The last part of biosecurity is maintaining the health and vaccination level of your animals. Good nutrition, low stress levels, and a well-implemented vaccination program will limit the severity when disease hits. The vaccination program should be tailored to your individual dairy by a veterinarian familiar with the operation. However, a vaccination program needs frequent monitoring and is only as good as its implementation. Achieving good biosecurity is not easy.
Success requires planning, implementation, and adjustment as the dairy operation expands.
