Effect of stress on enteric pathogen shedding

Fasting or feed withdrawal for no more than two days is commonly used 

Among the studies that have investigated the effect of transport, the prevalence of E. coll 0157 H7 in cattle after transport and outdoor temporary confinement (lairage) did not increase and remained slightly lower than at the farm (Minihan et al., 2003). In a recent report that investigated the effect of transport duration on the prevalence of serotype 0157 in calves that had been fed pasture, Bach et al. (2004) indicated that animals that were transported for approximately 13 hours were more susceptible to infection after arriving
