Abstract

E.coli O157:H7 is a contaminant of E.coli O157:H7s and has been associated with food-borne illnesses in humans. Recently an E. coli SRP® vaccine received conditional licensure in the United States for the control E. coli 0157 in cattle. E. coli is also a common disease agent responsible for causing post-natal calf diarrhea. Colostrum management is recognized as an important factor for calf health and survival. Calves that fail to consume an adequate amount of colostrum within the first 12-24 hours after birth are at a higher risk for disease, death, and decreased performance. The objective of this study was to determine if E.coli O157:H7 SRP® specific antibodies could be detected in the serum of calves that consumed colostrum from dams that were vaccinated prior to calving with E.coli O157:H7 SRP® vaccine.
