How to manage laying hens before they give birth? What is the reason for the early laying of laying

Eggs are more common agricultural and sideline products on the market, these years, eggs are loved by everyone with their low cost and rich nutrition, and have become an indispensable existence in family life. It is precisely because the prospect of eggs is very good, so many farmers began to breed laying hens, many people think that laying hens are very simple things, do not need special management, I think this is not right, before the laying hens are produced, they need careful management in order to produce high yields.

First of all, before laying hens, they should be given a stable living environment.

Farmers know that chickens are a particularly timid animal, there have been news reports, because of fireworks, resulting in chickens being frightened, a large area of death, noisy environment is not only not conducive to the healthy growth of laying hens, but also affects their egg production, so before the start of production, must arrange a quiet and stable environment for laying hens, so that they can lay eggs smoothly.

Secondly, before laying hens, they should be given the right temperature.

Layers do not lay eggs at all temperatures, and their egg production is closely related to temperature. In daily life, we found that the ** of eggs in summer is relatively high, because the high temperature has a huge impact on the egg production of laying hens. Laying hens can only produce eggs in large quantities between 15 and 22 degrees Celsius, and too high or too low a temperature can affect egg production.

Third, before laying hens, to ensure basic nutrition.

Whether it is people or other animals and plants, are in need of nutrition, only adequate nutrition, laying hens can grow well, only the body of laying hens is good, there will be a high egg production, so before laying hens, be sure to add meals to them, feed should also increase some nutrients accordingly.

Fourth, before laying hens, it is necessary to ensure sufficient light.

As the saying goes, all things grow by the sun, and the healthy growth of laying hens also needs light, which not only affects the health of laying hens, but also directly affects the laying hens. If you want to increase the egg production rate, you need to increase the amount of light. For closed chicken houses, if natural light is insufficient, artificial light should be supplemented.

1.Increase the light. 2. Calcium supplementation and feed exchange. 3. Keep the chicken coop quiet. 4. Increase the amount of feed feed according to body weight, the amount of feed required to maintain body weight is increasing, egg production nutrition, and feed should be increased at this stage.

Hygiene, ventilation, adequate water for the chickens, vaccinations for them, and lighting for them.

It is necessary to do a comprehensive inspection, deworming and epidemic prevention, and do a good job in all aspects of inspection. Inspect the chicken coop and disinfect it thoroughly.

In rural areas, almost every household raises laying hens, so that they can eat authentic native eggs. If the quantity is large, native eggs can also be used**. Sometimes laying hens start early, what is the reason? How to solve this problem? Here's what I'll tell you about.

1. What is the reason for the early production of laying hens?

Many chicken farmers in chickens, in order to improve the egg production rate and reproductive efficiency, the use of early brightening, egg production and other methods, to encourage laying hens to start the egg production period in advance. During the feeding period, the laying hens have certain requirements for light intensity and duration. If the light time is too long and the intensity is too high, it is easy to cause the laying time of the laying hen to be too early.

Therefore, if the breeding period is in the winter solstice, summer solstice and other natural sunshine periods with long natural sunshine, the light time is not adjusted in time, which is a major reason for laying hens to start laying eggs too early.

2. What is the harm of early production to laying hens?

If the hen lays eggs too early, it will greatly affect the laying performance of the layer and the body of the chicken. Laying hens start laying eggs too early, resulting in very small egg production, low egg weight, low egg production rate, and short peak egg production. After the peak period, the laying rate of laying hens also decreases.

For laying hens, the bones and muscles of the chicken are not fully developed, affecting the normal weight gain of the chicken itself. The resistance of the laying hens decreases and may age prematurely. In addition, it is prone to undesirable phenomena such as dystocia and anal pecking, which leads to an increase in mortality and diarrhea rates.

3. Measures to solve the problem of premature birth of laying hens.

In view of the phenomenon of laying hens laying eggs prematurely, different solutions should be proposed according to the actual situation. If the laying starts too early, we need to reduce the light intensity and shorten the light duration. The daily lighting time should not exceed 16 hours.

And feed the laying hens in time before laying eggs, and for the laying hens with prolapse of the anus, combined with oral drugs for local **. As for the chickens that have been pecked, the general situation is more serious and basically loses their value, so it is necessary to pay attention to timely elimination.

4. How to prevent laying hens from giving birth too early?

For laying hens that have not yet laid early, prevention should be the main thing to avoid early production. First of all, chicken farmers should strengthen their own knowledge reserves, do not rush in the name of production, and use various methods to advance the laying time of laying hens. This will cause losses, when the laying hen reaches 10-20 weeks of age, the daily light time should be kept at about 12 hours, not too long and not too strong.

For chickens grown during the winter and summer solstice, adjustments need to be made to their specific growing conditions. If you want your hens to start producing earlier, you need to make sure that their physical and sexual maturation are synchronized so that the peak laying period lasts longer.

The above gives you a detailed introduction to the causes and solutions of early laying hens, under normal circumstances, in the process of raising chickens to do a good job of preventive measures to avoid the occurrence of early laying hens.

