Do you want to know the causes, prevention and treatment of chicken respiratory diseases?

I    Analyze the factors that cause chicken respiratory disease infection:

2. The  psychological effect of the  breeder: the chickens are afraid that the chickens will  be cold and frozen, and they  pay attention to heat preservation without ventilation, causing the chickens to move in an environment with insufficient oxygen and high concentrations of ammonia, carbon dioxide and other gases. Some pathogenic microorganisms can easily invade the body and cause the disease of the chicken flock, and poor ventilation for a long time will cause the chicken to be hypoxic, and the autonomic function of the heart and lungs will decline, causing the body to be in a potential pathological state, and there will be some immune responses to the body after immunization big impact.

3. The  etiology  is  not  clear:  Sometimes  we  usually  assume  that  respiratory  diseases  caused  by  ventilation  are  caused  by ventilation, but this is not the case. Generally, there is no wind for 2-3 days before the weather gets warmer or the weather is sunny. At this time, if the chicken house is not ventilated and the air circulation inside and outside is not smooth, the harmful gas in the chicken house will accumulate more and more, and the pathogenic  microorganisms will  It is particularly easy to sneak  into  the  chicken  body,  thus forming  an  incubation  period  for  the  chicken to  become  ill.  Therefore,  when  we  raise chickens, we must follow the principle of "ventilate if there is no wind, and shelter from the wind if there is wind", and do a good job of ventilation at all times

4. The temperature difference between day and night is too large: Some farmers place their thermometers unreasonably, and only pay attention to the average temperature. They feel that the temperature difference between dayand night is not large.This factor makes the respiratory tract often undetectable? Therefore, more consideration should be given to the ventilation  speed of the chicken house during the day and night. The temperature and humidity of each position of the chicken house, etc.

5. Physiological characteristics and structure of chickens: it is easy to cause respiratory diseases, and the air sac is a unique  physiological mechanism of chickens. The air sac communicates with the outside world, and the air sac is distributed around  the internal organs of the body, filling around major internal organs such as the heart and liver. Under this unique physiological  structure, it is necessary to pay attention to the disinfection and cleaning of the environmental sanitation of the chicken house. For the  large-scale  and  intensive  chicken breeding  mode,  the  poor  air  quality  in  the  chicken  house  directly  reduces  the  vibration  frequency  of  the  respiratory  fluff, destroys  the  integrity  of  the  chicken  respiratory  mucosa,  and  causes  a  large  number of pathogenic microorganisms to enter the body and invade the air sacs and other parts to hide .

6. The poor environment of the chicken house in the chicken farm promotes the repeated occurrence of respiratory diseases:  due to the unique air bag structure of the chicken body, the requirements for environmental sanitation are very high. However, in actual production, many farmers have ignored the physiological characteristics of the respiratory systemof chickens, and  have not created better conditions for the living environment of chickens.

How to prevent respiratory diseases in chickens?

Main measures:

Do a good job of ventilation and start from the source: the windows of semi-open or open chicken houses should be designedon the front and rear walls, the front windows should be wider and larger, and they can be lower from the ground to facilitatelighting. The ratio of the window to the ground area is 1:8-10 is the best. The rear window can be smaller, about 2/3 of thearea of the front window, but be careful not to blow the air into and out of the front and rear windows directly to the chickensYou can install a PC pipe on the roof of thel house as a blower or install a finished ventilation cap . lt can not only effectivelyensure the air quality of the chicken house, but also facilitate the control of the temperature of the chicken house.

1. lnoculation and immunization of chicklings Select breeding eggs without disease infection to incubate chicklings to ensure the health of chicklings. At the same time, the purchased chicks should be immunized against infectious bursa, infectious bronchitis, infectious laryngotracheitis and infectious rhinitis to prevent the invasion of pathogens such as mycoplasma, whichis also the key to preventing chronic respiratory diseases.
2. Strengthen feeding and management Respiratory diseases of chickens occur frequently in winter and spring, because the weather is cold at this time, so feeding and management must be vigorously strengthened. first of all, do a good job of Keeping warm and cold, and pay attention to ventilation. In winter and spring, insulation and heating facilities must be added supplemented by appropriate ventilation to meet the temperature of the chickens and the freshness of the air.
3. Reduce stress factors Stress is an important factor in inducing chronic respiratory diseases. These stress factors mainly include physiological stress (such as lack of adrenal cortex hormone secretion), environmental stress (such as high temperature, cold, noise, ventilation, etc., Management stress (density, capture, transportation, etc., hygiene stress (such as vaccination, medication, etc.), should minimize the occurrence of these factors. And using vitamins to relieve this symptomsuch as :Multivitamin soluble powder + Astragalus Polysaccharide powder
