Abstract

One hundred and forty one-day-old-male broiler chicks (Ross), were divided into 7 groups (20 chicks/group) and fed T-2 toxin alone or with five different types of adsorbents; Montmorillonite 0.5%, Vermiculite 0.5%, Pigacine 0.5%, Gezilgure 0.5%; and the resin Perlite 0.5%. Gross and microscopic examinations reveal that all adsorbents used were unable to alleviate the oral lesions induced by T-2 toxin in broiler chickens.

Highlights

Trichothecene mycotoxins are produced by Fusarium and its perithecial stages (1)
Most studies related to the alleviation of mycotoxicosis by the use of adsorbents are focused on aluminosilicates, mainly zeolites and Hydrated sodium calcium aluminosilicates(HSCAS), and aluminumonsilicate-containing clays
Results of the current study indicate that broiler chicks fed diet contaminated with 8 ppm T-2 toxin develop oral lesions

Summary

Introduction

Trichothecene mycotoxins are produced by Fusarium and its perithecial stages (1). T-2 toxin, one member of group A trichothecenes, was first isolated from fusarium tricictum strain T-2 by Bamburg (2) and Bamburg et al, (3). Most studies related to the alleviation of mycotoxicosis by the use of adsorbents are focused on aluminosilicates, mainly zeolites and Hydrated sodium calcium aluminosilicates(HSCAS), and aluminumonsilicate-containing clays. HSCAS contain calcium ions and protons which are exchanged against the naturally occurring sodium ions. They are a type of montmorillonite belonging to phyllosilicates which are composed of layers of aluminum and silicon connected in a 1:1 or 2:1 arrangements. The aim of the present study was to evaluate different adsorbents; Montmorillonite (HSCAS); new aluminosilicte-containig clays (Vermiculite, Pigacin, Gezilgure); and new polymer resin (Perlite), in an attempt to alleviate necrotic oral lesions induced by feeding T-2 toxin to broiler chickens