In this case, you must adjust your food ratio, which may be related to the food ratio, pay attention to nutrition, most of them are caused by problems with the appropriate ratio, and you must match them in accordance with scientific methods.

Reasons for too long a light period. Avoid exposing eggs to the sun too early, keep the right amount of temperature, and keep the light so that you can solve the problem.

First of all, scientific feed feeding, do not increase or decrease feed at will. Laying hens must be changed before giving birth after feeding, generally at 18 weeks of age. The main reason for changing the feed is that the production of chickens needs calcium supplementation.

If calcium supplementation is too early, the growth of chickens does not have the ability to absorb the function of rectifying the flock is very important, before the flock of chickens should be caught and fed separately in a timely manner, in order to ensure the uniformity of the flock, and the weak chicks are fed with special "care" of the weak chicks, and the individual without feeding value should be decisively eliminated.

At this time, it is very important to control the environmental factors, the suitable temperature is 13 23, not less than 5 8 in winter, and not higher than 30 in summer. It is advisable to keep the relative humidity of the house at 60-70%. Pay attention to the ventilation of the chicken house, the carbon dioxide content in the laying hen house is less than the first to select the breed.

High-quality species are the key to breeding broiler chickens, and they should be selected with fine skin, delicious meat, strong resistance, and small and medium-sized size. If you choose laying hens, it is, of course, Hailan Brown and Jinghong No. 1.

The rearing diet of 1 3 + the laying period of 2 3 is fed for two more days, and then it is changed to the laying period diet, and the whole transition period is completed in about one week. In the future, the increase of feed nutrition should gradually increase with the increase of egg production rate, and do not increase too violently to grow chickens too early, calcium supplementation is not conducive to calcium deposition in the bones of hens. This is because during the reproductive period of the hen, many bones from the inner wall of the bone cavity give birth to some interlaced small bone needles, which have the function of storing calcium, and the growth period does not have these characteristics.

The new premises for raising chickens need to be disinfected, and the brooding room is disinfected with 5 to 6 percent lime water. If it is an old site, the floor needs to be cleaned, and hygiene is the most important thing. In winter, it is especially necessary to do a good job of keeping warm, and coal stoves and boilers can be placed in chicken farms, and chicken farms should be selected in high terrain, sheltered from the wind and facing the sun.

The environment should not only be quiet, but also convenient and pollution-free for drinking water. It is also ideal in orchards, tea gardens, bamboo forests and other sites where there are no diseases. It is also necessary to build a plastic greenhouse or grass shed to protect from rain, cold and sunlight.

1. Deworming and epidemic prevention should be done as soon as possible, and the epidemic prevention should be done comprehensively before the chicken lays eggs, and the epidemic prevention time should be carried out separately from the epidemic disease, and it must not be completed at one time. This is not only a great stress for the flock, but also affects the normal absorption of the vaccine. Rural chicken farmers should pay attention to the immunization time reasonably, and arrange the deworming at around 110 days of age.

2. It is very important to rectify the flock, and the weak chicks should be caught and fed separately before the chickens are fed in a timely manner, so as to ensure the uniformity and uniformity of the flock, and the weak chicks are fed with the weak chicks to support the special"Take care of", individual no feeding value should be decisively eliminated. For this reason, the beak should also be cut off once in a timely manner according to the actual situation.

3. Check the chicken cage is inseparable, if the chickens are basketed before the start of production, the chicken cage should also be carefully inspected, thoroughly disinfected, and repaired in time to repair the damaged or deformed parts to prevent the eggs from breaking. According to actual production, it has been found that the egg breakage rate due to chicken cages has been high.

4. It is indispensable to adjust the diet, before and after 110 days of age, if the growth and development of chickens meet the standards, it can be adjusted in a timely manner and change the feed to meet the egg production needs of the flock. It can be directly changed to egg laying feed (do not add shell powder first), and the full price of the laying hen feed is fed at the time of 5 egg production to provide the nutritional reserve of the flock for egg production.

5, increase the light as soon as possible, with the start of the flock, to gradually increase the light, to the peak of the chicken egg production up to 17 hours is appropriate, morning and evening two ends to make up better, after the start of the light should not be reduced at will.

Generally, before the egg production must be well managed, first of all, we must determine the temperature of the egg production, as well as the humidity, these are very important, may also affect the sales of egg production.

Do a good job of preparing for the transfer to the group before the group is transferred to the basket, carefully check the feeding system, drinking water system, power supply and lighting system, ventilation system, drainage system, cage, cage and other equipment; Complete cleaning and disinfection of the house and equipment.

As the saying goes, "the family is entangled, and the hairy one is not counted", which shows that farmers are afraid of the risks of the breeding industry. With the improvement of the economic level, people's demand for meat, eggs and milk is becoming more and more vigorous, in 2019, pigs will rise sharply, even with eggs, retail in some areas has broken through the 6 yuan mark, many farmers believe that the prospect of laying hen breeding is broad. Now that science and technology are developed, people are breeding more and more standardized, how to manage laying hens before laying eggs?

First of all, scientific feed feeding, do not increase or decrease feed at will. Laying hens must be changed before giving birth after feeding, generally at 18 weeks of age. The main reason for changing the feed is that the production of chickens needs calcium supplementation.

