumstances, at the peak of egg production, the calcium content in the feed should be 3.4%-3.9%. Since the egg yolk enters the uterus in the afternoon, if the calcium supply is insufficient during the afternoon, it will affect the calcification. Phosphorus determines the elasticity and toughness of the eggshell. Therefore, when configuring the diet, the phosphorus content should generally reach 0.6%, and the available phosphorus should be 0.5%, and the ratio of calcium to phosphorus should be between 4-6:1. If the ratio of calcium to phosphorus is imbalanced, it will inevitably affect the absorption of calcium and phosphorus and increase the amount of broken eggs.

The most suitable temperature for laying hens is 17 ℃-23 ℃. When the temperature exceeds 30 ℃, the feed intake is significantly reduced, the water consumption increases, the feces are thin, the eggs are small and thin, and the amount of broken eggs increases. It is necessary to ensure good ventilation in the chicken house to ensure that the laying hens breathe smoothly under high temperature conditions; the feces should be cleaned in time to reduce the stimulation of bad gases in the chicken house; if necessary, install exhaust fans to promote the ventilation of the chicken house. In the case of high temperature, auxiliary cooling can be carried out by hanging wet curtains, placing ice cubes, spraying cold water, and building awnings.

Try to avoid loud noises from machinery and vehicles around the chicken house. In addition, adding 0.1%-0.3% vitamin C to the diet of laying hens can also alleviate heat stress, increase feed intake, and reduce egg damage. . In the feeding of laying hens, try to fix the breeder, feeding method and feeding time as much as possible to reduce the number of catching chickens. When performing vaccination, choose to reduce the light at night. Ensure that the laying hens have sufficient drinking water and clean in summer, check the sink every day, clean and disinfect in time. Pick up eggs twice in the morning and at least once in the afternoon. If conditions permit, pick them up again before turning off the lights at night to effectively reduce the number of damaged eggs. Choose a layer battery cage equipment with a reasonable design. Under normal circumstances, the diameter of the iron wire is 2.3-2.5 mm, and the angle of the bottom net of the chicken cage is in the range of 7-8 degrees, which not only ensures the moderate hardness of the iron wire, but also avoids the violent impact of the eggs caused by the excessive angle of the bottom net, and reduces the damage of the eggs. The odds.

Farmers may choose to purchase an egg collection machine, which is more efficient.

1. The stocking density is too high

The main form of laying hen production is small-scale and large groups. Due to the limitation of funds, space, equipment and layer cage system, or the breeders’ one-sided pursuit of the scale of breeding, the density of
brooding and brooding by breeders is generally high. The brooding density in the first week is generally 30 per square meter, but the actual level is twice as high. It is more common, even 2-3 times higher. In some households, the feeding density remains the same from entering the chickens to the cages, and they cannot be evacuated on time in the early stage. The 6-week-old body size and weight are difficult to reach the standard, which directly affects the quality of brooding and growing chickens. In the practice of layer production for many years, I have deeply realized that the stocking density is the primary factor limiting the performance of layer hens.

2. Poor ventilation

In the early brooding period, doors and windows are tightly sealed to keep the chicks warm. As the density increases, secretions and excreta increase, powdery materials are used, feathers and dander fall off, the air in the house is extremely dirty, and the chicks grow in In such an environment, tears, sneezing, arthritis, etc. are in a disease state that seriously affects the growth and development of chickens.

3. The effective positions of the feeder and waterer are not enough, resulting in poor chicken uniformity

Due to the serious shortage of effective space for brooding, the number of early buckets and drinking fountains is unlikely to be large. With the continuous increase of the chicken age and the physical development of the chickens, the chickens can only eat and drink several times in rotation without increasing the number of buckets and drinkers. The quantity and quality of each chicken's food intake are different. , Resulting in poor chicken uniformity. Different disease prevention and control measures, different lighting systems and other factors are also one of the reasons for the lack of peak egg production in the entire hen house.

4. Different batches of chickens in the same chicken house

Individual farms (households) put chickens of different ages in the same chicken house. Due to different breeding management, different disease prevention and control measures, and different light systems, the eggs of the whole chicken house are not seen. One of the reasons for the peak.

5. The maturity of the prenatal and sexual maturity are not synchronized

Generally divided into two situations, one is that the uniformity is less than 80%, the coefficient of variation is more than 10%, and the average weight is lower than the lower limit of the standard. It is seen that the egg age is relatively early and the egg production rate rises for a long time. The egg production peak does not go up, the peak does not go up continuously, the peak duration is short, the egg weight is light, and the death rate is high. The other is that the uniformity is less than 80%, the coefficient of variation is more than 10%, and the average weight is higher than the upper limit of the standard. It is seen that the egg age is late, the consumption of the whole period increases, and the feed-to-egg ratio is high.

