Adjust the inoculation time and adopt different inoculation methods.
1, adjust the vaccination time: the immune effect of blue ear disease vaccine is related to the vaccination time, and cows should be vaccinated before estrus to achieve the best immune effect. If cows are always vaccinated once every seven days, we can consider advancing or delaying the vaccination time to avoid the immune effect of the vaccine being too early or too late.
2. Adopt different vaccination methods: In addition to routine vaccination, different vaccination methods such as oral vaccine and nasal spray vaccine can be used to improve the immune effect and tolerance of the vaccine.
