With three cases of Johnes Disease having been confirmed in sheep recently, local central west veterinarian's are urging producers to keep an eye on their flocks.
The slow onset, insidious disease is caused by the bacteria Mycobacterium paratuberculosis which can be present for years on a property before clinical signs become obvious.
Whilst it is no longer a disease requiring quarantining of the affected property, producers are required to notify Local Land Services District Vets if they suspect it might be in their stock.
Central West Local Land Services District Veterinarian Dr Jillian Kelly said signs to watch out for included wasting of adult sheep, with or without scouring.
"Once we are notified we can do a disease investigation, confirm the diagnosis and discuss management options including eradication or vaccination depending on the circumstances. Sheep can be vaccinated to reduce the impact on farm, Dr Kelly said.
The vaccine is given once in a sheep's lifetime, prior to 16 weeks of age.
