Key Facts

• Prevention focuses on reducing oral trauma that allows Actinobacillus lignieresii entry
• Sharp stemmed roughage, wire, and poor-quality hay increase oral injury risk
• Clean water troughs and feeders reduce oral contamination with the pathogen
• Early identification of cases allows effective treatment before disease advances
• Regular examination of the head and neck of cattle identifies early cases

Welfare Considerations

Wooden tongue prevention is more effective than treatment because early lesions respond well to therapy while advanced cases may be refractory. Reducing oral trauma through feed quality management — avoiding sharp, stemmy roughage and ensuring feeders have no sharp edges — removes the entry point for infection. Regular stockperson examination of cattle heads and necks allows early detection of the characteristic hard swellings before welfare compromise becomes severe. Prompt treatment of early cases with sodium iodide prevents the progression to welfare-impacting dysphagia that characterizes advanced disease.

What You Can Do

• Inspect feeders and drinkers regularly for sharp edges that could cause oral trauma
• Avoid feeding excessively stemmy or sharp roughage to cattle
• Train stockpersons to recognize early signs of jaw or tongue swelling
• Act promptly when early cases are identified to prevent welfare deterioration
• Maintain clean, well-functioning drinkers to reduce bacterial contamination risk
