What is the term for the removal of wool around the dock and mammary glands of sheep?

The term that refers to the removal of wool around the dock and mammary glands of sheep is known as tagging. This practice is important for several reasons, including enhancing hygiene and preventing matting of wool, which can lead to health issues such as fly strike. By shearing this specific area, farmers can ensure a cleaner environment for the animals, making it easier to manage their care.

Dehorning relates to the removal of horns in cattle, which is not applicable here. Castration refers to the removal of the reproductive organs, not related to wool management. Shearing is the general process of removing fleece from sheep, which encompasses the entire body and does not specifically refer to the targeted area mentioned in the question. Tagging specifically addresses the need for cleanliness and management in a precise area of the sheep, making it the correct answer in this context.
