Downer cow that has not calved and is ketotic with low calcium; what treatment would you give?

• A. Calcium-dextrose IV fluids
• B. Oral calcium carbonate
• C. Antibiotics
• D. Vitamin D supplement

Answer: (A)

Rapid correction of acute hypocalcemia in a downer cow that hasn’t calved is essential, and administering intravenous calcium along with a glucose (dextrose) source provides the fastest and most reliable relief. The IV calcium quickly raises circulating calcium levels, which improves muscle contractility and neuromuscular function, helping the cow stand. The dextrose supplies immediate energy to address the ketosis that often accompanies negative energy balance in late gestation, further stabilizing the animal. Oral calcium can be helpful in some cases, but it is too slow to correct a severe, recumbent hypocalcemic state and won’t quickly address the energy deficit. Antibiotics aren’t indicated unless there’s an infectious complication, and a vitamin D supplement by itself does not correct an acute calcium deficiency quickly enough to get the cow standing.
