Australian Accredited Veterinarians (AAV’s) are required on all journeys which are considered long haul, if the vessel is transporting pregnant animals and when directed by government.
It is the AAV’s duty to treat any sick or injured animals in designated hospital pens. If the animal requires euthanasia the AAV’s have the appropriate medical equipment supplied onboard to humanely carry this out.
If an animal is found deceased in a pen, they are moved to specified points where a post-mortem is carried out to ensure the welfare of remaining animals. All sickness and death are recorded daily and sent to the Australian Federal Government.

Depending on the type of illness the animal may have, treatment will vary however the general procedure is:

Identify the animal and what is believed to be the issue or cause of the livestock’s concern.
If required, pull the animal out of its pen and move it to a hospital pen where it can be isolated and treated without being potentially injured more by other livestock in a confined space.
Each vessel is equipped with a range of medicines that the stockman will administer to the animal as required.
Continue to monitor and treat the animal accordingly.
