How to do a good job in the autumn management of laying hens

If possible, it is best to formulate scientific immunization based on the results of antibody tests. Appropriate multi-vitamin supplementation to improve disease resistance. Prevention of fallopian tube inflammation and other diseases, timely removal of "fake hens" and discontinued hens.

In order to improve egg quality, control feeding costs and reduce the feed to egg ratio. The amount of feeding should be sufficient, maintain a relative temperature, and ensure drinking water**; Maintain a suitable temperature in the house and keep the light hours at 16 hours a day; Minimize the occurrence of various stresses, any stress at this stage will cause a decrease in egg production rate.

<> first of all, the light time should be sufficient, and the chicken coop should be disinfected in an emergency, cleaned, and cleaned up the manure frequently. The above has also been said, the laying hens in the general farm egg production years in 16 months, generally 16 months after the laying hens egg production has been very low, in order to improve the efficiency of the farm, these egg production decline laying hens are generally eliminated.

The actual daily nutrient intake of a layer is determined by the composition of the diet (feed formulation) and the level of feed intake (feed intake). Unfortunately, 18-week-old and 25-week-old hens have limited feed intake and may not be able to meet their nutrient and energy needs, resulting in a deficiency. Control environmental sanitation and take disinfection measures (3-4 times a week in spring and autumn, 1 day in summer, and 2 times a week in winter).

Control the ambient temperature (15-25 degrees is optimal) and humidity (45-70%), and pay close attention to the feed intake, mental condition, feces changes, egg changes, etc.

After the peak period of egg production, it is necessary to see how the market chooses how to manage, the profit is large, the intake of calcium should be increased for laying hens, and the corresponding reduction of protein, the egg shell will become thinner after the peak period of egg production, so it is necessary to consume more calcium. Improves egg production rates; Reduce the rate of dead tao; Reduce the breakage rate of eggs; Reduce feed waste and increase feed compensation. Lack of calcium or imbalance of calcium and phosphorus in feed formulation:

The composition of the eggshell is calcium carbonate, which is an eggshell formed by the calcium material in the reproductive system of the chicken, and if there is a lack of calcium in the body or an imbalance of calcium and phosphorus, the eggshell will be of low quality.

Add some nutritious food to them, let them absorb nutrients, disinfect and clean them regularly, create a good environment for them, give them some anti-disease medicines, let them recuperate their bodies, and I believe they will give birth soon.

It is necessary to ensure that the hen drinks water normally every day**, and the temperature of the hen's laying environment must be maintained, the temperature must be high, and the light must be maintained for at least 16 hours.

After the peak period of laying hens, it is necessary to give the hens a reasonable temperature living environment, and if you want to increase the care time, you should also give adequate feed nutrition

You can reduce the feed appropriately, you can put some dry wood and sprinkle some water on it, and finally there are some termites on it, which is a good food for chickens.

It is still necessary to increase the temperature, and also add some light in the chicken shed, so that the hens will lay more eggs, and the income is still very good.

1. Humidification and cooling The temperature and humidity of the laying hen house is a necessary indicator to promote egg production, the relative humidity reaches about 55%, and the temperature reaches about 25, which is the best environment for egg production. When the temperature reaches 28 or more, it is necessary to pay attention to the reaction of the chickens, especially at noon direct sunlight, the temperature of the chicken house often reaches about 32, with the increase of heat and the evaporation of water, the humidity will continue to drop, and it is easy to occur sharply dry heat. In addition to opening the windows properly, it is necessary to increase ventilation, in addition, you can hang curtains and add water to cool down, circulate tap water to cool down, hang sunshade nets on the windows to cool down, or install electric fans at the same time.

