Iodine is applied to the severed umbilical cord of a piglet to prevent the entry of microorganisms into the piglet.

By applying iodine to the umbilical cord, it disinfects the area and prevents the entry of microorganisms such as bacteria into the piglet, reducing the risk of infection and disease.
