Investigations are underway following the death of cattle on board a ship travelling from King Island to Devonport.
10 of the 38 animals on board were either dead on arrival or had to be put down by Tasmanian biosecurity officers due to their condition.
A stock trailer containing the animals is believed to have tipped aboard the 'Searoad Mersey' during the voyage.
More than 2000 cattle are shipped from King Island to Devonport every month.
This incident follows the deaths of 59 cattle aboard the MV Statesman while travelling across Bass Strait a year ago.
