“…The possible reason might be that montmorillonite had a low effectiveness on DON and T-2, which still affected the reproduction of red-crowned crane. In future studies, new methods including modified montmorillonite and biodegradation should be developed for the decontamination of T-2 and DON [40,41].…”

The red-crowned crane (Grus japonensis) is a vulnerable bird species. Mycotoxins are toxic substances produced by filamentous fungi and are considered as naturally unavoidable contaminants in animal feed. Our recent survey indicated that feeds designed for captive red-crowned cranes were contaminated with mycotoxins. This study was conducted to investigate the protective effects of the mycotoxin binder montmorillonite on the reproductive behavior, sex hormone levels, and egg quality of red-crowned cranes. Twelve pairs of G. japonensis were divided into four groups, and each group was fed one of the following: a selected diet (with extra low levels of mycotoxins), a regular diet, a selected diet with 0.5% montmorillonite added, or a regular diet with 0.5% montmorillonite added. Consumption of the regular diet decreased courtship and mating behaviors, testosterone concentration, egg weight, and shell thickness. However, feed supplementation with montmorillonite increased the courtship, mating behaviors and testosterone concentration during the pre-breeding period, as well as egg weight and shell thickness. These findings suggest that the addition of dietary montmorillonite is effective for controlling mycotoxins in the feed, resulting in improvements in reproductive behaviors, testosterone concentrations, and some egg quality parameters of the red-crowned crane.

“…The active sites of raw MMT with layered structure, however, are usually covered by some impurity [ 7 ], which leads to high consumption but low adsorption capacity [ 8 ]. Therefore, some methods of modification for raw MMT are studied to improve its adsorption performance [ 9 , 10 ]. For example, the organic modifications and thermal treatment of MMT are two important methods to improve the adsorption performance of raw MMT [ 11 ].…”

“…Recently, some studies have indicated that the layers of raw MMT could be deeply exfoliated by acid treatment, which is an essential means to change its physicochemical property [ 10 , 19 ]. The acid-modified montmorillonites possess more active sites at the terminal hydroxyl surface, a larger specific area and higher pore volume than raw MMT.…”

“…For example, our research verified that the layers of raw MMT would be delaminated to 2–3 layers after acid treatment under H 2 SO 4 /raw MMT mass ratio of 0.3 and high temperature conditions, not only resulting in the impurity of raw MMT being removed, but also more active sites being exposed. Therefore, the adsorption efficiency of aflatoxin B1 (AFB1) in alkaline conditions is obviously improved over the modified MMT, increasing from 29.3% to 97.7% at pH = 8.0 [ 10 ].…”

Raw Ca-based montmorillonite (MMT) was treated by H2SO4, calcination and organic compounds (hexadecyltrimethyl ammonium bromide (HTAB), cetylpyridinium chloride (CPC) and chitosan (CTS)), respectively. The modified montmorillonites were characterized by different methods and their adsorption performances for three mycotoxins (Aflatoxin B1 (AFB1), zearalenone (ZEA) and deoxynivalenol (DON)) were evaluated at pH = 2.8 and 8.0, respectively. The results indicate that surfactants (CPC and HTAB) intercalation is the most efficient modification, which obviously improves the adsorption performance of montmorillonite for mycotoxins, with adsorption efficiency of above 90% for AFB1 and ZEA whether under acid or alkaline conditions, due to the increase in basal spacing and the improvement of hydrophobicity. Moreover, the adsorption efficiencies of AFB1 and ZEA over CPC-modified montmorillonite (CPC-AMMT-3) coexisting with vitamin B6 or lysine are still at a high level (all above 94%). All modified montmorillonites, however, have low adsorption efficiency for DON, with somewhat spherical molecular geometry.

“…Among the mycotoxin binders, phyllosilicate clays are the largest group and have been used in numerous research trials [ 27 , 28 , 29 ]. Different studies demonstrated that mineral adsorbents including bentonite, zeolite, montmorillonite, and hydrated sodium calcium aluminosilicate can bind or adsorb mycotoxins to their interlayer spaces, external surface, and edges [ 21 , 30 , 31 , 32 ]. Montmorillonite, an aluminum silicate, is characterized by a permanent negatively charged surface and exchangeable cations in the interlayer space.…”

The goal of this study was to investigate the toxicokinetic characteristics of aflatoxin G1 (AFG1) in broiler chickens and the effect of calcination of a Tunisian montmorillonite clay on the in vivo absorption of AFG1. In this study, broiler chickens were randomly distributed into four groups of 10 animals. Group 1 was administered AFG1 (2 mg/kg body weight (BW)) by single intravenous injection (IV), group 2 received an intra-crop bolus (PO) of AFG1 without any clay, group 3 was dosed AFG1 PO together with an oral bolus of purified clay (CP), and group 4 received AFG1 PO with an oral bolus of calcined clay. A significant difference in the area under the curve (AUC0-t) was observed for group 4 (6.78 ± 4.24 h*ng/mL) in comparison with group 2 (12.83 ± 4.19 h*ng/mL). A significant reduction of the oral bioavailability of AFG1 was observed for group 4 (7.61 ± 4.76%) compared with group 2 (14.40 ± 4.70%), while no significant effect was observed of CP. In this experiment, no phase I nor phase II metabolites of AFG1 were observed. These findings confirm that calcination of the purified montmorillonite clay enhances the adsorption of AFG1 in the gastrointestinal tract after oral administration, thereby reducing its bioavailability, thus reducing its toxic effects.
