A Warning for Livestock Owners: The Hidden Danger of Lupin Stubbles
In the wake of the recent summer rains, a critical health concern has emerged for livestock producers in the Wheatbelt region. We're talking about lupinosis, a liver disease that has been reported in sheep flocks, particularly in the southern areas where lupin crops are increasingly being grazed as standing crops.
But here's where it gets controversial: even modern narrow-leaf lupin varieties, known for their phomopsis resistance, can still develop lupinosis under the right conditions. This means that the valuable feed source of lupin stubbles requires careful management to avoid this potentially devastating disease.
Dr. Judy Burson, a field veterinary officer from the Department of Primary Industries and Regional Development (DPIRD), urges producers to be vigilant. "Early detection is key," she emphasizes. "Subtle signs like reduced appetite, loss of condition, and disorientation when driven should not be ignored. These could be the first indicators of lupinosis."
As the disease progresses, symptoms become more severe, including blindness, head-pressing behavior, a hunched appearance, and yellowing of eye membranes and the mouth. If you notice any of these symptoms, Dr. Burson advises immediate action: "Remove affected stock from the paddock and seek veterinary advice for a proper diagnosis."
The treatment process is lengthy, often taking up to six months for a full recovery. Affected livestock require a special diet, with quality hay and small amounts of oats, but no lupins, as their damaged livers cannot handle high-protein diets.
And this is the part most people miss: lupinosis symptoms can mimic other diseases, including exotic diseases not native to Australia. That's why a professional diagnosis by a veterinarian is crucial. The Significant Disease Investigation Program offers subsidies for investigations that rule out emergency diseases, aiding in early detection.
So, what can you do? Stay informed. Check out the DPIRD's Lupinosis webpage for detailed information on identification and management. And if you have any concerns, don't hesitate to reach out to your private veterinarian or a DPIRD field veterinarian. Your flock's health is worth the extra effort!
Remember, staying ahead of potential health issues is always better than playing catch-up. Stay vigilant, Wheatbelt producers!
