Abomasal Displacement in Dairy Cows: Welfare and Treatment

Key Facts

• LDA affects 2-8% of dairy cows, typically in the first two weeks after calving
• Risk factors include hypocalcaemia, ketosis, retained placenta, and low feed intake around calving
• Clinical signs include reduced milk yield, reduced rumen sounds, metallic tinging sound on auscultation-percussion
• Surgical correction (omentopexy) is the treatment of choice with excellent outcomes when performed promptly
• Prevention through transition cow management, adequate fiber, and correction of metabolic disease is highly effective

Welfare Considerations

LDA causes significant welfare suffering through pain and reduced feed intake. Affected cows are inappetent, lose body condition rapidly, and may develop secondary ketosis. The displaced abomasum causes abdominal discomfort and altered gut motility. Welfare-centered management involves prompt diagnosis and surgical correction — cows treated within 24-48 hours of diagnosis recover dramatically faster than those with prolonged delay. Pain management with NSAIDs alongside surgery significantly improves welfare outcomes. Prevention through rigorous transition cow management eliminates most LDA cases entirely.

What You Can Do

• Monitor all cows closely in the first 2 weeks post-calving for reduced appetite and milk yield
• Provide adequate fiber in the transition diet to maintain rumen fill and prevent abomasal displacement risk
• Treat LDA promptly with surgery — delayed correction increases recovery time and welfare cost
• Use NSAIDs perioperatively as standard welfare practice for all LDA corrections
• Address concurrent metabolic disease (ketosis, hypocalcaemia) that increases LDA risk and slows recovery
