Capability of dietary supplementation of composite toxin binder in reducing aflatoxin B1 toxicity and its immunomodulation in rainbow trout (Oncorhynchus mykiss) fingerlings

In the present study, the effects of aflatoxin B1 (AFB1) and a compound binder on blood cell count, biochemical indices of serum and liver histology of rainbow trout was investigated. In this regard, total number of 414 trout fingerlings (9.67±1.20g) were randomly allocated into six different treatments comprising various dietary inclusion levels of AFB1 (0, 25 and 50 ppb) and binder (0 and 5%) for 60 days. At the end of experiment, blood indices did not differ amongst treatments. The highest and lowest levels of ALP activities were observed in treatments fed diets containing 5% binder-25 ppb AFB1 and the group without any dietary aflatoxin and binder inclusions, respectively (P
