The first option is to immunize the blue ear inactivated vaccine. After a large number of experiments show that the inactivated vaccine on the protection of blue ear disease is not strong, in the wild virus infection pressure or the body immunity decline when the epidemic is prone to occur, this immune method of pigs basically no protective effect.
The second scheme is not immune blue ear vaccine, but with antibiotics to control mycoplasma and bacterial secondary infection, this method in the pig body immunity is normal, feed nutrition balance or short-term can control the outbreak of blue ear. However, once the pig herd is subjected to environmental pressure or stress, it may explode and spread at any time.
The third option is to immunize the blue ear attenuated vaccine. This method has a good effect on the control of blue ear disease in pigs, but the following points need to be paid special attention:
1, vaccination must be under the condition that the individual is healthy;
2, vaccine immunization time is very important (protective antibody levels, need enough immune response time);
3, the body immunity regulation, feed nutrition level, environmental pressure;
4, choose the right vaccine, suitable for their own pig products;
5, do a good job in each stage of vaccine antibody detection, grasp the overall immune antibody level of pigs.
