Poultry chickens are not suitable for vaccination

In the process of keeping laying hens, some chicken farmers saw that the chickens entered the peak period of egg production. They feared that chickens were infected with infectious diseases and affected the production of eggs. The chickens were then vaccinated with Newcastle disease, infectious bronchitis, and other vaccines. The practice is unscientific. It will not only fail to achieve good preventive effects, but will also reduce the egg production of chickens and produce soft-shelled eggs, which will affect the health of the flock. In the spring and early summer seasons, the appetite of chickens is gradually prosperous, blood circulation is accelerated, and the number of immune antibodies in the serum is increased. Therefore, during this period, the chicken has the strongest production performance, the highest egg production, the best constitution, and the best spirit. If the chicken is vaccinated with Newcastle disease vaccine or other vaccines at this time, the normal physiology of the chicken will be destroyed, and some vaccines will even antagonize the naturally occurring antibodies of the chicken, which is extremely unfavorable to the chicken's egg production and health. Therefore, chickens entering the peak period of egg production should not be vaccinated, and the vaccination work should be carried out before the chicken is opened.
