Diagnosing livestock diseases
Good animal health and livestock welfare is fundamental to farm productivity. Improved husbandry practices and the capacity to prevent, diagnose, and treat livestock disease contributes to an increase in individual animal and whole-herd performance as well as a reduction in livestock mortality.
Our district veterinarians and Local Land Services officers are on the ground to support livestock managers across NSW to assist with diagnosing animal diseases to maintain livestock health.

Arthritis in sheep can be caused by a variety of bacteria entering the bloodstream via cuts and/or wounds in the skin.
Barber's pole worm infestation in sheep and goats causes anaemia and results in death if left untreated.
Bloat in cattle and sheep is the accumulation of gas in the rumen and is a risk when animals are grazing young pasture with high legume content.
Bovine Ephemeral Fever, or Three Day Sickness, is a viral disease of cattle that is spread by mosquitoes and biting midges.
Fleece rot is the result of bacterial infection on the skin and in the fleece of sheep that results in dermatitis and wool damage.
Flood Mud Scours or Yersiniosis is commonly seen after flooding and can cause a severe diarrhoea and death in cattle.
Foot and mouth disease is a highly contagious animal disease that affects all cloven-hoofed animals including cattle, sheep, goats, camelids (eg alpacas, llamas and camels), deer and pigs.

Liver fluke parasite infects a range of mammal hosts and causes liver damage and blood loss.

Red Gut or intestinal torsion is a severe intestinal accident seen in sheep grazing lush green pasture.
Strawberry Footrot is caused by a combination of bacterial and viral infection which produces lesions around the feet and mouth, and is a common cause of lameness in sheep.

Theileria can cause infections and potentially severe clinical disease in cattle with range of symptoms.
