With the rapid development of the chicken industry, the establishment and improvement of the health and epidemic prevention system of chicken farms has become a key link to ensure the health of birds, improve the efficiency of breeding and ensure food safety. This paper will elaborate on how to build a scientific and effective chicken farm health and epidemic prevention system from the aspects of chicken farm site selection and layout, infrastructure construction, feeding management, disease prevention and control, waste treatment and biosecurity.
1. Site selection and layout of chicken farms
The site selection of chicken farms should follow the principles of being far away from pollution sources, convenient transportation, high and dry terrain, sufficient water sources and good water quality. The layout of the chicken farm should be reasonable, and the living area, production area, sick chicken isolation area, waste disposal area, etc. should be strictly separated to prevent cross-contamination. Clean roads and dirty channels should be set up in the production area to ensure that the transportation of clean items such as feed, drinking water, and eggs is not polluted.
2. Infrastructure construction
1.Chicken coop construction: The chicken coop should have good ventilation, heat preservation, moisture-proof, and sunscreen functions to ensure that the chickens live in a comfortable environment. The internal facilities of the chicken house, such as drinking fountains, feed troughs, and manure cleaning equipment, should be reasonably designed and easy to clean and disinfect.
2.Roads and drainage: The roads in the chicken farm should be smooth and hardened to facilitate vehicle traffic and cleaning. The drainage system should be improved to ensure that rainwater and sewage can be discharged quickly to prevent stagnant water from causing epidemics.
3. Feeding management
1.Feed & Water: Choose high-quality feed to ensure that the flock receives adequate nutrition. The water source should be clean, and the water quality should be tested regularly to prevent diseases caused by drinking water pollution.
2.Feeding density: Reasonably control the feeding density to avoid overcrowding of chickens and reduce the chance of disease transmission.
3.Immunization: According to the local epidemic situation and the immunization status of the flock, formulate a scientific immunization program to ensure that the flock is effectively immunized.
Fourth, epidemic prevention and control
1.Disease surveillance: Conduct regular health checks on the flock, detect suspected cases in time, and take measures such as isolation, ** or elimination to prevent the spread of the disease.
2.Disinfection measures: The inside of the chicken farm should be fully disinfected regularly, including chicken coops, drinking fountains, feed troughs and other facilities. Disinfectant drugs should be broad-spectrum, high-efficiency, and low-toxicity varieties to ensure the disinfection effect.
3.Introduction and quarantine: strict quarantine should be carried out when introducing seeds to ensure that the newly introduced chickens are healthy and disease-free. Newly introduced chickens should be isolated for a period of time to confirm that they are disease-free before mixing into the original flock.
4.Disease prevention: prevent the occurrence of epidemic diseases by improving the feeding environment, improving the immunity of chickens, and reducing stress factors. At the same time, it is necessary to pay close attention to the epidemic situation in the local and surrounding areas, and take prevention and control measures in a timely manner.
5. Waste disposal
Waste such as manure and sewage produced by chicken farms should be properly disposed of to prevent environmental pollution and the spread of diseases. Biological fermentation, composting and other methods can be used for harmless treatment, and waste can be converted into organic fertilizer to achieve resource utilization. The content of pathogens in the waste should be strictly controlled during the treatment process to ensure that it does not cause pollution to the environment.
6. Biosecurity
1.Personnel management: Chicken farm staff should undergo regular health check-ups to ensure that there are no infectious diseases. Before entering the production area, it is necessary to change work clothes, shoes, hats, etc., and disinfect them. Workers should follow hygienic practices in the chicken farm to avoid carrying pathogens into the production area.
2.Anti-rodent and insect-proof: Regular anti-rodent and anti-insect work should be carried out inside the chicken farm to prevent pests from carrying pathogens into the chicken coop. Physical, chemical or biological methods can be used to ensure the hygiene and safety of the internal environment of the farm.
3.Treatment of sick and dead chickens: Sick and dead chickens should be treated in strict accordance with the requirements of harmless treatment to prevent the spread of pathogens. It can be treated by incineration, deep burial and other methods, and relevant regulations and operating specifications should be followed in the treatment process.
To sum up, the construction of a scientific and effective chicken farm health and epidemic prevention system needs to start from many aspects, including site selection and layout, infrastructure construction, feeding management, disease prevention and control, waste disposal and biosecurity. Only by taking these factors into account can we ensure the health of the birds on the farm, improve the efficiency of the farm, and ensure food safety. In practice, each chicken farm should develop its own health and epidemic prevention system according to its own conditions and actual conditions, and constantly improve and optimize it to meet the development of the chicken industry and market demand.
