In vivo amelioration of aflatoxin B1 in broiler chicks by magnetic carbon nanocomposite

Abstract

In this study an Iron oxide/carbon nanocomposite from maize straw was prepared and was characterized by XRD, SEM, EDX, FTIR, TG/DTA and Surface area analyzer. The adsorbent was fed to different groups of poultry birds along with aflatoxin B1. Different physiological and blood parameters were monitored in order to study the efficacy of the prepared adsorbent for binding of aflatoxin B1 in the gastrointestinal tract of chickens. It was found that adsorbent at dose of 0.3%/ kg feed was highly effective in detoxifying aflatoxin B1 in gastrointestinal tract of poultry birdswith no harmful effects. The high doses given to groups E and F; 0.4% and 0.5% respectively showed slight variation in tested parameters from group A. No negative symptoms associated with the use of activated carbon as previously reported were observed for the adsorbent under study.

Preparation of magnetic mesoporous silica from rice husk for aflatoxin B1 removal: Optimum process and adsorption mechanism

“…According to experiments, the isotherm for AFB1 adsorption on MMS in oil conformed to the Langmuir model; hence, K a was obtained from K L ( Table 1) and the apparent thermodynamic parameters were obtained according to formulas (5)- (7). As shown in Table 7, the values of ΔH (−19.17 kJ/mol) and ΔG (−34.09, −34.61, and −35.15 kJ/mol at 283, 293, and 303 K, respectively) were negative.…”

“…Methods for AFB1 removal include chemical, biological, and physical approaches. Among these, the addition of adsorbents to reduce the bioaccessibility of AFB1 in feeds [ 7 , 8 ] and foods was regarded as an effective and economical method. Sodium coumarin salt or ammonium salt, which easily dissolved in water, could be formed by the reaction of alkali and AFB1 in chemical alkali detoxification, which was suitable for AFB1 removal in oil systems.…”
