Do injection site swellings and lesions indicate decrease in vaccine response?
Dr. Glenn Selk, Extension Cattle Specialist, Oklahoma State University
University of Arkansas beef specialists conducted an experiment to compare the clostridial antibody response of 8 month-old heifers that do develop OR do not develop visible injection-site lesions and swelling. Blood samples were collected on day 0, 28, 56, 84, and 112 after injection with a 7-way clostridial subcutaneous vaccination. The vaccinations were given in the neck with a pistol-grip syringe using the tented technique.
