MANEJO CLÍNICO DE MASTITE COM NECROSE MAMÁRIA EM VACA LEITEIRA: RELATO DE CASO

Abstract

Chronic mastitis is a persistent inflammation of the mammary gland, characterized by irreversible tissue changes and the constant presence of infectious agents, commonly associated with environmental or contagious pathogens. Clinically, it may present with abnormal secretion, with dark coloration and presence of exudate, as well as reduced milk production and quality. This study describes a case of chronic mastitis in a Jersey cow treated at a dairy farm in the municipality of Orizona, Goiás. The animal presented clear signs of inflammation in the right posterior mammary quarter, in addition to persistent purulent secretion. There were failed attempts at treatment with intramammary tubes, which were later replaced by a protocol with systemic antibiotics and intravenous anti-inflammatory drugs. Identifying the etiological agent through microbiological culture was fundamental for therapeutic targeting and disease control in the herd. Early diagnosis and appropriate management are essential to minimize economic losses and preserve udder health.
