Veterinarian Kendra Wells with Valley Veterinary Clinic tells Stephanie Hoff that the dairy industry has shifted its perspective on calves, moving from seeing them as future earners to recognizing them as the immediate, high-value "future of the farm." Due to the use of sexed semen and beef semen, farms are raising fewer replacement heifers, meaning each individual calf must be of higher quality than in the past. Veterinarians are increasingly using lung ultrasounds to detect pneumonia lesions early, as calves are prey animals that instinctively hide symptoms of illness until they are severe.
