It’s not the most appealing subject, but it is certainly in high demand at the Orange Agricultural Institute.
Residents who come across a recently dead rabbit are asked to contribute the carcass or liver to help researchers gain the upper hand in the biological warfare on the ferals.
By analysing the livers, NSW Department of Primary Industries scientist Tarnya Cox and her team are hoping to gain further insight into counteracting rabbits’ immunity to rabbit haemorrhagic disease (RHD).
A single strain of RHD was introduced in Australia in 1996 as a biological control method.
It controls up to 90 per cent of the rabbit population in some areas.
Scientists are now collecting specimens from RHD-affected rabbits to examine new strains that would be best at biological control and overriding current resistance.
“We are looking at up to 10 new strains from Europe and Asia,” Research leader Dr Glen Saunders said.
“Out of the 10 we will choose one or two.”
The most suitable strain will be selected in June, 2012 before being released in Australia over the following three to four years.
The resistance has formed after a benign strain of the disease developed in rabbits, particularly in high rainfall areas like Orange.
Researchers are hoping the new strain will help control more rabbits in these areas.
Dr Saunders said it was important to keep on the forefront of biological control methods due to their effectiveness.
