As the number brassica crops bloom across Orange, sheep and cattle farmers are warned of the potential health risks and management for the animals.
District veterinarian Nigel Gillan said he advises farmers to remain vigilant and to keep an eye on the animal while they are grazing on the paddock.
"I have recently seen suspected cases around Orange of cattle being sick from eating the crops," he said.
"If you notice any changes in behaviour to call your vet or the district vet so we're able to diagnose and help the animal."
According to Mr Gillan, the crops that can impact the animals around Orange include canola and winfred forage brassica.
He also added there isn't a huge percentage of sheep and cattle impacted but some of the problems that can occur include sudden death due to nitrate toxicity, blindness, photosensitisation and bloat.
"Some suggestions to help the animals include laying out good quality straw or hay to assist with digestion and consider moving stock from the crop when dull or cloudy weather is present," Mr Gillan said.
"It is important to raise awareness about the health issues that can arise and I want to make sure farmers don't panic about allowing their sheep or cattle to graze on the crop as it can be managed."
