Introduction: Although there has been an outbreak of avian influenza in China, a complete set of epidemic prevention, quarantine and quality monitoring system has been established by the leading backbone enterprises of the poultry industry in China from the source of breeding to the processing of products to the storage, transportation and sales The four lines of defense established have effectively prevented the invasion of avian influenza So far, there has been no outbreak of avian influenza in the leading enterprises, backbone enterprises and their contracted feeders, Therefore, leading enterprises Although there has been an outbreak of avian influenza in China, a complete set of epidemic prevention, quarantine and quality monitoring system has been established by the leading backbone enterprises of the poultry industry in China from the source of breeding to the processing of products to the storage, transportation and sales The four lines of defense established have effectively prevented the invasion of avian influenza So far, there has been no outbreak of avian influenza in the leading enterprises, backbone enterprises and their contracted feeders, Therefore, the leading backbone enterprises ensure the safety of poultry products SVt Leading backbone enterprises invest millions of yuan in epidemic prevention and disease prevention every year, equipped with advanced detection and analysis instruments, trained technical personnel operate in strict accordance with the standardization, and take comprehensive epidemic prevention and quarantine measures of four lines of defense The first line of defense is that chickens entering the field must pass the inspection, and foreign personnel and vehicles are not allowed to enter the field, and all kinds of devices entering the field Equipment and articles shall be strictly disinfected and provided with special channels An epidemic prevention center shall be set up outside the poultry yard The incineration workshop shall burn all the external packaging used for vaccine drugs entering the yard, and all the wastes of sick, weak, disabled, dead chickens or incubation plants, so as to isolate the poultry farm from the outside world The second line of defense is to set up automatic disinfection pump on the gate to spray and disinfect all vehicles entering and leaving the field, and disinfect the pool to disinfect the wheels and staff boots Burn all chicken feathers and sundries with a flame thrower every day, clean them once a week, and brush the roads and walls of the site with lime water powder every month The second is to regularly disinfect chicken flocks with low toxic and non irritant disinfectants to prevent the invasion of various bacteria and viruses The third is to soak and disinfect all kinds of utensils and articles with high efficiency and low toxicity organic chlorine preparation Fourth, when the henhouse is empty and waiting for the next batch to be raised, thorough fumigation and disinfection should be carried out in the house The third line of defense is to develop a detailed immune plan, vaccinate the chickens regularly, constantly detect the antibody level and adjust it at any time, so as to improve the ability of the chickens to prevent related diseases The fourth line of defense is to adopt the intensive and high-density feeding mode which is conducive to the overall epidemic prevention, and to enhance the nutrition of chicken groups to improve their disease resistance ability by strengthening the protein and energy level of chicken, increasing the vitamin content in the diet, improving the physical and chemical characteristics of the diet to maintain the ecological balance of chicken intestines The four lines of defense and perfect management measures ensure that the backbone enterprises can produce healthy and safe poultry SVT in addition, the quality, hygiene and safety of Sanhuang chickens produced in 235 registered breeding places for live chickens in Hong Kong and Macao are also guaranteed, and consumers can eat them at ease It is understood that the registration sites of Hong Kong and Macao live chicken branch in China are generally located in areas with sufficient air circulation and light, far away from urban areas, plant areas, residential areas, commercial areas, mixed bird areas, waterfowl areas and forest areas (less flying birds) Many registration sites have also built a number of garden style chicken farms without pollution, odor, epidemic situation and infectious media, which are all under closed management The vehicles and business personnel leaving the site shall be strictly disinfected, and non-governmental departments and monitoring personnel shall not enter into the chicken farm, and employees of all processes and posts in the farm shall not directly contact with each other The registration farm also implements strict management system and post responsibility system from breeding, seedling incubation, commercial chicken feed formula, feeding, drug injection, epidemic prevention, chicken fence specification, disinfection and other aspects Under the direct guidance of professionals, it has formed a set of scientific feeding methods representing the highest level of yellow chicken breeding in China and even in Asia The color, appearance, nutritional value, drug residue, anti epidemic ability and other aspects of chickens have reached or exceeded international standards, and have been fully affirmed and highly evaluated by the World Health Organization In 2003, the inspection and quarantine department also comprehensively implemented the "2211" mode of two accreditation, two monitoring, one network and one core, and carried out the "2211" mode for vaccines, feed, immunization, drugs Inspection, export supervision, implementation of the whole process of monitoring, together with the final monitoring of Hong Kong and Macao, special vehicles, special personnel, special line shipment of live chickens into Hong Kong, must go through seven gates In addition, since August 2003, all the live chicken registration sites for Hong Kong and Macao have been vaccinated In terms of drug varieties, dosage, injection time and other aspects, they operate in strict accordance with the requirements of the inspection and quarantine department and
