1. Polyvinylpolypyrrolidone (PVPP), synthetic zeolite (SZ) and bentonite (BNT), when incorporated into the diets at 3, 5 and 5 g/kg respectively, were evaluated for their ability to reduce the deleterious effects of 2-5 mg aflatoxin (AF; 83-06% AFB1 12-98% AFB2, 2-84% AFG1, and 1-12% AFG2,)/kg diet on growing broiler chickens from 1 day to 3 weeks of age. A total of 210 chicks were divided into 10 treatment groups (control, AF, PVPP, AF plus PVPP, PVTP plus SZ, AF plus PVPP plus SZ, PVPP plus BNT, AF plus PVPP plus BNT, AF plus SZ and AF plus BNT) each consisting of 21 chicks. 2. When compared to control, the AF treatment significantly decreased serum total protein, albumin, inorganic phosphorus, uric acid and total cholesterol, and the values of haematocrit, haemoglobin, mean corpuscular haemoglobin, thrombocyte counts, percentage of lymphocyte and monocyte counts; increased values of white blood cell and heterophil counts. 3. Decreased serum albumin caused by AF was significantly ameliorated by PVPP plus BNT. A similar increase was obtained in serum total cholesterol by adding BNT to the AF-containing diet. 4. The serum uric acid, white blood cell counts and percentage of lymphocyte and monocyte counts were numerically intermediate between control and AF values in all of the adsorbent treatments containing AF. The change in thrombocyte counts was alleviated by all of the adsorbent treatments containing AF, except AF plus SZ. The addition of the adsorbents in the AF-free diets did not significantly alter the serum biochemical and haematological parameters compared to controls.

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-1 diet), 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 the AF-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.
