Abstract

Aflatoxins (AFs) are groups of toxin fungus that are produced by different species of fungi of Aspergillus flavusand Aspergillus parasiticus. In order  to evaluate the effect of different levels of aflatoxin B1 in diet on the performance, total of 450 Japanese quail at 1 d of age were studied in a completely randomized design with 6 treatments and 5 replications (15 pieces in each replication). Treatments consisted of five levels of aflatoxin B1 in the diet (50, 100 200, 500, 1000 ppb) with a control group (without aflatoxin B1), respectively.At 28 d of age, of each experimental unit 2 chickens after collection of blood samples, Slaughtered and internal organs weighed individually.The presence of aflatoxin B1 in the diet was significantly reduced feed intake and body weight gain at 28 d of age. At the end of the fourth week, with increasing levels of aflatoxin B1 in diets, liver and gizzard weight indicated a significant increase and decrease, respectively. Diets contaminated with aflatoxin B1 indicated significant effect on blood parameters so that with increasing levels of aflatoxin B1 decreased total protein and glucose levels in blood. Overall, the results of this study showed  that the presence of aflatoxin B1 in quail's diet, Caused adverse effects on blood parameters, Viscera weight and performance of Japanese quail. thus importance of emphasizing on birds'diet (quail) redoubleto control pollution