If calcium is supplemented too early, the growing chicken will not have the ability to absorb it, and if the calcium is supplemented too late, it may cause poor egg shell quality. Some farmers are always blindly confident, arbitrarily increase or decrease the feed, which may cause the egg production can not become a scientific curve, affecting the income of farmers, so farmers must adhere to scientific feed feeding.

Second, science increases the duration of light. After entering the laying period, the light time should be extended in the chicken house, and the light time should be gradually increased according to the weight of laying hens at 18 weeks old - 20 weeks old. The light duration is up to 15-16 hours and then remains unchanged.

Some farmers always want to advance the egg laying time, and increase the light time at will, which may affect the egg laying cycle, and the gains outweigh the losses. Therefore, farmers must follow the scientific laws and gradually increase the light time.

Finally, it is crucial to maintain a quiet environment in the coop. It is well known that the harsh noise of chickens, especially laying hens, must be kept quiet in the coop to avoid overreaction. After laying the first two eggs, the hen is extremely excited, and even shows a little nervousness or abnormal behavior, at this time, we must try to keep the chicken house quiet, so as not to disturb the laying cycle.

In order to reduce emergency response, some farmers do not set off firecrackers during the festival.

All in all, the breeding of laying hens must be scientific, now the eggs are quite optimistic, as long as the chicken coop is managed, the economic income is OK.

The breeding and management techniques of chicks are to prepare a large chicken coop, ventilate more, prepare feed, feed them every day, prepare water, and regularly go to injections, so that there will be a lot of eggs during the peak period.

At this time, it is necessary to maintain a certain temperature, the temperature should be kept at about 25 degrees, the diet should also be properly nutritious, add more protein and calcium, and drink more water for yourself, so that the eggs produced are particularly large and will not cause soft eggs.

It is necessary to pay attention to the infection, but also to pay attention to the transfer of chickens, but also to pay attention to vaccination, and to observe the growth environment, and make a reasonable feed match.

When breeding, it is necessary to provide a certain temperature environment to keep it at about 15 24, and at the same time, it is also necessary to add some drugs in the private chat to make it easy to get sick, and you should also do a good job in hygiene management, spray disinfectant more, and ensure that you can be exposed to 10 hours of light every day.

Does the early laying of laying hens have an impact on chickens? Premature onset of production refers to the beginning of laying eggs before the age of the beginning of production, when sexual maturity is advanced and physical maturity is not up to standard. Reasons for early production (1) Some chicken farmers in China profit from egg production, and take inappropriate measures such as increasing light in advance and replacing egg feed in advance to promote early laying of eggs.

2) too many hours of light during the rearing period, and the illumination is too strong, resulting in early production of laying hens. (3) The incubation period is in the period of increasing sunshine from the winter solstice to the summer solstice, and it is easy to start production too early if it is not regulated. 2.

Harm of premature laying (1) Harm to egg production performance: small egg production, light weight, slow increase in egg production rate, short duration of egg production peak, and egg production rate in China after the peak decline. (2) Harm to the chicken body:

Chickens have poor bone and muscle development, small body, light weight, and slow weight gain. Poor health, emaciation, premature aging. It is prone to associative dystocia, increased prolapse, and severe pecking of the anus.

Susceptible to E. coli disease and high mortality rate. 3.Regulatory measures (1) Premature start of production has occurred:

Reduce the number of hours of daylight so that it is less than 16 hours per day. Egg preferent. Chickens with prolapse of the anus, locally**combined with internal drugs**.

Chickens that are pecked by the anus are pecked by many chickens, most of them are seriously injured and have a poor prognosis, so they should be eliminated as soon as possible. (2) If the production does not occur too early, take preventive measures: Chicken farmers do not want to profit from egg production in China, so as not to lose more than they gain.

10 20 weeks old, light maintained for 12 hours a day, illumination 5 10 lux. If the breeding period is from the winter solstice to the summer solstice, it will be adjusted in time according to the changes of chickens.

3. The harm of late production and control measures Late production refers to having reached the age of the first day of production, and the weight has reached the standard, but not starting to lay eggs. Reasons for late production (1) Some chicken farmers are worried about pecking, and use low light for a long time during the breeding period. (2) No measures were taken to gradually increase light during the incubation period.

3) The incubation period was in the time from the summer solstice to the winter solstice, and no control measures were taken. 2.Hazards of late laying (1) Hazards to egg laying performance:

Large eggs are laid as soon as they are laid, double yolk eggs are increased, the peak of egg production is delayed, the number of laying days is reduced, and the total egg production during the laying period is reduced. (2) Harm to the chicken body: due to the large egg production, it is easy to have laborious dystocia and increase the prolapse.

3.Regulatory measures (1) If the start of labor has occurred too late: increase the light so that the daily light is 16-17 hours.

Feed the laying eggs. For prolapsed chickens, it is sufficient to carry out local **. Ovulation No. 2 (egg production promoter) mixed feeding, 10 mg per chicken, shared 2 times, 10 days apart.

2) If the start of production is not too late, take preventive measures: Increase the light at the end of the breeding period as planned. 19 20 weeks old before feeding.
