Abstract

Oral infection of chicken groups at 31 day of age with field isolate of toxogenic C. perfringens Type A resulted in subclinical necrotic enteritis diagnosed with post- mortem and histopathological lesions in intestine and liver from the 3rd day post infection with C.perfringens culture. The only detected clinical signs were general signs of low feed intake and low conversion rate in infected groups as compared with the negative control group.  Aflatoxins and/or coccidia vaccine act as predisposing factors for NE. Weekly and total body weight gain (BWG), feed intake (FI) and conversion rate (CR) at the 1st wpi in aflatoxin and coccidia vaccine group was the lowest, followed by that of coccidia vaccine group; while that of aflatoxin group was the highest. Post mortem, microscopical lesions and lesion score in sacrificed chickens treated with aflatoxin and/or coccidia vaccine were more severe than culture infected group. Bursal and thymic microscopic lesions have been detected in all infected groups. Experimentally, subclinical NE was induced in presence of aflatoxin and/or coccidia vaccine as predisposing factor by a single dose of C. perfringens broth culture.
