Minimising risks

Minimising risks

For detailed information, see the 2013 Drystock Biosecurity Guidelines.


  • Purchase stock from reputable and biosecurity-conscious suppliers
  • Check the vaccination histories of purchased animals
  • Making every effort to assess the health status of incoming stock, including closely examining stock yourself for signs of disease.
  • Only purchase stock from flocks with the same or a higher health status than your own flock. (This could refer to such areas as parasite resistance or Johnes status)
  • Insist on a vendor’s declaration as to the health status and treatment history of the stock.
  • Treat incoming stock with appropriate parasite drenches and vaccinations and hold stock for a period of no less than 24 hours upon receipt to allow them to empty out in the yards.
  • Refrain from mixing incoming stock with other stock instantly so as to monitor the animals
  • Investigate and treat all animal illnesses and make sure you call the vet in the case of unusual symptomsIsolate infected stock from health stock
  • Avoid grazing young stock with older stock


  • Thoroughly clean and disinfect yards after bringing deer in for weighing, drafting or animal health treatments
  • Provide a fenced off area for disposal of carcasses
  • Ensure boundary and internal fences are adequate and maintained to prevent unwanted movement of livestock in or out of your property

Equipment and vehicles

  • Clean and disinfect equipment after use and especially if using hired or shared equipment.  See the attached best practice guidelines on practical steps to maintain biosecurity in relation to farm machinery and vehicles.

There is the potential for property contamination from visitors and their vehicles, including veterinarians, other producers, stock and station agents, shearers, shooters, fishermen. shepherds and musterers.

  • Minimise unnecessary movement of people and non-property owned vehicles
  • Encourage use of protective clothing 
  • ensure routine cleaning of visitors’ boots and hands, for your safety and theirs

Boundaries and wildlife (wild animals)

  • Act upon incidences of wild animal activity around dead stock.
  • Coordinate action against wild animals with neighbours to maximise effectiveness
  • Carefully manage rubbish dumps or offal pits as they may attract wild animals onto your property

Documentation and management

  • Comply with NAIT rules and regulations on tagging and deer movements to ensure lifetime traceability of stock and ease of management in a disease incursion.
  • Develop and implement an animal health plan to minimise disease in the herd and facilitate identification of unexpected diseases
  • Investigate and treat all animal illnesses and make sure you call the vet in the case of unusual symptoms
  • Get post-mortems carried out on unexplained stock deaths
  • Record any increase in pests or weeds on your property or surrounding areas. Such pest and weeds could include rise in possum numbers or spread of gorse or other noxious plants on the Regional council 'watch lists'
  • Minimise the spread of noxious plants by use of chemical or other methods as advised by your Regional council. Ensure when you are working with chemicals that you follow all instructions and safe handling practices.
