Abstract: This is a case report of jejunal intussusceptions in a flock of pullets associated with necrotic enteritis of unconfirmed origin. The aetiology is a shift in gut micro flora. This is unlike the previously studied cases in commercial broiler flocks which have been associated with coccidiosis, ulcerative enteritis and anorexia. Imbalanced use of anticoccidial vaccines, anticoccidial drugs and Antibiotic Growth Promoters (AGPs) are the main cause of the gut micro flora shift. This is also the main cause of necrotic enteritis. The condition was successfully controlled with Augmentin (Amoxicilline+Clavulinic acid) at the dose rate of 25 mg kg-1 body weight for three days. To limit losses associated with this type of condition, there is need for research based legislative control on the concurrent use of anticoccidial drugs, anticoccidial vaccines and AGPs in developing countries.
