It is important to prevent and treat diseases according to the occurrence of diseases. Vaccination campaigns against Newcastle Disease (ND) or Fowl Pox should be implemented before the onset of the disease, as the vaccine otherwise may kill already sick birds. To plan vaccination and medication, it is advisable to use a so called “disease prevention calendar”, where veterinarians, farmers and extension workers together identify the periods, where diseases should be prevented or treated.
