The type of iodine typically used on cow milk udders for sanitation and hygiene purposes is known as “teat dip” or “iodine teat dip.” Iodine teat dip is a disinfectant solution formulated to help prevent bacterial contamination and infection in dairy cows’ udders during milking.

Iodine teat dip is available in various formulations, including water-based or alcohol-based solutions. It usually contains iodine as the active ingredient, often in the form of povidone-iodine or elemental iodine. Iodine is chosen for its effective antimicrobial properties and its ability to reduce the risk of mastitis, a common udder infection in dairy cows.

Teat dipping is a standard practice in dairy farming to maintain udder health and ensure the quality and safety of milk. It is used before and after milking to sanitize the teats and minimize the risk of bacterial contamination.

The specific formulation and use of iodine teat dip can vary among dairy farms, but the primary goal is to promote udder hygiene and safeguard the health of dairy cows while maintaining milk quality.
