The Hazard of Aflatoxins on Poultry and Its Detoxification

Aflatoxins are secondary metabolites from some aspergillus with strong teratogenic,carcinogenic and mutagenic functions.One of those,aflatoxin B1 is the most toxic,which may result in injury to digestive function,immunologic suppression,reduction of growth performance,such as feed utilization,accumulate in tissues(such as liver,kidney and muscle),and also potential risk to animal's health and food safety.Aflatoxicosis usually occurs in infant chicks,ducklings and turkeys.Especially,the chicks and ducklings at 2 to 6weeks of age are extremely sensitive to AFB1.The detoxification methods of aflatoxins are mainly physical,chemical,adsorbent,and biological methods at present.The hazards of aflatoxins on poultry,the detoxification theory and research situation of detoxification technology as well as the application prospect were summarized in this paper.
