In an interview with Mid-West Farm Report, Dr. Kendra Wells of Valley Vet Clinic highlights a shift in how dairies view their youngest members. Gone are the days when calves were seen as an eventual payday. Today, calves are treated as high-stakes, high-value investments from day one.
Wells defines “precision calf care” as a data-driven approach that moves away from one-size-fits-all management. She attributes this change to a shift in herd demographics. With the use of sexed semen and beef-on-dairy breeding, farms are raising fewer replacement heifers. That means every individual calf must succeed.
“Precision calf care, in my mind, is just really narrowing it down… tailoring my program to have those goals met,” Wells explains.
This approach involves everything from specialized facility design to advanced medical screenings. One example is the use of lung ultrasounds to catch pneumonia before a calf even shows outward symptoms. Because calves are prey animals, they are experts at hiding illness until it is often too late for simple intervention, Wells says.
The next frontier for the dairy barn is wearable technology. While collars and ear tags are common for adult cows, Wells predicts a surge in monitoring tools for calves to track rumination and health metrics.
“I’m excited to see that type of technology come so we can actually say, ‘I am raising a calf that ruminates now,’ versus ‘I took her off of milk; I hope she does fine,'” she says.
By utilizing data from smart ear tags and boluses, veterinarians and farmers can determine the exact right moment to wean a calf or identify a struggling group before a herd-wide issue develops. As Wells noted, the industry is moving away from “hoping for the best” and toward a future where data ensures every calf reaches her full potential.
