Abstract

The use of SRP® E. coli vaccine technology effectively decreases the prevalence of E. coli O157:H7 in feeder cattle, thus making it a valuable tool for increasing food safety in the beef industry. However, questions continue to be raised about the vaccine effects on economic drivers in cattle feeding. The aim of the study was to assess the effect of vaccinating cattle three times with SRP® E. coli vaccine technology verses a placebo (control) on performance, health, and carcass characteristics of cattle fed in commercial feedlots.
