emphasized the importance of basic
management in preventing necrotic
enteritis and managing its spread
once it presents itself.
■ Litter quality: Wet litter means
the risk of necrotic enteritis is
higher. Some anecdotal evidence
suggests that necrotic enteritis
is actually worse on clean litter than it is on built-up litter.
McElroy said that's possibly
because positive microbial populations exist in built-up litter and
removing it can be detrimental.
Some farmers see success with
acidifying the environment.
■ Lighting programs: Farmers need
to consider how the lighting program is stressing the bird and if
that's influencing bird health.
■ Water quality and sanitation: In
a similar vein, clean feeding and
watering equipment is important
to control disease risk. Farmers
should check systems to ensure
cleanliness and clean feed pans
to prevent buildup of fecal matter
or other undesirable substances.
■ Temperature stress: One factor
farmers may not consider is the
role of heat or cold stress on the
birds. When necrotic enteritis
appears, farmers need to examine their temperature logs and

look to see how the environment
changed - if it did change at all.
As always, stress can lead to
damaged intestines, which can
lead to heightened necrotic enteritis risk. ■
