Effect of diet type on post-weaning diarrhoea in ETEC-challenged pigs and susceptibility towards F4ab/ac fimbriae

摘要

Post-weaning diarrhoea (PWD) caused by certain serotypes of enterotoxigenic E. coli (ETEC) is a major problem in weaner pigs. In the development of PWD, the stress pigs experience plays an important role (Pluske et ah, 1997). Factors such as sub-optimal room temperatures, changes in the type of food and shifts in the gut microbiota could all increase the risk on PWD. The relative impact of these factors on faecal consistency was tested in weaner pigs with different susceptibilities for F4 fimbrial attachment.
