Guidelines on the Disease during the Conversion Period

• Vaccine choice and use should be agreed with the nominated veterinary surgeon to ensure adequate disease protection during the conversion period.
• Where possible, reduction in the use of clostridial vaccines should be part of the overall animal health plan.
• Where bacillary haemoglobinuria is a problem, management changes may need to be put in place to prevent liver fluke.
• Similarly, where malignant oedema and tetanus are a problem, good hygienic measures should be taken during castration, calving assistance and other surgical procedures.
