Relationship of sex, age, and concurrent intestinal disease to necrotic enteritis in turkeys.

A retrospective case-control study of necrotic enteritis in turkeys was done. Male flocks were involved in a significantly greater proportion of necrotic enteritis cases compared with control cases. Necrotic enteritis cases occurred most frequently between 6 and 11 weeks of age. Within this age range, the probability of a necrotic enteritis case having a concurrent intestinal disease diagnosis was significantly higher than the probability in control cases. Coccidiosis was the most frequently diagnosed concurrent intestinal disease with necrotic enteritis, followed by clinical hemorrhagic enteritis and ascaridiasis.
