Abstract

The clinical and bacteriological efficacy, the quantity of mg and florfenicol treatment length for infectious bovine keratitis (Moraxella bovis) was assessed using either the parenteral administration of florfenicol (PF), or the ophthalmic administration of the drug in spray (OF). Sixty four cows and heifers were randomly divided into the two referred treatments. All animals were cured, however, the OF group required a mean of 378 mg/bovine and 12 days of treatment, while the PF group needed 22 800 mg/bovine (3.8 treatments per bovine) and 7.6 days. Although 100% efficacy was obtained in both groups cost-benefit ratio in the OF group is pondered
