Abstract

The objective of this three-location study was to evaluate the initial and durable cure rates, and to determine the duration of therapy, for ceftiofur crystalline free acid sterile suspension (CCFA-SS) for treatment of bovine respiratory disease (BRD) when a 3, 5 or 7-day retreatment moratorium was imposed. This study tested the hypothesis that retreatment during the period of effective plasma concentrations of ceftiofur may not improve treatment success rates.
