What is one sign of mastitis in ewes?

Swelling and redness of the udder is a clear sign of mastitis in ewes. Mastitis is an infection of the mammary gland, and it typically leads to inflammation, which can manifest as swelling. The redness occurs due to increased blood flow to the affected area as the body responds to the infection. Additionally, the texture of the udder may become firm or hard, and there may be pain or sensitivity when touched. These physical changes are important indicators for shepherds to identify the condition early and treat it promptly to avoid further complications.

The other choices do not directly relate to mastitis. Increased appetite does not signify a problem in ewes; rather, it could indicate a healthy condition or a reaction to changes in feed. Heavy wool growth is a normal physiological feature influenced by breeds and environmental conditions, rather than a sign of an infection. Bright eyes typically suggest good health and vitality, contrasting with the signs of illness that mastitis presents. Recognizing the symptoms of mastitis, especially swelling and redness of the udder, is crucial for effective sheep management.
