CATDOLL : CATDOLL: Layer sterilization technology? Layer breeding technology?

1. Laying hen sterilization technology?

The commonly used methods for chicken farm disinfection can be roughly divided into three categories: physical disinfection, chemical disinfection and biological disinfection.

2. Laying hen breeding technology?

1.

First of all, when choosing the type of chicken, generally choose chickens with strong adaptability, strong disease resistance, strong foraging ability, and good tolerance to rough breeding. In addition, market demand should also be considered to choose breeds with good sales. It is best to choose excellent breeds of native chickens, so that the chickens raised are highly profitable.

2.

During the brooding stage, chicks generally grow normally in an environment with a temperature of 34 to 35 degrees. In order to ensure the accuracy of the temperature, in addition to checking the condition of the chickens, a thermometer should be hung indoors and the feces should be removed. In addition, Vino Chicken High Dimension Vitamin Supplement should be added to the feeding feed to promote growth rate, increase appetite, enhance resistance, meet a variety of nutrient absorption components, and improve breeding efficiency.

3.

The density of feeding and management should be moderate. Each laying hen should have enough food supply, keep the flock clean, and provide drinking water in moderation. The water quality should be clean, and laying hens should be fed regularly every day. If you want to produce more eggs, add Vinomycin to the feed during the breeding process to supplement minerals, improve production performance, improve feed utilization, reduce the occurrence of sub-health conditions, increase resistance, and enhance the overall quality and growth uniformity of laying hens. Improve the body shape of chickens and make the meat firm, thereby increasing the egg production rate of laying poultry, increasing egg weight, improving egg quality, and extending the peak egg production period. Improve the nutritional level of the diet in a timely manner. In order to reduce nitrogen pollution, we should also minimize nitrogen pollution and damage to environmental conditions, and keep them as stable or change gradually as possible.

4.

The chicken house should be well ventilated, even in winter, it needs to be properly ventilated and the air fresh, so that the chickens have a good environment to grow.

3. Teaching of laying hen breeding technology?

Step/Method 1

Temperature Control

For laying hens raised by farmers, the most suitable temperature environment for them to survive is 8℃-28℃. Too high or too low temperature will affect the egg-laying efficiency of chickens. Scientific research has found that every increase or decrease in the temperature of the environment where laying hens live will cause the egg production of chickens to decrease. Therefore, if farmers want to raise good laying hens, they must keep the temperature of the chicken house stable within a comfortable environment all year round to avoid the impact of the temperature difference on the growth and development of chickens due to the distinct four seasons in my country, thereby affecting the egg production rate of chickens.

Step/Method 2

Medication for disease prevention

If farmers want to raise high-yield laying hens, they must not be careless in epidemic prevention. Farmers must regularly test the antibodies of the virus in the chickens to avoid the phenomenon of large-scale virus infection in the chickens due to the failure of antibodies. They must always pay attention to the immunity level of the chickens, and cannot blindly vaccinate the chickens, and cannot increase or reduce the use of vaccines in the chickens on their own. Once the chickens are infected, they must take timely control of the disease in the chickens, and try to choose more sensitive drugs to control the disease.

Step/Method 3

Scientific ingredients

For chickens, different seasons require improved feeding according to the different nutritional needs of the chickens. In spring and winter, when the temperature is relatively low, farmers should appropriately add some high-fat and high-energy nutrients to the chickens to ensure that the chickens can effectively survive the low temperature season. Farmers cannot use the method of freely configuring feeds, and in the feed ratio, they cannot just add more corn to the feed. Because there is no ratio of multiple raw materials, the content of protein, vitamins, minerals and other ingredients may be in short supply, which will lead to reduced egg-laying performance of the chickens, soft eggshells, thin eggshells and other phenomena, and even cause the chickens to not have a peak egg-laying period at all. Therefore, when farmers change feeds, they must use scientific feed ratios and cannot add them blindly.

Step/Method 4

Timely light

Light is a very important factor for the growth of laying hens, especially for promoting the sexual maturity of the flock. Therefore, farmers must provide the flock with appropriate light, requiring 18 hours of light a day during the egg-laying period of the chickens. The most suitable light intensity is 5lx. Especially in winter or foggy seasons, the lights must be turned on in time for illumination, and the dimness must not hinder the egg-laying development of the chickens.

4. Core technology of laying hen premix?

Reasonable ratio, increase the feed intake of chickens, and increase the number of orders

5. 70-day laying hen breeding technology?

Layer breeding technology.

