This study was conducted to evaluate the protective efficacy of clinoptilolite (CLI, a natural zeolite) in the prevention of toxic effects of aflatoxin (AF). A total of 576 1-day-old Ross broiler chicks were housed in six treatment groups [six replicates of 16 each; control, CLI (15 g kg–1diet), 50 parts per billion (ppb) AF, 50 ppb AF plus CLI, 100 ppb AF, 100 ppb AF plus CLI ] for 42 days. Compared to controls, 100 ppb AF treatment significantly decreased body weight gains of chicks. The addition of CLI to the 100 ppb AF - containing diet moderately reduced the adverse effects of AF on performances of chicks. The chicks consuming 50 ppb AF -containing diet showed no significant differences on investigated parameters compared to controls. Also, the single addition of CLI to theAF -free diet had no adverse effects in birds. These results suggest that CLI can be beneficial in broilers for protection of AF toxicity at the level above.
