An udder is a mammary gland found in female mammals, particularly in livestock such as cows, goats, and sheep. It is responsible for producing milk to nourish their young. The udder typically has multiple teats, which are the openings through which milk is delivered. In dairy farming, the udder is crucial for milk production. Farmers often milk animals by hand or with machines, ensuring the udder is healthy and clean to maintain milk quality. Proper care of the udder helps prevent infections and ensures the well-being of the animal, contributing to a sustainable dairy industry.