1. Breeding area

The breeding grounds for laying hens should be built far away from urban areas, major traffic routes and various factories to prevent excessive noise and pollution from affecting the growth of laying hens. It is best to build it in the mountains, where the air quality is good and pollution-free green breeding can be carried out. The chicken house should have a sports field, a rest room and a brooding room. The area should be controlled according to the scale of breeding, and disinfection should be carried out around the breeding farm to prevent bacterial infection and cause laying hens to be infected with diseases. The breeding environment of laying hens is very important for their growth. If the environment is not suitable, the laying rate of laying hens will be reduced at the least, and the laying hens will die at the worst.

2. Management during the brooding period

We need to control the time of introduction according to the different breeding areas. In the brooding room, we need to prepare water troughs, food troughs, etc., and sterilize them with high temperature. When brooding chicks, we need to pay attention to controlling the breeding density. It is not advisable to breed too densely to prevent some chicks from not eating enough and affecting their normal growth. And we need to do a good job of ventilation to improve the air quality in the chicken house. While ventilating, we also need to pay attention to controlling the temperature in the chicken house. In the first week of introduction, the temperature should be controlled at around 34 degrees, and then reduced by 1-2 degrees every 7 days until it is reduced to around 20 degrees.

3. Young chicken management

As in the brooding period, we first need to prepare the chicken coop for young chickens. The number of chickens raised in each cage should not exceed 10, and daily necessities should also be prepared and disinfected. The transfer time should not be chosen on rainy days to prevent the laying hens from being unable to adapt to the environment in time. Feeding should be carried out about 3 days after the transfer, when the laying hens gradually adapt to the environment. Let the laying hens eat freely, exercise appropriately, and feed twice a day. It is best to train the chickens to come back to eat when they hear a specific sound to enhance the growth ability of laying hens.

4. Egg-laying period management

When laying hens enter the egg-laying period, the egg container should be opened in time, and then an appropriate amount of soft paper should be placed at the bottom, and it should be replaced regularly according to the actual situation. Feed should be placed in a fixed position twice a day. Eggs should be picked up regularly. When laying hens just enter the egg-laying period, they should be allowed to form the habit of laying eggs at a fixed point. It is also necessary to check whether there are eggs laid outside the chicken house, and collect them in time to prevent them from being damaged. The water trough should be cleaned and disinfected regularly every day to reduce the base number of pathogens in the chicken house. In addition, the egg-laying situation, food, water intake, and feces of laying hens should be observed regularly. When abnormal conditions are found, the specific situation should be found out in time, and then symptomatic treatment should be carried out.

6. Shell-less laying hen breeding technology?

Shell-less laying hens breeding technology:

1. Create a suitable living environment for laying hens. To make laying hens lay more eggs, we must try to create a suitable growth and egg-laying environment for the chickens. We must take corresponding supporting feeding and management measures according to the changing rules of different seasons. In the summer season of high temperature and high humidity, we must pay attention to heatstroke prevention and cooling, strengthen ventilation in the house, maintain dry environmental hygiene, provide sufficient clean drinking water to the chickens, and appropriately increase the amount of green vegetables to improve the feeding ability of chickens. In winter, we must pay special attention to cold insulation and artificial lighting in the chicken house. The temperature in the house should be maintained above 13°C, with 15-16 hours of light, and the drinking water should be appropriately heated, and not cold water.

Second, pay attention to saving feed. The biggest expense of raising chickens is feed, which accounts for more than 70% of the total cost of raising chickens. If the feeding and management are not done properly, a lot of feed will inevitably be wasted. The measures to reduce feed waste are: First, the installation height, depth and length of the feed trough should be changed according to the different ages of laying hens and the cage density. The amount of feed added should not exceed 1/3 of the trough depth. Feed less and add more frequently to reduce the leftover food in the trough. The daily feed amount is determined by the egg production rate. Generally, when the egg production rate is 50%-60%, the daily feed amount for each chicken is about 95-100 grams. When the egg production rate is 60%-70%, the daily feed amount is 105-110 grams. When the egg production rate is 70%, the daily feed amount for chickens is 115-120 grams. When the egg production rate reaches more than 80%, the feed is not limited and the chickens can eat as much as they want. Second, beak trimming. Since chickens have the habit of scratching for food, the beaks of chicks should be trimmed at 7-9 days of age. At about 15 weeks of age, those with poor beak trimming need to have their beaks trimmed. Third, timely eliminate non-laying hens or hens with poor egg-laying performance. When the hens are transferred to the egg-laying house after rearing, they should be eliminated once. All underdeveloped, too small, too fat, sick, and listless hens should be eliminated. During the egg-laying process, broody hens, sick hens, disabled hens, and hens that have stopped laying should be eliminated at any time. In the late egg-laying period, the hens that have stopped laying should be eliminated. Hens with beards, pale faces, and shrunken crowns should be eliminated immediately. Chickens that are too fat or too thin should also be eliminated immediately.

