Figure 2

Enrofloxacin concentrations in glandular tissue after intramammary administration to 6 sheep. Administration was made with an injector containing 1 g enrofloxacin/5 g ointment. Samples were taken at constant vertical distances from the base of the teat. Significant differences were found between concentrations determined at 2 cm and at the rest of the heights. Theoretical values predicted with the equation Concentration = 478.804 · e^{-0.251 · height} are also included (short dash line). Data are given as box plots with median and quartiles (semilogarithmic scale).
