Which solution is commonly used to dip a newborn calf's navel to prevent infection?

• A. Alcohol
• B. Water
• C. Salt
• D. Iodine

Answer: (D)

Newborn calves have an open entry point at the umbilical stump, so applying an antiseptic helps kill bacteria right at the site as the stump dries. Iodine is used because it’s a broad‑spectrum antiseptic that acts quickly and tends to remain on the surface long enough to reduce microbial load during the critical first days. This protective effect lowers the chances of infection as the navel heals. Water doesn’t disinfect, salt isn’t an antiseptic, and alcohol can irritate delicate newborn tissue and doesn’t provide as lasting protection as iodine, making iodine the best choice among these options.