3. Reasons for the decline in egg production

Environmental factors: Changes in lighting program or light intensity: such as changing the color of light at any time, suddenly stopping lighting, shortening the lighting time, weakening the light intensity, irregular lighting time, long and short, early and late, sudden lighting and stopping, forgetting to turn off the lights at night, etc. Severe lack of ventilation, long periods of no ventilation, etc. Attacks of natural bad weather: sudden attacks by heat waves, typhoons or cold currents without prior preparation or prevention. Long-term water outage: Long-term water shortage or water outage due to malfunction of the water supply system or forgetting to turn on the switch.

Feed factors: Significant changes in feed ingredients or quality problems in the diet can cause changes in egg production. For example, sudden changes in the types of raw materials in the diet, uneven mixing of feed, moldy feed, replacement of fish meal and yeast powder, high salt content, high amount of stone powder added, replacement of cooked bean cake with raw bean cake, forgetting to add salt to the feed, etc., reduce the chicken's feed intake and cause indigestion. Normal egg production rate and no weight loss of chickens indicate that the feed amount and the nutritional standards provided meet the physiological needs of chickens, and there is no need to change the feed formula.

Chickens are sick: acute or chronic infectious diseases can cause a sudden drop in egg production. For example, if a chicken is attacked by a highly virulent Newcastle disease, egg production often drops by more than 50%; infection with egg drop syndrome can cause egg production to drop by 20% to 40%. If mixed with other diseases, egg production can drop by more than 20%. In addition, if chickens are infected with infectious bronchitis, infectious laryngotracheitis, cholera, coccidiosis, Escherichia coli, avian influenza, etc., egg production can drop significantly.

4. Disease prevention

Reducing the number of dead chickens and preventing the occurrence of epidemics are the keys to the success of chicken farming. According to the scientific hygiene and epidemic prevention procedures for controlling the occurrence of chicken diseases, various vaccines should be injected according to the age of different chickens. At the same time, the chicken houses and utensils should be disinfected with drugs regularly, and the feces in the houses should be removed in time. The area around the chicken houses should be rid of rats to prevent rats and sparrows from entering the houses and bringing in the epidemic. In order to reduce the chance of the spread of the epidemic, the number of people entering and leaving should be reduced as much as possible, strangers should not be allowed to enter the chicken houses, and visitors are not allowed to ensure the safe operation of the chicken farm.

7. Green shell laying hen breeding technology?

1.

illumination

The ideal lighting time is 16 hours. If natural light is insufficient, artificial light should be supplemented in the morning and evening, and a programmable lighting controller should be used to keep the lighting on and off times, brightness, etc. constant.

2.

Temperature and ventilation

The suitable house temperature is 10℃~27℃, and measures to prevent heatstroke or keep warm should be taken to keep the temperature as close as possible. If it is sunny in spring or autumn, you can set up a forest for free-range breeding.

3.

After more than 3 weeks of feeding, the weight of the chicks can generally reach more than 0.3 kg, and they are ready for free-range grazing. At this time, they can be released into the woods, reservoirs, and meadows. The green-shelled laying hens catch insects, eat grass seeds and tender grass, and move freely in the vast fields.

4.

This period lasts up to 15 weeks, and the supplementary feed can be gradually reduced from 5 times a day in the yard to 2 times a day. When feeding twice a day, feed less in the morning when the fish are released, and feed more when they come back in the evening.

8. Comprehensive technical knowledge on raising laying hens?

1. Save feed. Laying hens are required to be fed twice a day, with high-energy, high-protein, low-calcium feed in the morning and low-protein, low-energy, high-calcium feed in the evening. This can regulate the egg-laying cycle, increase egg production, and save feed at the same time.

2. A good way to feed chickens: Know that chickens have two peak feeding times in a day: one is 2-3 hours after sunrise; the other is 2-3 hours before sunset. Feeding chickens at this time will increase egg production.

3. Incubate more hens. The main thing to consider before incubating is the shape of the eggs. The eggs should be short oval, with one end larger and the other smaller, forming an inverted triangle shape. The surface of the egg should be fine, and the chickens hatched are mostly hens. On the contrary, if the eggs are long oval, the head and tail are difficult to distinguish, and the surface of the egg is rough, the chickens hatched are mostly roosters.

