Determination of serum aflatoxin B1-lysine and biochemical parameters in broiler chicks fed an aflatoxin B1-contaminated diet
In the present trial, the levels of serum aflatoxin B1 (AFB1)-lysine and their relationship with biochemical parameters in broiler chicks fed an AFB1-contaminated diet were determined. The experimental design was completely randomized with two treatments (control and 222.17 µg/kg AFB1) and 20 bird per treatment. Feeds were offered to broiler chicks for 14 days, from 28 to 42 days of age. Animals were vaccinated against Newcastle's and Marek's diseases on the 14th day of life, and were killed at 42 days of age. Broilers receiving AFB1 did not demonstrate any sign of toxicity. Compared with controls, aspartate aminotransferase and globulin levels were not affected in the AFB1-treated group. However, higher levels of gamma-glutamyl transferase and lower concentrations of total protein and albumin were observed in the group receiving AFB1 on days 35 and 42. AFB1-lysine were detected in the serum of all broilers fed the AFB1-contaminated diet, at mean levels of 56.52-77.83 ng/mg albumin on days 35 and 42 of age, respectively. These values indicated the internal dose of AFB1 in birds, which negatively correlated with total protein, albumin, and globulin levels. Data indicated that AFB1-lysine shows the potential to be a sensitive and specific biomarker for the evaluation of broiler exposure to dietary aflatoxin, as well as for diagnostic purposes. Further studies are necessary to determine physiologically-based toxicokinetics of serum AFB1-lysine in broilers.
