Hypocalcemia is a well-known issue in the dairy industry, but that’s not the case for why cows become hypocalcemic. Jesse Goff’s work, along with other peers’ research, points to metabolic alkalosis.
“The cows are alkalotic as a result of the potassium in the forages they are fed,” says Goff, Iowa State University professor and dairy veterinarian.
Prevention is a key component to addressing the issue, Goff says. Still, his perspective is because every dairy is different, addressing hypocalcemia through prevention is not a one-size-fits-all venture.
