Abstract

The antibiotic therapy in the lactation period can help producers and practitioners to control bovine mastitis caused by Staphylococcus aureus and to reduce the duration of the intramammary infections. Mammary quarters from animals with subclinical mastitis were treated and the milk characteristics before and after therapy in different stages of lactation and parities were investigated. Thus, mammary quarters were classified according to stages of lactation (one to 60 days in milk; 61 to 120 days in milk; 121 to 180 days in milk; longer than 180 days in milk) and parities (first three lactations; fourth and fifth lactations; longer than fifth lactation). The antibiotic therapy was more efficient in cows with more than 180 days in milk and with six or more lactations. In dairy farm studied, the characteristics chosen (somatic cells count, milk production, chloride levels, titratable acidity, total solids, solids non-fat and milk fat) should be not used to select animals to treatment or discard.
