Abstract
The present invention provides for a method of injecting an antibiotic in the ear of an animal, such as cattle, swine, sheep and goats. These injectable antibiotics include the following: injectable suspensions of sparingly water-soluble antimicrobial agents, such as procaine penicillin, benzathine penicillin, ceftiofur crystalline free acid ceftiofur hydrochloride, ampicillin trihydrate and amoxicillin trihydrate; sustained-release non-aqueous solutions of sparingly water-soluble antimicrobial agents, such as oxytetracycline, erythromycin, tylosin, tilmicosin and florfenicol; and injectable solutions of zwitterionic antimicrobial agents, such as enrofloxacin, danofloxacin and premafloxacin. Specifically, the present invention provides for a method of injecting a relatively large volume (1 to 15 mL) of a sterile oil suspension of an antibiotic, such as ceftiofur crystalline free acid, in the posterior of the ear of cattle and swine.
