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.

The amelioration of aflatoxicosis in broiler chickens was examined by feeding two concentrations of natural zeolite (clinoptilolite). Clinoptilolite (CLI), incorporated into the diet at 1.5 and 2.5 per cent, was evaluated for the ability to reduce the deleterious effects of 2.5 mg total aflatoxin (AF) kg-1 diet on growing broiler chicks from 1 to 21 days of age. A total of 360 broiler chicks were divided into six treatment groups [Control, AF, CLI (1.5 per cent), AF plus CLI (1.5 per cent), CLI (2.5 per cent), and AF plus CLI (2.5 per cent)] each consisting of 60 chicks. Compared to controls, the AF consuming chicks showed increases in the relative weights of liver and kidney; and gross-histopathologic hepatic lesions such as paleness, friability, diffuse hydropic degeneration and/or fatty change, bile-duct hyperplasia and periportal fibrosis. Glumerular hypertrophy, increases in the number of mesengial cells and hydropic degeneration of tubuler epithelium in kidneys of chicks fed diet AF alone were also observed. Atrophy and lymphoid depletion were seen in the thymuses and bursa of Fabricius from the chicks fed AF alone. The additions of CLI (1.5 and 2.5 per cent) to the AF-containing diet moderately (significantly in some cases) decreased the number of affected broilers and/or the severity of lesions. The addition of CLI to the AF-free diet did not produce any significant changes compared with the controls. These results suggest that CLI was effective for the protection of AF-toxication in broilers and it could contribute to a solution of the AF problem in poultry production. © 2001 Harcourt Publishers Ltd.
