Aflatoxin (AF) (0.5ppm) was tested in an in vivo study forming 2 dietary treatments each with three replicates on a total of 336 on broiler chicks up to six weeks. Results showed that chicks receiving AF contaminated feed had suppressed body weight and improved feed consumption. The serum antibody titers against ND and IBD vaccination were significantly depressed by AF. The serum concentration of total protein, uric acid and albumin were not affected in AF fed supplemented group. The activity of serum GGT significantly increased in AF fed group. Compared with control, activity of serum ALT was not affected in AF or control supplemented groups.
