Local farmers are being warned to carefully monitor their livestock, and take precautions against bloat, with a number of cases already reported this season.
Regional Veterinarian with Riverina Local Land Services Eliz Braddon says animals are at risk of bloat when they're grazing on young, rapidly growing pastures, especially if there's more than 50% clover or lucerne.
Symptoms include a reluctance to eat or move, and distension of the left flank.
Early intervention to treat mild cases with an anti-bloat drench will give cattle the best chance of recovery.
Left untreated, bloat can quickly cause compression of the lungs, obstruction to blood flow and death.
