Alternative injection sites for a Pasteurella multocida bacterin

Abstract

Seven different injection sites for a Pasteurella multocida bacterin were evaluated by measuring the immune response and the local tissue reaction. Injection into the ventral surface of the tail or subcutaneously along the dorsal midline of the neck were the most suitable procedures. Ease of application was judged subjectively, and the tail site was found to be easier to inject accurately than the subcutaneous neck site. The tail injection site was found to be the best overall when immune response, tissue reaction, and ease of application were all considered.
