Some husbandry factors influencing weaning stresses in piglets.

The post-weaning diarrhoea syndrome (PWDS) in piglets is multi-factorial in origin. Numerous managemental, environmental, housing, nutritional, immunological and physiological factors are discussed, being primary factors in the cause of the PWDS. Infectious agents especially Escherichia coli are often incriminated as causes of PWDS but are more likely to be opportunistic elements due to faulty management of stressed animals.
