A 28-d experiment was conducted to evaluate the effects of fumonisin B<SUB>1</SUB> (FB<SUB>1</SUB>) on hematological and serum biochemical parameters of young laying Japanese quail fed fumonisin contaminated rations. To this end, 128 7-wk-old birds were randomly distributed into four experimental groups (32 birds per group) and fed rations containing 0 (control), 10, 50 or 250mg FB<SUB>1</SUB>/kg feed. Each treatment consisted of four replicates of eight quail. At the end of the trial, blood samples from 12 birds per treatment were collected and submitted to analysis. Compared with controls, quail fed 250mg FB<SUB>1</SUB>/kg for 28 days had reduced (P<0.05) red blood cell counts and hematocrit values. No differences (P>0.05) were found among leukocyte counts obtained in control birds and FB<SUB>1</SUB>-treated groups, and a lower percentage of lymphocytes (P<0.05) was observed in birds fed 50 and 250mg FB<SUB>1</SUB>/kg. Serum protein, albumin, γ glutamyl transferase and uric acid were similar (P>0.05) among the treatments studied. Aspartate aminotransferase concentrations were higher (P<0.05) for birds receiving 10, 50 and 250mg AFB<SUB>1</SUB>/kg, when compared to the control group. Results indicated that FB<SUB>1</SUB> at levels≥10mg/kg is toxic in young laying quail, emphasizing the importance of controlling fumonisin contamination of quail rations.
