“…This result is supported by the findings of some other previous studies, in which the feeding of a diet contaminated with purified T-2 toxin had caused significant increases in the malondialdehyde content of the liver (Mézes et al, 1998;Dvorska and Surai, 2001). However, contamination of the feed with AFB 1 and T-2 + HT-2 toxin together did not show any significant effect, which means that the two abovementioned mycotoxins have no additive effect on lipid peroxidation in the liver.…”

Three groups of cockerels were fed with a control diet, with a diet contaminated with T-2 and HT-2 toxin (0.31 and 0.26 mg/kg) or with that containing a combination of T-2 and HT-2 toxin (0.32 and 0.25 mg/kg) and aflatoxin B 1 (AFB 1 , 0.38 mg/kg) for 21 days. Body weight gain and feed conversion ratio did not differ significantly among the groups. Malondialdehyde concentration of the liver was lower in the group fed the diet contaminated with the combination of T-2 + HT-2 toxin and aflatoxin B 1 as compared to the control group or the group fed T-2 + HT-2 toxins. Reduced glutathione (GSH) content of the liver was lower in the T-2 + HT-2 group than in the group fed a combination of T-2, HT-2 and aflatoxin. Reduced glutathione content of the heart was higher in the T-2 + HT-2 group than in the control group. Mycotoxin contamination had no effect on glutathione peroxidase (GSH-Px) activity in comparison to the control, but significantly lower GSH-Px activity was found in the heart of chickens in the T-2 + HT-2 + AFB 1 group than in the T-2 + HT-2 group. In this study, T-2 + HT-2 toxin and aflatoxin B 1 contamination of the diets did not affect the production traits adversely and did not exert additive effects on lipid peroxidation and on the glutathione redox system.

“…Enhancement of the humoral immune response after addition of binders like Humate or HSCAS in this investigation is in line with Ibrahim et al (2000) who citied that supplementation of sodium bentonite binder was significantly effective in ameliorating the negative effect of aflatoxin on the percentage and mean of phagocytosis and HI-titer in chicks vaccinated against ND. It has been reported that Humate significantly improve antibody levels in broiler chickens, fed graded levels of AF (Swamy and Devegowda, 1998), multiple mycotoxins (Raju and Devegowda, 2002) and also it inhibited lipid peroxidation in liver of quails fed T-2 toxin (Dvorska and Surai, 2001). HSCAS inclusion to AF diets improved (p<0.05) the ND and IBD titers and it is in accordance with Barmase et al (1990).…”

Key words:aflatoxin, broiler, adsorbent compounds, detoxificationThe objective of this study was to investigate the protective effect of dietary natural sorbent-Humate (0.2%) and Hydrated sodium calcium aluminosilicate (HSCAS) (0.5%) on the prevention of aflatoxin (AF) toxicity in the broiler chicken 7-35 days of age. Two hundred and forty broiler chicks were randomly divided into four treatment groups of 4 replicates (each contained 15 chicks). While chicks in group 1 were fed a basal diet free of toxin (control), group 2 chicks were fed a basal diet contaminated with 1ppm AF, the other two groups 3 and 4 were fed contaminated basal diet supplemented with 0.2% Biofarm® Dry humate, and 0.5% HSCAS, respectively. Parameters evaluated were growth performance, some serum constituents, some organs weight, and immune response to Newcastle disease and infectious bursal disease. The results showed that, Aflatoxin (1 ppm/kg) significantly reduced feed intake, weight gain and feed efficiency. Further aflatoxin increased the relative weights of liver, kidney, gizzard and spleen, while the relative weights of thymus and bursa of Fabricius were decreased by AF. Aflatoxin toxin also reduced antibody titres against Newcastle disease and infectious bursal disease. Modified 0.2% Humate significantly (P ≤ 0.05) improved body weight, feed intake, decreased relative organ weights and improved antibody titres, bursa of Fabricius and thymus weights. Hydrated sodium calcium aluminosilicate (0.5%) showed improvement against AF. The results of our experiment showed that 0.2% Humate and 0.5% HSCAS has a positive effect on the growth of broilers. And it could have been a suitable natural supplement for growing broilers against the adverse effects of aflatoxins.

“…a decrease in albumin (Nataraja et al, 2004) and an increase in total lipid, triglyceride and cholesterol (Mansour et al, 2002) contents as a result of T-2 toxin load. Vitamin E content of the liver in chickens fed a diet contaminated with T-2 toxin did not change as compared to the control birds, which was contrary to the results of a previous experiment with Japanese quails where a significantly lower vitamin E content was found in the liver but at a higher level (8.1 mg/kg) of T-2 contamination (Dvorska and Surai, 2001). Vitamin E supplementation in the drinking water together with feeding a T-2 toxin contaminated diet resulted in an opposite tendency in changes of liver vitamin E content during the first week of the experiment, but thereafter the vitamin E content of the liver decreased.…”

“…apolipoproteins (Bieri and Farrell, 1976;Mézes, 1988), due to the effect of feeding a T-2 contaminated diet during the first week of the experiment. During the second week of the experiment the stored vitamin E, even when present in a high concentration, underwent rapid oxidation due to increased lipid peroxidation in the liver, which was observed in some previous studies in which diets contaminated with T-2 toxin were fed (Mézes et al, 1998;Dvorska and Surai, 2001). …”

The purpose of the present study was to investigate the effect of experimental T-2 toxin load (2.35 mg/kg of feed) and vitamin E supply in the drinking water (10.5 mg/bird/day) on vitamin E levels of the blood plasma and liver in broiler chickens in a 14-day experiment. It was found that T-2 toxin load did not influence vitamin E content of the blood plasma except at day 3 after the toxin load when a moderate increase was detected in plasma vitamin E. No significant changes were found in vitamin E content of the liver. The simultaneous use of high-dose vitamin E supplementation and T-2 toxin load caused a significantly higher plasma vitamin E content but the changes were less expressed in the group subjected to T-2 toxin load. Vitamin E supply also resulted in a marked and significant increase in vitamin E concentrations of the liver on days 3 and 7 even in the T-2 loaded group, but this concentration significantly decreased thereafter. The results show that T-2 contamination of the diet has an adverse effect on the utilisation of vitamin E in broiler chickens.
