Evaluation of Bio-composit Mycotoxin Binder Based on Rice Husk Biochar, Zeolite, and Sacharomyces cerevisiae on Corn Grain as Poultry Feed Ingredient

Mycotoxins, particularly aflatoxins, in corn pose serious risks in poultry nutrition by reducing nutrient quality and threatening animal health. This study aims to explore the potential of mycotoxin binders derived from biocomposites (rice husk biochar, natural zeolite, and Saccharomyces cerevisiae yeast) in reducing aflatoxin formation in corn. The corn used was freshly harvested corn without drying. There were four types of treatments given, namely control without mycotoxin binder (P0) and three biocomposite treatments as mycotoxin binders (rice husk biochar, natural zeolite, and Saccharomyces cerevisiae yeast) with different balances, namely 1:1:1 (P1), 1:2:2 (P2), and 2:1:1 (P3). Every 200 g of corn was mixed with 1% mycotoxin binder and incubated for five days at room temperature. Parameters observed included moisture content, water activity (aw), density, and aflatoxin content. The research findings showed that the addition of bio- composite (rice husk biochar : natural zeolite : and Saccharomyces cerevisiae yeast) with different balances significantly (P<0.01) affected the water content, Aw, density and aflotoxin levels in high-moisture corn stored for 5 days. This study concluded that the use of a mixture of rice husk biochar, natural zeolite, and Saccharomyces cerevisiae yeast (1:1:1) as a mycotoxin binder effectively reduced mycotoxin levels, decreased water content and water activity, and increased density of corn grain
