Despite all our efforts to grow healthy calves, “we still have sick animals,” says John Champagne, veterinarian and service chief of dairy production medicine at the University of California-Davis Veterinary Medicine Teaching and Research Center in Tulare, Calif.
“From that standpoint, one of the big issues is being able to find those animals and find them sooner rather than later,” he said during a wet lab at the 2012 Dairy Calf & Heifer Conference. “Our success rate, regardless of the treatment, is going to be better off in that early disease state.”
Setting a good foundation also is important, and is the basis of disease prevention in calves. Aim for excellence in transition cow management, colostrum management and calf nutrition, not just for proper growth and development, but also to give calves the ability to deal with infections, Champagne said. Pathogen control and optimum husbandry practices also pay big dividends in the management of respiratory and gastrointestinal diseases of calves.
