The epidemic situation of chicken diseases is becoming more and more complex. How to effectively prevent and control the disease needs to be considered from multiple perspectives. The author believes that farmers need to update concepts, change their thinking, and strengthen management on the following four details.
1. Eliminating outliers in time
Regardless of the broiler or laying hens, it is difficult to ensure the degree of development of the individual is consistent between the individual, and sometimes it may be crippled due to surgical diseases. This is inevitable. In the key period of fostering, or an important management season, the group should be adjusted in time to remove individuals with morbidity and poor development from large groups, or to stop feeding out and eliminate losses to a minimum, or otherwise Group, develop more appropriate feeding and management measures. Many farmers believe that adjusting groups does not make much sense and that they are not willing to deal with individuals who are disabled. This concept is very harmful. Dirty individuals are miscellaneous in the normal developing population, resulting in inconsistent uniformity, lack of targeted feeding management, consumption of feed nutrition, increased drug input, and waste of human capital. The most important thing is that the debilitated individuals have poor physique and weak resistance. Under the same husbandry and management conditions, they are more likely to be infected than normal individuals, and once they become ill, they will become the source of infection. Sub-individuals are like “time bombs†buried in chickens. If they are slightly troubled, they may even affect the entire group and even endanger the audience.
2. Correctly consider emergency immunization
Emergency immunization is an emergency preventive measure taken after an epidemic occurs, and it has a good effect in preventing the spread of certain diseases. With regard to emergency immunization, many farmers lack objective understanding and cannot use this method correctly after an outbreak. In fact, emergency immunization can protect the flock threatened by the disease, but there is a certain scope of use, not all vaccines, all diseases are suitable for emergency immunization, the practice has proved that the only reliable vaccine is bird flu vaccine, Newcastle disease vaccine, infectious laryngotracheitis Several kinds of vaccines. Vaccines that are not suitable for emergency immunization cannot be used rashly, otherwise they can only increase unnecessary losses. However, the epidemic that can be prevented through emergency immunization can not usually relax the vigilance. A practical and reliable immunization plan should be formulated to ensure normal immunization. It should be noted that pathogens are likely to have invaded chickens within or immediately after the outbreak of the farm. Emergency immunization at this time will be a great stimulus to chickens during their incubation period. Aggravate the symptoms and speed up the death, but even so, it is worth protecting the entire community. It cannot be used because emergency immunization may aggravate death.
3. Try to forbid veterinarians
The human body is also the carrier of the disease. It can carry pathogens through the skin, hair, clothing fibers, etc., especially after-sales service technicians of veterinarians and veterinary drug companies. They often shuttle between various farms, often contact, dissect sick and dead chickens, and carry pathogens with them. The chances are particularly great that if they do not value their own cleaning and disinfection, they may pose a serious threat to the chicken farm. The after-sales technicians are the representatives of the interests of veterinary drug manufacturers. After a disease occurs in the flock, they only recommend their own products to farmers, making it difficult to fully consider the issue from the perspective of farmers' interests. Therefore, farmers should first pay attention to the disinfection of foreign workers, followed by attention to accumulate experience, learning knowledge, and again is a serious view of professional and technical personnel, after the occurrence of the case, should try to carry the diseased animals to the veterinary clinic to diagnose, need to be a veterinarian Or after-sales service staff home treatment, should also be placed in the isolation zone to the sick chicken, or take the dead chicken off site for necropsy.
4. Insulate and treat sick chickens in time
The diseased individuals in the flock must not be ignored and must be handled with care. Some chickens that seem to have atypical symptoms are likely to be the source of infection for important diseases, such as atypical chicken Newcastle disease, egg production decline syndrome, avian leukemia, etc., are likely to cause large areas of proliferation, causing great harm. Even individuals with common diseases appear to have no direct threat to the population, but they may also be the root cause of the group, because whether it is a surgical injury or an organic lesion of the internal organs, it will reduce the body's resistance and cause Infection with pathogens has become a source of infection. Therefore, the farmer must treat the diseased chicken carefully, observe and treat the disease in a timely manner. After determining the infectious disease, it is necessary to take necessary measures such as chicken disinfection, medication prevention, and emergency immunization. No matter what the nature of the disease or death, Should be buried deeply.
Lishui County, Shandong Province, the second vocational secondary school Wang Daokun
In order to better serve farmers, Gucheng County Bureau of Animal Husbandry established a technical service team consisting of more than 10 key technicians with strong business skills. They went deep into towns and villages to hold training courses to publicize the breeding policy. Send technical data, on-site demonstration guidance, and promote new technologies.
Safe chickens need to update 4 concepts
Recently, a letter from Guo Xinfa from Daxinzhuang Township, Wei County, Handan City, said that chickens have been started in May. For some reason, chickens have died every day. Although some treatment measures have been taken, the effect is poor. To this end, we specifically publish this article in the hope that the chicken farmers firmly establish the "prevention and treatment of" culture principles, update concepts, strengthen management, reduce the incidence, and ultimately improve the comprehensive breeding efficiency. ---editor
