Why is sheep after shearing dipped into an antiseptic?

After shearing, sheep are often dipped into an antiseptic solution to prevent infections and control parasites. The process helps protect the skin from potential cuts and abrasions that can occur during shearing. Dipping also aids in managing external parasites, such as lice and ticks, ensuring the overall health and well-being of the flock. This practice is crucial for maintaining wool quality and preventing disease spread.
