use was 21 percent less in diets for
pigs that were reported suffering
from diarrhea. Finally, electrolyte
balance was relatively reduced in
diets for scouring pigs (-8 percent).
Although this study does not establish a clear cause-effect relationship between dietary composition
and Escherichia coli diarrhea, it
provides at least an indication that
improper diet formulation can predispose pigs to diarrhea, intensify
symptoms, or delay recovery.

bacterial complications.  
■ Restricted feeding. This practice was particularly popular
in Europe. Weaned pigs were
offered a limited amount of
feed during the first week postweaning, with increasing allowances of feed until pigs attained
ad libitum levels during the second week. The development of
modern diets and later weaning

Intervention strategies

Edema disease, a complicated
enteric disorder caused by enterotoxemic Escherichia coli strains,
continues to puzzle veterinarians and
nutritionists regarding prevention
and treatment of affected animals.
A Dutch research group examined
affected and healthy pigs from
the same herd and concluded that
although edema disease is closely
associated with the presence of
Escherichia coli (O139K82 strain in
this case), dietary factors may also
contribute or aggravate this intestinal
disorder. Affected pigs exhibited
symptoms of metabolic acidosis, evidenced by higher blood and intestinal
acidity. The researchers speculated
that toxins produced by Escherichia
coli in the gastrointestinal tract may
have a greater chance to cross the in-

It should be emphasized that
nutritional interventions after the
onset of diarrhea should be made in
consultation with the attending veterinarian and nutritionist. Because
scientific experiments with infected
pigs raised alongside healthy pigs
in the same room are practically
invalid, practical experience rather
than scientific evidence is usually
the basis for deriving most recommendations. Farms experiencing
high incidents of post-weaning
diarrhea can follow one or more of
the following measures:
■ Prevention. For bacterial diarrheas, measures prescribed for
antibiotic-free diets are equally
applicable. For viral diarrheas,
however, vaccination is most
helpful, although antibacterial

age, along with the use of creep
feeds and/or milk replacers have
all but virtually made such practice impractical. In addition, a
field study from Denmark where
restricted feeding used to be the
norm, revealed that restricted
feeding may not always be as effective against diarrhea as previously thought.  
■ Reduced anti-nutritional
factors. Soybeans and most
legumes contain anti-nutritional
compounds that have the potential of triggering the immature
digestive immune system of the
weaned piglet, with inflammation and diarrhea usually following ingestion of high doses
of such anti-nutritional factors.
