Thoracic Ultrasound in Calves

By Dr. Liz Cox on Wed, Apr 29, 2020 @ 09:00 AM

A lot has changed since I wrote a blog post for EI Medical in 2011! I have a new last name, two little kids and I no longer use clippers when scanning calf lungs. I am still scanning calf lungs with my Ibex PRO/r and teaching veterinarians and veterinary students the technique. Out on farm and in research, we are now all using one scoring system developed by Dr. Terri Ollivett from University of Wisconsin.

Now we have another good excuse to cull cows due to bad temperament. Producers that routinely breed cows artificially realize that cows that are unruly and nervous are less likely to conceive to artificial insemination. Presumably, the lowered conception rates were because they have been stressed as they are passed through the working facilities and restrained while being synchronized and inseminated. Research trials indicate, even in the serenity of a natural breeding pasture, cows with bad dispositions are less likely to conceive when mated with bulls.

If you’re new to ultrasound, an image may look like nothing more than a swirling array of grey tones on the screen.  Interpretation requires an understanding of anatomy and physiology, but also of how ultrasound technology functions.

Consider the sonar produced by a bat in flight. The bat emits high frequency sounds, which then bounce off of objects in its proximity and return to the bat. The animal uses the strength, direction, and timing of the returning sound to determine where those objects are and to avoid a collision.
