Abstract

A farm of two broiler flocks fed from one day old to 56 days of age a diet naturally contaminated with high level of Aflatoxin (AF), were suffered from caecal coccidiosis at 35 days of age Aflatoxin levels in feed commodities and mixed feed were determined using ELISA test. Results of ELISA showed that the average level of corn, soybean and mixed feeds contamination with aflatoxin were 1915, ppb, 229 ppb and 860 ppb respectively. Diagnosis of caecal coccidiosis was confirmed by clinical signs, post-mortem findings, fecal oocyst excretion per gram, oocyt size, morphological characteristic of eggs, lesion score and schizonts size. The significance of AF as predisposing factor to coccidiosis infection was discussed.
