The disease is distributed worldwide either clinical or subclinical form, causing reduction body weight gain and feed conversion ratio, impairing European Broiler Index Production Efficiency Factor. There are several predisposing factors development of NE. Clinical signs varied from inapparent case infection (clostridiosis) obvious enteric (morbidity), followed an mortality level (clostridiosis infection). laboratory diagnoses based on history, signs, gross histopathological lesions, pathogenic agent identification, serological testing, molecular identification. Drinking water treatment most common route for administration antibiotics, such as penicillin, bacitracin, lincomycin. Strict hygienic management practices farm, careful selection ingredients ration formulation, use alternative antibiotic additives all important maintaining efficiency help profitability production. current review highlights NE caused C. perfringens explains advances understanding virulence involved pathogenesis special emphasis available alternatives herbal extracts essential oils well vaccines control prevention chickens.