4. Identify male and female chickens. Spread the wings of a chicken. If the feathers (primary feathers) on the wings are long and short (i.e. the feathers are long and short), it is a hen. If you see that all the feathers are basically the same length, it is a rooster.

5. Purchase chicks. It is best to purchase chicks from the end of February to the beginning of March. The temperature is relatively stable at this time. After 5 months of feeding, they will start laying eggs in August and reach the peak production period in October. At this time, good feeding and management should be maintained to make the peak egg production last for 2-3 months of the following year, which is just the time when poultry eggs are popular in the market around the Spring Festival, so the economic benefits are higher.

6. Adding 0.3% red pepper powder, 6% dried and crushed alfalfa leaf powder and 5% pine needle powder to the daily diet of chickens can deepen the color of egg yolks.

7. Long-term storage of eggs. When storing eggs, the tip of the egg should be facing upward, so that the yolk is located in the center of the egg, preventing the embryo from sticking together, and improving the long-term storage and hatching rate of the eggs.

8. Prevent fowl plague. When the chickens are 10 to 14 days old, use the IV series of fowl plague vaccine to drip into the nose, and at the same time, use 0.3 ml of the inactivated fowl plague vaccine to inject intramuscularly. Around 70 days old, use the I series of fowl plague vaccine to inject intramuscularly, and at 120 days old, use the I series of fowl plague vaccine to inject intramuscularly once, and at the same time, use 1 ml of the inactivated fowl plague vaccine to inject intramuscularly once, the protection rate can reach 100%.

9. High production. You need to understand the weight changes of the chickens. If the weight of the chickens does not increase normally, before the egg production decreases, you can increase the feed consumption to maintain the weight. If the feed consumption is obviously at a lower level, and the weight of the chickens increases normally and the egg production is maintained normally, you can maintain it.

10. Increase egg production in summer. The main reason for low egg production in summer is the heat, so measures and equipment to prevent heatstroke and cool down are necessary. The most effective way is to properly fry the feathers of the chickens. The method is to cut the feathers on the chickens' breasts, legs, and left and right wings, and keep the feathers on the neck, back, and tail. The length of the hair should not damage the chicken skin and body, and it should not be cut completely. It should be cut more during the hot summer.

9. What are the breeding methods and techniques for laying hens?

Layers are chickens that are raised to lay eggs. Eggs are the main source of income for laying hens. Unlike broiler chickens, the main focus of laying hens is to improve egg quality and maintain or increase egg production, rather than improving the quality of chicken meat. Scientific breeding technology is the prerequisite for high production of laying hens.

Feeding and management techniques for laying hens before laying

The weeks before laying are the transition period for hens from the growth period to the egg-laying period. In this stage, not only a series of tasks such as group transfer, selection and elimination, immunization, feed replacement and increased light are carried out, which cause great stress to the chickens, but also the physiological changes of hens during this period are drastic, sensitive, weak adaptability and poor disease resistance. If the feeding and management are not done properly, the egg-laying performance will be easily affected. The feeding and management of laying hens before laying should pay attention to the following aspects.

1. Preparation for transfer to a new group

Chicken houses and equipment have a great impact on the health and production of laying hens. Before transferring the flock to the cage, the chicken house and equipment should be inspected and repaired, and the feeding system, drinking water system, power supply and lighting system, ventilation system, drainage system, cages, cage racks and other equipment should be carefully checked. If there is any abnormality, it should be repaired in time, and the chicken house and equipment should be fully cleaned and disinfected. The steps are to clean the feces, dust on the floor, roof, and walls of the chicken house and the dirt on the equipment, and then rinse the chicken house and equipment with high-pressure water. After drying, spray disinfectant liquid for disinfection. At the same time, the items used should also be disinfected. In addition, the necessary utensils, medicines, equipment, record forms and feeds should be prepared, and feeding personnel should be arranged.

2. Transfer laying hens to cages

① Age of cage entry: Modern high-yield hybrid laying hens generally lay eggs at around 17 weeks old, so they must be caged before 16-17 weeks of age, so that the new hens have a period of time to get familiar with and adapt to the environment before they start laying, form a harmonious group order, and have sufficient time for vaccination and other work. If they are caged too late, the laying time will be delayed, affecting the increase in egg production rate. Hens that have already started laying may also stop laying due to strong stress such as group transfer, and some chickens may even develop yolk peritonitis, increasing the number of deaths and cullings.

