How to strengthen the nutritional management of laying hens and the feeding management of laying hen

You can consult the problem of raising chickens on the breeding software - Somutong.

1. Temperature control.

For the laying hens raised by farmers, the most suitable temperature environment for its survival is 8 -28. The temperature is too high or too low will affect the egg production efficiency of chickens, and scientific research has found that every time the environment in which the laying hens live rises or decreases a temperature, it will cause the egg production of chickens to decline. Therefore, farmers want to raise good laying hens, to keep the temperature of the chicken coop stable within the comfortable environment range all year round, to avoid because of the four seasons in our country, the temperature difference changes too much, which has an impact on the growth and development of chickens, thereby affecting the egg production rate of chickens.

2. Medication for disease prevention.

Farmers want to raise high-yielding laying hens, in the epidemic prevention work can not be sloppy, farmers should regularly carry out virus antibody testing in the flock, to avoid the phenomenon of a large number of virus infections caused by the failure of antibodies, and always pay attention to the immune level of the flock, can not blindly vaccinate the flock, and can not increase or reduce the use of vaccine in the flock. Once the chicken is infected, it is necessary to control the condition of the flock in time, and try to choose more sensitive drugs to control the disease.

3. Scientific ingredients.

For chickens, different seasons should be improved according to the different nutritional needs of the chickens, in the spring and winter, the temperature is relatively low, farmers should appropriately add some high-fat and high-energy nutrients to the chickens, in order to ensure that the chickens effectively spend the low temperature season. Farmers can not use the way of free allocation of feed, in the proportion of feed, not only add more corn to the feed. Because there is no ratio of a variety of raw materials, it may cause the content of protein, vitamins, minerals and other components to be in short supply, which will lead to the appearance of chicken flock egg production performance is reduced, the eggshell is soft, the eggshell is thin, and even leads to the chicken flock does not exist at all The peak period of egg production, so when the farmers change the feed, we must use the scientific feed ratio, can not be added blindly.

4. Timely light.

Light is a very important factor for the growth of laying hens, especially for promoting the sexual maturity of the flock plays a decisive role, so farmers must give the right light to the chickens, requiring the chicken to maintain 18 hours of light per day during the laying period, the most suitable light intensity is 5lx, especially in the winter or foggy season, must be turned on in time to light, can not let the dim hinder the development of chicken egg production.

In the hot season, the feed intake of chickens is relatively reduced, in order to maintain the high egg production level of summer chickens, it is necessary to provide sufficient nutrients, the protein and energy levels in the diet should be appropriately increased, and the proportion of raw materials in the feed should be adjusted, such as increasing the proportion of fishmeal 1 3, to improve palatability and digestion and absorption, and calcium feed should also be added. Because chickens drink a lot of water, excretion increases, and salt should be appropriately increased, which can effectively prevent and control pecking. Add anti-stress medications.

Add anti-stress drugs to the diet in an appropriate amount to improve the immunity of chickens and enhance the body's ability to cope with stress. For example, adding 0 04 vitamin C to the summer diet can inhibit the rise of chicken body temperature, increase feed intake, and enhance resistance; In summer, the temperature is high, the chicken's breathing is accelerated, the content of HCO3 in the blood is reduced, the pH value is increased, and alkalosis is easy to occur. Implement morning and evening feeding.

In summer, the temperature is higher at noon, and the temperature of the chickens also rises, and the chickens are less interested in eating, or even refuse to eat. Therefore, it is necessary to feed in the early morning and evening when the weather is cool to increase feed intake, and it is best to feed once at night to ensure adequate nutrient intake. In summer, the temperature is high and the humidity is high, so it is necessary to strengthen the storage and management of feed to prevent feed mildew and rancidity.

Feed with green fodder. Summer is the fast growing season of green and juicy feed such as forage and green vegetables, with many varieties and high yield, and can be directly fed with chopped fresh green feed at noon in the high temperature season. Pay attention to control the amount of chicken feeding, not more than 50g per day, to prevent chicken diarrhea.

After the large production of eggs in spring and summer, there is a moulting and trimming stage in autumn. The time of natural moulting of chickens is uneven according to the front and back, and the early moulting is earlier in repair; Layers with late moulting have thinner eggshells in the later stages, reduced egg weight, and reduced fertilization and hatchability. Due to the consumption of feed during this period and the increase in feeding costs, many people adopt the method of restricting feeding, water and light to manually force moulting.

This method is adopted, firstly, the physical foundation of chickens is damaged; Second, it takes a long time, and the laying hens can resume egg production in about 50 days.

The specific method is: add 2% zinc to the chicken diet, after feeding for 3 days, the gut production of the laying hen decreases by 50%, and its feathers 1 3 fall off. Feeding for about 9 days, basically all stop laying eggs, 80% of the feathers fall off, stop adding zinc to the diet on the 12th day, at this time the feathers are basically replaced, new feathers have sprouted one after another, egg production has begun to recover, about 20 days or so its egg production can return to normal.

This method is simple and easy to implement and allows the hens to moult quickly and without adverse effects on the flock.
