Diseases often occur in spring, what are the precautions and preventive measures for raising chickens?

With the arrival of spring, the temperature rises, bacteria and viruses also begin to grow and reproduce, so diseases are easy to occur in spring. It is necessary for farmers to do a good job of prevention in advance, so what are the precautions and preventive measures for raising chickens?

Note:

1. Maintain a suitable temperature. There is a large temperature difference between day and night in early spring, so special attention should be paid to night temperature management. The chicken house should be closed, and the temperature in the house should be controlled at 16 ℃ ~ 26 ℃. When heating up with coal stove, attention should be paid to prevent chicken gas poisoning.

2. Correctly dealing with the relationship between heat preservation and ventilation if we emphasize the heat preservation of the chicken house and ignore the ventilation and ventilation, it will easily lead to the dirty air in the house and the breeding of a large number of bacteria. Chickens often have a high incidence of colibacillosis and chronic respiratory diseases when they inhale harmful gases such as carbon dioxide and ammonia for a long time and grow in an environment where bacteria breed.

3. To improve the nutrition level of feed in this season, the climate is changeable, and the resistance of chickens is relatively weak. therefore, it is very important to improve the nutrition level of feed. The protein content in the chicken feed should be increased by 3% to 5%, the energy in the feed during the breeding period should be increased appropriately, and the feeding amount should be increased appropriately to resist the cold.

4. supplementary light in early spring, night is long and day is short, lack of light will lead to the decrease of laying rate of laying hens. In order to overcome this natural defect, artificial supplementary light can be used to make up for it. Under normal circumstances, the total light time per day should not be less than 14 hours, nor more than 17 hours. The supplementary artificial light intensity should be 2: 4 watts per square meter of chicken house area.

5. Stress-reducing chickens are timid, easy to be frightened, and very sensitive to changes in the external environment. Therefore, feeding, adding water, picking up eggs, disinfection, cleaning, cleaning feces and so on must have a certain time and order. Act gently at work, and strangers and other animals are strictly prohibited from entering the henhouse. If there is a strong sound in the outside world, such as the sound of firecrackers during the festival, the shrill sound of gongs and drums, and the whistling sound of the north wind, the breeder should enter the chicken house in time to create a safe atmosphere in which the master is around. Appropriate amount of multivitamins or other anti-stress drugs can also be added to chicken feed or drinking water to prevent and reduce the loss caused by stress reaction.

6. To do a good job in hygiene, it is necessary to do a good job in the environmental hygiene inside and outside the chicken house and disinfect it regularly.

Precautionary measures:

1. Prevention of diseases

All kinds of diseases of chicken can occur in every season, but spring is the season of mass reproduction of microorganisms, mosquitoes and flies and other insects also begin to breed, which is the season of high incidence of bacterial diseases and parasitic diseases. in addition, the climate characteristics such as dry weather, windy sand and large temperature difference between day and night in spring promote the occurrence of various respiratory diseases, so chicken breeding in spring should pay attention to the prevention of respiratory, intestinal and parasitic diseases.

2. Temperature and humidity protection

Suitable temperature and humidity is the key to the growth of chickens. The ambient temperature in the chicken house is generally 18-22 ℃. The temperature is higher during the day and lower at night in spring. But in the process of breeding, the temperature difference between day and night should be controlled at 5 ℃, and the humidity is generally about 50% and 70%. Higher or lower than the suitable humidity is not conducive to the growth of chickens. Therefore, it is necessary to do a good job in temperature and humidity control measures.

3. Prevention and ventilation

The core of the ventilation management of the chicken house is to meet the respiratory volume of the chicken flock, adjust the temperature and humidity of the chicken house and remove the residue of harmful gases in the chicken house. In spring, the ventilation of the chicken house should at least meet the minimum breathing capacity of the flock, that is, 0.4 cubic meters per kilogram of body weight per chicken; if conditions permit, it is best to achieve the appropriate ventilation rate, that is, 1.2 cubic meters per kilogram of body weight per chicken. Keep the air quality in the henhouse good.

4. Anti-nutrition

Under the most suitable conditions such as temperature and humidity, humidity, ventilation and illuminance, it is the most suitable period for chicken production, and the various functions are growing at a high speed. At this time, it is necessary to appropriately improve the nutritional level of the diet to meet the nutritional needs of chickens and promote their suitable growth.