6. Unstable light or insufficient intensity at the laying stage

Practice has proved that 14-15 hours of light per day for laying hens can meet the demand during peak egg production. It is necessary to switch the lights on time when adding light, otherwise it will disturb the reflection of the layer to light stimulation. The electric light should be installed at a height of 1.8-2 meters from the ground. The distance between the light and the light is equal. For a 40-watt bulb, the supplementary light should only be gradually extended. When entering the peak period, the light should be relatively stable and the intensity should be suitable.

7. Unreasonable arrangements for peak egg production

The peak period of laying hens is about 25-35 weeks of age, and the laying rate is generally above 85%. During this period, the laying hens have the most vigorous physiological functions. This precious period must be effectively used. If the chicks are raised in early spring The peak egg production period of chickens is in summer. Due to the hot weather, chicken intake is reduced. Most chicken farms have ineffective heatstroke prevention and cooling measures, or although there are certain measures, it is difficult to reach the most suitable temperature during chicken laying ( 18℃-24℃). In addition, due to the hot weather, artificial cooling or fog machine cooling is required in the house to increase the humidity in the house, and the E. coli is suitable for growth and reproduction. The chickens are prone to colibacillosis, which can also make the laying hens difficult to reach the peak of egg production.

In the process of raising chickens, Many farmers choose automated breeding equipment for breeding,the temperature of the chicken house is one of the important factors, which can affect the health of the entire chicken flock. No matter what kind of chicken it is, the demand for temperature is very high, and a little carelessness will cause disease. The temperature required in the different breeding stages of the chicken flock is also different. Chicken farmers must do well in breeding according to this standard, so that the chicken flock can grow better and produce higher benefits. The majority of chicken farmers can set the temperature based on the performance of the chickens. What are the aspects?

1. Group performance

The appropriate temperature is that the chickens are evacuated evenly, the body is stretched, and some chickens breathe with their mouths open as an indication. If they accumulate away from the heat source, the breathing rate will increase, especially the chest breathing, which is mostly too high; if it is close If you get together away from the heat source, the respiratory rate decreases, and the temperature is mostly too low. However, the premise of this indication is that the humidity is appropriate and the flock is healthy. If these two premises are lacking, it cannot be fully referenced.

2. Individual performance
If we enter the chicken house and find that there are many chickens stretched out, but the neck hair is upside down, the head is pierced or the neck is stretched down, it is mostly due to low humidity and high temperature that cause pneumonia. If you touch the wings with your hands and your abdomen is hot, you need to provide a relatively low temperature at this time. On the contrary, if you feel cold when touching the chicken body with your hands and your legs are blue, you need to provide a higher temperature.

3. Anatomical observation
Through the dissection of sick and dead chickens, we not only need to find the pathological changes of the viscera, but also to find the cause of the disease. Whether the temperature is appropriate or not, there is a better indication. If the trachea is dilated, elastic, or even bright red bleeding, there is thick sputum in the bronchus, the lungs are bright red or whitish, the volume is not shrinking, and there is foul-smelling water discharged from the stomach, the temperature is usually too high. On the contrary, the trachea is tense, there is phlegm in it, black blood stasis and necrosis in the lung, the water in the stomach is clear and odorless, and the stomach wall is black. Mostly the temperature is low.

The above is the introduction of knowledge about chicken. The proper temperature in the chicken house can make the chicken body stretch better. If the respiratory rate of the chicken is found to be too fast or too slow, the chicken house is a problem. In addition, if chickens have their heads down or their necks constantly stretched, chicken farmers should pay attention. Excessively high or low temperatures can cause discomfort to the flocks and cause pneumonia and other symptoms. In addition, it can also remove the sick and dead chickens to find the cause of the disease. The majority of chicken farmers can make judgments based on the actual situation of their own breeding.

When using battery layer egg cages for breeding, temperature has the greatest impact on chicken production performance. During the brooding period, the resistance of the chicks is poor and the temperature requirements are higher. During the growing period and laying period, the appropriate temperature is the guarantee for the chickens to perform their normal production performance. If the temperature is higher, the feed intake of chickens will decrease, the feed conversion rate will decrease, the weight gain of broilers will slow down, the weight of eggs will decrease, the quality of eggshells will decrease, the egg production rate will decrease, and the number of dead scouring will increase until a large number of hot dead chickens.

