Monitoring rumen temperature as an indicator of receiving calf health

Sims, Lindsay Eileen
Remote monitored rumen temperature boluses were administered to newly received feedlot heifers to determine their efficacy for monitoring body temperature and detecting heifers with high temperatures related to Bovine Respiratory Disease. A study was completed to determine the efficacy of the rumen temperature bolus system in a feedlot setting with high risk cattle. Remote monitored rumen temperature boluses detected increases in rumen temperature when heifers were suspected to be infected with Bovine Respiratory Disease. The rumen temperature bolus system was successfully integrated into a feedlot and resulted in an adequate number of transmissions and showed potential in identifying animals with Bovine Respiratory Disease.