2. Adjust the feed nutrient level In the high temperature season, feed intake decreases, and insufficient protein intake will directly affect egg production. Experiments have proved that a low-protein diet with a balance of methionine and lysine is more valuable than a diet with a high total protein level, and the method of increasing protein can be adopted, adjusting the formula, increasing the use of methionine and lysine, or increasing the amount of soybean cake by 2-3%, or increasing the amount of fishmeal by 2-4%, so as to achieve the goal of eating less and better. According to the reduction of feed intake of chickens, the proportion of calcium and phosphorus in the feed should be appropriately adjusted, generally increasing by 5-10%; At the same time, 1-3% vegetable oil is added to increase energy levels; The content of vitamin E, vitamin C, vitamin K, biotin and riboflavin in the diet should also be increased accordingly.

It is best to measure the feed intake of the chickens regularly and adjust the nutrient level of the diet according to the actual feed intake to meet the needs of the laying hen production. 3. Strengthen feeding management and reduce density, 4 white-shell chickens per cage and 3 brown-shell chickens per cage; Sufficient drinking water, the growth of chickens is inseparable from water, laying hens need 42-45 grams of water for every 60 grams of eggs, every gram of feed ingested, 2-3 grams of water are needed, therefore, the suitable environment for laying hens need to supply 2-3 times the water of feed, and in the hot summer, it is necessary to supply 3-5 times the water, preferably clean and cool water; Choose cool morning and evening feedings; Strengthen ventilation, high temperature in summer, fast microbial reproduction, fast evaporation of water, fast metabolism in chickens, feces produce ammonia and CO2 fast, therefore, we should pay attention to the supply and circulation of oxygen in the air, laying hens for a long time lack of oxygen or fresh air will affect egg production; Remove chicken manure frequently, the manure of laying hens is thin in summer, the humidity is high, and the chicken manure is easy to ferment to produce ammonia, hydrogen sulfide and other harmful gases or other peculiar smells, which is easy to induce respiratory diseases. Therefore, the feces and bedding in the house should be cleaned in time (at least once every other day) to prevent pollution and keep the house clean, dry and hygienic.

4. Do a good job in the prevention of chicken diseases Due to the influence of many factors in the hot summer, chickens are susceptible to diseases, so it is necessary to do a good job of routine immunization work to prevent the occurrence of diseases. 5. The weather is hot in summer, pay attention to the cleaning of the waterline, it is easy to breed biofilm in the waterline of the chicken farm, pay attention to waterborne diseases, do not worry about cleaning the waterline regularly, or take the chicken to drink 4-5 days a week!

(1) The body is still developing after the start of labor. Hens that have just entered the laying period, although they are sexually mature, but their bodies are still developing, and their weight continues to grow, 24 weeks after the start of laying, and their growth and development basically stop after reaching about 54 weeks of age, and their weight gain is less, and most of them are fat accumulation after 54 weeks of age.

2) Laying hens are neurotic and very sensitive to environmental changes. During the laying of eggs, the change of feed formula, the change of feeding equipment, the change of environmental temperature, humidity, ventilation, light, density, the change of feeding personnel and daily management procedures, etc., and the stress factors such as chicken disease and vaccination will have an adverse impact on egg production.

3) The utilization rate of nutrients is different in different periods. At the beginning of sexual maturity, the ability of the hen's body to store calcium is significantly enhanced. With the beginning of production to the peak of egg production, the chicken's ability to digest and absorb nutrients is enhanced, and feed intake continues to increase.

In the late stage of egg laying, its digestion and absorption capacity is weakened and the fat deposition ability is enhanced.

At the beginning of the laying, the egg production rate rises rapidly, and the egg weight gradually increases, at this time, if the feed intake cannot keep up with the nutritional needs of the eggs, then the nutrients stored in the body at the end of the breeding period are forced to use, and the result is slow weight gain, so that the resistance is reduced, and the egg production is unstable. If the cold snap hits in the cold season, the insulation conditions of the chicken coop are not good, and the egg production rate often decreases with the cold snap, which will affect the egg production performance in the later stage.

This watch out for the disease of the season. Only those chickens are healthy.

In the case of scale and non-production cost limitations, the economic benefits of layer production mainly depend on the level of production management and the market operating environment. Due to the difficulty of the operability of the market operating environment, the level of production management has become an important factor in determining the size of its economic benefits. It is of great significance to improve economic efficiency to formulate production management methods that are practical and constantly revised and improved in production practice.

