Epidemic prevention and control measures for small and medium-scale laying hen farms

1. Ensure that the all-in and all-out system is in place. The implementation of the all-in and all-out breeding system is an important measure to reduce the cumulative spread and development of laying hen diseases. It is mainly required to introduce chicks of the same age and breed into the chicken house at the same time, and then sell them at the same time after they are mature. After the disinfection of the chicken house is completed quickly and uniformly, the next batch of chicks is introduced. However, only a small number of small and medium-sized farms can meet this requirement. Therefore, the all-in and all-out breeding system is strictly implemented in accordance with the requirements to reduce the frequency of diseases in laying hen farms, increase the rate of weight gain of laying hens, and reduce their mortality. While strengthening production cost control, it can improve higher economic benefits.

2. Strictly control the breeding environment through biosecurity measures. Clean the breeding environment at regular intervals, provide sufficient drinking water, vitamins, minerals and other resources for laying hens, replace feed in a step-by-step manner, and reasonably keep the house warm, heat preservation, low tide, ventilation, etc. In the process of raising chickens, farmers need to pay more attention to the prevention and control of infectious diseases, strictly implement sanitation and disinfection treatment and isolation management, reduce the incidence of bacterial diseases, and control the occurrence and spread of respiratory diseases and immune system diseases. Minimize the occurrence of viral and bacterial diseases and secondary lesions.

3. Improve the quality of immunization work. The drugs used for the treatment of chickens in small and medium-scale chicken farms need to be fully considered. It is necessary to pay attention to epidemic prevention and control management on the basis of ensuring safety, and apply correct epidemic prevention measures to small and medium-scale chicken breeding to ensure a certain period of time. The offspring of the flock are also immune to the spread of disease. When vaccinating chickens, it is necessary to fully consider the current group status and disease development trends of the chickens, and comprehensively consider the characteristics of their living areas to formulate a vaccination plan. It is necessary to fully consider the age of the chickens and the specificity of the vaccine for epidemic prevention. , do not blindly vaccinate. The best time to vaccinate chicks is from the 13th to the 15th day. The vaccine needs to be selected according to their age. About 5 days after the vaccination is completed, if pimples or redness are found, the vaccination is successful, and vice versa. It indicates that the vaccination failed and needs to be re-vaccinated. In addition, the population vaccine antibody test needs to be carried out within 30 days after vaccination. If the test requirements are not met, it is necessary to analyze the reasons and then re-vaccinate.
