Aflatoxins (AFS) are groups of toxin fungal toxins that are produced by different species of fungi such as Aspergillus flavus and Aspergillus Parasiticus. In this study Aflatoxin and two adsorbents (Zeolite and Mycosorb) was added to diet to evaluate some blood biochemical and enzyme activities in broiler chickens. Zeolite and Mycosorb added into the treatment basal diets at 3 g/kg and 1 g/kg levels which is contaminated level of 0.5 (AF0.5) or 1 ppm (AF1) aflatoxin/kg.
A total of 189 broiler chicks were divided into 9 treatment groups: T1) Control, T2) AF0.5, T3) AF1, T4) Zeolite + (AF0.5), T5) Zeolite + (AF1), T6) Mycosorb + AF0.5, T7) Mycosorb + AF1, T8) Zeolite + Mycosorb + AF0 and T9) Zeolite + Mycosorb + AF1. The results showed that AFS in T2 and T3 groups in comparison with control caused a significant decrease in red blood cell, haematocrit and lymphocyte counts while the monocyte cell and hetrophil counts increased at the end of experiment (p < 0.05). The Billirubin values, Aspartate Transaminase (AST), Gamma Glutamil Transferase (GGT) and Lactate Dehydrogenase (LDH) activities in diets containing AFs (T2 & T3) increased significantly compared with the controls (p < 0.05). The addition of Mycosorb and Zeolite to the AFs containing diet significantly improved haematolagy parameters, billirubin value, and AST, GGT, LDH activities. The protective effect of Mycosorb (T6 & T7) was higher than that of Zeolite (T4 & T5) against the toxic effects of AFs. The results of this study showed that the addition of both organic and inorganic adsorbents to the AFs containing diet reduced the adverse effects of AF and could be helpful in a solution of aflatoxicosis problem in poultry.
