Overview
Diatomaceous Earth Feed Grade (Kieselguhr, Amorphous Fossil Silica) is a premium-quality product supplied by ZEAL BIOTECH under strict quality management with full batch traceability. Porous inert mineral used as anti-caking/flow agent and carrier in premix, a mechanical internal/ectoparasite control (the microscopic silica disrupts insect/worm cuticles in feed, grain storage and housing), mild gut toxin/heavy-metal adsorbent and faecal-moisture/odour reducer; also mixed with sepiolite/clay in EU-authorised binder products. Feed-grade amorphous material is essential for safety.
