What is one sign of mastitis in ewes?

Swelling and redness of the udder is a primary clinical sign of mastitis in ewes. Mastitis, which is an inflammation of the mammary gland, often leads to observable changes in the udder's appearance. When an ewe has mastitis, the affected udder may become swollen due to inflammation and may also show redness as a result of increased blood flow to the area. This combination of swelling and redness is a visual indication of the infection or inflammation present, prompting the need for veterinary intervention to address the condition effectively.

In contrast, the other options do not correlate with signs of mastitis. For instance, increased appetite, heavy wool growth, and bright eyes are not typically associated with mastitis. In fact, animals suffering from mastitis may experience a decreased appetite due to discomfort or pain, rather than an increase. Recognizing the specific signs of mastitis is crucial for timely treatment and maintaining the health of the flock.