1) Standardize the technical operation procedures The technical operation procedures of the chicken farm are the technical specifications for the daily operations formulated in accordance with scientific principles in its production. The technical measures and operations in the incubation management of chickens and breeders are implemented through technical operating procedures, and they are also the basis for inspection and production. The work of the flock or hatchery at different stages of rearing requires different technical operating procedures according to its production cycle.

For example, brooding (or rearing chickens, or laying hens) technical operating procedures, incubation operating procedures, etc., usually include the following contents: put forward production indicators for the task, so that breeders and staff have clear goals; The characteristics of the flock and the key points of feeding management at different feeding stages were pointed out. The technical requirements of different breeds of chickens and incubation conditions are listed in sections according to different operation contents, and practical requirements are proposed; It is necessary to use advanced technology as much as possible and reflect the successful experience of the field, and the provisions should be concise and concrete. The regulations should be discussed by the personnel concerned and made necessary revisions in light of the actual situation.

Only when the direct production personnel think that it is feasible, the technical operations can be implemented, and the technical operation procedures formulated can have real value.

2) reasonable arrangement of daily work procedures Breeders, hatchers according to their work characteristics, especially the physiological needs of laying hens, set up a daily "one-day work program" that can meet the production requirements to the greatest extent, which is convenient for technical personnel to check, and is conducive to the reasonable arrangement of work by production personnel. See Table 7-3 for details.

Table 7-3 Daily working procedures for caged chickens (examples).

Table 7-3 Daily work procedures for caged chickens (example) (continued)-1

Table 7-3 Daily work procedures for caged chickens (example) (continued)-2

3) Strictly implement the chicken farm management system Chicken farms should formulate corresponding management systems according to the work characteristics of different departments, the most important of which is the health and epidemic prevention system, see Table 7-4 and Table 7-5.

Table 7-4 Sanitation and epidemic prevention system of chicken farms.

Table 7-5 Chicken house sanitation and epidemic prevention system.

Table 7-5 Chicken coop hygiene and epidemic prevention system (continued)-1

First, what is the purpose of adjusting and controlling the nutritional mix of newly opened laying hens.

Start laying hens. For some newbies or veterans, it may not be clear. And our farmers want to adjust the nutritional mix, that is, to control the egg production rate of new laying hens.

It is not only to promote the development and maturity of all aspects of new laying hens, but also to prepare for the breeding and production of improved breeders in the coming year, and also to improve the egg production of chicken farms.

Increases egg production.

2. What is the nutritional supply before the start of production?

For laying hens before the start of production, it is necessary to provide sufficient nutrition to ensure the stable egg production of laying hens. Therefore, before laying eggs, the laying hens need to be provided with high-quality full-price diets, so as to meet the urgent needs of the new laying hens for protein, metabolic energy and calcium.

For the different egg production rates of laying hens, there are also different requirements for nutritional matching. Please take a look at the table below:

For the flock during the laying period, the protein content should be between 16 percent and 16.5 percent, and the energy metabolized by the feed should be between 2700 and 2750 kcal.

Corn. After winter, when the egg production rate reaches 50%, the protein content and metabolic energy should be reasonably adjusted.

For friends who raise chickens in winter, they should do a good job of keeping the chickens warm. At the same time, chickens need more calories because of the cold, so they should be fed hot feed and warm water frequently. And it can be appropriately added to the drinking water feed of the chickens, increase their appetite and water intake, and prepare for the improvement of the egg production of the chickens.

Salt. And the chickens in this period, due to weak resistance, should do a good job in the health management and epidemic prevention of laying hens, and try to avoid inoculation and deworming.

All in all, for qualified chicken farmers, they should buy high-quality feed from high-quality and trustworthy businesses, do a good job in the early management of laying hens, and prepare for the egg production rate, which can also improve the economic benefits of farmers and make a fortune.
