If multiple injections are given, keep them several inches apart. Do not give more than 10 ml per injection site. If injections are given on multiple occasions over several days, vary injection site day to day. Use these especially carefully. Recent studies suggest that clostridial vaccines should not be given late in the feeding period, should be given SQ in all age cattle and preferably in front of the shoulder.
Sanitation is essential .
Change needles frequently, 10-20 uses or syringe full of vaccine. Inject only into clean areas- avoid mud, manure, etc. Thoroughly clean and disinfect equipment between uses. Keep working facilities clean, from the work table surface to the holding chute. Maintain treatment records and identify treated animals .
