On May 22, a layer of hens raised by a farmer in Liaozhong District, Shenyang City, Liaoning Province experienced suspected avian flu symptoms, with 11,000 morbidities and 9,000 dead.
On May 24, the Liaoning Provincial Center for Animal Disease Control and Prevention was diagnosed as suspected of the bird flu epidemic.
On May 31, the national bird flu reference laboratory confirmed the epidemic was the H7N9 flu epidemic.
After the outbreak of the epidemic, the local government did a good job in the handling of the epidemic in accordance with the relevant preplans and technical requirements for prevention and control. It had culled 8,000 diseased chickens and the same group of chickens, and conducted harmless treatment of all chickens in the epidemic site. At present, the epidemic has been effectively controlled.
More attention should be paid to the prevention and control of poultry and bird flu during the hot season
The old idea is that only the winter and spring cold season is the high incidence of bird flu, high temperatures in the summer, the virus is not easy to survive and spread in the environment, coupled with well-ventilated poultry houses, the possibility of bird flu is unlikely. Therefore, many farmers often neglect the effective prevention and control of avian flu in poultry during the hot season, coupled with changes in poultry farming methods in recent years (from open, semi-open to fully closed in the past) and frequent variations of bird flu viruses. As well as the decline in flock resistance caused by high temperature and high humidity stress, bird flu in poultry flocks in the high temperature season is often seen and has a tendency to increase in frequency.
To prevent and control poultry and bird flu in the high temperature season, specific measures are as follows:
Strengthen the management of poultry houses, appropriately reduce the stocking density, maintain good ventilation, and do a good job of cooling the wet curtains and cooling the spray, remove the manure from the house, and maintain a good home environment. Closed farms should also be equipped with standby generators to prevent the sudden loss of power to cause a large number of deaths in the flock.
It is forbidden to feed deteriorating and mildewed feed, keep the feed fresh and nutritious, and increase the feed or drinking water by appropriately increasing VC or compound multidimensional drugs that reduce stress and astragalus polysaccharides and improve resistance, so as to protect the health of the flock.
According to immunization procedures and antibody monitoring, real-time immunization and enhancement of H5 and H9 subtype vaccine immunization, it is advisable for the qualified farms to purchase the H5+H7 subtype bivalent bird flu vaccine that has recently been approved for production and marketing in the country, aiming at the current different poultry. Influenza epidemic strains do a good job of immunization prevention.
Strengthen the biosafety measures of poultry farms, strictly prohibit the entry and exit of foreign personnel, especially poultry and egg traffic personnel and vehicles. The entry and exit of personnel in this field shall be strictly sterilized and regularly sanitize and eradicate the surrounding environment and poultry houses within the farm. Insecticide and other work, as far as possible to eliminate the source of infection and cut off the route of transmission.
Once a high-mortality case occurs in a poultry farm, it should be diagnosed as soon as possible, and timely response measures should be taken. If a major epidemic such as highly pathogenic avian influenza is suspected, isolation and disinfection measures should be taken immediately, and immediately go to the local animal health supervision institution or epidemic control center. Reports, before the diagnosis is made, strictly prohibit the listing of dead and dead birds and the random disposal of dead and dead bodies. After the epidemic is diagnosed, the sick and dead birds should be disposed of according to the requirements of the competent business department, and the carcasses and pollutants should be disposed of harmlessly as far as possible. The outbreak of the epidemic is within the scope of the epidemic and the spread and spread of the epidemic will be strictly prevented.
