6 major piglet diarrhea causes
and their management
There are a variety of causes of piglet diarrhea; understanding the
factors involved will help producers control it.
BY E. WAYNE JOHNSON

Suckling piglet diarrhea is the most common condition affecting swine, often resulting in high mortality and serious
economic losses. Morbidity due to mild and chronic piglet
diarrhea is an economic concern because of piglet weight
loss and the risk of permanent intestinal damage. An old
rule of thumb from research is that one day of suckling pig
diarrhea slows growth to market weight by five days.

Causes of piglet diarrhea
There are primary infections of the intestines that
cause diarrhea, but piglet diarrhea can result from systemic viral infections such as porcine respiratory and
reproductive syndrome (PRRS), pseudorabies or classical swine fever. Conditions affecting the sow or her
ability to produce milk may result in diarrhea in her piglets. Complex causations with both sow and piglet factors are common. Excessive milk production in lactation
is seldom a root cause of piglet diarrhea, but lactation
failure does frequently lead to piglet diarrhea. Neonatal
piglets are dependent upon antibodies in colostrum and
milk for protection against pathogens. Causes of lactation failure include sow constipation, over-conditioned
sows, sub-optimal culling and infectious porcine anemia
due to " Haemoplasma" (Eperythrozoon) suis.

Coccidiosis

Coccidiosis is a mild diarrhea in piglets
older than five days that is not bloody but can
be any color: white, yellow, green or brown and often
changes color. Diagnosis is by histopathology, mucosal smears or observing fecal oocysts. Coccidiosis

Diarrheas are a major problem worldwide,
causing significant economic losses due to
morbidity and mortality.
can be prevented by oral toltrazuril given on day five. 
Disinfection with 1 to 2 percent sodium hypochlorite
(NaOCl) destroys oocysts. Coccidiosis seldom kills
piglets but damages the small intestine.

Clostridia

Clostridium perfringens type C causes
a severe acute fibrinonecrotic enteritis in the
neonatal pig with black or bloody feces and rapid high
mortality, but chronic forms exist.  C. perfringens type
A is more common, occurs at any age and causes a
mild diarrhea resembling coccidiosis. Piglets recovering from clostridial diarrhea express non-uniform
growth. Diagnosis of clostridial diarrhea is made by
necropsy, intestinal smears, histopathology, culture and
toxin testing. Commercial or autogenous sow vaccines
are preventative. Amoxicillin is a common piglet treatment. Bacitracin at 250 ppm in the lactation diet and
sporocidal disinfectants reduce piglet exposure. Vitamin
E/Se deficiency may trigger clostridial diarrhea.