Low temperature will increase the maintenance needs of chickens, slow growth, increase feed-to-egg ratio and feed-to-meat ratio. In winter, low temperature and excessive temperature fluctuations in the chicken house will reduce the resistance of chickens, decrease egg production, and induce respiratory diseases in chickens. Until moulting is stopped, it can be seen that temperature is the primary environmental factor that causes heat stress in poultry and affects the health and performance of chickens.

1.　The effect of high temperature on chicken

Chickens are warm-blooded animals that maintain a constant body temperature through heat production and heat dissipation. Under high-density and intensive feeding conditions, the metabolic heat production of chickens increases with the increase in growth rate, but the heat dissipation capacity does not increase. The suitable temperature required by the chickens varies with the age of the chickens. The requirements for the temperature of the chickens in the first few weeks are extremely strict. Whether it is to use an insulated umbrella for partial heating or to use the entire chicken house for heating, the temperature of the area where the chicks are located must be guaranteed.

2.　The effect of low temperature on chicken

Low temperature will first increase the maintenance needs of chickens, increase the feed-to-meat ratio of broilers, decrease the egg production rate of breeders, and decrease the resistance of chickens to diseases. When the temperature of the chicken house is too low in winter, there is no guarantee of the ventilation required to maintain a good temperature, which will cause an imbalance in temperature and ventilation management, and increase the concentration of harmful gases such as ammonia in the chicken house in winter and deteriorate the environment. When the temperature difference in the chicken house is large, especially when the outside temperature changes suddenly, the heating or ventilation is not well coordinated, and the temperature in the chicken house fluctuates too much. When the temperature drops suddenly, it will cause cold stress. While performance declines, it will also cause respiratory diseases in chickens.

3.　 Application of air cooling effect

In the case of air flow, the temperature felt by the chicken is different from the actual temperature. Sometimes the effective temperature felt is very different from the measured room temperature. The higher the wind speed, the cooler the chicken feels. This is the air cooling effect. It has been tested and determined that in a high-temperature environment, airflow is conducive to convection heat dissipation. When the temperature is between 24°C and 33°C and the relative humidity is between 47% and 62%, and the wind speed is increased from 1.1 m/s to 1.6 m/s, the egg production rate can be increased. When there is no wind or low wind speed (>0.3m/s), the body temperature of the chicken is equal to the ambient temperature. When the wind speed>0.5m/s, the body temperature of the chicken will decrease accordingly. Therefore, the wind cooling effect should be fully utilized during the water curtain cooling period in summer, and the wind cooling effect should be minimized in winter.

There is no large-scale poultry farming equipment supplier in Mauritius, so when buying chicken cage equipment, you must think carefully and carefully compare the quality of chicken cages.

As we all know, the purpose of raising laying hens is to hope that they can produce some high-quality eggs to enable farmers to obtain a good economic benefit. However, during the laying period, some eggs are often broken, and the amount of broken eggs accounts for about the production. The total amount of eggs is 6-8%, so this brings huge losses to the farmers' economic benefits. Today, the farming equipment manufacturers mainly introduce to the farmers what measures should be taken to reduce the damage rate of eggs.

1. Increase the frequency of picking up eggs to avoid collisions, especially during egg-laying concentrated hours, the staff should act lightly when picking up and moving eggs in layer chicken cage .

2. Maintain the health of the chickens and reduce the occurrence of diseases. Many diseases will not only reduce the egg production rate, but also reduce the quality of the egg shell, thereby increasing the egg broken rate.

3. Meet the nutritional needs of chickens, especially the content of calcium and vitamin D3, and the content of phosphorus should also be appropriate. The ratio of calcium to phosphorus should generally be maintained at about 3.4-4.6:1. Farming equipment manufacturers remind farmers that too much or too little supplementation of chicken flocks will have an adverse effect on the flocks, so when supplementing the flocks of nutrition, they must be supplemented in a scientific proportion.

4. In the hot season, the temperature in the chicken house is relatively high. In order to reduce the heat stress of the chickens, farmers can appropriately increase the calcium content in the diet. The calcium content is generally maintained between 3.7-5%. Avoid more than 5%, and add baking soda and vitamin C to the drinking water.

5. To reduce the occurrence of stress factors, it is necessary to keep the environment inside and outside the chicken house quiet and comfortable, and create a good growth environment for the chickens.

6. Starting from the chicken group 50-60 weeks of age, implement a short-term hunger strike for 3-7 days. The egg production is the same as that of no hunger strike, but the strength of the egg shell is significantly increased compared with that of no hunger treatment, and the egg broken rate is also greatly cut back.

The above is the introduction of chicken poultry farming equipment manufacturers to farmers on how to reduce the damage rate of their eggs during the breeding process of laying hens. I hope that today's description can be of some help to farmers.
