In the process of laying hens in laying hens, the laying hens have a short growth cycle and a large number of breeding densities. Farmers should pay special attention to the work of chicken prevention procedures, and do a good job of disease prevention can reduce the incidence of disease. Currently, the most commonly used method for preventing diseases is immunization, which is a key method for preventing infectious diseases. The following author will tell the farmers about the key points of the chicken prevention process in the process of using layer chicken cages to raise chickens.
1. Reasonable formulation of immunization procedures: How should farmers raise immunization procedures? It should be based on the epidemic status of the region, what diseases have occurred in the region before or now, and then focus on prevention and rationally formulate the immunization program for the disease.
2. It is necessary to choose a high-quality vaccine and immunization method reasonably: whether the immunization is effective or not has a lot to do with the farmers when they choose the vaccine. The quality of the vaccine is related to the effect of the vaccine. Farmers should choose a formal biological product factory, and pay attention to the production date, warranty date and product description on the vaccine package. In addition, we must pay attention to master the correct vaccination method. The commonly used methods are eye, nose, drinking, prickly seed, aerosol, injection and other vaccination routes. Farmers can choose a reasonable method according to the disease and their own conditions.
3. Pay attention to the reaction after vaccination: After the vaccination, farmers should pay attention to some chickens will only show some adverse reactions, the most common is respiratory symptoms. After being vaccinated with the Newcastle disease attenuated vaccine and infectious bronchitis vaccine, especially in winter, if the farmer's house is poorly ventilated and the air in the house is dirty, the flock appears to shake his head, flick his nose, and breathe rales. Those with mild reactions disappeared within 2 to 3 days; those with severe symptoms can drink erythromycin and multi-dimensional electrolysis, appropriately raise the temperature of the house, and strengthen ventilation to control.
4. Avoid immune stress: In order to avoid the stress caused by vaccination, the farmer is vaccinating with eye drops, nose drops and other immunization methods. It should be noted that anti-stress drugs should be used 4-5 hours before immunization to avoid death caused by stress.
5. Pay attention to the use of combined vaccines: some vaccines need to be used in combination. Generally, many vaccine manufacturers have combined them to make combined vaccines, such as the new two-combined vaccine, etc. A variety of vaccines will be used in combination to avoid antagonism between the vaccines, resulting in poor immunity.
6. Vaccination of sick chickens is not allowed: Farmers should pay attention to the immunization of chickens in sub-health or disease during the immunization of chicken prevention procedures. When the group is vaccinated against this disease, its side effects will be strongly manifested, causing these chickens to die quickly, so you should wait for the sick chickens to recover before vaccinating.
The above is for the farmers. During the process of laying chickens in laying hen cages in Uganda, farmers should pay attention to some matters and some techniques when immunizing chickens. It is also the main point of preventive procedures for farmers to raise chickens. I hope that the above description can help farmers better complete the flock immunization work, avoid diseases, and improve the farmers' economic benefits.
