🐑Do you have Liver Fluke? 🐄
Liver fluke (Fasciola hepatica) isn't just a nuisance—it’s a production killer. Whether you're running sheep or cattle, these parasites can cause massive internal damage before you see a single symptom in the paddock.
Here’s what you need to look out for to protect your flock and herd:
🔍 Physical "Red Flags"
While cattle tend to be more resilient, sheep can go downhill fast. Watch for:
"Bottle Jaw" (Submandibular Oedema): A soft, fluid-filled swelling under the jaw. This is a classic sign of a heavy, chronic fluke burden causing protein loss.
Pale Gums & Eyes: Check the mucous membranes. If they look white or porcelain-pale instead of healthy pink, your stock is likely anaemic from fluke feeding on their blood.
"Ill-Thrift": Animals that look "hollow," have ragged fleeces (sheep), or rough, dull coats (cattle) despite being on good quality pasture.
Sudden Death: In "acute" cases (common in sheep), a massive intake of young fluke can cause the liver to bleed internally. Often, the first sign is finding a dead animal that looked fine the day before.
