๐LDA in Dairy Cattle: A Ping That Saved a Life
๐ฏ Real-Time Diagnosis (90%) & Field Surgery (10%)
๐จ Emergency in the Fresh Cow Pen
Today Iโm sharing a real case that reflects the true power of clinical skills in the field
๐ฌ Left Displaced Abomasum (LDA) โ a condition that silently strikes within 60 days post-calving, especially in high-producing cows
This post is for every ๐งโโ๏ธ veterinarian, ๐ฉโ๐ vet student, and ๐ dairy farm professional committed to herd health and field-based excellence
As we move from diagnosis to surgical correction using only clinical experience, a stethoscope, and toggle suture technique โ all done in field conditions, without high-tech tools.
๐ Case Summary
๐ History
โ๏ธ Early-lactation dairy cow
โ๏ธ Feed intake less
โ๏ธ ๐ฉ Pastry-like f***s
โ๏ธ ๐ก๏ธ Normal temperature
โ๏ธ Calm demeanor โ but subtle signs of internal distress
๐ Ping Sound Detected
Using percussion + auscultation on the left paralumbar fossa (between the 9th and 13th ribs), we identified the classic โpingโ โ indicating gas in a displaced abomasum
๐ง Treatment Toggle Suture Technique
๐ ๏ธ Steps in the Field
1๏ธโฃ Animal in dorsal recumbency (legs upward)
2๏ธโฃ Ping site reconfirmed
3๏ธโฃ Toggle sutures applied precisely at the ping site
4๏ธโฃ Abomasum anchored back into position
5๏ธโฃ Supportive therapy and post-operative care provided
โ
Simple
โ
Affordable
โ
Highly effective in low-resource, field-based settings
๐ง Key Learning for Fresh Vet Graduates
โ Why LDA Happens (Mostly 0โ60 Days Post-Calving)
๐ผ High-concentrate, low-fiber rations
โ๏ธ Negative energy balance
๐งซ Metritis, ketosis, retained placenta
๐ง Hypocalcemia, reduced rumen fill
๐ Diagnosis
๐ The "ping" remains your most valuable diagnostic tool โ no need for expensive gadgets when your hands, ears, and brain are sharp
๐ Early intervention Animal saved, production restored, and economic loss prevented
โ๏ธ Master techniques like toggle-pin fixation โ critical for field success in developing regions
Other Techniques for LDA Correction
๐งต 1 Toggle Suture Fixation
โก๏ธ Field-friendly, quick, economical
๐ช 2 Right Flank Omentopexy
โก๏ธ Surgical approach via the right side fixes the abomasum using the omentum
๐๏ธ 3 Right Flank Pyloropexy
โก๏ธ Anchoring the pylorus to the abdominal wall
๐ 4 Left Flank Abomasopexy
โก๏ธ Direct suturing of the abomasum through the left side (more invasive)
๐ 5 Rolling + Cast Technique (Temporary)
โก๏ธ Cow rolled into dorsal recumbency to allow abomasum to float back โ not a permanent fix
โ
Post Surgical Outcome
๐ Feed intake improved
๐ Rumen motility restored
๐ฅ Milk yield resumed
๐ Cow fully recovered
๐ฐ Economic loss avoided
