Abstract
Mycotoxins in maize are a major concern in poultry nutrition, as they reduce nutrient quality and pose risks to animal health. This study aimed to evaluate the potential of a bio-composite composed of rice husk biochar, zeolite, and Saccharomyces cerevisiae yeast in suppressing mycotoxin presence in maize. The experimental treatments consisted of a control without binder (P0) and three bio-composite formulations with different ratios of rice husk biochar, zeolite, and S. cerevisiae: 1:1:1 (P2), 1:2:2 (P3), and 2:1:1 (P4). Each treatment was replicated four times, with 200 g of maize per replicate, mixed with 1% binder, and incubated in sealed containers for five days. The observed parameters included moisture content measured using a digital moisture tester and mycotoxin indication assessed under UV fluorescence. Data were analyzed descriptively to illustrate trends during incubation. Preliminary results are expected to demonstrate the effectiveness of the bio-composite in reducing mycotoxin indication, thereby supporting the development of safer and more sustainable poultry feed.
