Mastitis in sheep
Clinical mastitis (CM) in sheep is typically classified as acute (sudden onset) or chronic (subclinical mastitis persists with occasional onset of clinical signs) and may be severe or mild. It can result in death of the ewe, visible swelling, abnormal discharge from or pain in the udder, altered milk composition (Firat 1993; Gonzalez et al. 1990; Hovinen et al. 2008; Klaas et al. 2004), lethargy, anorexia and increased rectal temperature (Arsenault et al. 2008).