②Selection and elimination: Modern high-yield hybrid chickens require good growth and development, uniformity and neatness. If they are uneven, it will seriously affect production performance. When entering the cage, the chickens that are too small, thin and weak, and the residual chickens with no breeding value should be eliminated according to the breed requirements, and the high-quality chickens with lively spirit, strong physique and appropriate weight should be selected.

③ Cage by category: Even if the feeding and management during the brooding and rearing period is good, there will still be some smaller and larger chickens in the flock due to factors such as genetics and feeding management. If all are eliminated, it will inevitably increase costs and the cages in the laying hen house cannot be fully utilized. Therefore, when cages are put, the smaller and larger chickens are left and placed in different cages respectively. Special measures are taken to strengthen management and promote uniformity. For example, chickens that are too small should be placed in the middle cage on the south side with higher temperature and sufficient sunlight, and appropriate nutrition should be added to promote their growth and development. Chickens that are too large should be appropriately restricted. According to the number of chickens that can be accommodated in the chicken cage, each single cage should be filled with enough chickens at a time to avoid the chickens that enter the cage first bullying the chickens that enter the cage later.

3. Vaccination of laying hens

Vaccination is necessary before laying, which is crucial to prevent the occurrence of diseases during the laying period. The immunization procedure is reasonable and in line with the actual situation of the farm. The vaccine source is reliable, well preserved, quality guaranteed, the vaccination route is appropriate, the operation is correct, and the dosage is accurate. After vaccination, the vaccination effect should be checked, and antibody testing should be carried out if necessary to ensure the vaccination effect so that the chickens have sufficient antibody levels to prevent the occurrence of diseases.

4. Deworming of laying hens

Deworming should be done before laying. For chickens aged 110 to 130 days, use 20 to 40 mg of levamisole or 200 to 300 mg of chloranil per kilogram of body weight, mix with feed and feed, once a day, for 2 consecutive days to expel roundworms, and use 100 to 200 mg of thiobisdichlorophen per kilogram of body weight, mix with feed and feed, once a day, for 2 consecutive days to expel tapeworms. When the coccidial oocysts are seriously contaminated, anticoccidial drugs should be used for 5 to 6 days after being put into the cage.

5. Lighting control for laying hens

Light has a great impact on the reproductive function of chickens. Increasing light can stimulate the secretion of sex hormones and promote egg production, while shortening light will inhibit the secretion of sex hormones, thereby inhibiting ovulation and egg production. Light control of laying hens can be used to stimulate and maintain egg production balance. In addition, light can adjust the sexual maturity of reserve chickens and make hens lay eggs in a uniform manner, so light control before and after laying eggs is very critical. Modern high-yield hybrid strains have the ability to lay eggs early. Appropriate light stimulation in advance can make the new hens lay eggs earlier, which is conducive to reducing breeding costs.

For chickens that meet the requirements or are slightly larger than the standard weight, the lighting hours can be increased to 13 hours at 16 to 17 weeks of age, and then increased by 20 minutes per week until the lighting hours reach 16 hours. For chickens with smaller weight, light stimulation should be started at 18 to 20 weeks of age. The lighting hours should be gradually increased. If the lighting time is suddenly increased for too long, it is easy to cause prolapse. The light intensity should be appropriate, not too strong or too weak. Too strong light is easy to cause pecking, and too weak light will not have a stimulating effect. For new hens raised in sealed houses, the light intensity before and after the start of production is 10 to 15 lux because the light intensity is too weak during the rearing period. For new hens raised in open houses, the light intensity is affected by natural light during the rearing period, and the light intensity is strong. Generally, the light intensity should be kept within the range of 15 to 20 lux before and after the start of production, otherwise the lighting effect will be poor.

6. Feeding and management of laying hens

Feeding before laying not only affects the increase in egg production rate and the duration of peak egg production, but also affects the mortality rate.

① Replace feed at the right time: The calcium deposition capacity in bones is the strongest 2 weeks before laying. In order to increase the production of hens, reduce the egg breakage rate, and reduce the occurrence of laying hen fatigue, the calcium content in the daily diet should be increased from 0.9% to 2.5% from 17 weeks of age. When the egg production rate reaches 20% to 30%, the laying hen diet with a calcium content of 3.5% should be used.

② Ensure feed intake: Before laying, free feeding should be restored to allow the chickens to eat enough to ensure balanced nutrition and promote an increase in egg production.

