The new label approval affirms that Guardian provides six-month duration of immunity (DOI) for E. coli K99 protection. This positions Guardian as the only multi-valent bacterial and viral combination scours vaccine with six-month DOI for E. coli – the longest proven DOI on the market. Scours is estimated to cost the beef industry hundreds of millions of dollars annually,” says Dr. Kevin Hill, Technical Services Veterinarian for Intervet/Schering-Plough Animal Health. “And E. coli is one of the most lethal bacterial agents causing calf scours. The new Guardian six-month E. coli DOI claim means beef producers can vaccinate with a high level of confidence knowing that Guardian will provide E. coli protection as early as 6 months prior to calving, reducing the need for inconvenient vaccination and handling during late-term pregnancy.
Scours can have a detrimental impact on the health and performance of calves. Anytime the intestinal tract is damaged, absorption is affected and performance impaired. Vaccination timing for pregnant cows is critical to stimulating and optimizing antibodies in colostrum. If cows are vaccinated too early the antibody response may start to fall off prior to the colostrum being made. Vaccinating too late and the colostrum may be made before an antibody response is mounted.
