Summary
Hydrated sodium calcium aluminosilicate effectively reduced aflatoxin B1 toxicity in chicks. This safe agent shows promise for preventing aflatoxicosis in poultry by binding the mycotoxin.
Area of Science:
- Veterinary Medicine
- Toxicology
- Food Safety
Background:
- Aflatoxin B1 (AFB1) is a potent mycotoxin that poses significant health risks to poultry.
- Effective strategies are needed to mitigate AFB1 contamination in animal feed.
Purpose of the Study:
- To evaluate the efficacy of aluminosilicates in sorbing AFB1.
- To assess the in vivo effectiveness of hydrated sodium calcium aluminosilicate (HSCAS) in preventing AFB1-induced toxicity in poultry.
Main Methods:
- In vitro assessment of AFB1 sorption by various aluminas, silicas, and aluminosilicates.
- In vivo study using Leghorn and broiler chicks fed a diet containing AFB1 and supplemented with HSCAS.
Main Results:
- HSCAS demonstrated high affinity and stable association with AFB1 in vitro.
- Dietary supplementation with 0.5% HSCAS significantly reduced the adverse effects of 7.5 mg/kg AFB1 in poultry.
Conclusions:
- HSCAS is effective in mitigating AFB1 toxicity in poultry.
- Aluminosilicate compounds, including HSCAS, represent a viable preventive measure against aflatoxicosis.