③ Ensure drinking water: When the chickens start to lay eggs, their metabolism is vigorous and they need a lot of water, so they must be guaranteed to have enough drinking water. Insufficient drinking water will affect the egg production rate and cause more prolapse of the anus.

7. Reduce stress response in laying hens

① Arrange working hours reasonably to reduce stress. It is best to arrange the transfer of chickens to cages and vaccination at night. The movements of catching, transporting and putting chickens into cages should be gentle. Add feed to the feed trough of the laying hen house before putting chickens into cages, and fill the water trough with water. Maintain appropriate light intensity so that the chickens can drink water and eat feed immediately after entering the cages and get familiar with the environment as soon as possible. Keep the work procedures stable and have a transition period when changing feed.

② Use anti-stress additives. There are many stress factors before the start of production. Anti-stress agents can be added to feed or drinking water to relieve stress. Commonly used ones are vitamin C, instant multivitamins, fumaric acid and the sedative chlorpromazine.

8. Hygiene of laying hen breeding environment

After being put into the cage, the chickens are unfamiliar with the environment, and a series of management procedures are carried out, which causes great stress to the chickens. As the egg production rate increases, the chickens have vigorous metabolism, poor resistance, and are very susceptible to pathogens. Therefore, epidemic prevention and sanitation work must be strengthened. Outsiders are prohibited from entering the breeding area and chicken houses. Breeders must disinfect before entering, keep the chicken house environment, drinking water and feed hygienic, and regularly disinfect the chickens and the inside and outside of the chicken farm to reduce the occurrence of diseases. In addition, pay attention to the use of some antibacterial drugs and Chinese herbal medicines to prevent the occurrence of Escherichia coli and mycoplasma.

9. Strengthen observation of laying hens’ behavior

Observe the feeding, breathing, excrement and egg production of the chickens, and solve the problems in time. Before and after the chickens start laying eggs, their physiological changes are drastic, and they are sensitive and restless, which makes them prone to hanging their necks and tugging their wings. More inspections should be conducted to detect and deal with them early to reduce mortality. Pay attention to observation and promptly detect chickens with prolapsed anus, chickens pecking their anus, chickens that are bullied, and chickens that are sick and disabled, and pick them out for treatment.

10. What are the techniques for breeding hemp-feathered green-shell laying hens?

1. Chicken house construction

The chicken house should be built in a ventilated sunny place, with a light-transmitting window every 3 meters. Perches, waterers and feed troughs can be placed on one side of the house. A small door should be opened on the sunny side, and a sand-covered playground should be set up outside the door to ensure that the chickens have enough space to move around.

2. Incubation

When incubating, eggs weighing more than 40 grams should be selected as breeding eggs. Artificial incubation technology should be used. The eggs should be incubated in batches at a constant temperature, and attention should be paid to the cross-interval. In the first 18 days, the temperature should be maintained at 37.8 degrees in winter and 37.5 degrees in summer. On the 19th day, the chicks should be transferred to the chicks. Pay attention to laying them flat, and the temperature should be maintained at 37.2 degrees in winter and 37 degrees in summer. The eggs should be turned over every 2 hours at an angle of 90 degrees. Generally, the eggs can be hatched on the 20th day, and the hatching is basically completed on the 21st day. Disinfection should be carried out before incubation and 30 minutes after laying to ensure the healthy growth of breeding eggs and chicks.

3. Feeding

Green-shell laying hens have different requirements for feed nutrition levels at different growth stages. Generally, the daily crude protein content of chicks is 20%, that of young chickens is 15%, and that of breeder chickens is 17%. The chicks are in the brooding period within 30 days after hatching. The most important thing at this time is to keep warm. The temperature should be kept at around 33 degrees within three days after hatching, and then reduced by 2 degrees every other week. They need to drink water before feeding, and are fed with complete chick feed 4 to 6 times a day. At the same time, the brooding room should be ventilated. As the chicks age, the stocking density should be gradually reduced.

4. Disease prevention and treatment

Disease prevention and control runs through the entire breeding process of laying hens, especially the prevention of bacterial diseases such as phyllosporins and Escherichia coli. The first drug is enrofloxacin, which can be added to the drinking water. Allowing chickens to drink water freely can effectively prevent these two bacterial diseases. In addition, drugs such as Tylosin and Doxycycline are used to prevent respiratory diseases such as Mycoplasma and Mycoplasma. Coccidiosis should be prevented around 20 days of age, and Newcastle disease vaccine and fowl pox vaccine should be administered at 7-10 days of age.
