Cold is a common and frequently-occurring disease, and its pathogen lives in the respiratory tract of ducks, so ducks can occur anytime and anywhere. Duck colds can be divided into common colds and influenza.
this disease is the number one disease affecting our aquaculture industry. There are predisposing factors for the occurrence of common cold. As long as the inducing factors are well controlled, it is difficult to catch a cold.
1. The "feng shui" of duck shed is not good. Bad feng shui in duck shed refers to disharmony of cold, humidity and temperature in duck shed, which often leads to the occurrence of duck common cold. In addition, the construction of duck sheds in influenza epidemic areas is the main cause of duck influenza.
The migration route of migratory birds along the coast, where beaches and water sources are mixed; Inland forests and canals are places where birds gather; Intensive breeding, mixed breeding of large and small, mixed breeding of ducks and geese, and dirty and dirty communities often become the focus of influenza. The shed built in the epidemic focus will become the epidemic focus first.
2. Weather change is the most important natural inducing factor. Natural inducing factors can occur all year round. Climate change in four seasons, such as wet in winter and sultry in summer, leads to the decline of duck resistance; Alternating temperature difference between day and night every day; Sudden weather changes, such as wind, rain, lightning, cold and summer, snow and humidity, are all serious inducing factors.
It is especially popular in the season when the temperature changes greatly in winter and spring from November to March of the following year. Summer also happens occasionally after heavy rain.
3. Feeding management errors are the most common inducing factors. Turn to the group without heating; Suddenly stop heating; Suddenly open the big tuyere for ventilation; Direct-blown ducks in ventilation; Stuffy shed, stuffy duck, high humidity, suddenly open the film for ventilation after stuffy duck; The density is too high.
Management mistakes such as expanding the group too early and too late are the most common mistakes in duck farms at present. It is a common human factor that causes ducks to catch cold.
4. Key concepts of cold prevention and control. Fine management, sufficient oxygen and clean environment are the "golden three principles" to prevent colds. Influenza virus will be killed in direct sunlight for 4 hours, and it is easy to get sick if there is insufficient oxygen in cloudy and foggy days.
The survival time of virus particles outside ducks is generally 5 minutes to 2 days, but the virus hidden in pollutants in the environment can survive for 3 months, so cleaning and disinfection are important prevention and control measures to maintain environmental hygiene.
Fine feeding management, reducing inducing factors, and improving and maintaining the normal resistance of ducks are the highest principles for ducks to avoid catching cold.
In autumn and winter, use Xinmujing Fangbaidu Powder to prevent viruses, colds, influenza and flavivirus.
jingfangbaidu powder is a pure Chinese medicine, which can resist viruses and improve resistance, and mainly prevent wind-cold colds and various viral diseases.
A cold is the root of all diseases. If you don't catch a cold, there will be no other diseases!
