There are a very wide range of antimicrobials available to the modern practitioner, not only with different ingredients but also with different durations of action. It could be argued that the emergency clinician does not actually require any long-acting preparations as the task required is urgent antimicrobial therapy which, if not effective in 24 h, requires adjustment in either drug type or dosage. This may certainly be the case when cattle are being treated by experienced farmers, but when treating cattle for smallholders with poor handling facilities, or when treating cattle kept in extensive conditions, e.g. when they are out on open land (range) or on marshland, a different approach will be required that entails the use of longer acting antimicrobials. Another factor to be considered is the stress induced by handling yarded cattle on a daily basis, particularly beef cattle with pneumonia. In these cases too long-acting preparations will be required. The author would, therefore, advise that ambulatory practitioners carry a minimum of a selection of five different types of injectable antibiotics with at least two potentially long-acting preparations. At least one oral and one topical antimicrobial will also be required.
