Diatomaceous Earth for Livestock Feed

What is Diatomaceous Earth?


Diatomaceous Earth (DE) is a soft, siliceous sedimentary rock containing the fossilized skeletal remains of diatoms.


Diatomaceous Earth is composed primarily of silicon dioxide (Si02). White Lake EarthTM is a naturally pure form of amorphous silicon dioxide and averages over 83.76% Si02, with calcium, magnesium, and other beneficial trace mineral oxides.


What is an Anti-Caking Agent?


Anti-caking agents are added to grain, feed and supplements to absorb moisture that can otherwise lead to clumping and caking. White Lake EarthTM keeps things dry, and improves flowability, while creating an unfavorable environment for mold and bacterial growth.


What is Food Chemical Codex Grade?


To be considered Food Chemical Codex Grade, Diatomaceous Earth must meet a variety of requirements including very low levels of heavy metals like arsenic and lead; White Lake EarthTM satisfies all aspects of the Food Chemical Codex Grade designation.
