I. Status of broiler breeding in China The broiler industry is the fastest-growing industry in China's animal husbandry since the reform and opening up. According to statistics, in 2001 China's poultry meat production reached 12.73 million tons, ranking second in the world. Broiler rearing capacity reached 2.4 billion and chicken meat production 12 million tons. According to relevant data, in 2001, a total of 645,000 sets of ancestral breeders were introduced. Two million sets of parent breeding chickens were introduced, of which 360,000 chickens were introduced into the AA ancestors, which provided sufficient germplasm resources for the development of the broiler industry. However, although China is a big producer of chicken meat, and exports are less than 3%, the key to its problems lies in disease control, drug residues, and environmental issues. After the addition of the WTO, the tariff barriers of various countries have been broken down and replaced by green barriers and technical barriers, thus creating tremendous pressure and resistance for China's broiler industry. In addition, no matter whether it is scattered farming or large-scale farming, large amounts of waste such as manure and dead scouring chickens cause huge pollution to the environment. This is also a major environmental problem that cannot be ignored after the rapid development of China's broiler industry. 2. Analysis of the significance and prospects of public harmless broiler breeding For more than 10 years, the production of pollution-free vegetables and fruits in China has reached a considerable scale, and great achievements have been made in foreign exchange earned through exports. Unpolluted livestock and poultry products have been repeatedly World trade barriers fell. As a large-scale poultry country, implementing pollution-free farming has great significance. Non-pollution breeding of broilers will surely play a positive role in promoting the development of agricultural science and technology. China's annual output of poultry meat is the world's leading, but exports are few, and green security is a "bottleneck." After the implementation of pollution-free aquaculture production, this situation will surely be reversed, which will help China's broiler products enter the international market to participate in competition, especially in Southeast Asia and Japan and South Korea markets and African markets, thus striving for foreign exchange, and build an excellent brand of Chinese broiler products. The realization of pollution-free aquaculture production and industrialization operation will enable the industry to specialize in the internal raw material varieties, scale feeding, standardization of production processes, novelty of packaging, integration of management and operation, and scientific marketing means to promote the broiler industry from the pursuit of “cheap†The shift from “type†to “high quality†and from “quantity energy consumption type†to “green safety type†has immeasurable significance for stimulating the sustainable development of the whole industry and even animal husbandry. In addition, to adjust China's rural industrial structure, Stabilizing the countryside, increasing agricultural efficiency, increasing farmers' income, and improving the ecological environment will have far-reaching impacts. At the same time, we will smoothly connect the small farmers who are helping thousands of households to reach the market, and realize the tens of thousands of households and the ever-changing “big marketâ€. , It will also have a great role in promoting.. 3. Countermeasures and recommendations for pollution-free broiler breeding (A) Veterinary broiler breeding should be fully implemented veterinary bio-security system 1. Barrier blocking and pathogen inactivation technology. Through scientific site selection, far away Traffic roads and residential areas, no industrial pollution in the surrounding 3 km, digging the epidemic prevention ditch outside the farm, set up at the gate of the chicken farm Disinfection pools, chicken coops, roads and equipment are often sterilized 2. Immunization engineering and poultry disease control techniques, combined with the epidemiological characteristics of the region to develop reliable immunization procedures, while strengthening management, prevention, reducing disease occurrence, and epidemic prevention The treatment complies with NY5036-2001 guidelines for veterinary epidemic prevention in broiler breeding and NY5035 2001 Guidelines for the use of veterinary drugs in broilers. 3. Harmless disposal of medicines and environmental quality control techniques. Innocuity of feces, sewage, dead scouring chickens, etc. produced in chicken farms. Disposal, in line with GBl 6548. Wastewater is treated with high-level, low-infiltration and fungicides, wastes such as excrement are fermented, and deodorizers and fertiliser conditioners are added to make granular organic fertilizers as special fertilizers for fruits and vegetables. Large-scale greening improves regulation, and the air quality complies with GB3095: Water is in line with NY5027 2001 Pollution-free food and livestock water standards; 4. Animal welfare technology is improved. In the 21st century, humans began to pay attention to animal care. Western developed countries have successively formulated “animalsâ€. The Protection Act and the Animal Welfare Act are both for the environment of animal oysters and for the death of animals. Detailed regulations: For broilers, due to the short growth cycle and high feed conversion, active animal welfare measures should be taken, such as providing good ventilation, temperature, humidity, and light; providing adequate feed and drinking capacity Adequate intake of drinking water in the location, as little as possible medication, no drugs; to provide adequate nutritional needs and energy needs, reduce drug residues, make it healthy growth 5. Scientific feeding methods and program management techniques. Most of them adopt ground-level raising methods, but with the change in people’s consumption concepts and eating habits, the feeding mode of high-quality broilers is dominated by free-range rearing and grazing. As for the management, the whole feeding cycle is regulated and standardized. Management, in line with NY5037-2001 Guidelines for the use of broiler feeds and NY/T5038-2001 Feeding and management guidelines for broilers. (II) Production of broiler-free broilers must be scaled, industrialized, produced and managed on a small scale, and cannot be used to deal with the human market. The implementation of a biosafety system cannot guarantee pollution-free production. In the face of international market competition, we must implement large-scale industrialized production and management, implement pollution-free production standards, register product trademarks, and pass ISO international certification and HACCP certification, break through technical trade barriers, and gain access to the international market.
