Which antibiotic is often used topically in hoof conditions?

• A. Penicillin
• B. Oxytetracycline
• C. Tetracycline systemic
• D. Ceftiofur

Answer: (B)

This item tests which antibiotic is commonly used topically for hoof infections. Oxytetracycline is the classic choice for topical hoof therapy because it’s formulated specifically for surface application to the hoof and interdigital space. It delivers broad-spectrum activity directly where the infection sits, remains effective in the presence of dirt and moisture, and can be applied as a spray, powder, or paste, giving a high local concentration without needing systemic dosing. Penicillin and ceftiofur are largely used systemically or by routes other than topical application, and a tetracycline given systemically isn’t the same as a topical hoof treatment. So the topical, hoof-focused option that’s most commonly used is oxytetracycline.
