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 Japanese quails was examined by the dietary addition of live yeast (Saccharomyces cerevisiae; SCE). Yeast incorporated into the diet at 1 gkg-1 was evaluated for its ability to reduce the deleterious effects of 2.5 mg total aflatoxin (AF; 82.30 per cent AFB1, 2.06 per cent AFB2, 7.68 per cent AFG1 and 7.96 per cent AFG2) kg-1 diet on growing Japanese quail chicks from 10 days to 45 days of age. Forty 10-day-old Japanese quail chicks were assigned to 2 × 2 factorial arrangement of treatments (control, AF, SCE, AF plus SCE) each consisting of 10 quails. The performances of birds were evaluated. The AF treatment significantly and dramatically decreased food consumption and body-weight gain from the first week onwards. The significant adverse effect of AF on the food conversion ratio was also determined from week 1 to the end of the experiments. The addition of SCE to the AF-containing diet significantly reduced these deleterious effects of AF on food consumption, body-weight gain and food conversion ratio. Compared to controls, the cumulative body weight gain was reduced by 37 per cent among the quails consuming AF without SCE, but increased 15 per cent for the birds fed AF plus SCE. Interestingly, the single inclusion of SCE to the AF-free diet provided significant improvements in all the investigated growth performances of birds (approximately 40 per cent) compared to controls. © 2001 Harcourt Publishers Ltd.
